DQ250 Master Rebuild Kit

This DQ250 master rebuild kit is aimed at the shop or owner overhauling a 02E six-speed wet DSG from an Audi A3 or TT, a Skoda Octavia or Superb, or a VW GTI, Jetta, Passat, CC, Scirocco or Eos. It bundles three kits in one set: an overhaul kit with the case and valve body gaskets, seals and O-rings, a friction kit and a steel kit for both clutch packs. If the gearbox is coming out for judder, slip or leaks, this is everything that wears or hardens in one order.

What the master rebuild kit does in a DQ250

The 02E runs two wet multi-plate clutches in one housing. VW's training material assigns the outer K1 clutch to 1st, 3rd, 5th and reverse and the inner K2 clutch to 2nd, 4th and 6th, with the mechatronic modulating each pack through its own pressure control valve, N215 for K1 and N216 for K2. Clutch oil is cooled through a separate low-pressure circuit metered by N218. When the plates wear, holding torque falls and the module raises apply pressure to compensate, which adds heat. A worn pack plus a tired cooling circuit is how a DQ250 ends up flashing a gearbox warning. Renewing frictions and steels resets the clutch side; the overhaul kit reseals the case, the valve body plate and the shafts.

Symptoms that call for a full DQ250 overhaul

• Judder from a stop or while creeping, often worse once the fluid is hot
• Slip or rpm flare on shifts, or a loss of drive in one half of the gears
• Clutch adaptation codes such as P189C (clutch adaptation reached its limit)
• Dark, burnt fluid with clutch debris at the external filter
• External leaks at shaft seals or the mechatronic cover on a high-mileage unit

How to confirm before you buy

Do the diagnosis before ordering a full kit. With a scan tool, compare commanded and actual K1/K2 pressure on a road test and check the adaptation values. Because the mechatronic and its pressure senders can mimic worn clutches, our DSG line pressure testing guide covers the key-on sensor check and how to read the pressure data. Sonnax notes that many DQ250 hydraulic wear points can be repaired at the valve body level, so a worn mechatronic is not always a full replacement. Our DQ250 problems guide explains how to tell the two apart.

Fitment

The kit is listed for the 02E DQ250 in the Audi A3 (1.8, 2.0 and 3.2L), Audi Q3 2013-2014, Audi TT 2003-2014, VW Golf/GTI 2004-2014, Jetta 2005-2014, Passat and Passat CC 2006-2014, Beetle 2003-2014, Eos 2006-2014, Scirocco 2008-2014, Caddy, Sharan, Touran and Tiguan applications, plus Seat Alhambra, Altea, Leon and Toledo and Skoda Octavia, Superb and Yeti. Many of those names cover markets outside North America, and the same models were built with other gearboxes, including the dry-clutch 0AM. Confirm that the code on your transmission reads 02E, or send us your year and VIN. See every DQ250 part on our DSG collection page.

Install notes

• With the gearbox on the bench, remove the mechatronic, pull the dual clutch with a wet DSG puller and strip both packs.
• Inspect the pump and the clutch housing while it is apart. Our DQ250 pump is worth having on hand if the gears or housing show scoring.
• Set clutch clearance with the new plates dry-stacked, then pre-soak the frictions in clean G 052 182 fluid. Use every seal and gasket in the kit rather than reusing the old ones.
• Refill to the correct level with G 052 182 and fit a new filter, then run clutch adaptation and basic settings. A DSG adaptation scan tool handles that step.

Overheating history? Read the DSG overheating guide and check the cooler before the new plates go in.

Is this kit for the 02E or the 0AM DSG?

The 02E (DQ250) six-speed wet dual-clutch only. The 0AM (DQ200) seven-speed uses a dry clutch and a different design. Read the gearbox code on the transmission case before ordering.

What comes in the master kit?

Three kits in one set: an overhaul kit (gaskets, seals and O-rings), a friction kit and a steel kit for the K1 and K2 clutch packs. It does not include the mechatronic, pump or clutch housing.

Will new clutches fix a P189C code?

Only if the packs are actually worn. P189C means the module ran out of adaptation range, which worn plates can cause, but so can a pressure or mechatronic fault. Compare commanded and actual clutch pressure first.

Does the US Tiguan use this transmission?

The fitment list includes Tiguan applications, but those are market specific. Check the gearbox code on your vehicle; if it is not 02E, this kit will not fit. Send us your VIN and we will confirm.

What do I need to do after the rebuild?

Refill with G 052 182 DSG fluid to the correct level with a new filter, then run clutch adaptation and basic settings with a scan tool while the fluid is within the specified temperature window.
