Audi A4 Quattro ABS Light Due to Control Module Failure

(26 reports)

The anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.

shop wanted over $1100 to fix. Left it as is. -

ABS Brake lIghyt and Airbag light are on. Heard it was best to get a machanic to plug a scanner in to see if they can communictae with the ABS contro module if no then it should be replaced to fix the issue. Don't go to the dealer thou it's far cheaper to get a rebuilt one and have a trusted mechanic install it. -
Whining noise from the front end while making a turn -

ABS Light came on, I took the car to a local repair shop and they removed the Electronic Control Unit and sent it out to be rebuilt. The brakes still functioned, albeit without ABS, until the ECU was rebuilt and reinstalled. A $500 repair instead of $1500. -
