How to UNLOCK the OBC/Instrument Cluster
 
Don't freak out...you probably didn't do anything. Once you turn the ignition off or press & hold the CC (check control button) for a few seconds...you cancel this feature. If you didn't have the instructions to UNLOCK the OBC...you probably didn't do anything. In the future, if you run across any of the "hidden" service mode stuff... ask the forum and wait until you get the information you need to understand what you're seeing to avoid messing up a components settings or calculations. You don't want to change stuff that you don't know how to reset...or reset stuff that you didn't know you were resetting.

Only TEST 1, 2, and #19 are UNLOCKED. And to UNLOCK the other 21 TESTs...requires adding up the LAST 5 digits of your VIN, then entering that integer in TEST 19. That will UNLOCK the OBC and allow you to access all of the other TESTs.

See the info below on how to UNLOCK the high instrument cluster (disregard that it says E38...all of the BMW high instrument clusters work the same way)...plus the info below gives brief descriptions of what the screens of each TEST reveal.

If you're reading this and you have the LOW INSTRUMENT CLUSTER (you have the graphic display and only one button on your cluster (left side)...click this link and scroll down to the instructions for unlocking the low instrument cluster: http://www.cardomain.com/ride/313409...series/page-6/

HINT: some of the TESTs may be slightly different depending on which BMW model you have or what BMW market you're in. For example...TEST 3 below says that the info for SI (service interval display) in the first screen will indicate "km" since the last SI reset...when many owners may see "L" (liters) of fuel consumed instead of "km" driven.

I'm not sure I understand your question thoroughly...so forgive the ramblings below if they are off course. :D

The 20 digit alpha/numeric display at the bottom center of your instrument cluster is primarily the display for the vehicles Check Control system. (If you have your owners manual...all of the warning for the check control system are listed). If there's an issue with your self leveling suspension...you will get a warning in that CCD (check control display)...it is one of the systems Priority warnings.

The OBC (onBoard CPU) can also be programmed to display all its features or only the ones you want to appear in the CCD...but again, the Check Control system has 1st priority for that screen...and if you get a warning from the CC system...it will have first dibs at the display.

Then you have the cluster TESTs which you can call up to check some of the inputs/outputs/calculations of the IKE (instrument cluster electronics)...but these are just benefits that have been discovered that were not meant for the casual BMW owner.
