    1. Post an complete autoscan. Best if You have scans with old and with new ECU's.
    2. For that age of TDI/SDI engines there are only two coding options. 00001 for AT and 00002 for MT.
    P.S. Lazy people use to code MT ECU as AT instead of repairing/replacing starter, replacing weak battery, cleaning ground connections etc. to get better starting behavior.
