230 Slk Kompressor Not Working

[awg454]

After fixing the roof problem with my wifes slk i had a quick drive in it, not somthing i do that often,it felt really sluggish at anything over 2000rpm,the krompressor is not cutting in,i have today replaced the Air Recirculation Flap,which was not shutting off as it was surposed to do,but it still doesnt work!also i have tried both cam sensors as these came up as faulty but still it doesnt work,it also says the electro magnatic cluch is faulty but if you power it up direct it triggers and the supercharger runs ok.
even with the new parts fitted it still throws up the same fault codes!!
i am now probaly thinking it could be the main ecu as mentioned in other posts on here,anyone got any other ideas/tips
Thanks
Peter

It probably is the ecu which has shorted due to the air flap motor wearing out and shorting.
It will be the output driver chips. BBAreman can fix this I believe.

Sounds like its still in limp mode.
Give the MAF a clean with carbt cleaner. Also repmeve NEG battery lead for an hour to reset all codes and stored faults.
