2008 Audi A6 Owner Comments

problem #6

Jan 222013


  • 44,000 miles


The exterior lights go out while driving. This has occurred on all four sides of my vehicle and the passenger front side twice. This is a known problem. The voltage is too high/hot for the the cheap wires Audi used in the their assembly light housing that the wires protective coating is literally burned/melted off exposing the wires. This then leads to the lights and computer chips to go out, and fires to occur in vehicles. There are many reports on the internet reporting this and Audi is aware but refuses to do anything about it three mechanics that I sent my car to also said they see this a lot in Audi vehicles. I was in two near accidents because the tail lights went out while driving and the other car did not see my turn signal or my brake light in the other incident. Some one is going to be hurt by this problem if they haven't already. I have almost twice. I have contacted Audi all five times this has occurred to me but they refuse to cover or assist in this known problem and they then charge over $1200 for each light to be repaired not including labor! I did get one of the rear lights covered but that was because the car was still under warranty.

The wiring harness of both left and right headlight - the electrical wires within the plastic headlight housing going directly to the bulbs are losing their protective wire insulation. The insulation has become excessively brittle and is cracking throughout the entire wire length and in some areas wire insulation has fallen off the wire exposing bare wires. This can only be found when trying to change the light bulb since to access the defect area, the light bulb housing protective cover hiding the defect must be removed. The exposed bare wires cause a fire hazard in the engine compartment. In my car, I have found that while changing the light bulb and maneuvering the harness to have access to the bulb, this has excessively caused the brittle wire insulation to fall off exposing all the head light wires, in some instances several inches long, leaving them without the protective sheathing. Audi has admitted that they have seen this problem on their. I was also told that this happens due to the high current that goes through and the wires cannot handle the load (Audi service manager at braman Audi in West palm beach, fl told me this) but Audi will not address the factory defect.

The head light would work sometimes and others it would not took vehicle the dealer was told must remove bumper and replace head lamp assembly complete the cost would be around $ 800.00after researching specific problem head lamp was replaceable without bumper removal and without headlamp assembly replacement cost $100 price of bulb. Audi of America should be able to troubleshoot this problem very easy and they are purposely trying to rip the customer off. Not to mention the danger a intermittent head light posses on the road dip head light error.

Multiple issues on this car that all came on about the same time. The amb/parking brake module/esp warning lit up, and a few days later the car was not shifting into gear on startup, and when it did shift into gear it shifted erratically and went into neutral on occasion. The transmission control module, ABS sensors both went bad on the car and the car was unable to shift into gear. The car sat at Audi len stoler in owings mills, md for 2 weeks for problem to be diagnosed. They said it was the transmission control module and the ABS sensor that was bad. They replaced the ABS sensor in the hopes that it would resolve the transmission problem! it did not. The bill for the ABS, and a failed driver door lock switch replacement was almost $1400! the transmission control module is a small black box that has the circuitry that controls the transmission. The part alone costs $2600 and with labor it costs almost $4000 - quote from dealer. A 2008 wit 70K and a tcm fails? according to Audi forums, this is a prevalent issue. Audi needs to do the right thing and recall these cars and get this serious issue fixed. It is a design/quality control flaw. The tcm issue also causes the car to not shift right, or go into neutral while car is being driven. Recall these cars before lives are lost (if they have not already been lost). These are significant safety issues and is happening with newer cars. My car has been dealer maintained since new and I am a meticulous owner that does not abuse the car. These are premature failures that should not be occurring at this age and mileage.
