It can be done by not starting the car turning it on an holding down the I believe the accelerator for a certain amount of time . Lots of things can cause Inpa Ista to not work . In general BMW diagnositics don't like aftermarket tunes you never mentioned Install oil level sensor into oil pan. Tighten three 10mm nuts and reconnect electrical connector. Fill engine with oil. Start engine and allow to run for 1 minute. Then inspect oil level sensor for leaks. Once you are sure no leaks are present, reinstall plastic splash shields. Upload a Photo: Choose a file. If you do NOT hear the pump running, post back immediately, and do NOT run the engine. If you have air in the system, you can get an "air lock" at the heater core. If you still have NO heat after running the Bleed Procedure, and Coolant Level is correct in Reservoir, then try "Defrost" Button on Right side of A/C Control Panel.

Its cold and wet in Seattle. Nothing crazy has happened, but the heat just doesnt work. It blows cold air. I saw online with quick search it could be the blower motor or the blower motor resistor. Not sure… it blows strong but just no heat. Just kinda weird. So has to be down to wires or something else stopping it. Could be a nearly broken wire. Enough to show voltage, but not enough to carry any current. If you measure the voltage drop on the wiring, you would probably see nearly 12V drop in the wire when trying to operate a light.
