A direct-shift gearbox (DSG, German language: Direktschaltgetriebe ^[1])^{[two] [3]} is an electronically-controlled, dual-clutch,^[2] multiple-shaft, automatic gearbox, in either a transaxle or traditional manual layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic^[2] or semi-manual gear selection. The showtime dual-clutch transmissions were derived from Porsche in-house evolution for the Porsche 962 in the 1980s.

In elementary terms, a DSG automates ii separate "transmission" gearboxes (and clutches) independent within one housing and working as one unit.^{[2] [three] [4]} Information technology was designed by BorgWarner and is licensed to the Volkswagen Grouping, with support by IAV GmbH.^{[ citation needed ]} By using two independent clutches,^{[2] [4]} a DSG tin accomplish faster shift times^{[2] [4]} and eliminates the torque converter of a conventional epicyclic automated transmission.^[2]

Overview [edit]

Transverse DSG [edit]

At the time of launch in 2003,^{[2] [5]} it became the globe'south first automated dual-clutch transmission in a series-production car,^{[2] [5]} in the German language-marketplace Volkswagen Golf Mk4 R32,^{[2] [5]} and soon later worldwide, in the original Audi TT iii.two.^[six] and the 2004+ New Beetle TDI. For the first few years of production, this original DSG transmission was only bachelor in transversely oriented^[two] forepart-engine, front-wheel-drive and Haldex Traction-based four-wheel-bulldoze vehicle layouts.

The first DSG transaxle that went into production for the Volkswagen Group mainstream marques had half dozen forward speeds (and ane reverse)^{[5] [6]} and used wet/submerged multi-plate clutch packs^[2] (Volkswagen Grouping internal code: DQ250, parts code prefix: 02E).^{[six] [7]} It has been paired to engines with up to 350 Due north⋅m (260 lb⋅ft) of torque.^{[5] [6]} The two-wheel-drive version weighs 93 kg (205 lb). It is manufactured at Volkswagen Group'southward Kassel plant,^[2] with a daily production output of 1,500 units.^[5]

At the start of 2008, another earth-kickoff^[five] 70 kg (150 lb) 7-speed DSG transaxle^[5] (Volkswagen Group internal code: DQ200, parts lawmaking prefix: 0AM)^{[7] [8] [9]} became available. It differs from the half-dozen-speed DSG, in that it uses 2 single-plate dry clutches (of similar diameter).^[nine] This clutch pack was designed by LuK Clutch Systems, Gmbh.^[10] This seven-speed DSG is used in smaller front-wheel-drive cars with smaller-displacement engines with lower torque outputs,^{[5] [half dozen] [9]} such every bit the latest Volkswagen Golf,^{[5] [nine]} Volkswagen Polo Mk5,^[9] and the new SEAT Ibiza.^[6] It has been paired to engines with up to 250 N⋅m (180 lb⋅ft).^[11] Information technology has considerably less oil chapters than the six-speed DQ250; this new DQ200 uses just 1.vii litres (0.37 imp gal; 0.45 The states gal) of transmission fluid.^[5]

In September 2010, VW launched a new seven-speed DSG congenital to support upwards to 600 N⋅m (440 lb⋅ft), the DQ500.^[12]

Audi longitudinal DSG [edit]

In late 2008, an all-new 7-speed longitudinal^{[6] [13]} Due south tronic ^[13] version of the DSG transaxle went into series production (Volkswagen Group internal code: DL501, parts code prefix: 0B5).^[7] Initially, from early 2009, it is simply used in certain Audi cars, and just with longitudinally mounted engines. Like the original six-speed DSG, information technology features a concentric dual wet multi-plate clutch.^[13] Still, this particular variant uses notably more plates – the larger outer clutch (for the odd-numbered gears) uses ten plates, whereas the smaller inner clutch (driving even-numbered gears and reverse) uses 12 plates.^[13] Another notable change over the original transverse DSGs is the lubrication system^{[14] [xv]} – Audi now apply ii totally separate oil circuits.^[thirteen] One oil circuit, consisting of 7.5 litres (1.65 imp gal; 1.98 Us gal), lubricates the hydraulic clutches and mechatronics with fully synthetic specialist automated manual fluid (ATF),^[13] whilst the other oil circuit lubricates the gear trains and front and center differentials with 4.3 litres (0.95 imp gal; 1.14 US gal) of conventional hypoid gear oil.^[13] This dual excursion lubrication is aimed at increasing overall reliability, due to eliminating cross-contamination of debris and wear particles.^[xiii] It has a torque handling limit of up to 600 Northward⋅chiliad (440 lb⋅ft),^{[half dozen]} and engine power outputs of upwardly to 330 kW (450 PS; 440 bhp).^[half-dozen] It has a total mass, including all lubricants and the dual-mass flywheel of 141.v kg (312 lb).^[6]

