I have a 2001 Audi A6 quattro 2.8L with P1411 and P1423 dtc codes. I am hearing it is a vacuum hose or combi value problems from what I am reading, common to this model, but I have had several mechanics look at it and not want to tackle it. In a recent forum I was told many of the items I have listed were recall items-including vacuum hoses. Yes, many were, there was even a law suit with Audi, that Audi denied my claim and paid several on. I appealed and they did not respond and did not define why they refused to cover it. Audi still has yet to cover the vehicle in the professional manner I expected. My life burdens are enough, I do not need a car manufacturer or dealer to yank me around, the vehicle now has 205,000 miles, because I paid outrageous car repairs on it. I feel Audi is a good car, but fixing things on it that should be covered under recalls and service warranties is not happening. Do I really have to sue to get results, this is ridiculous! I have experienced check engine light, failed emissions testing, headlight problems, issues with water in lenses and mirrors, turn signal issues, I have had problems with my fuel line, replaced tie rods, and ABS brake light signals after brake repair. I am hoping NHTSA can shed some light and assist me with rectifying my car situation possibly. I have been dealing with these issues for many years now and I am hopeful to receive some relief.
