    bet you it's a NDW model with the read only ecu, on those you neeed to completly replace theh ecu with a freshly burned one

    I've got an October 98 S4, so one of the first ones made. MRC mapped mine without having to replace the ECU.

    On the earlier ones its a replacement chip job on the ECU, the DBW models with the later ME7 ecu can be flashed

    You do not need to replace the chip in an S4!!!

    All S4's are DBW, and all can be mapped via the OBDII port.

    98 S4 will need the chip replaced or at least done on the bench in boot mode. Not possible to do over OBD. This is true for most VAg ECU's upto September 1999. There are of course some exceptions to the rule.

    Thanks.

    My ECU was removed from the car the first time to 'unlock' it, but i've since had 3 remaps done via the OBD.
