    Hi I've got a 2000 A3 tdi 110hp non pd. The fuel economy is bloody awful 30mpg at best. Have got vag commander but not installed it yet. Car runs fine as far as I can tell no misfires or judders pulls okay for a 110 tdi.
    Anyone got any ideas i was thinking cat. It's been serviced a couple of weeks ago all genuine filters and oil etc...
