    I have recently purchased an A4 and on the way home I heard the faint noise of what could be a diff whine, a trip to my local garage confirmed that the whine is most likely the diff so they replaced the gearbox oil, what they found was that the gearbox only had 750ml of oil in it, a quick call to Audi confirmed it should be 2.2 litres. The gearbox was then filled with the correct oil.

    Luckily the noise has quietened a good bit but is JUST audible.

    Anybody replaced the 6 spd box? How much would I be looking at for a replacement or rebuild should he noise get any worse?

    the thing i would be looking for first is wher the oil went, possible leak?

    No leaks visible.

    Also... why is this site soooooo slow, takes 2 mins to load pages?

    the 6 speed is known for weak pinion bearings. Yours could now be excessively worn due to lack of oil.

    As long as its full of oil it will probably get no worse, but i'd deffo check for a leak, probably from one of the drive flanges

    Thanks for the replies.

    Im thinking its human error as Ive seen the car up on ramps and its dry as a bone underneath, infact, its like new.

    Ive had BMW's the same age/mileage and they werent as clean as this car underneath.
