    If its a tired pump then an inline pump is not a fix... do you have logs to support the AFR on the dyno graph? need to check requested vs actual... could be the maps actually asking for that AFR...

    Its most likely the pump in which case a new one is required but would need to see the AFR logs from VCDS to confirm...

    Not sure what his schedule is like but I suspect there would be easily time for a road log if nothing else as it will be evident fairly quickly whats going on

    May see you tomorrow then...
