Hi, I've got a 2000 plate mk4 AGU 1.8t Golf, and the guy i bought it off said that he has had it remapped just by plugging it into the odb port, without removing the ecu - By a "mate". How believable is this? because the ECU in the AGU isn't programmable unless the chip is changed (or so i've heard), and i really don't believe that he changed the chip in it, so that he could get it remapped.
Thanks, Mo
