I have just purchased a '09 A5 2.7 Multi-tronic.
I've never owned an automatic before so I'm hoping someone here can answer a few questions for me.
is it normal that this car should have a low whine at low speeds and at idle?
Also when the car is in reverse, the cars makes a sort of grinding noise, not while the car is moving but if I stop.
it only lasts for a few seconds, then stops for a while and then does it again?
I had the car on a hill, front pointing down the hill and put the car in R, it holds fine but the 'grinding' noise is constant.
Is this normal?
I appreciate any replies,
