I've been playing with the obc in my compact. It's a digtal display job with two buttons underneath (one with a clock symbol to swithch back to the time and a reset button) the functions been controled by the button on the end of the indicator stalk. Usualy goes through a cycle of.
Time Temp Ave-MPG Ave-MPH Milage left in tank (maybe not in this exact order.) The temp is in deg F. everything else is in Miles. I was setting the clock by pressing both buttons etc. but decided to have a play and found out how to change the clock from 24h to 12h, but have also noticed the display comes up with '01' and when I press the stalk it goes through '01' '02' '03' '04' whatever this does I don't know. Also on two occasions I have managed to get '1000' up on the display, and ny pressing a button (can't remember which one) it goes up, got it to '1015' and I haven't a clue what it does. I thought I might be able to set the temp to deg C, as the dealers haven't a clue how to do this. Anyone have a clue what this all means and what it does? (sometimes the display lights up fully with everything showing) Any ideas? |

This might help .... Stephen
E36 On-Board Computer (OBC) Hidden Codes and Tests There are many interesting functions available on the E36 OBC that are not documented in the owner's manual, including changing the language of the display. The procedures described here work on my '97 328iC, which has the upgraded OBC - they may work on other models of similar vintage. There are some links at the bottom of the page for information on other OBCs, and for setting the language if you don't have the OBC. You can also find information on hidden tests for the instrument panel. Contents:
Programming the OBC to Display Contents in a Desired Order When you repeatedly press in on the turn signal stalk, the OBC display cycles through the various information types that it has in memory. The default sequence is: CONSUM1, CONSUM2, EXT. TEMP, SPEED, LIMIT, DIST and TIMER. If you want to change the display order, use the following procedure: Press in and hold the turn stalk for about 5 seconds. The OBC display will change to Prog 1. Press the button corresponding to the first function you would like to have displayed in the sequence. For example, if you would like the outside temperature to be displayed first, press the TEMP button. The display will then change to Prog 2. Continue pressing the OBC buttons in the order you want, up through nine entries. You don't have to enter all nine - if you would like the display to cycle only between TEMP and RANGE, simply enter those two items as Prog 1 and Prog 2. When finished, press the SET/RES button to store the sequence in memory. To revert to the default order, simply press SET/RES as soon as Prog 1 is displayed. The OBC contains a lot of data, and displays the data in a manner determined by the country code that is stored in it. The technique to access this data is as follows:
Unlock the Display. Most of the test sequences require you to first unlock the display before. Enter test code 19 using the above procedure. The display should read LOCK: ON. Then enter an unlocking code consisting of the sum of the current month plus date (for example, if today is July 11, enter 18). Then press SET/RES, and the OBC is now unlocked. Test Codes. Following is a listing of the available tests, along with with my notes as to what I think each test means. Note that the display uses European conventions for decimals (i.e., the number 61,7 is 61.7 for us Americans). You will see that I don't have good explanations for several of these test codes -- if you have any information that can help me make this table more complete, please email me at ebaines@att.net.
Setting the Country Code. If your OBC suddenly starts displaying everything in German, and you would like to put it back to English, use test sequence number 10. Once you're into test number 10, press the 1 key several times, and you'll see the display cycle through various country options. For example, 0 is for

Rhys, you beat me to it, was going to post this question myself.
I too have tried what you have mentioned to no avail! Stephen, thanks. Will give it a try tomorrow! |
