Well had the engine management light come on now and again so decided to lift the bonnet to find.....................
The Swirl flap bar had come off. Mine car had just been made before the uprated version was introduced.
So its at a friends garage having the following done:
Replacment Manifold and flap motor.
Water Pump replaced
New gasket/o ring for the Vacumn Pump as its leaking a bit of oil.
All being done for less than the dealer charges for replacing the Manifold.
Should see me through for a few more K until the DMF needs replaced..........
