A5 gearbox and diff oil change?

Hello everyone good to be part of this forum. I have a technical Q about changing the oil I would like to know where the drain and fill plugs are located ? I have just purchased 5 litres but its in 1 single container, will I need to use a 1L squeezer to fill both and could do with knowing what quantities in each? and as title says where are the fill and drain plugs are? 2008 3.0 tdi Quattro- possibly covered before please point in the right direction (other than FWD) nice one cheers for any help!!

Before you start anything have you got VCDS as you'll need it.

Which diff, there are 3? Which gearbox, manual or auto?

hi, yes I have VCDS, and its the 6 speed manual gearbox, don't know what gearbox code is it on the label in the service book/trunk ?

sorry but can you confirm the oil for both rear diff and gearbox are the same 75w 90 fully synthetic ?

gearbox code is KMU & rear final drive is JKQ?

Any help to confirm the detail above would be really appreciated - Nice one.

VAG don’t specify what it is but the transmission fluid shown for the type 0B4 KMU code box and its integral front and centre differentials is G 052 911 A1 or A2 (3.8 Litres dry capacity) which Febi specify as being

API GL-5, MIL-L-2105 D, MTF LT-2, MTF LT-3, SAE 75W-80, Yellow, Oil Viscosity Classification SAE: 75W-80 for manual transmission

The rear differential type 0BC code JKQ oil is listed as G 052 145 S2 or A1. And is described by Febi as

GL-5, SAE 75 W 90, SAE 75W-90, VW 501.50, Yellow, for manual gearbox and rear axle differential

The gearbox oil filter plug is on the left side of the gearbox directly below the clutch slave cylinder.
