Electrical recalls for the 2002 Audi A6

Electrical system

06V19800070,512 vehicles affected

The problem
On certain passenger vehicles equipped with halogen low beam headlights, certain connector pins in the headlight switch connector come into contact with each other causing a short circuit. Note: vehicles with xenon low beam headlights are not affected because the circuit in these vehicles contains a fuse, which precludes excessive current flow in the case of a short circuit. Audi s6 and s6 avant vehicles are all equipped with xenon low beam headlights and, therefore, are not longer affected by this recall.
The risk
This condition could lead to overheating or fire.
The fix
Dealers will reroute the wiring harness by installing a jumper wiring harness. The recall began on december 16, 2006. Owners may contact audi at 1-800-822-2834.

The problem
On certain passenger vehicles, if a driver's knees push against the knee bolster (crash element) located under the dashboard, it can contact the headlight switch wiring harness, and an electrical short could occur.
The risk
A fire could originate in the left dashboard area.
The fix
Dealers will install a protective covering on the knee bolster (crash element). In addition, the wiring harness as well as the felt protector on the left side of the dashboard carrier will be checked, and replaced if necessary. The recall began on july 26, 2004. Owners should contact audi at 1-800-822-2834.

The audi was stopped at a stop light when the rpm meter started to drop revs suddenly. Once the car was in motion the engine felt rough. The car was driven 3 miles with no further incidence and was parked for the night. The next day when the car was started in the morning the check engine light came on and the engine started to get very sluggish and shuddering. The car was immediately stopped and the diagnostic codes were pulled. The codes showed multiple cylinder misfires with specific misfires in cylinder 2 and three. The car was towed to an audi dealer where this was confirmed. The dealership mentioned that there was a voluntary recall for exactly this issue. This is a safety issue. *Tr

My check engine light is marking misfire but I have gotten a complete tune-up, changed all 6 coils on the engine changed all the spark plugs, I've done everything possible and changed everything I can that has to do with the engine all brand new and nothing has worked and its still saying misfire...I've googled this problem for audi's and there were so many people complaining about the same thing... Also, I am having a problem with the electrical system as well one day my windows work the next it doesn't sometimes...

my lights will work and sometimes it doesn't, sometimes my radio will work some times it doesn't, the information on my dash sometimes doesn't light up and I can't see anything at night time, I have constantly been to the mechanics trying to figure out what's going on but we can't find the problem, I've spent so much money on this car trying to fix the problems but its really making it hard for me to keep spending money on my car and not being able to figure out what's wrong with it. This is very dangerous because if I'm driving at night time and my lights end up not working I can cause a very big accident I am very very concerned about these defects, my safety and others safety and would really appreciate if you can please investigate this problem because its happened to so many people. I also think something is wrong with the fuel system I'll put $60 in gas and two days later it'll almost mark empty I really don't understand how that is possible but if there's an answer I would really want to know. Thank you so much and I really appreciate your time. *Tr

Driving from nj to upstate ny for ski trip to hunter mountain. Heavy rain during drive up on friday evening, rain all day saturday. Got in the car to go skiing on sunday morning and noticed several inches of water in rear passenger footwell. I was able to bale out some of the water but interior carpeting was soaked. While going to hunter, water was sloshing between passenger footwell and rear. After dropping off the skiers I decided to head home on the ny state thruway. After approx 50 miles - digital dash...

display disappeared, car started to jerk around and buck. Speed was dropped down to 20 mph, I was able to make it to a rest stop. Anyway - remainder of ski party picked me up and I had the car towed back to nj - $700. Mechanic states that tcu unit was under water. Rain water apparently came in through the pollen filter housing and flooded the car. Total damage to the car $2300. There are a number of complaints throughout the internet and various forums detailing this exact problem. I believe this is a design flaw and audi should be held responsible for this problem. I'd like to get reimbursed for my cost. Individuals with this problem should contact audi customer service at 800-822-2834. *Tr

1. Car seized after going through car wash; prior to that, car had experienced odd electrical issues, such as the radio turning itself on and off and the alarm going off for no apparent reason. Car is still under both the audi of america warranty and maintenance programs. 2. Engine seized. 3. The repairs require at least a new engine at the cost of at least $13,000.00. Here is my analysis of why I think audi is trying to prevent this design defect from reaching state and federal regulators. In short,...

I believe that audi is purposefully denying warranty claims to prevent a recall and also to prevent a written record of this defect in the case of class action or personal injury law suit. Specifically, I believe audi of america's legal department has made a very calculated decision: since the damage involves water, most comprehensive insurance policies will cover the damage (in fact, my insurance carrier agreed to cover the claim, although they said they would seek subjugation from audi). For those customers who push hard, audi will cover the repairs out of warranty so that audi will not have to report this defect to state and federal regulators and risk a recall and/or provide evidence in a class action or personal injury law suit. In fact, it wasn't until I explained my suspicions (some of which the service manager at the dealership had confirmed) to an audi of america supervisor that I was able to make any headway beyond, I'm sorry, this is not covered by warranty once I set forth the facts and my analysis of the situation, he changed his manner and explanation immediately. He explained that audi management and legal were well aware of the problem. That audi had made a determination not to cover repairs caused by the clogged drain holes under warranty but that the dealer could request a special out of warranty service and audi of america would reimburse the dealer at 100% of its cost. *Nm

The ignition coils have failed on three separate occasions, which is not only inconvenient but dangerous as the car loses power without warning. Audi admits that the coils are defective but will not replace the remaining three until they actually fail. This makes the car unreliable as well as dangerous as the car loses power without warning. Audi acknowledges that the ignition coils are defective but will not replaced them until they fail. As there are six of them on my car, audi acknowledges that the remaining...

This was the second time a coil failed on my car; the first time was last spring. Audi acknowledges problem but refuses to replace all coils, saying it will only replace those that have already failed, leaving a potential for six failures. Audi says upgraded coils are on back order and are therefore unavailable to most dealers. My dealer has at least two cars waiting for repair. This defect makes the car totally unreliable, since the failure happens without warning and renders the car virtually immobile. Driving it...

after the failure also risks damage to the catalytic converter and other components. There should be immediate notification of owners so they can at least try to avoid late night driving or other situations where they and their passengers might be at risk in case of coil failure. There should be a recall as soon as the coils are available. Dt
