have a strange new noise for my 2012 Jetta .. i bought this new and it has 135.000 miles now. . i hear a strange whine when its in gear under throttle. kind of a whine buzzing sound. i start it.. rev up. no noise clutch out to go forward and the whine starts.. i can clutch in while moving and it stops.. it follows speed in each gear as i throttle up... but is the same in every gear. it doesn't increase and sound faster as i shift up gears and gain speed. .. and as soon as i push clutch in in any gear it stops. .. thanks in advance for any ideas.. Roy ..
