I understand that the M111 engine is fitted with VVT (Variable Valve Timing). My recently purchased car has covered 6k miles in the past 5 years whilst in custody of the previous owner, mostly at low speeds (and probably at low engine speeds).
The VVT buzzes at approx 2,000 rev/min, mainly whenever I change gear (my car is fitted with a manual gearbox).
The noise is a bit like a hard rattle, but not particularly loud, at least not inside the car, although it is quite loud with the bonnet up, if that makes sense.
Would driving at higher engine speeds revive the lazy VVT actuator? On a couple of occasions when I revved the car up to 5,000 rev/min the actuator seemed to quieten down afterwards.
Any advice please?
