Question
This is what's happening and I believe they are all related to the same source. I just do not know what to look for.

1. When the engine stops, the OBC clock time stops.
2. when I lock or unlock the car, the signal lights do not flash. However, audible sound is heard. Before, the lights would flash once when locking and flash twice when unlocking.
3. On occasion, if the trunk is chacken as a result of heavy groceries, or droping the spare tire or something, it resets, the travel tach (0.0), time (-:-pm), mileage cons1, cons2 (-/l/km). Oddly enough, the radio stations are retained and only the year in the date (00/00/2007).

I believe the wiring in the fuse box (located in the trunk) might have to do something with it. If so what wire do I check. Btw, all the visible fuses seem fine.

Can you help me? Your time and effort is much appreciated.

Regards,

Martin  

Answer
A fault such as this is a major headache to pinpoint.If things happen when you slam the trunk or do anything in the trunk then i would start there.Look at all the wires in the trunk for tightness and that they have a good earth.Not much more i can tell you about the alarm as thats a factory alarm and will have to be looked at by a tech from BMW,someone who knows this car.The electronics in this vehicle are high tech and not easily fixed as there are many computorised systems.
