W204 220 Cdi throttle body location...

[monkeyboy]

Can anyone tell me where the throttle body is on a 2009 c220 Cdi (651 engine?)

Also, is there a way to test it? Have been getting a Charge Movement Flaps Bank 1 code which I've been told is the Throttle Body...

Would be nice to test before weighing out for a new one..

Diesels don't have throttles, they flow full air all the time. The 'charge movement flaps' are more commonly known as swirl flaps, their function is to cause turbulence of the intake charge at low engine speeds. They are prone to sticking and jamming, especially if the car is primarily used for short journeys.

They're located in the intake manifold.

The modern diesels do have a throttle flap. But it does sound like an inlet port shut off motor issue.
