Looking for help for a friend, here is the information i've been provided

  • emission light has been coming up for a few months
  • my dad didnt bother looking at it
  • the onboard cpu says "emissions workshop"
  • i've looked on the net for problems found a few helpers and got my hands dirty but still its on
  • it's not the egr valve
  • it's not the intake sensor


Anyone got any ideas or is he going to have to take it to a garage?
 
MAF sensor? It seems to be a common fault on VAG motors and when it went on my car (1.8T) it made *** emissions light come on.
