little update for you

I managed to get her started yesterday after trying various ways to get around the alarm and immob,got the alarm figured out and disabled and it still wouldn't start,then managed to trick the immobiliser and hey presto she fired up...
Once started it sounded very rough,thought it must be the fact i sprayed loads of carb cleaner down the throttle body and so on to solve the stalling and low idle at junctions... but it didn't pass and i noticed a strange tappet style noise

,i had a listen further down the engine and noticed it coming from the dizzy,so changed the dizzy cap and rotor and now its as sweet as a nut and cleaning the throttle body out has worked a treat no low idle or or stalling attempts for me

I know i said the new Ignition switch didn't work and that's true,but it has solved a little problem,i believed the switch would help as ive lost the live to the stereo and i believe thats a tell tale sign of an faulty Ignition Switch(as i read somewhere),i had also lost feed to the roof(which is in the same area of lume).
So Nitro the b33r's are def0 on me

For future reference to people with alarm and immob troubles i'd have a read and a good search on the VW section of this site for more understanding and tricks around the factory systems seemed to help me might be of use to someone else-:
