this car has gone 320,000km's so about 200,000 miles, and when the engine was warm, at idle there was some noise from the chain. One my friend has similar car but lower kilometers with 400cdi engine, and there was the same noise, so he chanced the chain and his chain has streched almous 50mm!!
So I think that it will be better also to chance the chain.
The chain has now been chanced and the result is:
the chain hasn't strecht almoust nothing, sliding rails was good gondition, but the biggest broblem was that the chain thensioner was broken. At same i also chanced the belt, guide wheel and tensioner. Generator wasn't good gondition (sliding rings was very worn and and carbons was almous end) but just now i havn't new but because it is quite easy to chance it has to been chanced later.
I also opened the oilpan and looked inside the engine. Sylinder inside surface looks like new, there wasn't nothing visible mark of wearing.
