If I give my '00 (83k) 1.8T Sport a fair old boot and take it through the rev range quite aggressively I sometimes lose turbo boost altogether.
I don't do this very often, so it's not a major issue right now, but I'm sure it could turn into one in the future.
Once I come to my destination, I switch off, do what I need to do and come back to the car and everything is fine again.
Am I right in thinking it's the 'N75 valve' that causes this... or is it something more serious? Will the fact that it's been re-mapped have anything to do with it? I've not got any receipts for the work carried out (previous owner lost it) but I do know it's a LOT faster than a standard 1.8T.
Cheers for any help...
