Engine Mechanical problem
1999 Audi A4 6 cyl All Wheel Drive Manual 135000 miles

My son bought a 1999 Audi and took it to a repair shop to have the oil and transmission fluid replaced. They took him it need a new sirpentine belt and cam seals replaced, At the end of the day, they called and said "they replaced the seal and when to start it up .. it would not start .. they checked the cylinders and there was no pressure. They investgated more and said the timing has jumped about 5 teeth foward, because a belt tensioner had failed.. now they replaced these parts and still no pressure in the cylinders. Expection is that the valves are bend now .. They are say 1500.00... My thinking is that they screwed this up when replacing the seals...

The car ran perfect before they started working on it ...

If the car was running ok when it went in for the oil change, I tend to agree with you! Timing belt needs to come off to replace the cam seals, and they may have screwed up something...
