No repair was required and there was no charge as the car is under warranty. The original trigger for this code remains unexplained. |

turbocharged 211hp 2.0L I4 8-speed shiftable automatic AWD
| 94000 mi | Just after 80,000 miles, my A4 began burning oil excessively. This was because of the known oil burning issue covered under the class action lawsuit up to 80,000 miles. Audi USA refused to assist in the repair - estimated at $7,000. |
| 103000 mi US $9000 |
My 2011 Audi A4 continues to burn oil at an alarming rate. Currently the reading will go from max to min within just over 1,000 miles. The issue became severe and was first looked at just over the 80,000 mile class action lawsuit warranty repair period. Audi USA refused to offer any assistance for what is clearly a manufacturing defect. I was quoted between 6k-9k to repair the issue myself, which means my car is totaled by this Audi manufacturing issue. |
| 112000 mi | Engine stalled twice while driving. Had it towed to the dealership where they determined it was a failing fuel pump. While it was in the shop, I also had regular maintenance performed. |
| 3100 mi | Transmission shifting roughly in 1st and 2nd gear both upshifting and downshifting. Dealer performed software upgrade for the problem. It is now definitely better, but not as smooth as I would like. |

| 63000 mi | If I had continued with the test they say it would have been enough to cover the piston and ring replacement, but I did trade it before completing the test. |
| 19000 mi | The car randomly stuttered then the engine would turn itself off. After several days of doing this eventually would not start at all. Replaced fuel control solenoid. |
| 42000 mi | The coil packs on each cylinder were replaced. The car was idling very rough, EPC and engine light came on while driving. |

| 115000 mi | car had oil consumption problem when we purchased it, previous owner did not disclose and it was 2k miles out of warranty. Audi would not extend or honor warranty outside of 80k. Seperate issue- car lost power going up hill. Mechanic said it was the timing chain (supposed to be lifetime). He said they are repairing at least one timing chain a week because they "stretch out" and then fail. When they fail you have to replace the entire engine. Parts and labor quoted by several shops 10k-12k depending on if purchase a used or new engine. We are going to walk away from the car. It was a pleasure to drive, beautiful, and we absolutely loved it. But we have a hard time with a company and/or product that has major defects and consumers are not told about it or have to pay for major design flaws. The car was a ticking time bomb. |

Low oil pressure light came on and engine sounded rattly. After a few minutes Check Engine light also on. The problem happened in early evening so I let the car sit overnight. I started the car the next morning and there was no low oil pressure warning but the engine still sounded rattly and the check engine light was still on. I called for a flatbed to get it to my mechanic but due to a snowstorm the truck took 4 hours to arrive and when I started the car to move it out of my driveway the problem was gone, no engine rattle. I still had it taken to the garage but aside from resetting the CEL they could not find any problem. It had been quite cold (-20C) so they think that had something to do with it. I always run synthetic oil so it shouldn't have been an oil flow problem. They don't think it was actually low oil pressure as the CEL was unrelated but the engine noise to me seemed to point to it. |
