Audi A4 ABS Module Repair
Brake pressure fault codes on an A4, with the ABS wiring checking out undamaged, point towards the ABS unit itself — a pattern UK garages have documented on this model. Erratic ABS behaviour and a lit warning often come with them. The ABS module controls brake pressure at each wheel and feeds the stability system, so while it is faulty ABS and ESC are normally disabled and the ordinary brakes carry on alone. Have it checked promptly; the ABS light is an MOT fail. Your garage removes the unit and posts it in, and we repair that same unit.
Signs of an A4 ABS Module Fault
- Brake pressure faults logged in the module
- Erratic ABS operation
- ABS and ESC warning lights on
- Brake warning lamp alongside the ABS light
- Faults remaining once the wiring has tested good
Wiring Checked Out?
Start there if you have not: one A4 ABS fault has been traced to a broken wire in the harness at the fuse box, and the sensors and fluid level are worth confirming too. Our A4 ABS diagnosis and repair guide covers the typical signs. If the wiring is sound, describe the fault on the repair form or contact us.
