You could adapt Golf/A3 1.8T ecu, which is M3.8.3 and with 29f200 chip. There's also equivalent A4 ecu with same flash chip, for example 8D0907559C (have not seen it, but file size is the same 256k). I think this is US model, so might be harder to find.
These can be programmed via OBD (not with all tools), if you connect a wake-up voltage to ecu pin 43. Your car might already have a wire routed from this ECU pin to OBD pin 13.
