Gearbox Oil And Rear Diff Oil Change In A4 B6 1.9tdi


Registered User

I'm changing the gearbox oil and have gone to audi and boight enough to change the gearbox oil.

But I've been reading loads online about it and a lot of people change their rear diff oil at the same time. I can't find the part no. of the rear diff oil for my car? Audi say it's just the same oil. But I read somewhere that there it is slightly different. Anyone know what part no. It is?
