It doesnt sound major but the whining noise from the engine is quite loud. it wouldn't be the guides for the chain would it?

Nope, don't know of any engine generated noises that I would describe as a whine.
Take the belts off the front and run it for a few seconds without them to see if that looses the whine.

dont know about whine but if its the guides/tensioner it would be a raspy sound at about 2.5 - 3k rpm - is it any different when its hot or cold or still the same??

A whine sounds like a pully bearing or something... water-pump or alternator bearings maybe?

no real whine at low revs but it get louder as it gets faster. my M40 had the same whine but not as noisey. i'll take the belts off and let you know. would a belt whine if a little too tight?

could possibly also be the diff.....

agree with Zaust that it could also be wheel bearing - when at its loudest or at speed turn the wheel or change lanes and see if it goes quiet - if so then its a wheel bearing...
