Audi Repair Questions? Ask a Mechanic for Answers ASAP
is that headlight flickering?
if you turn the lights off does the noise stop?
if you run the engine and pump the brake pedal does the noise change ?
Ok in that case I'd say to check the oil level in the gearbox as the next step
take a look at the colour of the transmission oil it should be a dark red colour if its black then its needs changing together with its oil filter. Also check its level with the gearbox warm and just after you've moved the selector through all the positions leaving it for a few seconds in each one and then back to park.
You can top up the box through the side fill plug if required and make sure you use the correct oil for your car as the fluids are not all the same. Some manufacturers recommended a change of the type of fluid - Speak to the local dealer and parts dept - they will advise you on the updated fluid to use..
I think as long as you don't have any slipping / struggling to accelerate or any error / fault lights on then you'll be OK
