Thanks for the informative reading so far and for that hoped in the future.
To the problem(s). My C220 CDI(2001) 80K miles recently developed the safe mode symptom when warm, was ok when cold. I have noticed a little black oil from the inside of the front skirt o/s. With developing education I believe this is possibly from the turbo, at the intercooler connection? The engine oil is very fresh, the leaking oil black possibly because of the turbo temperature??
The car has enough power to pull away smoothly, in fact drives smoothly. Acceleration is abismal, economy is reduced. After reading threads I replaced the Air Mass Sensor, problem not rectified. It least I have the recomended spare now.
I got the missus to rev the engine (she with eyes closed and wanting to wear a crash hat) while I checked around the whirly bits. At 4K revs the waste gate shows no response (I assume it should be at least starting to open, its free to move when engine stopped). At these revs what feels like good pressure can be felt from the air duct diconnected at the intake manifold
On forum recomendation the slug is booked in at the specialist but this is 2 weeks away. Any pointers would be appreciated. Thanks in hope and anticipation.
