Hi All
My father in law asked me to listen to a strange sound coming from his 2004 CLK200 at the weekend, but when he started the car, I couldn't hear anything wrong - After I left, he sent me these videos (the noise developed after the car was warmed up) - Before I go back, does anyone recognise what the cause of this sound could be?
Cheers

Whats the oil level like.

I had a look at the belt and pulleys while it was running and they seemed fine - (But at that point this sound was not eminating from the engine, so I just suspected it could the tensioner bearing as a guess) - I need to have another listen to it when it is warmed up and making this noise (no idea about the oil levels, but probably they are ok as i'd imaging a warning light would function if too low - I will ask the father in law to check)
