I have an Octavia 1.8t 2003mod AUM engine automatic transm. with ECU 06A906032HL.
Is it possible for me to use for example 06A906032HJ ?
I'm just wondering what the main difference is between the ECU's, that all have the same part no, except from the last two letters.
Do you think I can use any ECU that have a part no like: 06A906032XX ?
Do they all have the same HW inside?
