Frequently Asked Questions
Will this ABS pump fit my 2011 Audi A4 with front-wheel drive?
This specific unit is designed for AWD quattro models with electronic stability control. Front-wheel drive A4 models use a different ABS configuration and would require a different interchange number.
How do I know if my ABS pump needs replacement?
Common symptoms include ABS warning lights on the dashboard, loss of anti-lock braking function, unusual brake pedal feel, or grinding noises during ABS activation. Professional diagnosis is recommended to confirm the pump assembly is the root cause.
Does this ABS pump come pre-programmed for my vehicle?
The pump assembly will require programming and calibration to your specific vehicle using dealer-level diagnostic equipment. Most independent shops with European car experience can perform this service.
What’s included with this ABS pump assembly?
This sale includes the complete pump assembly with integrated valve block and motor. Brake lines, mounting hardware, and electrical connectors are not included unless specifically noted.
Can I install this ABS pump myself?
While mechanically possible, ABS pump replacement requires brake system bleeding, electronic programming, and safety-critical testing. Professional installation by a qualified technician is strongly recommended for safety reasons.
Is this compatible with Porsche Cayenne models?
Yes, our interchange data shows this unit fits 2010-2013 Porsche Cayenne models with the same electronic stability management system. Contact us to verify specific compatibility with your Cayenne’s VIN.
