Well, now I have another EPB problem on the same side.
Usual beeps, messages and icons, the brake was stuck on a bit.
Brake disk not reached.
Clamping force not achieved.
When the EPB is applied or de-engaged, it whirs for about 30 seconds as though a cog has stripped or a cogwheel clutch is slipping.
I removed the motor and operated the EPB and the motor and gear did turn
but noisily. I wound back the caliper with a T45 torx but when I refitted the motor it stuck it put the brake back on and left it there
I think I need to bite the bullet and get a new motor. They seem to start at about £220 which is almost the price of an exchange caliper. I'd rather just get the motor though to save opening the hydraulics and save the core charge while I return my old one and hope they deem it 'serviceable'.
I also notice that some exchange units don't have that thick foil/tin shield all over the plastic motor housing, what is that for? Interference? When you buy a new one from Audi, it comes flat and is self-adhesive you have to stick it on.
Has anyone seen them cheaper that £220?
Will try TPS on monday.
