Will not rev above 2500-3000rpm and will not kick down

My E320cdi s211 will not Rev above 2500-3000rom and not kick down! It runs fine other than that. This is also intermittent. Does anyone know what could be the issue? Thanks

When I had this exact problem with my S203 C270Cdi it was the MAF, replaced it and all was well.

Whilst the MAF is a likely culprit it is not always the cause

Thanks I hope it is he maf and I'll get it checked next week

if your a member of AA or RAC they could run a diag for you to confirm...as its free

I am a member of AAsoi could diagnose it but is there equipment Star compatible?

^ The AA will use a generic code reader that should indicate if your MAF is knackered with its own fault code.

Thanks I might ring them next week for a diagnosis! Hopefully it will be the Maf sensor
