Regarding gas smell in cabin.

While it could be any one of your injectors it is most likely the cold start
injector - for some reason they develop a leak around the top.

Other spots to check are all the fuel hose connections in the engine
compartment - to the  injector rail and also to that cold start injector -
probably time to replace those hoses, or at least the ends of them an put on
new clamps.

Other area to check is the gas hoses from the tank to the fuel pump and
filter (under the rear of the car) if they are spongy or there is any hint
of leaking change those also.


Regarding you heater being on - probably the hot water control valve - on
the firwall in the engine compartment. the valve unit in it has a rubber
diaphragm that fails - 4 screws on top and it pulls out - get a replacement
at a BMW shop - about 20-30 dollars.
