iTrader: ( 0) Replacing the Radiator/Heater Core Already? Hi folks, Recently picked up a CPO 2015 328i GT xDrive (~17,500 mi) about a month ago and when it started getting a little colder here in CT (last week), noticed that the heat on the passenger side was never really hot, in fact even when set to 84F the highest setting it was usually cold.
DEFA and BMW Canada Preheater Systems. The $695 installed plug in unit charges battery, heats interior and heats probably coolant rather than oil ( oil would be better). Cheaper if car already has an installed DEFA charger ( I assume for battery). Norwegian DEFA has many diverse heating products. The video shows iPhone/android remote applications.
Battery condition and other consumer loads can mean the heated rear screen (high load) can be 'clocked' to a reduced output by energy management. I've had this before, in my E91, worked fine once other electrical loads were switched off. Tried using my rear window defroster last night and it wasn't working.
Staff member. Oct 29, 2018. #2. Yep. common E90 issue. Something must be loose. Open you boot and give the inside of the trunk (the board) a slight knock. See if the light comes on (even just for a short span of time). You may need to solder the connection (if you're not willing to buy a new light). If you have subwoofers in the boot then that
to fix, turn the AC off, recirc the air, and change to manual high. anything to get the ice to melt. f30 has a tsb out, noting for the f22/23 as I know of. not sure what the tsb says either. You can also take it to the dealer as Scadam mentioned, and apparently they have a software fix to keep from freezing the sensor.

One way to check it is to remove the mirror glass (by grabbing the outer edge with fingers and pulling it) and look at the back side of it - heated ones should have wires
