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.

The contact owns a 2002 Audi A6. While the vehicle was being inspected for emissions 01/10/2011, the contact was informed that the engine was misfiring due to a defective coil. The failure led to damage to the catalytic converter which needed to be replaced along with the coil. The local authorized dealer replaced the coil. The contact called the manufacturer who offered no assistance. The converter was not replaced. The failure mileage was 99,370 and the current mileage was 99,410.

2002 Audi A6 with a belt failure. Consumer states that he did research about this failure and found out other people have had the problem too. He stated that when the water pump and thermostat was replaced or fixed the timing belt was not. The consumer stated his engine overheated and smoke began to emit from the engine. The consumer was informed the water pump to the coolant wasn't functioning properly. Prior to the incident, the check engine light illuminated, faulty coils were replaced and the vehicle had a leaking coolant bottle.

My engine failed while driving at 35 mph on route 375 in woodstock, NY. The failure was a result of assembly bolts on the reverse side of the exhaust cam shaft variable valve timing sprocket loosening and falling out against the cylinder head, stalling the the camshaft and breaking the timing belt. Inspection of bolts show neither a lock washer or thread lock adhesive were present to prevent the loosening due to heating and cooling or vibration. Further service of bolts cannot be performed as there are no tightening specification for these bolts. An easy fix for this mechanical failure would be to remove both valve covers and replace the bolts on the timing gear sprockets with new bolts with adhesive on the threads. This is an interference engine, which results in a catastrophic failure in the bending of valves and total engine destruction.

After a short drive (about 3 miles in town), the car was pulled into my garage a few minutes later my wife noticed smoke coming from under the hood. I backed the car into the driveway, opened the hood and significant white smoke with the smell of burning plastic came from the passenger side of the engine compartment, below the engine, near the firewall. I used a garden hose to extinguish the fire. I could not determine the exact origin of the fire. On Monday, June 27th I reported the incident to Audi of America. A reference number of 50231796 was assigned by Audi to the incident. On June 29th I was contacted by james cruz at Audi who told be that he would be turning the incident over to engineers who would decide what they wanted to do next. On July 5th james cruz called me back and said Audi was not interested in doing any other follow up and that I should just file a claim with my insurance company.

Audi A6 3.0 2005 68,000 mi. Premature water pump failure premature timing belt failure as I was pulling into a shopping center parking spot on 4/25/05, the car began to feel different and the power steering was not working. I shut car off immediately and it was steaming. I turned key on again without starting engine in order to check guages. There was no indication of overheating. Outside the car the coolant had leaked onto the ground. I had it towed by flatbed to winner Audi in wilmington, de. They diagnosed that water pump failed and resulted in timing belt failure, also. Quoted $2380 to repair the timing belt and water pump. Once this is completed, further diagnostics are required to determine if more damage exists. Service advisor, michelle suggested I call Audi for assistance. She said that sometimes they will agree to have the repair done for the customer at the warranty rate, which is half the regular rate. I contacted Audi America customer relations @ 800-822-2834 for assistance. Willie moore took my information and indicated that even though the vehicle was out of warranty, he would review the problem with the dealer for possible assistance with my repair. After putting me off twice, saying that "the department was closed for a few days" each time, he finally called me with an answer after 8 days. The answer was that since the vehicle was out of warranty, Audi would not assist me in any way. I could not help but wonder, why put me through 8 days of waiting and false hope if the answer was as simple as that! all of us knew from the start that the car was out of warranty!
