Intake Manifold Flap Changeover

[Nick125tsi]

I was wondering if had any experience with the Intake Manifold Flap Changeover. It is the assembly at item 4 in the attached diagram.

Where this connects to the shaft on the intake manifold (the actual shaft at the bottom of the actuator rod) had pushed out from the intake manifold and allowed an air leak. This caused a very rough idle.

I was able to re-seat the cover (connector) to the Intake Manifold Flap Changeover (a good firm push with a finger) and this has corrected the problem for now - however has anybody seen this happen before?

It is as if there has been end float in the manifold flap butterfly assembly that has dislodged the actuator from the intake manifold than now allows an air leak at the seal of the intake manifold to actuator rod point.

You most likely need a new intake manifold.

Unfortunately it's a known problem with the TSI engines. The fix is a new manifold.

They are a lot cheaper from the UK but you need to ensure you have the correct partno.

Clean the inlet valves, etc when you have the manifold off.

Thanks guys - I suspected it might be an intake manifold - but I was hoping there might have been a simpler fix.

IE will soon be releasing an alloy manifold .
There is a group buy currently underway if youre interested .
They arent cheap but the gains are impressive .

Would that be with flapper delete or still with flappers?

Flappers are nice for low down torque aren't they?

Thanks for the info - however it is my wife car - she does not need to go any faster
