Hi, The little car indicates somthing is wrong but its not serious. Usually low water in the screen wash. If not then its a warning that some aspect of the service is due soon. Check the status from the IDrive (bottom left) and select diagnose...

Black smoke from the exhaust is an indication of the engine running too rich. Probably bad fuel injection system.

730d/2004...my key is not accepted into the holder...i have only one.what can i do?thank you


Check with your local BMW dealer. If there is supposed to be more than one key for your vehicle, they can not only tell you, but they can also cut a new key by looking up your key codes using the VIN on your car. If there is supposed to be only one key for your vehicle, they can assist you in getting any malfunctioning key cylinders repaired or replaced.

frequent problem was the water leak at the EGR on the rubber ring at the top to plastic part of the 2 screws into the AGR. This repair is easy and 5min to go!
