since Justin always has the answers to my dumb questions: Justin, could you post a pic of each, so I can see which one I have. then perhaps explain the differences. thanks! hope i'm not too annoying with these questions...

@BMWFORLIFE: what kinda car do you have? is your also a 318 convertible?
Sure.

7 Button: Ambient tempature, time/date, has a memo function as well. Uses a reverse Liquid Crystal Display for both displays. (backlit).



------

11 Button: The above, plus Check Control (light failures, washer fluid level, coolant level, etc.) Easier input for numbers, and a dot matrix display on the left, and the same LCD display for the date/time on the right. Both backlit.



------

18 Button: All of the above, plus it has calculator functions using data provided by the ECU and instrument cluster. It will calculate things such as: estimated time of arrival, range on remaining fuel, average speed, fuel consumption readings, speed limit warning, timer for opening/closing ventilation when the car is parked, and CODE for vehicle immobilization. Same displays at the 11 Button.

It's interesting that at realoem.com it shows parts #1 and #2 as seperate pieces... but no price for #2... by the diagram it looks like you could just buy the extra buttons?

You will need a new face for it. New buttons have plastic springs behind them, and a new light transmitter behind it. Buttons will need to be re-soldiered into the OBC itself using the wire strip. But yes, the OBC's circuit board on the 11 button Siemens is capable of handling the 18 button functions. The BORG OBC, (typically what we have in Canada), is a completely different circuit board. You will also need to wire up a new male connector on the back of the OBC itself for the extra wiring harness, which has multiple insertion points on the circuit board itself. (3, I believe.)

wow, now im kind of jealous. didn't know there were such cool functions for the E36.

by the looks of the pics, im sporting the super-basic 7-button OBC.

if i buy an 18-button, would it work in my car?

hey Proprone! Think about picking up a new microfilter since you'll have your glove box out for the obc swap anyway. Might as well change it, it's probably been a while. Dave

Nope.. I'm like you with a 7 button. To wire up to an 11 button we need A LOT OF rewiring done, have to practically gut the car getting those wires everywhere for all the different sensors. To upgrade to an 18 button we have to tap into other wires behind the dashboard, not as tough.. a little tedious.

what's the deal with your car, proprone? you keep mentioning its in the shop...

and Justin, thats pretty shitty for me. cuz i really like that 18-button OBC. seems damn cool. so which cars came with it stock? if i end up selling mine to pick up another 318 or a 328 (5-spd), i will want one with an 18, or at least 11-button OBC. so, what do i need to know?

It was an optional upgrade.. some cars may have it, some may not. Rare that you'll find early e36's with the 18 button as the upgrade for it back then was an arm and a leg.

The functions are very cool.. but when I think about it, we have an 84 Jaguar XJ12 sitting in the garage and it has all those features, plus more... and that was stock. Not bad for an early 80's car.

Im going to be doing this swap soon and maybe you can be of help.

First off, did you use this site for the instructions on how to do it

http://www.geocities.com/e36rulz/OBCconversion.html

and If so were you readily able to find the second harness or did it come with the OBC you bought.

when I did mine it came with the other plug.

I used this article
http://www.pelicanparts.com/BMW/tech...BD_Convert.htm

I found it way easier and it worked just as good.

What year is your car and what OBC do you have now?
