I seem to have some problems with some of the functions on my E34 5353i OBC.

1. Using the "CONSUM" function (cons1 & 2), the OBC always displays --.- L:100, even after pressing the S/R button



2. Using the "SPEED" function, this always displays --.- (Can't calculate an average speed), even after pressing the S/R button.



3. When using the "LIMIT" function (Speed warning), I set a speed, but I hear no audiable noise after the speed is reached.

All the other OBC functions work eg HR/DATE, RANGE, TEMP, TIMER, ARR, DIST etc.

I have also noticed that there is no audiable alert when the handbrake is on and the gearbox is in "D" or "R". Should there be an audiable alert ?

Reading through the forum I noticed the test features on the OBC. I have got into test feature 19 to unlock the OBC, but I don't have the right code to unlock it. Does anyone know the code to unlock the OBC ?
