Found this link to swedespeed on the V50 forum here. It how they have upgraded a AWD V50 from Haldex GEN2 to GEN 3 by simply swapping over the haldex controller, solenoid and pressure valve from a V8 XC90. A very simple task.
Might this also be possible on the P2 V70's or XC 70's??
There is talk on swedespeed about trying the mod on an P2 V70 AWD R - as an owner of said vehicle I will watch that space - so to speak with interest.
