So complicated, yet so interesting to find out what these cars can offer. Okay, so with those climate control LCD codes....on a 1993 500SEL, think it might work? We bought the car used, I have not asked the dealer to check upgrade history. But I think I read somewhere that there was a "software upgrade" that was done to S classes back then. I don't know if this has been done, and dont want to accidentally change something in the car...who knows, one wrong push of the Rest button and the fuel door might not unlock two days later!!
So, any insight on the 93 will help also,
Thanks for making this available,
