Body - Trunk Opens By Itself
SI B 61 01 06General Electrical Systems

Technical Service
SUBJECT
Trunk Opens without Request
MODEL
E90 (3 Series)
SITUATION
The typical customer complaint is that "Trunk open" warning shows on drive-away, but the customer did not press the "trunk-open" button. There are no relevant faults set in fault memory.
CAUSE
The "trunk-open" button on the key was inadvertently pressed when the key was removed after the last drive cycle.
The key is positioned in the key holder with the buttons uppermost.
When removing the key, the thumb often falls on top of the trunk-open button, and depending on how hard and how long the key is grasped, the trunk may be unlatched. However, the driver is only made aware of the condition after the next engine start - the trunk- open warning shows once the wheels start turning.
CORRECTION
Please advise the customer of the key issue and suggest that to avoid the situation, to hold the key differently or insert it upside down.
