DL501 Valve Body 2010-2016, remanufactured and ready to install. Fits the DL501. Ships fast from the USA.
Between 2010 and 2016 the DL501, Audi's 0B5 seven-speed S tronic, was the dual-clutch gearbox behind quattro engines in the B8 and B8.5 A4, A5, S4 and S5, the 8R Q5 and SQ5, and from 2012 the C7 A6 and A7. Owners of these cars search for this part after a late, clunky engagement into Drive, a hard hit coming to a stop, shifts that are harsh one drive and soft the next, or a flashing gearbox warning followed by limp mode. When the electronics check out and the problem is hydraulic, this remanufactured valve body for the 2010-2016 run replaces the worn piece without paying for a whole transmission.
The 0B5 has two separate oil systems. One feeds the two wet clutches, the mechatronic and the oil supply with a dedicated ATF; the other lubricates the gear set, center differential and front axle drive with gear oil. The valve body lives on the ATF side. Its pressure regulator sets main line pressure, its clutch valves meter apply pressure to K1 (odd gears) and K2 (even gears and reverse), it routes oil to the gear actuators that preselect the next ratio, and it controls how much cooling oil flows across the clutch packs. The control unit trims clutch pressure constantly to manage slip, so any leakage past a worn valve or bore shows up directly in engagement and shift quality.
Early 0B5 units carry two common non-hydraulic faults that mimic a bad valve body, so rule them out first. Water and coolant intrusion at the mechatronic connector is not unusual and leaves the control unit throwing random codes or refusing to communicate, with U-codes such as U0100 alongside. Audi also issued bulletins on the internal printed-circuit wiring. Inspect the connector for corrosion, check for a software update, and clear the clutch adaptations. If delayed engagement, erratic pressure or the stopping shock come back after that, worn pressure regulator and clutch valve bores are the likely cause. Read our dual-clutch line pressure testing guide before you pull the pan, and the DSG overheating guide if the trouble only shows up hot.
This listing covers the DL501 / 0B5 for 2010 through 2016, the B8-era and early C7-era production. Audi revised the hydraulics, sensors and software several times inside that window, and 2.0T, 3.0T and RS applications are not always the same part. Read the part number off the label on the unit you are removing and match it, or send your year and VIN and we will confirm before it ships. The transverse DQ250 and DQ500 in VW and smaller Audi models will not interchange. For 2014-and-later cars, compare with our DL501 valve body for 2014-2024. The full range is in our DSG and S tronic collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 0B5 seven-speed S tronic in quattro models of that era: B8 and B8.5 A4, A5, S4 and S5, the Q5 and SQ5, and the C7 A6 and A7 from 2012. Revisions vary by engine and year, so match the part number on your unit or send us your VIN.
On early 0B5 units it often is. Coolant or water at the mechatronic connector causes random codes and communication faults. Check and clean the connector before replacing hydraulic parts.
The clutch and mechatronic side uses ATF to Audi spec G 052 529 A2. The gear set, center differential and front drive use a separate gear oil, filled and checked on their own.
Run the basic settings with a capable scan tool and the fluid at 40 to 100 C: clutch valve calibration, then distance sensor calibration, then clear codes and road test. Some replacements also need component protection cleared.
It is the remanufactured valve body for the DL501. Confirm with us how your existing control electronics carry over before ordering if you are unsure what your failed part includes.
