Hello,
I have a 2007 model ML350. my car started giving a P2004 fault a while ago (I always check with muscat/ithink). When you look at this fault on the internet, everyone says that the intake manifold rod is broken and must be replaced with aluminum. however, when I check it with my eyes, it seems that the middle piece is not broken, and when I move it with my hand, it also moves. What could be the reason? My car has a lot of oil leaks, I cleaned those parts, but the problem still persists. Where can I check? Can it be a sensor error? Where is the sensor?

I have attached the video below. ( while searching for the problem, I saw that the map sensor was broken and I bought a new one, the problem is not solved)

(i delete fault codes, its cleared, then i do some revs 4000rpm etc, fault code appears again.)

is there any xentry function for test?

is something look weird?













because of working alone, I couldn't see if it was working while testing.

 

Hello again,

I went to another repair shop recently, I said there is no broken part, but there is the error code P2004, they looked and said that the part on the right seems to be broken. I said ok, I asked for the repair kit, price etc. They said we don't repair it, we replace it completely. (I decided to have it done later as it was an expensive procedure.)

Anyway, I was driving the car like this for 4 months, I cleaned those areas with "carb cleaner" on the weekend and wanted to see the broken part myself, and bingo yes, the broken part was there.

but there was a problem! it wasn't part of the manifold.

For a long time the engine top cover was not sitting in place and its teeth were broken and I thought it might be that part.

I pulled the part, got it and yes the P2004 error is gone and now the manifold works just fine.
