P081EExcessive Clutch B Slippage
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P081E is the counterpart to P0811 for clutch B – on a dual-clutch gearbox clutch 2 with the even gears and reverse, which Audi calls 'clutch 2'. The module compares engine speed with the input shaft speed of the closed clutch and flags slip above its limit. Audi's DL382 S tronic (2020–24) sets it intermittently with P0811 and input speed codes; the bulletins report a transmission malfunction and 'reverse gear unavailable', and the fix was a new transmission module with improved parts from late 2023. A failed clutch 2 typically means no reverse and no even gears.
