git-r,
Definately RWD, I thought I had a problem with the ATESSA pump at first, but since then I have had the frotn wheels in the air and they seem to turn, whilst the front prop shaft is still, so I think it can only be a problem with the front diff.
The torque guage does move, so the rest of the system I am assuming is fine, I don't get any errors from the ATESSA ECU either. Yep, she has a 38mm HKS external wastegate.
