Ahh, heating issues, sometimes very easy, sometimes the most difficult thing to do on a car.
There are many things that can cause your heater to not work.

Firstly, most heater issues are caused by low coolant or trapped air in the system so fill it to the rim and burp it. If its low, its going somewhere, so find it.

Next, its often the heater valve, the mixers, wiring or vac lines. (I doubt your car has vacuum controlled conditioning system though)

But, if you have narrowed it down to the core its self, first thing to do is to try to blow it out by bringing your engine to redline a few times on the highway. (First thing to do for most issues on a car, "A redline a day keeps the mechanic away") If that doesn't change anything, then its time for a flush. Set the car heat to high, unhook the core inlet and outlet hoses on the engine, then flush and backflush it a few times with a garden hose. If you have low flow, you can pour CLR in the hoses and let it sit for a few hours then flush it again.

If it hasn't had one recently, now is definitely a good time for a full coolant flush too.

Helpful tools I would recommend for the job:

Airlift ~$80 (Very helpful for burping a system)

Coolant System Pressure Tester ~$150 (Helpful for finding leaks and testing the cap)

Refractometer ~$50 (A very helpful tool, especially if you live in a cold climate. It measures the freezing point of ethylene glycol, propylene glycol and measures battery acid state)

As far as recycling the coolant, in some counties you can pour it down the drain when properly diluted, but most of the time you have to bring it in to a recycling center.

Good luck! If you have any further questions, ill be around.

One part you spray up from underneath into the drain tube with the system OFF and then let it drain out, the other part you spray into the air intake and the vents with the system running. I had to do this to my old Corolla, smelled pretty much exactly like you describe.

I'd couple that with renting an upholstery cleaner and cleaning the seats and the carpet and the rear cargo area.

Replacing a valve core should be cheap, under $50 if the shop has the tool linked below.

Most shops have a nifty tool that lets you swap core valves without dumping the system charge.

No, I just used the regular housing gasket.

Oh yeah, I had a tough time bleeding my car for some reason. I ended up using this tool to bleed it. If you have access to an air compressor, this or this cheaper one would work better. With the funnel, there's no BMW adapter, so I had to make one out of an old cap by drilling a hole with step bit.
