[nov]

last few weeks ive noticed a weird noise coming from the engine bay
sitting at a roundabout first gear i pull away and get a weird noise sometimes while pulling away not all the time tho.
and when selecting reverse and i throttle up i get this weird noise

the noise sounds like a wooden chair being dragged across a wood floor and only happens for about 2 secs ?

anyone any idea what it could be
