kestas-

let me r give you more info...

The diagnosis I gave was after my car was hooked up to the MB diagnostic machine.

I was told by MB that the codes came back clear (for two valves mentioned earlier). They said when the issue is the wiring harness the error codes or information they get back from the diagnostic machine is much less clear???

I do not know if i should be happy it's not the wire harness or be very scared because I am at the bigging of a journey that will cost $$$ and ultimately lead to them telling me that if fact i do need to replace wiring harness?

I asked for the error codes to be listed. I guess I can check them against info from the forum?
