I am reposting this because I did it just before the site went down, so maybe notifications etc didn't work... I finally took the car back to my mechanic and he has checked all the wiring and the connector and found no problem. He thinks it may be the ABS ECU. Because he only has a handheld VAG-COM unit he has asked me to take the car to Ford as they apparantly can run a better diagnostic and can simulate the sensors to the ABS ECU. This should prove whether the ABS ECU is faulty before I replace it. Anybody any idea how much a new ABS ECU is likely to be? I have seen one on eBay from a breaker with the ABS pump for about

Again, thanks for the quick reply. The car has been driven for weeks since the work was carried-out, the snow prevented me taking the car back sooner. I already saw mention of a 20mph drive required to reset the fault indication. The mechanic told me he could only order a complete unit, he couldn't get the sensor ring on it's own so I would presume he checked the replacement came with one fitted otherwise he wouldn't have mentioned it. I know you can now get the sensor ring separately after reading these forums, but I suppose it depends on his supplier. I will pass all this information on, personally I don't see what else Ford could do except charge me a lot more money... One question though, would VAG-COM still report a mechanical ABS sensor error if it was the sensor wiring? Can he swap the plugs at the ECU to swap over the NSF and OSF sensors or do you mean physically remove the sensors and swap them?

Thanks for the quick reply, I will ask the mechanic to check (if he hasn't already)...

I have a 2005 Mk2 Galaxy. After doing a three point turn (full lock) my ABS dash light came on. At first it would go out after stopping / starting the car. Now it is on all the time. I took the car to an independent garage that I always use and VAG-COM indicates a mechanical failure in the off-side ABS sensor. After checking and cleaning the sensor ring to no avail he replaced the sensor, this made no difference either. Now he has changed the whole CV joint, guess what, same problem!! He has checked the sensor wiring by detecting the sensor resistance and is now stumped. He wants to take the car to Ford, this is going to be expensive... Has anybody any idea what else this could be?
