I'll prepare this guide as a series of steps. That way I will eventually get the guide completed.
Step 1.
Have some idea of what you want to achieve and how you will achieve it. So the first thing to do is get hold of a manual and study it. The one I have cost me just £10 and sits on the hard drive of my PC.
There are various options and kits available for this repair, from just the tensioner / tensioning rail, tensioner / tensioning rail plus a chain, all the components except the interference fit crank sprocket or finally all components. I bought all components from Febi, these are genuine Audi / VW components with the branding removed:
The sprockets and chain from my car were in very good condition showing only slight signs of wear:
The tensioner and tensioning rail were however worn to what I think was the brink of failure. The pads that the chain runs over were almost completely worn through the tough surface material and the softer core material was breaking up:
I think failure of my engine was not far away and this would have been caused by the tensioner and tenioning pads failing causing the chain to fail. I believe I could replaced just the tensioner and tensioning rail. Your decision but read this thread first as I will point out all the issues not covered in the manual.
Now is also the time to check your service history and consider:
New timing belt
New water pump
New auxiliary belt
New auxiliary belt tensioner
