HI

so far its all good,379 bhp,301 lbs/ft tourque @ 152 mph.
emerald m3d,gt3071r,630cc injectors,the list goes on,however my air con no longer switches on,the vw ecu is still connected but with limited functions ie temp for gauge,cooling fans,basic stuff....
any ideas..

Fuse? Or relay?  Did you do some custom wiring or something?

yes its stand alone management,,looks like the vw ecu sends the signal to authorise switch on,think im going to add an additional relay to power the oe air con relay.

I was just reading through my Bentley, looking for the wiring layout.  Seems like there would be a need for a relay.
