Hi.
I have two problems, I have a 2001 C220 CDI.
The first problem is the Auxillary belt makes an awfull noise on idle as if it is too loose.
I have fitted a new tensioner & belt, but still have the same noise.

The second problem is when the car gets to quarter of a tank of fuel & i park it on an incline it runs out of fuel & i have to put it on level ground & bleed out the fuel system.

Any ideas?

Thanks in advance.
Barry.
