Okay, I found a scan of mine at work (don't ask why) and It appears that my car has vaguely different coding. I could find following changes, that are not explained by changes MasterTommy made:
Byte 08 > Bit 7 (me: disabled)
Byte 09 > Bit 1 (me: enabled) and Bit 2 (me: disabled)
Byte 10 > Bit 0 (me: disabled)
Byte 12 > Bit 0 (me: disabled)
Byte 13 > Bit 0 (me: disabled)
Byte 23 > Bit 5 (me: disabled)
I also found that my module is version 0020, whereas MasterTommy's is 0021, part number is identical on the other hand.
Byte 08 bit 7: location_lordosis_button, active (probably lumbar support button)
Byte 09 bit 1-2 (drop-down menu):
- 02 func_key_memory_personalization, personalization active.
This is your problem probably.
Other possible options for this bit:
- 00 func_key_memory_personalization, radio-controlled key memory and personalization not active
- 04 func_key_memory_personalization, radio-controlled key memory active
- 06 func_key_memory_personalization, radio-controlled key memory and personalization not active (looks the same as option 00)
Byte 10 bit 0 (drop-down menu): 01 SLV_positioning, hall_with_hall_errortest (something about one of the adjustment motors)
Byte 12 bit 0 (drop-down menu): 01 SHV_positioning, hall_with_hall_errortest
Byte 13 bit 0 (drop-down menu): 01 SNV_positioning, hall_with_hall_errortest
Byte 23 bit 5: memory_keyboard, 0=VW_resistance_coding / 1=Audi_resistance_coding
I'd try changing byte 9 to what i have.
If that doesnt work, unit 09 also has some general personalization options under adaptation (security code 31347):
