I had this problem too, but mine happened during real vcold weather and when it rained. The dealer replaced the sensor on one of the rear door vent windows. I have a feeling that it may be a window sensor somewhere and the cold air is causing the window to contract or flex and the sensor is picking this up in error. By the way, I emailed you sometime ago to see if you could help me get aero kits from Indo. What's up? Any possibility?
Does anybody experience that the E38 alarm system always goes off if the weather is too cold? Any fix for this?
