Anyone ever cleaned out the EGR/intake pipe?

[MrGreedy]

I have a 2010 E350 CDI W207. So it should be the same engine.
I cleaned the mixing duct last week when I replaced the intake swirl flap actuator and the oil cooler seals.
It was quite dirty even with EGR delete by map.

Hi Tommy
I would have a guess that if you have an EGR delete, but it's still getting dirty, then the EGR valve isn't seating correctly and remains open a tiny fraction. A blanking plate might be an option to solve this (not usually necessary with a part that operates correctly i.e. remains closed).

If you have iCarsoft or similar, you might be able to interrogate to see if it is recording a position error.

Hi Ed,

I have a 2010 E350 CDI W207. So it should be the same engine.
I cleaned the mixing duct last week when I replaced the intake swirl flap actuator and the oil cooler seals.
It was quite dirty even with EGR delete by map.

See attached pre & post pictures of the pipe which sits inside the mixing duct.
The bad picture of the mixing duct is during cleaning process. The pile of dirt is just a bit of what I got out from the duct.

Just give me a shout if there´s anything I can help you with.

Cheers
Tommy

Managed to get the plastic shield with the 2 bolts highlighted earlier off - it is just two bolts, there isn't another below, it's just kind of 'hooked in'.

Hello, To get the plastic shield off - Is it just a matter of pulling upwards after the two top bolts are out?
Would really appreciate any advice on this.

Essentially, yes!

The bottom is kept in via a rubber 'bung' that positions it, and then the top two bolts secure it in place.

Thank you very much for a quick response,
I guess then it's just a matter of applying more force and will power
