hi, I have searched and searched many places for an answer or help to my question and I hope this is the right place to post.
I bought a 1996 318i for my son, it has the 7 button basic OBC and we picke dup an 11 button to replace it to try and get the check function and all that.. I have only found threads about the 18 button upgrades etc.
It seemed to be a straight swap with the one connecter in the back. It works fine as far as lighting up and displaying time and date and it will do a display test which I belive is test 00 or something. We try test 19 and it does not come up with the words lock on or lock off or any such thing.
The problem here is that I am blind and I am trying to help a 17 year old with this and keeping his focus can be hard lol.
I have a couple of specific questions that I hope you all can answer.
1. Is there a way to check if the car actually has the check code module? If not then I am wasting my time.
2. If it does have it, do we need to sync it with the car somehow?
3. If we do, How do we do it. I have foudn threads talking about hexidecimal codes anda bunch of different options then it will say well this doesnt work blah blah blah and then the thread ends. It is like leaving a movie ten minutes before the end and not knowing what happened.
I have read quite a few threads on here about different things and you all seem to finish and report all findings very well, and i am confidident someone can help.
This is our first BMW and I know it is a lot different from other makes.
I also have a problem with the central locking system and I foudn a thread on here that we are going to follow that was very helpful with diagnostics, Could this be related to the problem of the OBC not functioning correctly?
Hit me with your questions and I will answer them as best I can and as quickly as I can, Thanks in advance for any ideas or suggestions
