Hi guys,
Got an odd noise I'm trying to identify on the Vec....yes I know its not a HDi but it's near enough the same lol.
Basically, briefly (a second or so) on start-up, continuous under load up hill and breifly (a second or so) on low gearchanges (so slight load changing up at 1500rpm'ish say) theres a loud chirping noise. Loud enough to just hear with the window up.
Its not clutch slip as I always start the car with the clutch down.
It could be a belt slipping but if that was the case I should be able to replicate it at a standstill by loading the engine with the handbrake on and I can't.
Can it be diesel knock? Seems a bit specific though, and higher pitch than Im used to.
Only other thing I wondered is can a small air leak somewhere cause a chirp noise at the times I specified above?
Any ideas lol?
Tom
