Hey - I just changed out the timing belt (and tensioners, water pump, thermostat, and accessory belt using the ECS Tuning kit). the car is a 2007 A4 B7 with the 2.0l. During the installation I had to do a lot of fiddling to get the timing marks to line up - although I lined them up prior to tear down, they did not line up after the belt change. I ended up taking the belt back off and reinstalling the lower cover and pulley and lined everything back up. Not ideal, I know.

As I worked on it I moved the cam pulley just one tooth on either side of the timing mark - that shouldn't be a problem. On the other hand, I rotated the crank pulley full rotations several times and that has me thinking.

I have it to the point I could start it. I have cranked the engine by hand several full rotations with a screwdriver in the number one cylinder and get TDC with my timing marks aligned. It doesn't take any undue force to turn the crank. So, I think I'm good but was wondering if anyone had thoughts on any potentially non-destructive testing.

Thanks!

Update - yep, I did it right. Started on the first pull (Audis are supposed to have pull start, right?) and ran beautifully.

In the ecs instructions it mentions you may have to turn the cam a tooth back because once you turn tensioner it advances a little bit.

That's exactly how I did mine and after turning by hand 2 rotations the timing marks fell perfectly everytime.
