I have a 2001 A4 1.8T 5 speed (all stock).

Does anyone know how to reset the "service engine" warning from the computer?

Please help, it's driving me crazy.

Thanks,

Ted...

According to my Owner's Manual for '01 A6 >
-button # 1 on left side, near tach
-button # 2 on right side, near speedo.

1. ignition off
2. hold button #2 down, turn ignition on , "Service!" appears in diplay.
3. press button #1 until "Service!" is cleared.

It's probably the same for the A4, but not certain.

yep that worked for me
