Feedback from Audi customer services:
AUDI: TSB are for internal use only please go to your local dealer
I informed them that I had been to my local dealer and they directed me to customer services.
AUDI: They referred my to Erwin Audi, which, at a cost, allows access to TSB, how to guides etc - its really for non main dealer garages.
I replied stating that I want to escalate this beciuase I didn't feel that Audi were taking me seriously and basically 'fobbing me off'.
Keep tuned for they reply
