I think it's 7nm.

The torque specs are in your DIY 82mm TB thread. It’s NOT gorilla tight. 12nm? They’re all the same and strip easily.

It's either 7 or 9....defo not double figures though.

Yeah man they strip super easy....that's why I had to source a replacement intake manifold at one point.

Anyone ever hear of the plastic booster fitting leaking ? or know if it is serviceable ? I had the P0171 and P2187 lean codes. Local MB dealer hooked up the smoke machine and said the leak is in the fitting for the booster line itself, not the fitting on the hose side. There is no replacement or repair to their knowledge and the entire IM needs to be replaced (they say). Thoughts ??

It can happen.

Try wrapping one layer or two layers of masking/duct tape around the portion of the booster line before slotting it in.

Too much tape and it'll kink badly and not seal. Not enough and it'll still leak.

Question for everyone. Iíve noticed after performing the valve cover gaskets I still had a leak. Then I read somewhere that thereís a bulletin where Mercedes recommends adding their own gasket sealant to some points on the valve covers. Thatís fine but my question is will I need that same sealant when doing the intake manifold gaskets? Iím heading some people are having trouble pulling the manifold off and finding sealant residue.

you donít have to pull the valve covers off to do this job. And pulling the intake mani off would not show you where sealant would be. That being said, Iíve never heard of this. Iíve only heard of leaking from failed or improperly installed valve cover gaskets.

I just ordered a replacement pipe from Germany via my local dealer today as mine is leaking at the white plastic fitting that goes into the intake manifold, above the IAT sensor.

It might be a slightly different part number to the W204, as it starts with A212, but i'll take pics and post the part # when it arrives next week.

Ok, so new pipe arrived a couple of days ago....I've given it several drives over two days and LTFTs are ~+7-8% bank 1 and ~-1.5% on bank 2.... CEL hasn't come back and I hope it doesn't. No stumble or wobbly idle that you sometimes get with a vacuum leak...power delivery feels smooth and strong...vacuum with throttle closed at 12.9 degrees opening is around -19.5 ....fingers crossed, this might well have solved my issue. If the CEL comes back, I'll let you know it failed. However it has definitely helped. Previously, the CEL was coming back within an evening and running the car rich. It's running nice and stoichy at idle, rather than 13.2:1AFR. For what it's worth, the pipe had a nice firm click that you'd expect from fresh tight plastic when I connected it to the brake booster. It felt tight and taught when inserting it into the intake manifold port also.


New and old...yes, the new one looks a tad smaller....either that or less stretched from the heat of the engine bay after 97k miles




Part number comparison




Worn old vs new


CEL pending, it's time to put this car for sale and get out of the AMG game for good

If anyone needs pm me. Twenty for one, only two available. Repairing with a sleeve woulda worked but it just didn't feel right so I bought a used sprinter manifold (80$).
