Hello everyone!

Right long story short... been having hesitation and jerkyness for the last couple of weeks. Had a poke around over the weekend to check the condition of the filters and oil etc.

Whilst under the bonnet, noticed some oily residue around the cam belt side of the engine bay.

I removed the engine cover and found the culprit although im not sure exactly what its for? (please see pics)

I've gathered its vacuum operated as the lever at the back moves when the throttle is pressed. I'm presuming its opening and closing some sort of flap within the intake manifold but thats as far as ive gone.

The car is covered by a third party warrenty, but i'm hoping its a cheapish part that i can replace without going through the paper trail with them.

Now this may or may not be the cause of the hesitation but imo if there is a vac leak there its not going to be helping the situation.

Any ideas or advice as to what the little sod is or a part number would be great, thanks in advance.

Oh and the car is my07 bkp 140.

Cheers
