Audi A6 3.2 Timing Chain Tensioner Failure Cause

The Audi A6 3.2L Timing chain tensioners can fail and it will make a growling noise when you start it cold or you will get a check engine light with a camshaft corrolation fault.

There is a little plastic rubbing block or guide that the timing chain rides on and from a combination of age and low oil the rubbing block can crack and fall apart.  This causes the timing chain to ride on the metal part of the tensioner.

I have seen shops just replace the tensioner beacuse it can be done with the engine in the car.  This is often a mistake because by this point the chain is stretched and when the first try to start the car with the new tensioner because of the excess slack in the timing chain the valves get bent causing several thousands of extra repair costs and possible machine shop work.

If you have questions need parts visit us at www.DoylestownAutoShop.com

You can send us your engine and we can replace the chains or rebuild it if necessary.

 If you have bent valves and the guides are damaged Audi does no sell valve guides but we have custom guides that we had manufactured for us and can install them in your cylinder head.
