Sorry to hear this yet again but not surprising. Starter / generators are now on back order so that shows Audi have a world wide problem and do not have the spares, so looks like you could be off the road for a few months. In my case I made enough fuss , although my car was out of warranty, to get Audi to pay the roadside recovery charges and provide a courtesy car until the car was repaired. My current situation is that although Audi acknowledge this failure puts driver and passengers into a dangerous situation they will not commit to a recall or software upgrade. In their view these cars are ‘old’ and the tech dept is working on stuff for 5-10 years time not messing about with old stuff so we are on our own. I am still negotiating compensation but they will not warranty this part for parts, labour, recovery and courtesy car for 10 years as a special deal. They may be able to offer extended warranty free. So I am thinking I will order a spare alternator and have it sitting in my garage, take the extended warranty and get breakdown cover so then I can be sure of getting assistance and repair.
