320D 184hp short interruptions constant acceleration

Hello. I have a 320d 2011 184hp and sometimes when I drive constant let's say between 1800 and 2800rpm i get some random stuttering for a fraction of a second. What could it be? I am thinking to change the 2 pressure convertors ( part number 7810831 )

Mileage?

Would suggest having the intake walnut blasted first, before changing things.

The car has 200.000 km.
I don't know if it is just an impression but it does not feel like it has the same power under 2000rpm as it had before.

I have a similar sounding issue on my 330d. The o-ring for the intercooler pipe going into the intake manifold has split. I will be replacing it in a couple of days so will let you know if that fixes it. Might be something worth looking at.

Very easy to take off and inspect so worth a try before spending big money. Mine is on 130,000 miles.

Cleaning out intake manifold is a shout too as mentioned. Makes a considerable difference and cleaning the throttle while it's off is good too.

EGR can also give these symptoms, easy to check if it's excessively dirty by pulling off the intake pipe from the turbo.

Seems to have fixed the issue for me after a quick test drive. Was like a tenner from local dealer. Have a quick check of the intercooler pipes I reckon. At least then you can eliminate it if yours is fine
