On the E46, it is normally a case of replacing the (electric)
thermostat.

Good luck.

Yes of course. From memory, the thermostat has a heater in it to
enable the car cooling system to reach it's optimum temperature
faster.

When I saw the same (or similar) fault code, I assumed it was Manifold
Air Pressure, but I dug deeper (in Bentley - where there is a circuit
diagram - and talking to the local indy) to find it was the
thermostat, however I never found what MAP stood for! If you look
here - http://www.realoem.com/bmw/showparts.do?model=BN52&mospid=47620&btnr=11_2180&hg=
11&fg=35
- you will see the electrical connector for the thermostat.

In any case, I replaced my thermostat, after first checking the
electrical connector, and it got rid of the fault code. The car warms
up faster now, but I dont notice any other difference.
