andy, i'm not sure i'm getting your street chat here.. 
when i floor it, there is one big backfire when the throttle is pushed to the floor. it never does it if i take the acceleration gradually up and over the 4000rpm mark, only when i plant the boot. i guess i'll have to get it into the garage and have them check it. i'm going to go ahead and get the cambelt etc done on it so might as well get the misfire seen to as well. at least that will save me farting around with leads when it might be something simpler.
many thanks.

WOT-wide open throttle
POS also stands for piece of **** (as the only time you have anything to do with the power output stage is when its acting up
)From SJM, good info on missfires under load, POS description etc
450nm for crank pulley with Audi tools, often done as 200nm+180degrees as a DIY alternative. You will need a big torque wrench (norbar 5r style), or a big breaker bar/scaffold tube)
Crank pulley is about £30 from audi, or about £100 for an after market billet one, its bolted to the back of the harmonic damper/accessory drive, pictures from when I changed mine;
