HELP! MAP sensor..

can anyone please tell me where's the MAP sensor's locate in C32? and whats the parts number for it?

my problem: car's running fast like a Rocket, but sometimes it doesnt... even slower then a C280 W204.. so... that might be the problem according to the THREAD https://mbworld.org/forums/showthrea...&highlight=map

I've got my I/C pump just few days ago, the problem still occur.. so MAP might be the problem. S/C clutch are working and the gap is 0.38 now. so that's should be fine..


many thx!

Pull the intake and the right surge tank and you should see it... Look at post #18.

Boost too high should be P0108. Is that what you are getting?

According to his mods guys, the problem would be a combo of his custom 190mm pulley maxing out the MAP sensor, along with no HE to cool the high IAT's.

I think your pulley is too large.....

1) Lower your IAT's
2) Get tuned
3) Get used to the CEL triggered by the P0108.

Your ECU is going to be like W.T.F. with that kind of boost. It doesn't seem to affect performance though.

That also seems like a big plug gap for that boost.
