Hi all,

I've just bought a 2012 C63 Estate and I absolutely love it. I took it for a drive this evening, and spent about 20 minutes or so driving it quite hard. The oil temp sat around 111, and the water at 92 (celsius), which I've heard is normal. However the cooling fans seemed to be absolutely howling (I had a Lexus RC F before), and there's an electrical type-buzzing noise whilst they run. Is this normal? If not, what could be causing it?

Thanks in advance.

 

Not really normal hard to tell without video - really you need to pull the codes and see if there is anything showing a fault, good info in this thread https://mbworld.org/forums/c63-amg-w...re-ok-why.html

 

It is common for the fan to be howling after some spirited driving. I'm not sure what you mean by the electrical buzzing noise.

 

Thanks for the advice! All seems to be well!
