Timing chain in the usual good OEM quality.

The timing chain as well as the timing chain tensioner should be checked every 10.000km. Sloppiness here can have expensive consequences, as lifting the timing chain off one of the sprockets will cause the chain to jump. In the best case the engine simply stops, in the worst case the valves collide with the piston and a capital engine damage occurs.

A simple check to be carried out at the specified interval looks like removing the spring for the timing chain tensioner and then the chain tensioner itself. When pulling out the tensioner pin, a clack can be heard. If it clicks 4-6 times, everything is okay. If it clicks only 2-3 times, there is clearly wear and the chain should be replaced.AI-translation
