The Check Control in the instrument cluster of the current BMW 5/7series hides somes secrets. Here is the procedure how to unveil them and how to unlock the system to get access to all tests:

Turn ignition to pos. II
Push right button in the instrument cluster and keep it pushed. You will first see "Check Control OK", some seconds later you will see "Test Nr.01"
Push the left button on the instrument cluster to see the car's identification number. Add the 5 digits together and write down that number, you will need it for unlocking all the functions. Example: DG23278 will lead to 2+3+2+7+8 = 22
Push the right button until you see "Test Nr.19"
Push left button until you see the number that is equal to the one you calculated above
Push right button again
Now you will have unrestricted access to Test No.3-21. If you made an error in the procedure mentioned above, Test No.3-21 will only display Lock:ON
