Hi. When I reverse in the morning there is a slight grinding/whirring noise under the car. It also occurs as I stop on the incline to go out of the garage. My Audi dealer says it is probably the steering electro-hydraulics getting a little old. It will cost through labour, not parts. For now he says not to worry, but I have noticed this week the noise is slightly louder, but only first thing in the morning. Can anyone advise please? Does it need doing? ( I live in Spain so specialised car vocabulary in Spanish is not my forte, although the garage has been really good) Thanks, Ivor.
