Gearbox Service Kits - 0AW and NDU

[Adam Watson]

I need to service the gearbox on a 2014 A4 Avant FWD with gearbox code NDU. All the kits I find which are listed as for 0AW gearbox, are they the same or do I need a different kit?

thanks
Adam

NDU is 0AW serines, in the case of the NDU 0AW 300 046 R 006. The fluid is G 052 516 A2. A standard drain will only get approx. 50% of the old fluid out, to get approx 90% out, a special purging procedure is required whereby you can get approx 6 litres out of the 8 litre dry capacity. The externally accessible filter is 0AW 301 516 H and we would use the Febi 176878 kit

Thanks, ordered a kit. Is the procedure to get the extra oil out described anywhere? I have watched a couple of videos where you hook out a little tube to get more oil out, is it more involved than that?

Quite involved, I can't post it on here without a lot of effort so go to erWin and download the procedure for €7. This is the menu for the procedure.

ATF purging procedure Special tools and workshop equipment required t Vehicle diagnostic tester Procedure A normal ATF change involves replacing only approx. 55 ... 60 % of the total ATF in the gearbox. The “ATF purging procedure” has to be employed if all the old ATF in the gearbox is to be removed. ATF purging is always necessary when performing the following work: t Renewing the input shaft t Servicing the input shaft This involves performing the road test twice, as described below, and then changing the ATF. This is the only way to ensure complete renewal of the ATF in the gearbox. The work required for the ATF purging procedure is described below in seven steps. Caution Risk of damage to gearbox It is important to exactly follow all the described steps. – Fill up with ATF after installing gearbox → Chapter „Filling up with ATF (for ATF purging procedure)“.