This was initially available in their quattro all-bike-drive variants,^[7] and is very similar to the new ZF Friedrichshafen-supplied^[16] Porsche Doppel-Kupplung (PDK).^{[17] [xviii]}

Operational introduction [edit]

The internal combustion engine drives two clutch packs.^{[ii] [four]} The outer clutch pack drives gears 1, 3, 5^[two] (and 7 when fitted), and reverse^[2] – the outer clutch pack has a larger bore compared to the inner clutch, and can therefore handle greater torque loadings. The inner clutch pack drives gears 2, four, and half-dozen.^[2] Instead of a standard large dry out single-plate clutch, each clutch pack for the six-speed DSG is a collection of iv small wet interleaved clutch plates (similar to a motorcycle wet multi-plate clutch). Due to space constraints, the 2 clutch assemblies are concentric, and the shafts inside the gearbox are hollow and likewise concentric.^[4] Considering the alternate clutch pack's gear-sets can be pre-selected^{[ii] [four]} (predictive shifts enabled via the unloaded section of the gearbox), un-powered time while shifting is avoided^{[two] [four]} because the transmission of torque is simply switched from one clutch-pack to the other.^[2] While the DSG has 1 of the fastest shift times on the market, the claim that the DSG takes only virtually 8 milliseconds to upshift is un-proven with iii-party data nor claimed past the manufacturer.

DSG controls [edit]

The directly-shift gearbox uses a floor-mounted transmission shift lever, very similar to that of a conventional automatic transmission.^[nine] The lever is operated in a directly 'fore and aft' plane (without any 'dog-leg' first movements), and uses an additional push to assist prevent an inadvertent selection of an inappropriate shift lever position.

P [edit]

P position of the floor-mounted gear shift lever means that the transmission is fix in park. Both clutch packs are fully disengaged, all gear-sets are disengaged, and a solid mechanical transmission lock is applied to the crown bike of the DSG's internal differential. This position must just exist used when the motor vehicle is stationary. Furthermore, this is the position which must be assail the shift lever earlier the vehicle ignition central can be removed.

Northward [edit]

Northward position of the floor-mounted shift lever means that the transmission is in neutral. Similar to P above, both clutch packs and all gear-sets are fully disengaged; yet, the parking lock is also disengaged.

D mode [edit]

Whilst the motor vehicle is stationary and in neutral (Northward), the commuter tin can select D for drive (after starting time pressing the foot brake pedal). The manual's outer clutch K2 engages at the start of the bite signal, while on the alternate gear shaft the opposite gear clutch K1 is also selected.^{[ii] [3]} The clutch pack for second gear (K2) gets ready to engage. When the driver releases the brake pedal, the K2 clutch clamping strength is increased, allowing the transmission to drive the wheels. Depressing the accelerator pedal engages the clutch and causes an increment of forward vehicle speed. Pressing the throttle pedal to the floor (difficult acceleration) will cause the gearbox to "kicking down" to first gear to provide the acceleration associated with first, although there will exist a slight hesitation while the gearbox deselects second gear and selects kickoff gear. As the vehicle accelerates, the transmission'southward computer determines when the 2nd gear (which is connected to the second clutch) should be fully used. Depending on the vehicle speed and amount of engine power being requested by the driver (adamant by the position of the throttle pedal), the DSG so up-shifts. During this sequence, the DSG disengages the first outer clutch whilst simultaneously engaging the 2d inner clutch^{[2] [three]} (all power from the engine is at present going through the second shaft), thus completing the shift sequence. This sequence in a fraction of a second (aided past pre-choice), and can be performed without lifting off the throttle, resulting in minimal ability loss.^[2]

In one case the vehicle has completed the shift to 2nd gear, the first gear is immediately de-selected, and third gear is pre-selected.^{[ii] [3]} Once the time comes to shift into third, the second clutch disengages and the beginning clutch re-engages.^[2] This sequence repeats through the gear changes.

