018 ecu - you must solder

OK, today i used VAG COM to identify my ECU.... sad news for me it's 018 :oops: what now should i do? get ALH ecu from newer GOLF/BORA with 012 or solder my own ECU? any suggestions would be great! :idea:

dear colleges, need help.

There is no way to read or write this ECU without opening it up. Most people replace the chips with something like a 29F010B which makes them reflashable, but you still have to open the ECU.

:o that sounds great. can you give me some more info about 29F010B i could buy that, open my ecu, solder that chip, and then my ECU will be readable with MPPS?

EDIT: damn, now i understand, all the time i would like to change my map, i will need to open ecu, eject this chip ant reflash it on the eprom soft... i hate my ECU after that... can i swap to my car another ECU from 1,9 TDI ALH but with 012 ?
