A5/S5 VAG 5052 Coding

For anyone like myself with access to a factory VAG 5052 and not a Ross Tech scanner, here are the binary and even easier HEX codes for popular mods. Enjoy!


Enabling key memory in cars with electric, non-memory seats:
Module 36 Seat Memory Driver, 08 Coding, Master, change Byte 2 bit number 0, to value 1. Hex was 70 now should be HEX= 71 (Binary 01110001)

LEDs remain at full brightness with parking lights & LED DRL No Winking:
Module 09 (Central Electronics) 08 Coding, Master, Byte 03, HEX 15 (Binary 00010101)

Disable amber side makers:
Module 09 (Central Electronics), 08 Coding, Byte 10, set bit 3 to "0" (The binary representation of Byte 10 should be xxxx0xxx.) HEX = 00

Enabling reverse mirror tilt on cars without memory seats:
Module 52 (Door Electronics Pass.), 08 Coding, Byte 4. If the byte has value 40 (cars without electrically folding mirrors), change it to HEX = 4C.

Removing seat belt chime:
Module 17 Instrument Cluster, 08 Coding, Master, Byte0, HEX=8B, Should be HEX=83 (Binary 10000011)

Yes, I do not have memory seats either. I was able to turn on the memory seats via the coding. You can either have a VAG shop do it or if you know someone who works at a dealer. The Driver's seat menu will appear with the option for KEY ON, and then you will have memory seats for each key that you have. :)
