Radio presets and seat memories gone and returned

[Marcoose]

Saturday, one fob battery died. New battery. Bob's your uncle. The same day, all radio presets and seat memories with both fobs were gone. Funny coincidence. Today, the radio presets and seat memories are back. Blimey. If you don't have a twisted sense of humour, BMWs aren't for you.

Action

There is no fault in the Comfort Access system. Replacement of the ID transmitter does not achieve the objective.

Technical system limitations may mean that the vehicle fails to identify the ID transmitter (remote key) under certain preconditions. Reasons for this include:

• Coverage of the ID transmitter by metallic objects.
• Frequency interference due to smartphones, mobile phones, MP3 playback devices (e.g. storing smartphones and ID transmitters together in the cup holder) which may cause interference to the transmission frequency of the ID transmitter.
• Charger in vehicle electrical system power socket
• Storing the ID transmitter in front of the instrument cluster or the display (switching frequency of the display illumination may interfere with the transmission frequency of the ID transmitter).
• Interference from pylons.
