With the key in the "Radio" position (Radio and OBC light up, but not the instrument cluster), press the "CODE" button. Then push the little reset-hole with a Pen and hold it, 'till the computer blinks in the display, and it will ask you for a time and date entry. - You now have re-adapted the coding plug to the computer. - Normally the computer goes into a PPPP mode when the car has been boosted, or some other very drastically voltage changes have occurred.

I had to reset the clock, etc. on the on board computer in my '85 528e. The display for the temperature and a few other items is showing "PPPP". Anyone know what causes this and how to correct it?
