P0811
Excessive Clutch A Slippage
Moderate severity
What it means
The TCM detects more slip across clutch A (the first clutch in dual-clutch boxes, or the launch clutch in automated-manual systems) than the calibration allows. Heat builds up rapidly — risk of glazing the friction discs or warping the pressure plate.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
