my first post here. I have a 2007 A4 2.0T with 101,400 miles. The car has been running fine . I went to start it two days ago it was 5 deg. outside. It fired right up and started to make noise ticking I was thinking it was cold and let it run as it ran for about 3 to 4 minutes it got louder to a diesel sound . I shut the car off and checked the oil it was fine. Started it back up let it run for another couple minutes and it locked up. i didn't have a oil light or any codes.
Towed it to the dealer and they said you are 1,400 miles out of warranty. They told me the cam seized in the head. I had the cam follower for the fuel pump 20k ago. at the dealer under warranty.
I was thinking it could be possible that the timing chain on the rear of the head broke? i wasn't there and didn't see it thorn apart. the noise came from the top rear of the head. i was looking into thats back there online maybe the plastic chain adjuster broke on start up?
Any help on this would be nice I am very mad I paid for a ex-warranty that lasted 35,000 miles for a extra 5,500.00 3 years ago. I still have 2 years to pay for this car.I thought the warranty was for the life of the loan for 5 years or 100k miles that i put on.

Vacuum pump is driven directly off the intake cam. But usually a seized cam is obvious damage at the journals affected and stops, or sometimes breaks.


If the cam seized it had lack of pressure, or ran low on oil. Are you doing the 10,000 miles wait for the dash oil changes. Unfortunately in my experience thats whats killing these engines, because most people go a few thousand over what the dash says, which is 10k+ miles. The oil becomes grit, and is hardened into coke from the turbo. I have seen the chain tensioners fill full of grit and stop tensioning and throw the chain off, bending valves. If you have the engine replaced, keep to 5-6k oil changes, full synthetic 5w40.
