Timing belt OEM Audi or Contitech

I have personally been running this one for the past 3 years with no problems. As for the belt itself, I always run a conti tech (OES) belt and never have had a issue

An old Audi belt motor goes 240k and the belt is still holding. I had a 2013 A4 2.0 that stretched the ~~belt~~ chain* at 70k and the valves kissed the pistons.

My last car was an A4 with AMB engine and the recommended timing belt change interval according to maintenance booklet was at 110K, while at the local dealer they were trying to persuade everyone to change it at 80K. I did one myself at 104K and it was just the right time as I noticed it started to stretch.

I changed my timing belt a month ago and my car had 111250Km and ten years young. First of all, I was amazed by the quality of the old timing belt, it was solid with no cracks at all.

If so, I had the same issue with until I did my first belt change at 100k miles. I thought it was the tensioner, but turned out to be the writing on the back of the timing belt as it passed over the tensioner roller. After I did the belt and tensioner and rollers, etc., the swish, swish, swish sound never came back. FYI, went with a Conti-tech belt rather than VW.

There is no way to know without removing the cylinder head and posting pictures. Best case you can just replace the timing belt and any bent valves.

As an alternative to a chain drive, timing belts also markedly reduce CO2 emissions. ContiTech developed the CONTI® OIL RUNNER™, which runs like a chain in oil and holds out for the entire life of an engine.

6 years or 75,000 miles is the most I'd push any timing belt. We inspected a timing belt on a 2002 A4 with 57,000 miles in September - in-service date of 6/1/02 so it's over 6 years. Told her the belt is walking off, riding the edge of the tensioner and fraying.

I changed with new belt but it is also a half tooth. It always lines up with cam cover arrow just at the line at the end of the tooth rather than middle of it at tdc.

The tab that the cam gear has to spin the cam, snapped off the gear. Even though it was in time, the gear just spun on cam and didn't spin the actual cam.
