corrections to secret OBC codes

[shogun]

Kai from the German E34 board informed that these are not correct:

1. #06 is not "Amps", it's the measured current fuel in tank (in litres). Works only if ignition is on.

2. #07 is not "% of full", it's the calculated (!!) current fuel in tank.

3. #09 is the current voltage at terminal 15 (not terminal R!), so you have to turn the ignition on.

4. #10 has absolutely nothing to do with something like speedometer correction, it's for the range calibration.

Thanks for the link!

Thanks for all the info.

My 540 will not respond to a "stomp test."

Is there another way for me to find out why my check engine light keeps coming and going?

Cheers,

WOW, Built in speedo calibration!!!

I never knew one could use it to calibrate the speedo.

Does anyone have non-stock sized wheels on their e34??? Have I been missing something???? Why don't we rant and rave about this?

Heya Shogun ... so you're saying we cannot calibrate our speedo? Damn :( I wish I could do that, but thanks for the codes and corrections. Good info! :)

Can we "program" these new codes into our dash display to bring 'em up when we press the turn indicator stalk - so that they're always available? Just too lazy to try, so thought I'd ask. :p

Same Problem with the check engine and stomp test.

"Bump"

[shogun]

Australian cars do not have a possibility for a stomp test, only U.S. specification cars.
But you can do that by adding some wires. I have once posted that.
MOTRONIC to cluster and installing the bulb in the cluster. Wiring depends on the MOTRONIC, and not all years of production possible.
I only have the details for the M70 V12 MOTRONIC.

My car does not respond to the stomp test... any advice on getting error codes?

[Evan]

Does anyone have any idea of how to get the error codes from a 94 540i?

My check engine light came on this past weekend and I'd love to be able to diagnose it myself.

Best is you buy a PEAKE tool, I always have it in my glovebox
