[2fast2furious]

my merc 200e is idlen at 1500 rpm and ive checked all air hoses etc for leaks n they all seam fine, slakend off throttle n tightend n adjusted tickover, i get it down to 750 but but it resets its self back to normal cos its electronic , is the only way gonna be taking it to garage and getting it put on the diagnostics or any1 know other ways of sorting it out.?

Even diagnostics aren`t 100% it lists posabilities. Obviously it should be around 1000 - 1100 rpm, have you checked the air flow?

EDIT.

Just seen that you have, so don`t know.

Good luck getting it fixed.

im starting to think its the MAF sensor because it started to limit at 4000 rpm so i took sensor out and cleaned it slightly and put back in and its limiting properly now but still idles high, ive had it on diag but says nothing wrong with it, dont really wanna take it to mercedes as they will charge a fortune haha.

check your throttle body + throttle cable.

If you have a problem with a Merc, take it to Merc. Any work carried out on a Mercedes which goes wrong is not covered unless the work is carried out by Mercedes themselves, this is a fact.

Go to a forum that specializes in cars you'd be targeting a wider range of people that know all that kin of stuff about cars.

Take it to Mercedes, only way you can get the guaranteed work needed.
