Again. I'm curious where Stephen taps in to introduce the cleaner.
for those that have a dirty throttle body, I would spray via the port designated with an orange arrow in the attached image. As you have to remove the sensor temporarily, this will throw codes so you'll have to clear them after you're done spraying Liqui Moly or BG245 or whatever else that may work.
I should add that this is an image of 2007 W211 OM642. Your setup may be different.

Is this the same spot? Please see attached pic.
Its a EGR temp sensor part # A0071538128
That looks like an excellent spot! That must be the access point Mr. Stephen is referring to. This places the nozzle at the point where the left and the right intake manifolds will get exposed to the cleaning solution.
My 2007 w211 Om642 does not have that sensor. Looking at my setup, best way is to remove the "muffler" which is located just above the throttle body and run the nozzle just before the 2 manifold openings.
Had some conversation with people who worked on Audi's a BMW diesels. Their opinion on using spray is hell NO.
All that buildup will go through the engine, it might made very big damage.
The right way is to take thar pipe and replace with new. Pipe is about $40.
I personally am not concerned about this "soft" sludge affecting metal interior parts. I'm more concerned with DPF so I'm thinking of perhaps temporarily disconnecting exhaust during Liqui Moly application.
I had a tune downloaded which deactivated the EGR among other things. I had the DPF eliminated and the DEF deactivated. Hopefully I'll have relative dependability and no worries about EGR blockage etc,

Looks like MB came out with a bulletin advising service to clean the short Egr pipe(front of the engine refered to as egr admission hose) every 40k miles. What I'm looking for is a way to tap into the intake system of a running engine (so without taking it apart) that I could spray in the cleaner at a pressure which would end up as a nice gush of a mist.
Has any one done it? What's the ideal spot to tap in? Ideally I'd like to get rid of the EGR system as I see it as the main culprit of diesel engine problems but for now, I'll remove the egr admission pipe and clean it following with a spray of the cleaner.
Does the MB bulletin specific engines and years? I have a 2008 3.0 OM642 v-6 and occasionally receive check engine errors that reference EGR. However, I don’t have any typical bad EGR symptoms.

Can you share the tune? Or where to get it. Also how to apply the update. I have a 2011 om642 W212.
Green Diesel Engineering (GDE), was. They were out of Michigan I think.
I contacted Keith the year before the stuff hit the fan, but I didn't pull the trigger.
Malone is out of Vancouver BC area, still around I guess is a jurisdictional thing.
@GoodByeHonda Could you send the part numbers for the gaskets that you'll need to manually clean this pipe? It'd be much appreciated, thanks.
Also, from what I'm understanding, it's just 3 bolts on the one side to remove the pipe from the engine?
I just removed this pipe on my 2009 E320 Bluetec. To confirm, yes, only 3 bolts on the throttle body side to loosen the whole pipe. It then has a compression fitting over the o-ring on the other side, no bolt. The parts numbers listed worked for my E-320. The o-ring on the inlet side of the pipe took me an hour fiddling with different picks to get off. Otherwise the job is pretty easy.
