Complete DQ381 wet 7-speed DSG service: six liters of G055529 fluid, the filter and housing seal, drain and mechatronic plug seals, and a fill pump.
If your Golf R, GTI, Jetta GLI, Arteon, Audi A3, S3, TT or TTS has the seven-speed wet DSG and it has started to judder pulling away from a stop, thump into second, or feel lazy on the first few shifts of a cold morning, the cheapest fix to try first is fresh fluid and a new filter. This kit is a complete DQ381 (0GC) fluid service in one box: six one-liter bottles of dual-clutch fluid made to the G055529 specification, the transmission filter with its housing seal, the drain plug washer, the side mechatronic plug seal, a fill adapter that threads into the drain hole, and a hand transfer pump with a bottle clamp.
The DQ381 is the wet-clutch seven-speed that replaced the six-speed DQ250 behind the 2.0 turbo in the hotter MQB cars. Both clutch packs run submerged, so the same fluid cools the clutches, carries the friction modifiers that decide how smoothly they grab, lubricates the gear train and acts as the hydraulic oil the mechatronic uses to engage clutches and move the shift forks. When that fluid oxidizes or loads up with clutch material, the solenoids lose control of clutch slip and the seals inside the valve body start to suffer. The filter is the only thing between that debris and the mechatronic, which is why it is replaced with every fluid service rather than left in place.
Scan the transmission module first. A car with electrical faults, sensor faults or a locked-out mechatronic needs diagnosis, not fluid, and fresh oil will not fix a failed solenoid or a cracked valve body. Our DSG mechatronic and clutch problems guide walks through separating a clutch or fluid complaint from a mechatronic failure, and DSG pressure testing covers checking the hydraulic side when the codes point there. If the complaint is mostly heat related, read how to keep a DSG from overheating as well; old fluid is one of the main causes.
The manufacturer lists this kit for seven-speed DSG cars only: Volkswagen Golf R 2018-2024, GTI 2019-2024, Jetta GLI 2019-2024 and Arteon 2022-2023, plus Audi A3 2.0L 2017-2024, A3 quattro 2019-2024, S3 2018-2024, TT quattro 2019-2023 and TTS quattro 2019-2023. The important check is wet versus dry. Lower-torque VW and Audi models use the dry seven-speed DQ200 (0AM), which takes a small amount of gear oil and has nothing in common with this service. If you are not sure which box you have, check the gearbox code on the build sticker or send us your year and VIN and we will confirm it. You can see every dual-clutch part we carry on the DSG parts page.
Service intervals vary by model year and market, so follow the maintenance schedule for your car and shorten it for towing, track days or heavy stop-and-go use. Shops servicing several VAG gearboxes often add the 0B5 S tronic fill pump kit for the longitudinal Audi seven-speed.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This kit is for the wet-clutch DQ381 (0GC) only. The dry DQ200 (0AM) used in lower-torque models has dry clutches and a small gear oil fill, and none of the fluid, filter or seals here apply to it. Check the gearbox code on your build sticker or send us your VIN to confirm.
The kit includes six liters of G055529-spec fluid, which covers a drain-and-fill. The exact amount that goes in depends on how much came out, so fill until it reaches the level set by the factory procedure at the correct fluid temperature with the engine idling, rather than pouring in a fixed volume.
You need one to check the fluid temperature while setting the level and to run the clutch adaptation afterward. A VW/Audi-capable scanner that can read transmission live data and run basic settings does both.
It often helps when the shudder comes from old, worn-out fluid, because the friction modifiers that control clutch engagement deplete over time. It will not fix a worn clutch pack, a failed solenoid or a mechatronic fault, so scan for codes first.
No. The kit includes a new drain plug sealing washer, filter housing seal and mechatronic side plug seal because reused seals are a common cause of slow leaks after a service, and a leaking DSG loses level quickly.
