I got my replacement maf from my euro car parts.........my mate ordered it cuz he's got his own workshop and it ended up costing me 66.66, i got a 12 month warranty on a refurbed bosch one.
 
No sorry, I was asking Craig! if he had an FMIC with the sort of speeds he was getting with a KO3. Didn't mean to hijack the thread.
 
went out in my mates pulsar today, that feels a little bit safer than my cupra but still pretty scary with loads of apexi and 4wd controlling it.......
 
Have you plugged the car into VAGCOM to see if there are any faults?
The Cupra is a complicated engine and it has numerous sensors, it could be any one of these that is causing the fault. It could also be a split hose etc.
