Both motors had been replaced previously due to the usual corrosion/cracks/seizure issue, but I's still get occasional yellow or even red brake errors on the dash.
Put it down to an adaption issue, but couldn't get it right. re-adapted and even replaced the rear pads again - no dice.
Bought a second EPB "ECU" - but it wouldn't code to the 4.2 TDI as it was from an older model. Needed t sorted for the MOT so bit the bullet, local dealer had one in stock (says a lot I suspect), fitted, coded and issue resolved.
Never had an issue for the next year or so "Mechcanico Lee" will be able to confirm if he has had any issues since
