I have a small prob with my C250.
I have a loss of power, only a slight loss, its like driving the car without the superchip that i had fitted. The car has been excellent since the superchip was fitted a few months ago, a real pleasure to drive!
Since this morning, its felt sluggish. I made a detour to GF this afternoon and placed the car on diagnostics. The only fault code was a minor one, something to do with the air pressure. I made a trip to MB stratford and picked a new MAP (manifild absolute pressure sensor). I read previously that Jimmy had similar probs and it was this unit so i changed it.
At this point i should mention that i fitted a K&N air filter day before yesterday I know it harms MAS sensors etc, BUT mine doesn't have one as after the air box the pipe goes straight intthe turbo. Maybe completely unrelated but even so when i fitted the new sensor i changed the filter back to the old one.
Any the prob is still there, its still slightly sluggish. I had presumed that maybe the superchip had gone wrong, but after a call to them they assured me as the chip was changed the car couldn't revert back to its old settings! They have offered to check it but are 100% the problem lies elsewhere. They stated that they get alot of queries like mine and 99% are faulty MAS sensors, nut mine doesn't have one!
The turbo definately kicks in, and definately doesn't feel like a pipe's come loose, as it normally blows off completely!
Any ideas as what could be wrong? I'll probably change the diesel filters next but am not entirely convinced its the prob!
