EPC light and Engine light keep coming on and causing the car to go into limp mode while driving on highway at 55+ mph. This has happened three times. Each time I have taken the car back to Audi Marietta Jim Ellis. Each time I have paid thousands of dollars to remedy the problem. But other issues with the car engine keep arising. I have replaced the entire suspension at 60k miles... and Air struts at 70k. Engine mounts, Transmission mounts, replaced the battery twice. Dealership can not understand why the components are wearing out prematurely. The car is a safety issue and at this point I am fearful when I have to drive the car. This car is a lemon! But Audi will not buy the car back.
Fuel & propulsion system
Suspension was replaced at 40,000 miles do to normal wear and tear. That was Audi excuse. Suspension was replaced again at 63,000 miles. Engine mounts and transmission mounts were replaced at 63,000. Now at 75,000 miles, engine camshaft has failed and almost caused me to lose control of the car. Oil is changed every 3K miles and all maintenance is up to date and always done on time or before required. Car always smell like gas. Inspection found no issues. At this point, I am concerned with the safety of myself and my family because this car is a daily driver. I have contacted Audi of USA for assistance. But Audi is unresponsive. I have all service records but unable to upload due to file size restrictions.
Turbo failure - car stalled while slowing on a major interstate, causing multiple near-collisions. Audi is aware of the issue and the dangers of the failure, but has not issued a recall, even though they have issued multiple technical service bulletins regarding the issue and admitting to faulty parts causing the failure. It is only a matter of time before someone is injured or worse due to losing control of the vehicles acceleration and use of engine.
Suspension
I was driving hit a puddle of water, then all the sudden my power steering went out. I took it in to get looked at, and I'm being told it will cost several thousand dollars to fix the power steering. In addition, this vehicle has air in the suspension, but it now makes sounds when it lifts and takes a longer period of time to lift than normal. Something is effected in my suspension, as well. My vehicle only has 67,689 miles on it, and it should not be having power steering problems from driving through a puddle of water. Lastly, after calling in to Audi, they did a search for the warranty, and Audi did add an extended warranty on the power steering of 125,000 miles or 10 years, which ever occurs first. This means they know about the power steering issue, and with my car being just over 10 years old, the power steering is not covered. …
While driving, received notification of a suspension fault. Was able to drive vehicle home, and found code for suspension C104600. Cleared code, and didn't see it return. Car sat a few days, and next time it was driven, received cascade of MIL warnings for suspension auto leveling failure, auto leveling headlights, adaptive cruise, lane keeping, and auto braking. Console advised to keep speed below 35 MPH. Had to quickly exit the road as result. Limped vehicle home on side roads, found codes across multiple systems. Suspension would not raise, and all coda would immediately return upon clearing. Vehicle was evaluated by local shop, and diagnostics show failed suspension air compressor and relay.
