Thanks a lot for the help guys. Have spoken to several VW specialists who think its unlikely to be related to be the map sensor, however the VW dealer has run the vag com apparantly, so unsure. If the main issue was the throttle body, how come the idle in neutral is fine, but coming to a stop it stalls? Are you sure the brake switch is £5?? I have had quotes from independants of £30 incl fitting and the VW dealer quoted £100incl fitting.
