So I was inspired by a "how to" BMWscanner 1.4 link that Overboost provided in a previous thread to try and recode my temp guage. Mucked around a bit last night and wasn't succesful (most of the info is for E46, E39 etc.) but sure looks do-able. I think I just need to use NCS expert dummy or try out the checksum fixer in BMWscanner. Has anyone done this on an E53?
