Yeah it looks like it would be bad if it hadn't. But Mike from prestige and performance said that if it was due to the haldex not being serviced properly it would cause the rear axle to stay bound rather than unbound. So he seemed to think from my brief description that it may be the controller or the pre-charge pump. However he said the launch technique might be an alright idea.

Gavin, if I went out and did a few launches tomorrow morning and stuff, and then found that my 4motion system was not working would you be able to scan it in the afternoon?

Cheers,
