Read this on another site - worth a look!

There is a TSB on the motors, apparently they fail. VW apparently put a flap in the intake manifold that opens and closes to increase and decrease airflow to the cylinders. 

If yours doesn't work, you get a code that says intake manifold runner control flap stuck open. You will notice two things with your car. 

1. A loss of power. Not huge, but instead of your car accelerating quickly it accelerates slower and just gets louder. 
2. At idle, the car does not have a steady idle, it goes up and down. Again, this is not severe, just not a smooth idle. Fluctuates 100 rpm or so, nothing major. 

If the  motor is fine, the problem could be - that there is a control arm that presses on two plastic pieces to open and close the flaps

Thanks... mine does both of these... the idle is often pretty lumpy and then sometimes the car makes more noise but doesnt get proportionally faster .

I've booked it into the garage and given them the fault codes and told them to look in this area for the issue.

Ok been away and busy so only just had chance to follow this up.

Its been in to my local place who has VW looking into it but he says it may need either a new motor or new manifold!? Neither of which sounds cheap.

Anyone have any more info on this issue.

Anyone know how to get hold of VW TSBs? Apparently there is one out for the manifold flap motor.

Does a TSB mean as its a known issue then its done FOC? Or is that wishful thinking :)

Just to conclude this... I had the manifold flap adjuster motor replaced and it seems to have fixed the running issue.
