From day one in August 2013 when I bought this car it burns oil at an extreme rate. A quart every 500 - 800 miles. It calls for synthetic oil by castrol which is close to $10.00 a quart. Do the math. The car manufacture say that is with in the specs for how engine was built. This is truly highway robbery and Audi should be held responsible. I went on Audi forums and thousands of people in the U.S. And the u.k. Complain of the same problem. Please do something about it. I as 50 years old and been paying taxes for 35 years. Working since I was 15 years old. Stand up and do something for a agency that was put in place to do so. I would greatly appreciate it. I look forward to your response.
I picked up my Audi A4 a few weeks ago left the dealer went about five miles and the car starts miss firing bring it back for a new coil pack, one week later oil light came on low oil not even 700 miles and add one 16 oz of oil so started to park car in garage oil on garage floor lots of oil so far not very happy with the car. Bringing it to Audi repair shop they said they will look for the leak. I should have come here first to see, what I see now I would not have brought something other then Audi now waiting to see if it burns or consumes any oil if so should I call the Audi dealer. I paid 9,850.00$
Tl* the contact owns a 2007 Audi A4. The contact stated that while driving at 10 MPH, the vehicle suddenly stalled as the check engine and battery warning lights illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the engine failed and the timing chain needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 126,000.
Car started blowing white smoke and oil consumption increased to 1 quart per 500 miles. Dealership replaced pcv valve, which should have been replaced under csc-10043026-6562. However, since the check engine light never illuminated, the dealership and Audi refuse to cover this issue under the extended warranty, despite the fact that the defective part is specifically called out in their customer service campaign.
I was driving on the highway and felt an extremely hot drop fall on top of my foot while wearing sandals. The pain was so bad I had to stop on the emergency lane to see what it was. There was a brown oily substance leaking from where the gas pedal is right on my foot. I had a pink mark after I cleaned off and kept driving. Got home about 15 minutes later and never felt it again. 2 days later the same thing happened again, also driving on the highway and this time I almost crashed because of the burning sensation on my foot. Once again it was the same oily substance. I went to my very trust worth mechanic and told me it was the heater core? Immediately I knew it was expensive to fix. It's an 8 hour labor job. …
August 2010 at 30K miles, add oil light came on within 2,000 miles of last oil change. Took it into the dealership, they fixed pressure regulating valve. Add oil light continues to come on between oil changes, approx 1K to 3K miles. Dealership stated it was normal for that yr/model. May 2013 at 69K miles, white foul smelling smoke comes from exhaust upon acceleration and car drives rough. Happens intermittently. Dealership states no codes or problems upon test driving. June 2013 it happens again and this time needs to be towed. Dealer fixes fuel injectors. August 2013 happens again on numerous occasions. Dealer does oil consumption test. Fails test. Sept 2013 dealership replaces piston rings and cylinder head. Add oil light continues to come on and white smoke and shaking intermittently. Oct 2013 take back to dealership. They replace turbo. …
Traveling on the freeway at 60mph. The ESP(stability control) and epc lights came on. 5 seconds later the engine shuts off and I keep rolling at 60mph but decreasing speed. Luckily I was on a straight away and there was no need to turn but once the engine turned off the steering wheel was hard to turn and I could not pull over. There was an exit and I was able to stop on the off ramp. After putting the vehicle in park. I took the key out then, put it back on the ignition and tried to turn the vehicle on. The vehicle would not turn back on. When it finally turned on the vehicle stalled back off and the "check engine" light came on. After sitting in the vehicle for 5min in off. I then turned the vehicle on and it started off. …
After a stop light changed to green I started a left turn. Immediately the car started to "shake". It seemed like I was driving over some lane divider bumps. I noticed the engine light was on so I found a safe place to pull over. The car had to be towed. The dealership diagnosed a faulty ignition coil.( all four ignition coils were already replaced in 2010 because of a recall). Again I had all 4 ignition coils replaced. I also had to have spark plugs replaced; (possibly because of the faulty ignition coils ruining some of the plugs. The spark plugs were replaced about 20,000 miles ago.) I was told by the dealership that the original recall of the ignition coils did not cover this event. I feel there should be another recall for the ignition coils and include spark plug replacements.
While driving my 2007 Audi A4 three times over the course of the last month my car has died while driving. Once on the highway, once on a local road, and a third time in a parking lot. All three times Audi claims that "no error code was recorded" yet the check engine light and electronics error light turns on. Because they can't replicate it or see an error they are refusing to do anything to help me other than test drive the car. What evidence do they want? Would me in a body bag after my car quits on the interstate again be what it takes to convince them something isn't working?
