High pressure fuel pump failure resulting in damage to camshaft, cam follower and internal metal shavings from defect at 123,542 miles.
Oil warning light came on. This is after a 75,000 mile checkup was performed (even though the car has less than 75,000 miles) the car petered out on me, had it towed to the dealership service where I was told it had a blown engine.
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. Took it to Audi and was told they have never heard of that happening on their cars, and seemed to blame me because maybe "I am not maintaining my car well" mean while I am on top of every little thing about that car. They want me to bring it for an inspection on this week, and they said they will have me speak with a service manager after. However in the mean time I am afraid to even drive it again. It was such an expensive car and to have to fix something like this should not be happening. Also the fact that my foot has now been burn twice, this needs to be considered a recall. I almost crashed the 2nd time around and could have injured myself and many others.
Extreamly bad oil comsumption the car uses a quart under 1000 miles and has recieved all of the updates with this problem that Audi offers. This is a manufactuers defect that plague many models and this should be recalled to assist the consumer before its too late.
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.
I have had to replace many coilpacks and diverter valves over the past two years. Several were covered under warranty, but as soon as I was out of warranty I had to start paying for them. They break far too often and are far too expensive to not be covered by Audi.
Since I bought my Audi, I have had to put oil in it many times, and have been told this is normal for a turbo. I think that is crazy, and even an Audi service man told me not all of the turbos do that. I have also had an issue with the car seeming to lose power and jerk about twice a month when I am usually around 70 mph. It's almost as if the ignition is turned off for 1 second, then it acts fine. This is very startling when it happens.
