DQ250 DSG Service Kit with Filter, Seals and 5L Fluid

Searching for a DSG service kit for a 2006-2018 GTI, a 2009-2017 CC, a 2010-2018 Passat or an Audi A3 or TT quattro usually starts with a car that has begun to judder from a stop, slur the 1-2 shift or feel worse once it is fully warm. On the six-speed wet DSG, the 02E or DQ250, that is very often oil that has done its job and needs replacing. This kit, part number 02E305051CKIT2, packages the whole service so you are not hunting parts: the internal oil filter, the filter housing O-ring, a new drain plug sealing washer, a fill adapter and five one-liter bottles of FEBI DSG dual-clutch fluid (FEBI 39070 on the label).

What the oil and filter do inside a DQ250

The 02E is not built like a planetary automatic. Volkswagen's Self-Study Program 308 describes one common oil circuit for the whole gearbox: the same 7.2 liters of DSG oil apply the two wet multi-plate clutches K1 and K2, carry heat out of them, operate the gear-selection hydraulics in the mechatronic and lubricate the gear wheels. A crescent-type pump, turned at engine speed by a shaft running through the two input shafts, can move up to 100 liters per minute at a main pressure of about 20 bar. All of that flow passes the oil pressure filter mounted on the case next to the oil cooler. Every launch and every shift slips a clutch in that oil, so the friction additives wear out and fine clutch material circulates long before the gears show any wear. The filter is what stops that material from reaching the mechatronic valves.

Symptoms that say the DQ250 is due

• Shudder or judder creeping in traffic or pulling away gently
• Harsh or delayed engagement into Drive or Reverse
• Flare or bump on the 1-2 or 3-4 shift that gets worse when hot
• Clutch temperature or pressure faults stored in the transmission module
• Dark, burnt-smelling oil from the drain, or no record of a DSG service by around 40,000 miles

How to confirm before you order

Scan the transmission module first. A fluid service restores clutch feel and shift quality, but it does not repair a cracked valve body, a failed pressure sensor or a burned-out solenoid. Our DQ250 mechatronic and clutch problems guide walks through separating a fluid complaint from a mechatronic or clutch-pack failure, and the DSG overheating guide explains the clutch-oil temperature readings worth checking. If the codes already point at the hydraulics, plan for a DQ250 mechatronic solenoid kit and still change the oil, because new parts in old oil do not last.

Fitment by vehicle and year

The listing covers the 02E six-speed wet DSG in these Volkswagen models: Beetle 2012-2016, CC 2009-2017, EOS 2007-2016, Golf TDI 2010-2015, Golf Alltrack 2017-2019, Golf R 2015-2017, GTI 2006-2018, Jetta 2006-2016, Jetta TDI 2005-2014 and Passat 2.0L and 3.6L 2010-2018. On the Audi side it covers A3 2006-2016, A3 quattro 2006-2018, S3 2015-2017, TT 2008-2009, TT quattro 2004-2018 and TTS quattro 2009-2018. Several of those model lines were also built with other gearboxes: the seven-speed dry DQ200 (0AM), the DQ500 and, on later cars, the DQ381. This kit fits none of them. Check the gearbox code on the case or the build sticker and compare your filter to 02E305051C, or send us your year and VIN and we will check it. Every other dual-clutch part we carry is on the DSG collection page.

Install notes

• Work with the car level on a lift so the level check is accurate later.
• Remove the filter housing on top of the case and fit the new filter with the new O-ring before draining, so the dirtiest oil in the housing does not run back into the case.
• Drain, fit the new sealing washer to the drain plug, and refill through the fill adapter. If you need adapters for other VW and Audi gearboxes too, the 26-piece ATF fill adapter kit covers them.
• A drain does not empty the clutch housing or mechatronic, so expect the refill to be well under the 7.2-liter total. Set the level at the specified oil temperature until it runs from the check, not by pouring in a fixed amount.
• Use only DSG oil to the G 052 182 specification; conventional ATF is not a substitute.
• Finish with the clutch adaptation basic setting (oil 30-100 C, lever in Park, engine idling) so the module relearns engagement points on the fresh oil. A DSG adaptation scan tool will run it.

Does this kit fit my 2015 Golf R or 2017 Golf Alltrack?

Both are on the fitment list (Golf R 2015-2017, Golf Alltrack 2017-2019), but only when the car has the six-speed 02E wet DSG. Confirm the gearbox code or send us the VIN before ordering.

Why are there only 5 liters when the DQ250 holds 7.2?

7.2 liters is the total for a dry gearbox. A drain-and-filter service leaves oil in the clutch housing, cooler and mechatronic, so the refill is less. Fill to the level check at temperature rather than by volume.

Is this the same kit as your other 02E service kit listing?

Yes, it is the same contents: filter, housing O-ring, drain washer, fill adapter and five liters of FEBI DSG fluid. This listing carries the detailed year-by-year fitment list, so use it to confirm your vehicle.

Will this fit a DQ200 seven-speed or a DQ500?

No. The DQ200 is a dry-clutch gearbox with a different oil system, and the DQ500 uses its own filter. This kit is for the 02E six-speed wet DSG only.

Do I have to reset anything after the service?

Running the clutch adaptation basic setting afterward is recommended so the transmission module relearns clutch engagement on the new oil. It needs the oil between 30 and 100 C and the correct level.