Downshifting is similar to up-shifting but in reverse club. At 600 milliseconds downshifting is necessarily slower, due to the engine'due south Electronic Control Unit of measurement (ECU) needing to 'bleep' the throttle so that the engine crankshaft speed can match the appropriate gear shaft speed.^[two] A downshift occurs when the ECU senses the motorcar slowing downwardly, or when more than power is required.

The actual shift points are determined by the DSG's transmission ECU, which controls a hydro-mechanical unit.^[ii] The transmission ECU, combined with the hydro-mechanical unit of measurement, are collectively called a mechatronics ^[2] unit or module. Considering the DSG's ECU uses fuzzy logic, the operation of the DSG is said to exist adaptive;^{[ dubious – discuss ]} that is, the DSG will "learn" how the user drives the machine, and volition progressively tailor the shift points accordingly to adapt the habits of the driver.^{[ citation needed ]}

In the vehicle instrument display, between the speedometer and tachometer, the available shift-lever positions are shown, the current position of the shift-lever is highlighted (emboldened), and the current gear ratio in utilize is also displayed as a number.

Under "normal", progressive and linear acceleration and deceleration, the DSG shifts in a sequential manner; i.e., under acceleration: 1st → 2nd → 3rd → fourth → fifth → 6th, and the same sequence reversed for deceleration. However, the DSG can also skip the normal sequential method, by missing gears, and shift ii or more gears.^[3] This is well-nigh credible if the car is being driven at sedate speeds in 1 of the higher gears with a light throttle opening, and the accelerator pedal is then pressed downwards, engaging the kick-down office. During kick-downward, the DSG will skip gears,^[ix] shifting directly to the most appropriate gear depending on speed and throttle opening. This kicking-down may be engaged by whatever increased accelerator pedal opening, and is completely independent of the boosted resistance to be establish when the pedal is pressed fully to the floor, which will activate a like kick-downwardly function when in Manual operation mode. The seven-speed unit in the 2007 Audi variants will not automatically shift to sixth gear; rather, it stays at 5th to keep ability available at a loftier RPM while cruising.^{[ commendation needed ]}

When the flooring-mounted gear selector lever is in position D, the DSG works in fully automated mode,^{[3] [4]} with emphasis placed on gear shifts programmed to deliver maximum fuel economic system.^{[3] [9]} That means that shifts volition change upwardly and down very early in the rev-range. As an example, on the Volkswagen Golf game Mk5 GTI, sixth gear will be engaged around 52 km/h (32 mph), when initially using the DSG manual with the default ECU adaptation; although with an "ambitious" or "sporty" driving manner, the adaptive shift pattern volition increase the vehicle speed at which sixth gear engages.

S mode [edit]

The floor selector lever also has an S position.^[2] When Due south is selected, sport fashion^[2] is activated in the DSG. Sport mode still functions as a fully automatic mode,^[3] identical in operation to D mode, only upshifts and downshifts are fabricated much above the engine rev-range.^{[ii] [3] [9]} This aids a more than sporty driving mode,^[ii] by utilising considerably more of the available engine power, and besides maximising engine braking. However, this manner does accept a detrimental result on the vehicle fuel consumption, when compared to D manner. This style may not be ideal to use when wanting to drive in a sedate fashion; nor when road conditions are very slippery, due to ice, snow or torrential pelting – because loss of tire traction may be experienced (wheel spin during acceleration, and may also result in road wheel locking during downshifts at high engine rpms under closed throttle). On 4motion or quattro-equipped vehicles this may be partially offset by the drivetrain maintaining full-time engagement of the rear differential in Due south mode, so power distribution under loss of front-bike traction may be marginally improved.

Due south is highlighted in the instrument display, and like D mode, the currently used gear ratio is likewise displayed as a number.

R [edit]

R position of the floor-mounted shift lever means that the transmission is in reverse. This functions in a similar way to D, just in that location is only one reverse gear. When selected, R is highlighted in the instrument display.

Manual fashion [edit]

Additionally, the floor shift lever also has another airplane of performance, for manual ^{[iii] [4]} manner, with leap-loaded + and − positions. This airplane is selected by moving the stick away from the driver (in vehicles with the driver'south seat on the right, the lever is pushed to the left, and in left-hand drive cars, the stick is pushed to the correct) when in D style but. When this plane is selected, the DSG can now be controlled like a transmission gearbox, admitting only under a sequential shift blueprint.

