“2011 Audi A6 seems to be overlooked compared to the rest of the Audi’s yet the Audi has so many different issues such as timing chain such as water pump, such as brake issues, such as rack pinion yet there hasn’t been anyone investigating this in particular make a model it needs to be done for safety reasons. Additionally, I was never contacted for the airbags cars registered DMV and nobody has bothered to inform me of the New airbag issues. What other issues are there brought to one’s attention?”
