I have a whine that I assume is from the gearbox - the best way I can describe it is like an older non synchro car reversing, but quieter. It appears to be linked to engine revs.
I only had time for a very quick 2 minute drive so it is difficult to pinpoint position etc. Could it be anything that we did, or is it coincidence.
Any thoughts are greatly appreciated.
