Hello everyone,

2007 BMW 335i Convertible - I am having an issue with my central locking system. Only when using the lock/unlock button on the dash between the two vents. When I lock/unlock with the key fob. No sound. Works great!
When I push the lock/unlock button on the dash, it make a grinding/clicking sound which when i put my hand in the storage area, is the loudest and the most vibration.

It is only when I unlock it, when I lock with the button, no problem. Is there a mechanism/actuator under the storage area at the armrest area? Is there a DIY video for this fix? The door actuators are working fine, no problems there. Thank you for your help in advance. I really appreciate it.
