I also get 5 beeps when I switch off the ignition. I've reset the seats, disconnected/reconnected the seat connectors, reset the seats again, and I still get the 5 beeps. My car is supposed to have a Trafficmaster TM400 Trackstar fitted which I do not subscribe to. I have tried to contact the installers of this system in order to have it removed, but they ignore me. If possible, I'd like to know where the unit might be installed in order to disconnect it myself, and thus eliminate the tracker as a possible cause of the beeps.
