Good day all. Have a strange noise coming from the throttle body on my mk1 1.9 fabia diesel. It buzzes for approximately four seconds when the ignition key is turned on and continues to buzz for four seconds, then off for four seconds, then on again four seconds all the time the ignition is on. No hit on performance, no warning lights, nuffink! Just this buzzing from the throttle body which you can feel if you put your hand on it. Any ideas please? Tank you

ASY engine

Its the position sensor. 

Need a new TB

Ignore it, if it ain't broke yet...
