W204 Throttle valve leak

[potterwoz]

Afternoon all.

Bit of a follow up to a thread on the suspension section but I've recently been under my car a lot.

I've found what seems to be an oil leak from the (charge) air pipe into the bottom of the throttle valve.
Has anybody had such issues before? Maybe a seal has gone on the valve? I've had a look for part numbers for seals etc but can't find them ****** anywhere!

I'm also hoping it's not a turbo seal or my turbo on its way out as nobody wants that no loss of performance etc. Just something I noticed the other day.
Thanks for any info

Is it a metal pipe or a hose

The oil is running down this pipe from under the throttle valve!

Hi there.

Just updating for those who may have the same problem (always helpful).

Had the car fault codes read and it’s thrown up P200A75 - The charge movement flap (cylinder bank 1) has a malfunction. The emergency position was not reached.: stored.

I imagine this is due to the build up of soot and carbon over the 94k I’ve done in the car so I plan on removing the EGR, Throttle valve and intake manifold to give it all a good clean.

The Indy has said however that removing the intake manifold and throttle body is dangerous as if I move the flaps they will lose the position memory and it has to be sent to dealer to calibrate them. Is anybody aware of this.?

Thanks in advance
