As I promised you in my previous post (BMW E36 OBC (On Board Computer) Manual – Part 1) which I published yesterday, here’s the second part of the BMW E36 OBC manual. It turned out that it’s a valuable source of information. I didn’t really expect the manual to be this precise, but you know what. It is precise. I really enjoyed the information it provided.

I hope you find this post useful. Now it’s time for you to try this information on your car, so hurry up. What are you waiting for? 🙂

On-Board Computer Manual
 

Speed Limit (LIMIT)

If you exceed a speed limit which you have previously input (for instance in order not to infringe legal road speed limits), you will hear a warning gong. The corresponding LED flashes and the display shows the stored limit briefly.
The warning is repeated if the speed limit is again exceeded after the car’s speed has in the meantime dropped by at least 5 km/h.

Speed limit input:
Press the keys in the order illustrated above. The LED will come on.
Cancelling the speed limit input:
Press the LIMIT button again. The LED goes out, but the stored value is retained and can be re-activated with the LIMIT button.
Adopting the car’s actual speed as the limit value:
Press the LIMIT and SET/RES buttons.

– Input the code number at the numerical input keys.
– Start the engine or press the SET/RES key.
If attempts are made to start the engine without a code input, the gong will sound and the engine will not start.
The alarm will sound for 30 seconds after three incorrect code inputs or three attempts to start the engine without a code input.
If the code number has been forgotten, proceed as follows:
– Disconnect the battery, then reconnect it after app. 2 minutes.
– Turn the ignition key to position 1.
– The alarm will sound and a time display will appear and run down for 15 minutes.
– After 15 minutes, the engine can be started.

    Hi All,

    I have a 1994 740i. Recently the on board computer display switched to French, then German, now its in Italian. Does anyone know how to change the language setting so I can switch it back to English?

    thanks,
