We have 2003 c230 with 71000 miles on it.
I've noticed there is oil and dust residual near crank position sensor, infront of the engine where black plastic hose goes into the engine.
I've cleaned this area about 3 weeks ago and I've noticed slow build up of oil and dust.
Is there oil leak from somewhere that causing this problem?
Anybody had similar problem before?
Any info would be appreciated.
Thanks.
