Following on from my lumpy running, have you checked the vacuum hoses?  Worth a look, and a replacement.  Mines running a bit rough, but it's only split a ltitle.  If you've got a totally perished one, might be an issue?

right got it started now
it runs ok for a minute then it wnts 2 cut out and then it wont rev past 4grand n then it just bogs down complely

any ideas

i cant remember why, but when it wont rev that high its becuase the ecu is in safe mode becuase of a fault.

get it hooked onto VAG.com and find the fault and clear them.

Have a look in the maintenance section, Bradley has written up a few points for poor running.  Poor cambelt adjustment can cause the engine to go into safe mode?
