Could this be an EGR issue?

Iv recently bought a 57 plate very tidy CLK 320 Cdi Sport with 86k miles. Under light acceleration there is a misfire/stutter but this goes when you push down harder on the accelerator. The car pulls hard through the gears. It's more noticeable in C mode than S.

For example driving around a car park you notice a stutter. Does it sound like the EGR needs attention? Mine doesn't have a DPF either..

Have you had a look for any codes (or pending codes) on the ECU?

Its booked in at the garage I bought it from next week. Drives great when you open it up. Does it sound EGR related?

more likely to be a maf problem,try unpluging the maf to see if it runs better

This would never work on a V6 cdi
Just put it straight into limp mode

Would this show up on the diagnostics?

Will show left or right, depend on where the problem is
My problem was on the left...
Have a good look at the oil brether as well, I think is what cause my problem, I change that one to.

Update. When the car is upto temperature and it's given some beans on dual carriageways etc the stutter at low speeds disappears even in C mode.

But the problem is evident when the car is getting upto temperature in stop/start traffic. Any ideas?
