2009 e70 multiple gremlins at once?

[Monza_dh]

I have a 2009 3.0 with 150k and at the same time this past weekend my parking brake malfunction light came on ,both key FOB's do not lock/open the car and all my radio button presets were wiped out.

I haven't yet been able to bring it in anywhere for codes but I am wondering if anyone else has had this happen before I rip into the brake actuator.

Maybe the battery i son the decline or the valet guy at the hotel f'd things up??

thanks in advance

Try battery first.

Looks like a related electric problem. Try to disconnect(and possibly charge) the battery overnight and check all fuses. Or change the battery and check all fuses.

Thanks will do. forgot to mention that all my presets for the drivers aids, door locks etc also went back to default settings. Things get interesting after 8yrs and 105k miles....

Agree, battery may be the issue, when starting the battery Voltage may have dipped o there may be a loose connection.
