Haldex Service

[jonnydiesel]

When will the Haldex on my B6 Quattro Sport avant 1.9 TDI need it’s oil changed or is it sealed for life.

A4 Quattro's do not have a haldex, they use a Torsen Differential. I can't tell you when it needs it's service though sorry, but I'd like to know the answer as well.

The Torsen-based Quattro system is pretty much maintenence-free, IIRC.
