Bordcomputer - Momentanverbrauch

[thomazzzz]

Hi alle,

ich habe eine Frage zum Bordcomputer des Z4, die mir leider auch das Handbuch beantworten kann:

Ist es möglich sich neben dem Durschnittsverbrauch auch den Momentanverbrauch des Fahrzeugs anzeigen zu lassen ?

Im Ami-Forum gibts die möglichkeit in das Onboard Diagnose Programm zu kommen. Cave: Nicht Auf Reset gehen!

Hier die englische Anleitung:

Instructions to access the hidden OBC functions:
1. Hold Trip Reset while turning ignition key to On position (this is the S/R button).
2. OBC should show "Test"
3. Use Trip Reset to select function 19.0 that unlocks all the features
3. Wait for display to show "Off"
4. Depress Trip Reset for 1/4 second and release it
5. With no delay press Trip Reset several times to select one of the following functions.
6.) To access the sub-items say for Menu item 7, stop at the item nunber and click on the S/R button. It will display 7.0 and so forth.
7.) To return to the main item i.e 5, 6,7,8 etc. Press and hold in the sub-item menu until the main item number appear. For e.g: if in 7.1 and you want to go back to 7. Press and hold S/R button in 7.1 until 7 appear. From here click on S/R to go to 8. In 8 press and hld until 8.0 appear. Click on S/r button to go to 8.1 and so forth.

I would advise not to go for Item 21, reset OBC setting. I did this and my DTC, DSC light stayed on. I got around it eventually but did scare me for a nice quarter of an hour.
Let me know if you would like the procedure.

Danke für die Info

Werde das mal am Wochenende ausprobieren.
