2012 Audi A4 Avant Engine Problems

“I recently purchased my 2012 Audi a4 after a few weeks the check engine light came on after taking my car to have it diagnosed I was told ( system was to lean in bank 1) I was told I needed a new o2 system, light never went off and I was told next that their was a leak in a vacuum seal and lastly my coolant level was depleting at a rapid speed and I was told that their was a leak from the water pump.”

“Car has been intermittently shutting down while driving. And starting up the car has become more and more randomly justified. Some times it starts up right away, some times it just takes a few cranks. Doesn't matter if it's warm or cold engine. I pulled ecu code and it says u0100 which is loss of communication to ECM. Well this is a safety issue because I can be driving just fine on the road but all of a sudden it just decides to quit cause a havoc on a busy traffic in houston.”

“This car has a massive oil consumption issue. A week after having an oil change the low oil light comes on after approximate 150 miles of driving. I started happening in february of 2017 shortly after the engine malfunction light came on . I took it to the dealership and after they ran the required tests that failed, was told that Audi put the wrong engine in the car and that I would have to pay $8k for them to fix it. This is not my problem, it is Audi's because it is the same issue that they settled in a lawsuit years prior. …”

“I turned car off, went into a store came back, started car and it sounded horrible, as if totally falling apart. Turned it off, tried again and would not start at all. Dealer said engine was shot, seized up has to be replaced. They have been maintaining it since the day I bought it. Oil changes all up to date. 30,000 mile outside of warranty. Dealer has no understand of what could have happened. Could this have happened when I was driving? No idea. Has anyone heard of this happening to their Audi a4 2012?”

“Upon having 3 consecutive oil changes, my car suddenly began to burn oil (no leaks) after the first oil change upon driving less than 900 miles. Then the second oil change did the same thing upon driving under 300 miles. It actually ran out of oil totally. I added oil as instructed by the car, and it burn the oil withing 250 miles of driving. I took it to the dealer, who acknowledge that this model and year had the wrong engine put in the vehicle. They would need to replace the entire engine at my cost, with possible reimbursement to me. Not acceptable, since they acknowledged the defect. …”
