A lot of times you can visually inspect the bolts securing the timing covers and see if the paint on them has been chipped / worn off. Aside from that, there's really no way of knowing if it's been done if indeed it was done correctly and everything was put back together correctly.

 

Sometimes a mechanic puts a decal underhood with the date and mileage of the change. Absent that, call a dealer with your VIN. If it was done at a dealer they should be able to retrieve the information.

 

If you can't PROVE that it has been done, do it. Have it changed yesterday. Don't drive it, have it towed to have it done.

By the way, are there instructions around on how to do it on a 1.8t, 2003 model?

Very nice! Thanks! I learned how to do a timing belt job on a Volvo 850 from that site.

Sad to see that the front bumper has to come off but whatever it takes I guess.

Is there a Head Gasket tutorial for this A4 somewhere? The head gasket is blown.

 

What does the stealer usually charge for that timing belt/water pump job? Looks extensive.

 

Ahhh, found the head removal thread. Thanks again for the list.

 

No worries. I was quoted $1000 to do the TB from the Audi dealer by me. Probably varies though and I'm not sure if that included the water pump. I've just always ordered the kits from blauparts and did the job myself for around $450 for everything. Takes me between 4 and 6 hours to do the TB taking my sweet *** time drinking cervezas...I've had help before and did one in just under 4 hours on a B5 1.8T. Head gasket should be quick and pretty straight forward as long as nothing got too hot.
