C280/c36 not revving fully.

[paterson12]

Hello,

I have a c36 amg that I have been doing up. I believe the c36 is roughly the same engine as the 280. Car runs great with smooth gear changers, but under hard acceleration it only revs to 5200 rpm 1st gear, 6000 rpm 2nd gear, it never revs to the red line (7000rpm).

Is this normal?? If not then what could it be??
I'm not overly bothered as I never like taking a car to the red line but it's nice to know everything is working how it should.
Any ideas would be great

Cheers

Change the fuel filter, cheap, easy and good preventive maintenance regardless.

Thanks for that John. Already ordered and ready to fit.

Faulty MAF. You will be guessing and spending money without a star test.

I thought it could be a faulty MAF although the car runs well general. I might unplug it and see if it runs better, if that works?
