    Hi, looking at changing the rear diff oil and the gearbox oil (manual 6 speed) in my 1.8T quattro s-line soon, what would you guys recommend i change it with, i have a TPS account so would it be best just to get the genuine stuff from them knowing it will be correct for my vehicle.

    I just got the genuine stuff, at main dealer parts prices it was about £86 though. Still, it hadn't been changed for 120,000 miles, and probably won't need doing again!

    I think it was 2.7 litres for the gearbox, and 1.5 litres for the rear diff, though it was different stuff front to rear.

    AG 051 911 A2 - Gearbox Oil - 3 x 1ltr bottles £14.97 excl VAT each

    AG 052 145 A1 - Diff Oil - 3 x 0.5ltr bottles £8.75 excl VAT each

    I have the 5 speed box though, so yours might be different, just check, but the parts guy said it was the same for all the quattro's. I had to buy a splined drive socket with the hole in the middle to remove the gearbox drain plug, and used a piece of hosepipe and funnel to refill. Check your fill plugs will come out before you drain too, my rear diff one was a pig to get out!
