im buying a '98 A3 1.8T (Originally an throttle cable AGU) which needs engine, gearbox, wiring loom and ecu (All sold seperatly by current owner)
i have a complete car breaking at work on a 2003 53 plate (last of the facelift 8L's) with an AUM (Fly by Wire throttle)
will it be easier to fit the pedal box etc to convert the '98 to fly by wire or fit an earlier cable throttle body?
also, if i fit the earlier throttle body, will the ECU work ok without a feed from the throttle pedal?
anyone have any ideas??
