Timing chain tensioner failed causing engine damage and almost caused a severe accident. While driving vehicle lost almost all power and decelerated to a 15 MPH pace on major street with 45 MPH speed limit.
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?
Extremely loud "roaring" noise on a cold start after having sat overnight. Dealership basically reported as normal "of no consequence". Continuous since new.
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.
Only five minutes after starting car in morning, engine rapidly lost power and quit completely while in 60 MPH traffic on heavily traveled interstate 526 in charleston, sc. Coasted car out of traffic lanes to side, a very dangerous location on elevated roadway. Had car towed to audi dealer, who said they tested and found fuel pump had failed. They replaced fuel pump and engine seems to run normally now. In four decades of driving I've never had a fuel pump fail. This one put my wife and me in jeopardy due to the sudden and complete loss of engine power in middle of fast, heavy traffic. We were lucky to get out without being hit by oncoming trucks & traffic.
At approximately 1000 miles on the odometer of my 2012 audi a4 avant quattro, a strange noise began from the front area of the engine. The noise happens at the first startup of the engine regardless of ambient temperature. After about 2 minutes when the engine idles down the noise stops. Different audi technicians at two dealerships have diagnosed the noise as 1) cam tensioners, 2) a bad bearing inside the cam case, 3) secondary blower motor and, 4) lash in the vvt system. None of the technicians have put a wrench on any of the named components because, according to the dealerships' service managers, audi USA will not authorize repairs. According to audi USA, the strange noise is a normal function even though audi customer service cannot explain why the noise was not apparent for the first approximate 1000 miles of driving.
