Well not the best news this morning. Apparently there are 12 server motors that work the flaps on the air vents. These are known by Audi to be a poor part that fails and they now use a different motor. The software I mentioned yesterday is an update for the vehicle, not diagnostics, hence why I have to pay for it. They have now done the software update but there is a problem with the settings so it’s going to have to be run again. However, what they do know for sure is that at least 2 motors have failed behind the heater box so they will have to be changed at £261 + vat + labour. Audi recommend that when 1 fails all 12 should be replaced which means dash out and many hours of work - the Specialist is not recommending that at this point. Fingers crossed when the software runs again it still finds only the 2 fans actually need replacing (apparently these can be accessed by taking glove box off and a panel near foot pedals). My estimated bill is currently £1350 subject to nothing else being found. I find I staggering that a manufacturer like Audi have allowed the use of clearly substandard parts - car has only done 36k, has been well cared for and is not really that old. As soon as job is done it will be sold.
