As some of you may know, the BMW On-Board Computer (OBC) holds more 
functions than is documented, including a very nice 
instrument panel test.
I managed to get a lot of this information from the web, but it was 
far from complete.
Subsequently I asked my dealer for the missing info, but they could
not provide the complete list either.
Following is a list for the items I could find, they work in my car 
(E46 323i). I gather most of them also work in the E36 models.
Who can tell what the missing entries represent (especially functions
9.1, 9.2 and 9.3 which are very mysterious) ?
Instructions to access the hidden OBC functions:
1. Hold Trip Reset while turning ignition key to On position
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 1/2 second and release it
5. With no delay press Trip Reset several times to select one of the
following function s

 7.0    021+   Coolent/Engine temperature (2.1C) koelvloeistof-temp.
Per chi ha voglia di fare una prova, questa e' la temperatura
dell'acqua o dell'olio motore?
Che vuol dire "koelvloeistof"?
A me sembra che si "muova" leggermente in ritardo rispetto alla
lancetta dell'acqua, quindi penso che possa essere quella dell'olio.
Pero' se fosse quella dell'olio sarebbe strano non trovare quella
dell'acqua da qualche altra parte...
Nell'elenco non ho trovato la pressione della turbina :-(((((((
