A4 ABS Pump Module Repair
Clearing the code only to watch it return the moment the car moves off is a familiar story on the A4 — code 00301, for the ABS return-flow pump, is one example owners report. It suggests a fault the unit detects as soon as it is asked to work. The ABS pump and module keeps the wheels from locking under heavy braking; while it is faulty, ABS is normally switched off and the conventional brakes continue to work. Have it looked at promptly, bearing in mind the ABS light is an MOT fail. We repair the unit you send, and it returns carrying its own coding.

Is It Wiring or the Unit?
A code that returns on every drive can also come from a supply or wiring fault to the unit, so those are worth checking. The A4 ABS problems guide sets out the usual warning signs; then describe your fault on the repair form, or contact us, and we will advise.
