71 Kombi, when under acceleration, it makes sort of a whining sound, but stops when backing off accelerator. Any common causes?
shano

i was thinking maybe mother inlaw on the roof:thumb
but seriously maybe an airleak

Different kettle of fish perhaps but the ex cop VP I had the misfortune of owning had a real high pitch whine under acceleration or when at constant speed, quieter when backed off but still there. The whole diff, axle & bearings assembly had to be replaced & the guys in the workshop said it was the worst they had seen & couldn't re-use as much as they had hoped. But dont they always say that :thumb

Yours may not be as sinister, could just be an airleak etc as suggested, hope so for your sake...good luck

On the plus side the car was stolen from my driveway about a month before I had the diff done so they dumped it about 500m from our house in a back street Must have figured it wasnt worth a brass razoo. Not far from the truth... Nowadays its line-ball whether the whine is louder from the passenger seat, or the kids in the back when we go past a Macca's
