I have a BMW 318D (E46) from 2003 and i'm looking for both cable for diagnostic and to reprogramming (put some more horses to drink). About 3 or 4 moths ago i bought ELM327 but i'm very disappointed because it won't detect the car connection.
I have read on the internet and now i'm confusing about brands and which are compatible with my car. I suppose it have to be with protocols.
Is there anyone who can help me to choose what can i buy to do what i want?
I also have damaged a remote car key and bought a new one last year but i never succeded to work with it. I could reprogramm the open and lock doors but when i turn it on the ignition nothing happens. Acoord what i have read, was something related to the imobilization code that have to be putted on the key chip.
Please if somebody could help on this matters
