As above really and bad mpg Asz engine ? Thanks

it needs mapping out and cannot just be pulled off

Thought it was only blt engines that put a light on I know it needs mapping out but why low mpg ?

you fitted it properly? and yeah its only BLT that pulls a light, if ASZ does you can just delete it i think. use to be on that fabiavrs web page dontknow if it still runs.

I haven't blocked the vacums though as if been told not too but might block them up in the morning

Boost leak?

if you have go or can get access to vcds you could try the proccess on this page nearish to the bottom ??
