Alarm messages
My two month old X3 2.0dSE Auto has been showing an array of alarm messages intermittently on the dash display, indicating that a) the Tyre Pressure Warning System is not working, b) the ABS is not working and c) the handbrake is not working - take to service immediately. After 2 visits to my main dealer he advises that I have been doing a lot of short journeys and the stop-start may have drained the battery to such an extent that the car's systems start to shut down. I find this explanation astounding as a) the stop-start should take note of battery condition anyway and b) this is tantamount to BMW telling me how to use the car. Anybody had this? Any other ideas?

See this thread which is a mix of genuine problems and red herring messages allegedly caused by low battery charge http://x3.xbimmers.com/forums/showthread.php?t=498221 My advice (assuming they did a reset and charged the battery) is to do nothing for the time being and wait and see if it comes back

Alarms
It seems to be associated with stop-start as they said. We have tried isolating the stop start, with no other changes to our driving - no alarms. Activate the stop-start and we get the alarms again. If it is due to the battery being unduly discharged then either the battery is not man enough or the start-stop control algorithms are wrong. Either way it's unacceptable at present

They've "recoded" the car and now the start/stop appears not to work at all - they have just made the problem go away rather than fixing it. Totally unsatisfactory without the start/stop which is a key part of the Efficient Dynamics thing. Waiting for further response form dealer before calling Trading Standards
