Okay, so I press 1000 and 10 simultaneously and it reads "Funktion: -- --" . I then enter 10 for land and press set/res and the readout goes black and accepts no further numbers.
Same thing with the unlock sequence. After pressing 1000 and 10 I get "Funktion: -- - -" and enter 19 and press set/res. After that the readout goes black. When I start the car I get "kühlwasser prüfen -- betriebsan leitung" which translates "Check cooling water -- OPERATING INSTRUCTIONS"
Again, this is the 11 button version, NOT the OBC as described in Bentley's, instead it is called "check control/ambient temperature/clock". There seems to be no other mention of it in that overpriced &^&%^$ book.
Are you aware of manuals for the four different versions of this computer found in the e36?
Thank you very much for your help!
