My bet is that it will be infamous 'boost pressure control - positive devaiation' fault. (stuck VNT mechanism)

yer mine has done it about 3 times and its usally after i give it a boot along a road (staying within the speed limit)  :grin: and then go around a corner. But it isnt anything to worry about.

lol i have a different opinion, your car going into limp mode after accelerating is something to be concerned about! Especially if you know how to make it do it.
