Hi guys
I desperately need your help

been out for the day in the passat (2006 Tdi 140 sport)
when we got back to the car to come home the exhaust emmission light was on and the glow plug light flashing when i started the engine
An emmission fault message came on and it told me to go to the garage

has anyone got any thoughts

also the aircon started to loose the cool air just before we stoped

cheers

andy
