Pre-Sept E90 Software Recall for Update, You Could Get the Alarm Activation for Free
For those of you who have installed the alarm yourself in your Pre-September E90, this is your chance to get it activated for free. In the next few weeks, BMW will send out a recall letter of the software update on pre-sept e90. You can bring your car to the dealer for the software update and ask them to program your remote to get the "chirp" arm/disarm sound. You could get it for free if the service advisor's nice enough or if you promise to give him/her "5" on the service rating.
My service advisor gave me: Daylight running, Car/key memory (regconize personal profile when door unlocked), Driving-off Door Lock, Visual and Audible Alarm Arm/Disarm, Active Driveway Light (headlights stay on for 40 seconds after removing the key).
Good luck to you all.
