ABS Unit

Post by Laif » Mon Feb 24, 2025 8:54 am

Hi everyone. I am looking for an ABS unit for my C5 RS6. I have 3(!) of them and none work. Tried to overhaul a couple, no dice. Last one showed up and electronic side was shot. One showed up but was from an allroad and they do not work - when we hooked it up it seized all wheels. Car is driveable, but no ABS and a ton of flashing lights on the dashboard. Any help and direction is greatly appreciated. Thank you.

You original one, has it been to be tested by some one like ECU testing to be checked and maybe repaired.

I had good results getting mine repaired by them.

I second what Felix has commented - I have not had the need to use ECUTesting, but have heard plenty of good reviews over the years. As a trained electronics engineer, this is who I would choose, they have a great premises with all the right tools.
The price is good too considering the cost of a new unit (what my cars previous owner did).