In most (VW) applications, the readout in the instrument display changes to six 5 4 three 2 one, and just like the automatic modes, the currently used gear ratio is highlighted or emboldened. In other versions (e.one thousand., on the Audi TT) the brandish shows just M followed past the gear currently selected; e.g., M1, M2, etc.

To alter up a gear, the lever is pushed forrad (against a spring pressure) towards the +, and to modify down, the lever is pulled rearward towards the −. The DSG transmission can now be operated with the gear changes being (primarily) determined past the commuter. This method of functioning is commonly called tiptronic.^[2] In the interests of engine preservation, when accelerating in Manual/tiptronic mode, the DSG will still automatically change upwardly just earlier the redline, and when decelerating, it will change downwards automatically at very low revs, but before the engine idle speed (tickover). Furthermore, if the driver calls for a gear when information technology is not appropriate (eastward.g., requesting a downshift when engine speed is near the redline) the DSG volition not change to the commuter's requested gear.^[iii]

Current variants of the DSG will still downshift to the lowest possible gear ratio when the kick-downward button is activated during full throttle whilst in manual manner. In Manual mode this kicking-downwards is simply activated by an additional push at the bottom of the accelerator pedal travel; unless this is pressed the DSG will not downshift, and will simply perform a full-throttle acceleration in whatever gear was previously existence utilised.

Paddle shifters [edit]

Initially^{[ when? ]} available on certain^{[ case needed ]} high-powered^{[ quantify ]} cars, and those with a "sporty"^{[ farther explanation needed ]} trim level—such as those using the ii.0 T FSI and 3.2/3.6 VR6 engines^[2]—steering wheel-mounted paddle shifters ^{[3] [4]} were available. However, these are now being offered (either as a standard inclusive fitment, or as a factory optional extra) on most all DSG-equipped cars, throughout all model ranges, including bottom ability output applications, such as the 105 PS Volkswagen Golf game Plus.^[9]

These operate in an identical style as the floor mounted shift lever when information technology is placed beyond the gate in manual manner. The paddle shifters have two singled-out advantages: the driver can safely go on both hands on the steering bicycle when using the Transmission/tiptronic fashion; and the driver can temporarily manually override either of the automatic programmes (D or Southward),^[9] and gain instant manual control of the DSG transmission^[9] (within the above described constraints).

If the paddle-shift activated transmission override of one of the automatic modes (D or Southward) is used intermittently the DSG manual will default dorsum to the previously selected automatic mode later on a predetermined duration of inactivity of the paddles, or when the vehicle becomes stationary. Alternatively, should the driver wish to immediately revert to fully automated control, this can exist done by activating and holding the + paddle^[ix] for at to the lowest degree two seconds.

Advantages and disadvantages [edit]

Advantages [edit]

• Better fuel economic system^{[2] [5]} (up to 15% improvement) than conventional planetary geared automatic transmission (due to lower parasitic losses from oil churning)^[4] and for some models with transmission transmissions;^[2]
• No loss of torque through the transmission from the engine to the driving wheels during up-shifts;^{[2] [4]}
• Short up-shift time when shifting to a gear the alternate gear shaft has preselected;
• Shine gear-shift operations;^[4]
• Consistent down-shift time of 600 milliseconds, regardless of throttle or operational mode;

Disadvantages [edit]

• The clutch pack mechanisms have a limited lifespan;
• Marginally worse mechanical efficiency compared to a conventional manual transmission, especially on wet-clutch variants due to electronics and hydraulic systems;^[4]
• Expensive specialist transmission fluids/lubricants with dedicated additives are required, which need regular changes;^{[14] [15]}
• Relatively expensive to manufacture,^{[ citation needed ]} and therefore increases new vehicle purchase price;
• Relatively lengthy shift time when shifting to a gear ratio which the transmission control unit of measurement did not conceptualize (around 1100 ms, depending on the state of affairs);^[27]
• Torque handling capability constraints impose a limit on afterwards-market engine tuning modifications (though many tuners and users may exceed the official torque limits however); (Later variants have been fitted to more powerful cars, such equally the 300 bhp/350 Nm VW R36 and the 272 bhp/350 Nm Audi TTS.)
• Heavier than a comparable Getrag conventional manual transmission (75 kg (165 lb) vs. 47.5 kg (105 lb));

Issues and recalls of DSG-equipped vehicles [edit]

The 7-speed DQ200 and half-dozen-speed DQ250 gearboxes sometimes endure from power-loss (gear disengaging) due to brusque-circuiting of wires caused past a build-up of sulphur in the transmission oil.^[30]

