Good morning a

Audi TT 1800 petrol year 2000 165 kw apx engine

abs light on error code 1279 = longitudinal acceleration sensor active

this sensor only exists on 4×4 cars

in Audi they diagnosed that it was the fault of the ECU

We checked if the sensor was getting a signal and it was there and we found out via ALLDATA where it was located and replaced it and deleted the error. The car has been on the road for 15 days now and everything is fine.

Good work
