Audi A3 Quattro fluids.

[Belle427]

I've just purchased a 2012 Audi A3 Tdi Quattro 170 manual gearbox.
I know very little about the Quattro system but was thinking of doing the fluids.
Is it a transfer box and rear diff to do on them?
Will probably do gearbox too at the same time.

The A3 is a Haldex based system therefore it's a Haldex fluid and filter change. I think 2012 would be a Gen 4 Haldex.

Rear diff is separate fluid.

I believe the transfer box shares the oil with the gearbox.

Thanks, any recommendation where to buy the haldex service kit?

When I had a car with Haldex, I just got the dealer to do it.

A quick Google bring these guys up,

I would assume they are available on eBay as well as the usual VAG parts places.

Thanks, had a quick look today and the Haldex looks easy, it's a gen 4.
Just need to confirm now if the gearbox and transfer box share the same oil.
