Welcome to the forum.

You really need to get the car scanned for fault codes by someone with the Star /Xentry system. It could be many things causing it, Turbo actuator, sticking variable vanes, a sensor issue etc. Has the car got a good service history?

Also, what is the mileage?

I see that you have posted the same question twice?

Hi yeah sorry I'm new to this forum stuff lol car has a really good service history all mercedes dealership with receipts all adding up to 10k for parts and stuff for the car it has only covered 127000 Miles wich I thought was reasonable for it's age but I will try find a garage that will be able to do the scan on it and see if I can get the issue fixed thanks

Was it a private sale or from a Dealer? If from Dealer then take it back.

I would strongly recommend finding a Mercedes specialist. They are good engines so hopefully it will be an easy fix for you.
I assume that the EML isn't on? You could check that the hoses to and from the intercooler are OK with no splits or damage to them

I had a similar problem with this engine in an E Class which was an actuator.

Let us know how you get on

Hopefully it will be turbo actuator , exhaust back pressure sensor or swirl flap motor (inlet port motor) .
If you are unlucky it might be the turbo itself .
But as above get it scanned .
You could buy an icarsoft MB2 for £100 if you plan on doing work yourself .
I’m guessing these car faults are why the car was sold ?
