I own a 2009 Audi A4 with 63,000 miles. The Audi dealer change the pistons and rings in my vehicle due to an oil consumption problem two weeks ago. On November 4, 2014 my check engine light comes on and the car is idling up and down constantly when at a stand still. The service department informed me that the intake manifold failed internally and wants to charge $935 plus tax to repair. Under second opinion I was informed that this is a part is highly unlikely to fail and should have been inspected with the piston repair work was completed. Dealer claimed that they road tested the vehicle and everything seem fine. Contacted Audi usa to see if they will help, I have been a customer of Audi for 13 years.

After having my car for a year, it started to burn through oil at an increasing rate. Currently it is going through about 1 quart of oil every 1000 miles. I have taken the car in a few times to check for leaks or try to determine the location where it is going and have just been told that this model engine goes through at a faster pace and has been a common complaint amongst customers. In addition to this I have dealt with having to get the sunroof re-lubricated every few months, dealing with rattles in the doors, warping of the interior (dash, door panels, seat backs), and a one-time failure with the door latch not working during cold temperatures.

Used oil, 1 quart per 450 miles. It was determined that the piston rings needed to be replaced. It is leaking and burning oil car is 3.5 years old 72K miles. I was told and from what I've read this is a common theme with this car.

When I called the nearest dealer for a scheduled maintenance for 55000 miles, I was informed of a recall involving the camshaft. By phone, they told me that there was no charge for this work and it would take about two hours. I delivered the vehicle at 8 am and at 11 am I received a call. They said that they would begin the recall work, but it was a recall that involved the 50000 mile warranty. I was nearing 55000 miles, but they would due the work under warranty. At 2 pm, I was informed that there was internal damage to the engine and they would need to keep the vehicle for several days. They provided a rental car until they completed the work. My complaint is that I never received any notice"?" the service manager told me that the issue with the camshaft problem went out in June 2011. That was one month after the Maine dealer performed my 35000 mile maintenance!!! the point is that the longer I drove the vehicle, the worse the problem progressed. They said that eventually, I would loose the engine.

This Audi was a lemon from the start and botched repairs at the dealer have only made it worse. One the 2nd day we owned the car the oil light came on and we had to return it to the dealer for more oil. Over the next 2 years the car burned an excessive amount of oil starting at 1 qrt every 2500 miles and deteriorating to 1 qrt every 800 miles. All along the dealer told us this was "normal". in May 2011, dealer told us that Audi had initiated a testing program and if the car failed they would do something. In June 2011, the car failed test and the dealer kept the car for 3+ weeks conducting major engine surgery. 6000 miles later we took the car in for routine maintenance and they said they wanted to do routine warranty work. In the course of this work, they destroyed the timing chain and pistons of the car. 1 week later the transmission failed. In talking to Audi technicians at other dealers (off the record) they say that the oil problem is a design problem and that the fixes are simply bandaids. Appears that the 2012 model has been redesigned to fix the engine flaw. The net effect is that the car has visited the Audi dealer on at least a monthly basis since we bought it and has spend more than 8 weeks in major "warranty related" engine repairs. To top it off, Audi has complimented this "worst in class" product experience with a "worst in class" customer service experience as Audi America 1-800 people have been consistently either robotic or rude in talking with us about this issue. Most recently, they made a lame offer to reimburse us for towing expenses and extend the warranty on this dubious car for another 12 months. Amazingly, they refuse to pu T the offer in writing until after acceptance. Presumably so that they can avoid legal issues. Please help. I am sure I'm not the only one suffering this.
