DL501 Master Rebuild Kit, new and ready to install. Fits the DL501. Ships fast from the USA.
If your Audi A4, A5, A6, A7 or Q5 with the seven-speed S tronic has started to slip, flare between gears or shudder pulling away, and the scan tool says the clutch adaptation is out of room, the clutch packs are the usual culprit. This DL501 master rebuild kit is the full-overhaul set for the 0B5 gearbox, also used in the 2014-2016 Porsche Macan: an overhaul (gasket and seal) kit, a friction kit and a steel kit in one box, so the unit is resealed and both clutch packs are renewed in a single teardown.
The DL501 is Audi's seven-speed wet dual-clutch built for longitudinal engines. Per Audi's own technology description, the large outer K1 clutch drives a solid shaft carrying the odd gears 1, 3, 5 and 7, while the smaller K2 clutch, nested inside K1, drives a hollow shaft for 2, 4, 6 and reverse. Every shift is one pack opening while the other closes, so both stacks see wear on every drive, and they share their fluid with the mechatronic that controls them. When the frictions glaze, the module keeps adding pressure to hold slip until it runs out of adaptation range. The friction and steel plates in this kit restore both packs; the gaskets, O-rings and seals replace the rubber that hardens with heat and age.
Not every DL501 complaint is clutches. Sonnax documents pressure regulator bore wear in the 0B5/DL501 valve body causing delayed engagement, harsh or soft shifts and erratic line pressure, which then burns clutches. Ross-Tech also notes coolant and water getting into the mechatronic connector, and Audi bulletins covering the internal printed-circuit harness. Replacing plates without fixing those leaves the cause in place.
Read codes and live data with a scan tool that talks to the transmission module. Compare commanded and actual clutch pressure for K1 and K2 on a road test, and check whether the adaptation values sit at the end of their range. If pressure tracks the command but the car still slips, the packs are worn. If pressure wanders, look at the valve body first. Our DSG line pressure testing guide walks through reading those numbers, and the DSG overheating guide covers the heat damage that often comes first.
This kit is listed for the 0B5 / DL501 seven-speed S tronic in the Audi A4 and A5 (including Cabriolet) 2008-2016, A5 Sportback 2009-2016, A6 2011-2016, A6 allroad 2012-2016, A7, Q5 2008-2016 and Porsche Macan 2014-2016. Audi fitted different transmissions to these models depending on engine, drivetrain and market, so a car on this list is not automatically an S tronic. Check the gearbox code on the vehicle data sticker or the transmission case and confirm it reads 0B5. If you are unsure, send us your year and VIN before ordering. Browse every part for this family on our DSG and S tronic collection page.
For the six-speed sister unit, compare our DQ250 clutch and mechatronic guide; the clutch-adaptation logic works the same way.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if that car has the 0B5 seven-speed S tronic. A4 models of that era were also built with other transmissions depending on engine and drivetrain, so read the gearbox code from the data sticker or case. If it says 0B5, this is the kit. Send us your VIN if you are not sure.
The listing describes three kits in one set: an overhaul kit (gaskets, seals and O-rings), a friction kit and a steel kit. It does not include a mechatronic, valve body, drums or bushings, so inspect those parts while the unit is apart.
No. Worn clutch packs are common, but a worn pressure regulator bore in the valve body, a damaged mechatronic connector or an internal harness fault can cause similar complaints. Check commanded versus actual clutch pressure on a scan tool before tearing the unit down.
Yes. Run the transmission basic settings with a capable scan tool: clutch valve calibration and distance sensor calibration, with the fluid in the 40-100 C range. Without it, the module keeps using adaptation values learned on the old plates.
Use the fluid Audi specifies for your gearbox code and fill using the factory level procedure. Our DL501 service kit includes 7 liters of fluid along with the filter, which covers a typical post-rebuild refill.
