Default 316i Compact OnBoard Computer Retrofit

Hi all,

I wonder if someone can help me with details of the parts required to retrofit a 2 button OBC into a Compact.

I know I need the following
1. The OBC Unit with thin connection wiring
2. Selector Stalk
Are there any other bits?

Also, where does the OBC connect to ? Should there be a spare socket on the rear of the instrument cluster ?

I'm planning on doing that retrofit this Sunday. You will need a harness to connect everything. I was wondering if there is anything behind the cluster to deal with too. I don't think there is. I can see what parts I have at home, to give you a more precise parts list. I don't have the OBC computer/clock , so I will not actually be completing this mod on Sunday.

I'm reasonably certain you connect to the ECU, and not the cluster. But, I don't have one and don't plan to, so I am not the authority on this...

You are an absolute star - thank's a million for this. I now know what I'm letting myself in for which thankfully looks reasonably straight forward.

Sorry guys,

One final (I hope) question.

It says on the instructions that the "vehicle data must be programmed into the unit within 36 hrs"

If I bought a second hand unit which came from a 316i, would this mean that this step would NOT be required ?

I'm starting this update tomorrow, and I do not have the OBC computer. I wonder if I install all the wiring, and leave the cable that connects to the computer off, is the 36 hour time limit an issue.

If it came from a car with the same engine, there's a good chance you can skip the coding.

Can you please let me know the part number of the Wiring Loom that you are installing since it looks as though there could be two possible ones.

It will be interesting to hear how well the BMW instructions match up to your actual experience

As long as you don't plug in the computer it will be fine.

Good luck and wire away!

After you wire up the OBC, you take the car to a BMW dealer, they will hook it up to their workshop computer and then "code" (program) the OBC so that it knows what is in the car.
