Check engine light by model year
What owners say
August 12, 2017 car was parked in a target parking lot. Went to start and car lights and radio came on but engine wouldn't turn over. Also check engine light became illuminated. Next day car was towed to quad cities audi to service dept. Audi service dept finally got around to looking at car on friday sept 1. They state that " found timing to have jumped causing valves to come into contact with pistons and bend." their repair suggestion states " r&r cylinder head and send to machine shop to determine how many valves need to be replaced. Replace timing chains, guides and tesioner." quoted $3,729 to fix, plus $595 for diagnosis. Car is currently at that dealership being worked on.
Came into the garage in the morning and realized there was oil on the ground. The next day took the car to the shop to have them looked at to see where the oil leak is coming from. After diagnosis the result was that rear main seal needs to be replaced with the pcv valve. Total price is about $1500. I did not have any check engine light and this seems like it is a known issue with audi vehicles where the pcv valve is over pressuring the engine and causing gaskets/seals the blow. I believe this should be the responsibility of the audi to fix this problems since this is a known issue and has been reported a lot of 2.0t engines.
Since the moment I purchased this vehicle in 2012, I've had nothing but constant issues. This vehicle has stopped in the middle of the street on the freeway (surprised I was not hurt because of this). I've had engine lights on, check oil level lights on, alternator going bad, esp lights on, bearings replacement. You name it, its happened. I took my audi in for an appraisal and turns out the transmission is going bad, had warranty and audi services did not mention any issues with my transmission, wasn't until my warranty had expired when I found this out. This vehicle should be recalled.
Tl* the contact owns a 2009 audi a4. While the vehicle was parked, the contact found oil spills under the vehicle. While driving at various speeds, the engine warning light illuminated. In addition, the contact mentioned there was a burning odor of oil coming from the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed that the rear main seal of the engine's crankshaft needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 51,000. The VIN was not available.
The timing chain tensioner failed causing the audi interference engine to become out of sync resulting in the engine becoming totaled. This has become a common occurrence and is widely reported on 2009 and newer models. Below is an article with their assessment of the situation. The car had been taken in 2x for misfires and was diagnosed as an issue with the spark plugs, it is now clear that this was the timing chain being out of alignment and missed. Upon the engine light coming on the car was left parked until the day before the service appt when it was to be dropped off at the service location, at that time, upon starting the vehicle the timing chain tensioner failed and caused the engine to fire out of alignment damaging the engine. When speaking to a member of the audi dealership it was shared that another vehicle is in for the same issue and that they are seeing this occur more and more in their vehicles. This failure is also reminiscent of the 2007 class action law suit which prompted audi to move from a timing belt to the for the same outcome occurring. Http://redlinespeedworx.com/2-0t-tsi-timing-chain-failure/ if audi had placed out updated parts, I would like to know why there was no recall to replace the part or anything mentioned by the manufacture indicating the release of updated hardware to address a "potential issue"

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.
