A4 Allroad B8 - Torsen or Haldex???

[Nigel22]

Hi, first time I've joined a forum for Audi, even though owned them for years.

Anyway, hoping someone can shed some light.

I've asked Audi which systme my allroad is on, and even they were a little unsure, which has left me concerned, especially as I'm keen to do the tranmission/gearbox/diff oil changes if it's necessary.

They said it is a sealed system and I therefore don't need to change the oil in any of those systems. Doesn't sound right to me!

I've driven 185k miles with absolutely no issues, other than cv joints replaced, calipers on front brakes, utility belt and some of the pulleys.

About to change the rear shocks and bump stops so wanted to get any oil changes done whilst under there.

Appreciate any advice.

Thanks
