[M6Havana]

Ive noticed a high pitched noise on cold start or when sat for 1hr+ and restarted but not as apparent as a full cold start. It almost sounds like an insects wings (weird comparison) but thats all i can describe. I think its belt related as the noise does fluctuate when reving.. im not sure how to uploads videos on here but without looking it seems to come from the left side of the engine with my windows down RHD
