@Disid1945 Apr 06, 2021MemberHey everyone, I’ve just got my first new-style mini (My last one before this was 1973 with a 1275 GT engine!)
It’s a chili red (don’t ask) mini one from late 2006 but still Generation 1.
The problem is the OBD port not working
It connects with the reader (I use Carly) but doesn’t communicate with it.
The ELM light and the engine management light come on and off again on startup.
The 12V cigarette lighter socket is getting power, through testing off it isn’t working at the moment. I’ll clean it to see if it helps.
The cover is missing from the fuse box so I don’t know which fuse is which and I can’t find the diagram for it online (f1-f40).
Does anyone know what could be wrong with my Mini Cooper’s OBD port?

The cigarette lighter port and auxiliary port fuses can all be connected to the old socket. You should test every fuse with a multimeter. I once spent ages trying to find the cause of a lack of voltage and when I finally went back over every fuse with a multimeter found that one was cracked even though it looked fine from the outside.
