I have been looking into what normal functions for this car should be and I've found a couple things that may be corrected by a dealer, but I'm not 100% sure. The first is the alarm, specifically the lights on the car when it's armed. On every car I've ever had with a factory alarm, arming it flashes the lights and also may sound the horn. It does not do this on my 330i. When I press lock on the key, I hear the doors lock, and the interior lights shut off, but there's nothing going on with the exterior lights or horn. Same when I unlock it. One touch unlocks the driver door, 2 opens the other doors, but no lights on the outside. I found this thread on e46: http://forum.e46fanatics.com/showthread.php?t=807290 that says a dealer should be able to change this setting, can anyone confirm? By reflash, I assume they mean a software update or a return to factory default.
The second problem isn't really a problem but a setting with the door locks. Driving over 8mph locks all the doors. This is getting annoying, as I have to manually unlock the doors every time I get out of the car and need to open the back door. The owner's manual says this can be changed at a dealer. Does anyone know if they charge for something like this? Has anyone had to have this changed?
The last is the heater. I'm in FL, so heating isn't really a concern but for a month or 2 out of the year. I turned the heat on the other day to test it out, and it does work fine, but seconds after I turn it on the low coolant light comes on. If I turn the heater off, seconds later the low coolant light goes back off. The light remains on as long as the heat is on. From what I gather, it seems like when the fluid goes to the heater, it must drop just below the limit to set off the light, and when the heater goes off, the fluid returns.
Anything thoughts on these?