United states [edit]

In August 2009, Volkswagen of America issued 2 recalls of DSG-equipped vehicles. The outset involved xiii,500 vehicles,^[31] and was to address unplanned shifts to the neutral gear,^[31] while the second involved like problems (by and then attributed to faulty temperature sensors) and practical to 53,300 vehicles.^{[31] [32] [33]} These recalls arose as a result of investigations carried out by the US National Highway Traffic Safety Assistants (NHTSA),^[34] where owners reported to the NHTSA a loss of ability whilst driving.^[31] This investigation preliminary found only 2008 and 2009 model year vehicles as being afflicted.^{[31] [34]}

Australia [edit]

In November 2009, Volkswagen recalled certain Golf, Jetta, EOS, Passat & Caddy models equipped with 6-speed DQ250 DSG transmission because the gearbox may read the clutch temperature incorrectly, which leads to clutch protection way, causing a loss of power.^[35]

Red china [edit]

Since 2009 there have been widespread concerns from Chinese consumers particularly amid the online community, who expressed that Volkswagen has failed to answer to complaints nigh defects in its DSG-equipped vehicles. Typical issues associated with vi-speed DSG include abnormal noise and inability to change gear; while bug associated with 7-speed DSG include abnormal noise, excessive shift shock, abnormal increase in engine RPM, flashing gear indicator on the dashboard every bit well as inability to shift to fifty-fifty-numbered gears.^{[ commendation needed ]} In March 2012 China's quality watchdog the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) said that information technology had been in contact with Volkswagen (China) and urged the carmaker to probe the problems.^{[36] [37]} In a survey held by Gasgoo.com (China) of 2,937 manufacture experts and insiders, 83% of respondents believed that the carmaker should consider a full vehicle recall.^[38] In March 2012 Volkswagen Group China admitted that there could exist an outcome in its seven-speed DSG gearboxes that may bear on approximately 500,000 vehicles from its various subsidiaries in China.^[39] A software upgrade has since been offered for the affected vehicles in an endeavor to repair the trouble.

According to 163.com - one of Prc'due south nearly popular web portals - in March 2012 about a quarter of the complaints about bug found in cars in China's automotive market place were made confronting DSG-equipped vehicles manufactured past Volkswagen.^[40] The acme v models that dominate those complaints were:

• Volkswagen Magotan - 6%
• Volkswagen Bora - v.3%
• Volkswagen Sagitar - 5.three%
• Volkswagen Touareg - four.7%
• Volkswagen Golf game - 4%

Would be worth noting that Touareg has never been fitted with a DSG manual.

On 15 March 2013, Communist china Central Boob tube aired a program for the World Consumer Rights Day. The programme criticized the issue associated with DSG-equipped vehicles manufactured by Volkswagen. On 17 March 2013 Volkswagen Group Communist china announced on its official Weibo that information technology will voluntarily recall vehicles equipped with DSG boxes.^[41] Some sources accept estimated the failure rate of DSG-equipped vehicles sold in China to be greater than 20,000 per meg sold.^{[ citation needed ]}

Sweden [edit]

VW Sweden stopped selling the Passat EcoFuel DSG every bit a taxi after many cars had problems with the 7 speed DSG gearbox. They instead offered the Touran EcoFuel DSG, which uses an updated version of the same DSG gearbox.^[42]

Nihon [edit]

The recall has been extended to Nippon with 91,000 (VW and Audi using the same DSG) being recalled.^[43]

Malaysia [edit]

13 days afterwards the Singapore recall, Volkswagen Malaysia too announced a recall for the 7-speed DSG. No official statement was released past the company, but it was stated that a total of iii,962 were involved in the unit think exercise - units produced betwixt June 2010 and June 2011, with affected vehicles being Golf, Polo, Scirocco, Cross Touran, Passat and Jetta models equipped with the transmission.^[44]

Australian recall [edit]

xv October 2019, Commonwealth of australia think of DSG seven-speed gearboxes. Due to a production fault, over time a fissure in the transmissions pressure level accumulator can occur. If the pressure accumulator cracks, oil and force per unit area is lost in the hydraulic system of the gearbox. Equally a result, the transmission of engine power via the gearbox is interrupted. The experience of this symptom would exist comparable to depressing the clutch in a vehicle fitted with a manual manual. This could increment the likelihood of an accident affecting the occupants of the vehicle and other road users.^[45]
