Just bought my car and I have been reading all the threads on upgrading to MCU2 and don’t think it’s practical for a 2013 P85 (I have no self driving, parking sensors etc.). I have a leaking MCU screen and have no choice but to replace it. My MCU1 system does not seem to be lagging at all and am wondering if there is a way to see if the EMMC has already been upgraded? I do not want to take the MCU out to replace the screen and have to do it again when the EMMC fails. Since I am doing this myself, is there anything else that I should replace while it’s out?
