What should I do to tighten my timing chain?
Tighten the chain according to your car manual’s specifications. Some chains are tensioned by adjusting either the crankshaft gear or the camshaft gear, while others have an automatic tensioner.

This is much more cost effective than returning for the same service after a partial service interval has elapsed.
What happens when the timing chain is loose on an Audi?
Tensioners make sure the chain is tightly wound to the pulleys and gears. If the tensioner fails and the chain becomes loose, the timing of the engine is thrown off. When a timing chain is loose you’ll likely hear a rattle during startup or idling in the engine.
What happens if your timing chain is out of sync?
