My C280 (V6) is having a bad month! Just fixed my aircon blower and now I am getting a metallic clattering sound from the engine at idle.
It goes away as soon as any revs applied and then the engine seems smooth and quiet as ever. I have tried to hear where it is coming from but it could be anywhere - although seems to be at the top end perhaps? It seems to have got louder in last few days but I could be being paranoid. Sounds horribly expensive though I hope someone has an easy (i.e. cheap!) explanation!!
Could it be timing chain tensioner? Don't know why this occurs to me but it's just a thought...does it even have a timing chain tensioner or am I making it up?
Desperate for someone who knows more than me to give me a steer in the right direction.
Thanks
