C207 intake woes

[Carrotchomper]

Folks,

I’ve had slight issues with my ‘09 e350CDi coupe. Slight hesitation in the midrange, generally fine on full throttle but part throttle makes it flutter/misfire a bit. Had it into Indy yesterday and they stated “Turbo inlet pipe loose and air box missing 1 bolt. Advise renewing inlet pipe and inspecting seal and plastic joint”.

Fine thought I, pipe will not be much...

WRONG! £700 ish! surely there’s some other way to buy individual seals rather than the whole unit including 2 air mass sensors?!

I don’t want to blindly replace this... where do they tend to fail? I have seen the seals which attach to turbo separately. Is this just a 5min job that the garage didn’t do since it’s not part of the service? (And no críticism of that!)

went into limp mode on the way back from the garage, first time it’s done that but thankfully a restart sorted it!

Be worth contacting a mb dealer and if the parts guys are on the ball they might find the seals separate. Or try searching here with your vin. parts catalog Car mercedes CHASSIS EUROPA, original catalog Car mercedes CHASSIS EUROPA, online catalog Car mercedes CHASSIS EUROPA, Car catalog Car mercedes CHASSIS EUROPA

Had a look and these seals are available separately. Both ends, main seal and breather seal.

You’re an absolute stair, thanks so much. Even for Merc it did seem bonkers that you could only buy the house sized bit of plastic and MAFs x2!

I’ll have a good look and clean up of the air boxes and hose assembly to see what’s what. Air leaks are annoying, only takes something tiny to knock the engine out of kilter!

I wish I was a stair.
