730d/ 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.

I have a 730D 2003 with a water leak from the agr valve from the termostat. Do you think the problem is only from this valve and if I substitute it solves it ?

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!
