My passenger side rear went recently, and like you I also had the horrible dings and dongs going on in the car with error messages flashing away.

Turns out the caliper had stuck and wouldn't unwind.

I managed to get a guy come over to the house with a VCDS and he was able to get the caliper to wind back using the VCDS.

The car then ended up at German specialists, who ended up replacing the caliper and a control unit of some sort (resides in the boot apparantly), at a cost of no less than 1130 smackers!!!

wasn't best pleased to be honest as apart from the cost, they didn't seem to know what was wrong straight away. I wish I had had a go at it myself now. Does anyone know if these can be overhauled/repaired? I know that the dealers take the old ones back and refund you the surcharge if you return them, so obviously they must be doing something with them.
