    A common issue with E71 X6M-S63 V8 motors is that they run pretty hot due to the design of the motor and where the turbos are placed within the cylinder banks. Which is known as a hot V, by removing the plastic engine bay cover from the top of the engine you allow heat to dissipate away from...

    Hey everyone, 2002 530I Set temps to 90, and three red dots, no heat. So I replaced the thermostat (and the water pump since I was there), no change. Next I replaced the heater control valve, I did check to make sure that water was going to the valve, still no heat in the car. Don't have any...
  4. G20 (2019 - Current)
    My G20 first presented this problem 10 months ago: when I leave it parked in the sun, on a hot day, the keys will not open the car, neither make it startup. I have to use the physical key (by removing the cap on the door handle) and starting the car with the near the steering wheel. The mobile...

  7. E39 (1997 - 2003)
    I apologize in advance if someone has already made a thread about this, but I could not find anything that would fix my issue. A while ago in the summer, my fans were only blowing heat, and I could not change the speed of the fans, turn them off, or change the temperature. Eventually, the...
  8. E46 (1999 - 2006)
    Hey guys, I have had a strange issue with the heated seats in my E46 (2002) since I picked it up a year ago. On both the driver and passenger sides, the seats will only heat on the low setting (green light, rocker switch in the down position). When I put either side on high heat (red light...
  9. F30 / F31 / F32 / F33 / F34 / F36 (2012 - current)
    So, I recently noticed that my BMW after 30+ minutes of driving the heat, no matter if I have the temperature set to it’s lowest (60), is letting warm air into the cabin. I have to turn the AC on to cool it down even though it’s a comfortable 56 degrees F. Anyone know why this might be the...
  10. E63 / E64 6 Series (2004 - 2010)
    My 2010 650i and the blower for heat/AC only works on occasionally. When it does work it works great. I assume it is either the final stage or a bad/ gummed up blower? can someone please get me instructions on how to replace the blower motor and final stage? found nothing online and I refuse to...

    EKP + CPU Fan = Cool Wife has a 2010 535i, was getting a random shutdown while driving with a fuel pump error. Car could restart after a few minutes and drove fine until a few days later it would shutdown. Replaced the Low Pressure Fuel Pump LPFP in the fuel tank, but still had the issue...
  12. X5 F15 (2014 - 2018)
    I have both a 2018 X5 and a 2017 i3. The i3s airconditioning works great. Set the desired temperature and it works hard to make it happen. The X5s is another story. It almost seems that the system is lethargic in both heat and cool cycles. You can change the desired temperature setting, and...

    Team, (2009 BMW X5 35D.) Problem: The front blower for both heat and AC is not working at all. It slowly had gotten worse with blowing then quit altogether.

  14. X5 E70 (2007 - 2013)
    Hey everyone. I have a 2008 X5 4.8i E70. When heat is turned on it will blow hot on the passenger side and cold on the driver's side face and foot vents. This remains constant. The cold air coming from the driver's side seems to be whatever the outside temperature is (not confirmed). A/C...

  16. X5 E53 (1999 - 2006)
    I was adjusting my heat a couple of days ago and the entire climate control panel shut off. I check what I thought were the fuses, based on the fuse panel description, but they all looked good. I also noticed one light was still on, but everything else dark/blank/not working. I order a used...
  17. X3 F25 (2011 - 2017)
    Hi everyone, I have a 2015 F25 and am utterly puzzled about the "residual heat" feature - or lack thereof. The owner's manual - page 155 of the "Online Edition for Part no. 01 40 2 960 386 - II/15It" to be exact - clearly labels the fan buttons as "Air flow, residual heat." However, I...
