this thread is about those odd :eek: features (not everyone knows about)
of your e31.

i start with this one. press the button of the instrument cluster with the key in the ignition,
but leave the key in the turned off position. release the button and turn the key to position one and watch what happens.

that is known to all as a self-diagnostic test of the instrument cluster.

The instrument cluster test is (or should be) well known. But something I still haven't figured out is why the rpm gauge goes up to 7000 rpm on some cars, and only ~3000 rpm on others.

BMW E31 clustertest up to 7000 rpm (Youtube)

There's a thread about it at roadfly: Instrument cluster test: rpm gauge only up to 3000 (http://forums.roadfly.com/forums/bmw/bmw-8-series-e31/8630801-1.html). There are some theories about it (dependent on year, ODB error code indication,...), but I don't know what is true. I'd love to know, though...

Turning the headlights on and off again as soon as they are up several times leaves them up for cleaning after a number of cycles--3 or 4 IIRC

What do all the numbers correspond to when you do this to the instrument cluster?

I know that there are a number of functions on the OBC which you can obtain by unlocking it.

Most likely they are versions and/or revision numbers for the software and hardware being tested.

I keep my Grey Poupon in the house to keep those pesky Rolls Royce owners away.

If you ever want a real automotive challenge then think Range Rover:) The complexity of a BMW with the reliability of a Jaguar:(

Think a real off-road version of the 7 Series :)

The MKIII Range Rover (ie 2003+) is in fact based in large part on the E38.

how does one unlock the OBC?

wayneblackwell
04-18-2008, 06:01 PM
To enable the service menu, press 1000 and 10 simultaneously and execute function 19. Add the day and the month of the date shown by the OBC. For June 3rd for example that would be 6 + 3 = 9. Enter that number and press 'SET/RES'.

I don't know of any you guys don't know already.

I do have a unique feature that I'm sure u all don't have though: my left headlight pod sinks just enough every 24 hours to no longer sit flush with the hood. Every 2 days, I turn the actuator wheel 12 revolutions to get it back to being flush. A minor annoyance that is getting majorly annoying!

The service menu allows you to access all different types of info, from the battery current to the fuel left in the tank, functon 19 is the unlocking of the service menu.

No problem, this is a list of the other functions available


1.Display Test

2.Instantaneous fuel consumption in l/100 km

3.Instantaneous fuel consumption in l/h

4.Fuel consumption for calculating the range

5.Current range

6.Probably fuel left in the tank.

7.Fuel left in the tank

8.Current speed in kph

9.Probably the battery current

10.Some data????

11.Setting of country specific language and measuring systems. Select desired country setting with the 1000 and 100 keys, then. activate it with 'SET/RES'.

12.Speed to calculate time of arrival.

13.Time of arrival

14.Creation date of the ROMs

15.Some error display. Switch over from one error to another with the 1000 and 100 keys.

16.Displays data from some internal port. Choose port A to F with the 1000 and 100 keys.

18.No visible function

19.Unlocking the service menu.

At least for opening, that also works by pressing and holding the unlock button on the key fob.

I'm sure everyone knows this one. I didn't know it when I bought my 850 until it happend. I was cruising on the highway with my front windows down, I hit 100mph and my windows went up automatically.

I stand corrected. I tested today and yes my rear windows close as well. However they did not close at 92 MPH when the front windows did.

the original post had to do with using the key (all windows up), not the speed-induced closing of the windows.

The other day I tested this out again, and the rears didn't roll up just like yours didn't.

This is strange because in the past, the rears did roll up :eyecrazy

E31 is alive and full of its own unique personality! :devillook

Only front windows go up at 92 mph. I have been 130mph on the way to San Antonio from Austin on I-35, but sunroof was already closed. Almost no traffic on a short 3 lane expansion. Car was rock solid!
