I checked all the wires into the seat module and everything looks secure. So I don't really think the heater element is the problem. There almost seems like there is a disconnect between the I drive control and the seat. When I set the heat to full bottom the back still gets really hot.ISTA ScreenPrints for your LIN-Bus flap control are attached. If ALL 8 Flap Motors have fault codes, then the ENTIRE LIN-Bus is likely disconnected. The 8 flap motors are wired in Series, meaning that if NO LIN-Bus connection to FIRST Flap in series (Defrost), then NO control of ANY of flap motors. If the O 2 sensor heater circuit’s negative wire goes directly to ground, look for a short-to-power problem. Usually the heater circuit in this case is controlled by a relay. Remove the relay and retest the circuit. If the light comes on again, locate the short-to-voltage in the wiring harness with the relay removed. There is only one heater core. The temperature for each side for dual climate is controlled by the blend doors. Sounds like the passenger side blend door is not working. It will take a little work to inspect it. I haven't had to do this on an e90, but have fixed two Jeep Grand Cherokee's with dual climate control.
So here's an update; I decided to try to code out my ACC module. I deleted +541 (ACC) from the VO and added +544 (DCC). I have a 6 cilinder so I need +544 instead of +540 (Regular Cruise Control) from what I understand. I then recoded the CAS, KOMBI and DSC modules.
4. Once the water pump stops after 12 minutes, open the reservoir cap (it will hiss a little) and add coolant until the measuring stick (ball indicator) is 6 mm above the top of the filler neck. (review the manual procedure for checking the coolant level so you know what I’m saying) 5.
Heated seat (Drivers) not working. In my 2009 328i, when i push the drivers side heated seat button, it lights for 1 second and then turns off. I have searched on the forums but I am not finding too much. Is there a continuity check I could perform on the seat heating element?2008 BMW e90 Had a bunch of work done recently: 1. New Radiator 2. New Aux Water Pump 3. New Thermostat Since then, I only get hot air through the vents with the heat on when NOT driving. As soon as I start to drive, the air coming through the vents with the heat on goes from Hot, to Cool, to Cold (it's 18 degrees F outside right now). 53 posts · Joined 2015. #1 · Feb 29, 2016. 2008 535i. On cold mornings the car takes a very long time (15 minutes or more) to blow warm/hot air. Checked everything in iDrive/Cimate settings, all ok. Seat and steering wheel heaters heat up very fast, btw. iTrader: ( 0) Seat Control Module Coding. Working through setting up heated seats in my car. I matched all options on seats, swapped in correct head unit, swapped seat control module and airbags in to donor seats from original seats, ran all necessary wires, and VO coded the 494 option. Then coded REM, FEM_BODY, HC2, SM2 and IHKA3 ECUs using
INPA will allow you to see a display of position of EACH of the 8 Flap Motor Positions in real time, and watch them change as Controls are operated.
