E-Sys coding cheat sheet for G20/G21

Great resource! One thing to add - for G20 you need E-Sys 3.33+ with PSdZData 4.32 or newer. Older versions wont have the correct FDL files for G series. Also make sure to create a backup of every module before you change anything. I bricked my headunit once and the backup saved me.

For anyone new to E-Sys on G20: the most popular codings are digital speedo (HU_MGU > 3040 TACHO), folding mirrors on lock (BDC_BODY > MIRROR_FOLDING), and disabling auto start-stop default (DME > START_STOP_DEFAULT). These are all safe and reversible.
