ESP Light: '02 A4 3.0 CVT

[wallya4]

I just replaced the battery in my A4 and the ESP light will not clear. This is the first time the light has ever come on, except when manually shutting ESP off.

Is there a connection between the two, or just a very strange coincidence?

Thanks
Wally

New cars nowadays dont like when the battery is removed as most of the ECU basic settings will be wipped off ! Remove negative lead and cycle the light switch on and off then reconnect and see if the fault goes away. If it does not clear, then you need to check/erase the faults with a vag-com/diagnostic equipment.

Thanks. It actually cleared itself when I began driving it. I drove less than 100m and it went out. I'll keep your advice for next time!
