Just bought a E320 CDI 2000 very slow performance, Took off turbo at weekend and checked wastgate and vacume lines. Turbo (garrett) looks fine and wategate & actuator works OK.

Air Mass meter has been replaced by the garage in UK, car is now in Ireland.
Had the codes read in another garage here and there was a code for the air mass meter and intake or inlet valve???? got the guy to clear the codes and went for a drive (still no power) came back and read the codes again now only showing intake or inlet valve???? code. Any ideas anybody...Have car booked in with this garage in two weeks time...

Not many CDI owners, especially from across the pond, on this board. I hope someone chimes in, that you can get your problem solved. Have you tried unplugging the MAF to see how it runs in default mode?

No power difference with the MAF un plugged .... reading from other sites its like it's in a limp home mode ....kickdown dose not work either..... waste gate on turbo cycles on cold startup but dose not move after that can't hear turbo, will spin up if I manually force the waste gate shut and rev engine, had turbo and waste gate apart looks fine.... The only code that came back after the codes were cleared was to do with the inlet port shut off motor, this was a bit stiff had it off today and freed it up, it moves very slightly once or twice then no more movement ...... Many thanks for any help.....
