  2. X5 F15 (2014 - 2018)
    I purchased this vehicle back in October and recently had the check engine light come on. The vehicle has not been in any accidents and there were no significant event or parts replaced recently. I hooked up my scanner and ran the diag and came up with a few codes. 140001-Misfire, several...
  3. E60 / E61 (2004 - 2010)
    Hi, recently I have noticed that my BMW is using a lot of diesel. The engine temperature is 70-75 which to my knowledge should be around 90-95. So this could be my thermostat? When driving very carefully on the highway I can get it to 7l/100km but when driving in the city it takes always over...
  4. F10 / F11 (2011 - 2016)
    Hi. I have a 2013 F11 520d N47 and the lower radiator pipe remains cool to the touch even though the temperature guage reads 100 degrees and the top pipe is hot to the touch. The fan also runs even with the lower pipe not being very hot. Also not much heat coming from the heater matrix Could the...
  5. X1 E84 (2011 - 2015)
    Hi Guys, the vehicle only has around 46k. Noticed a slight loss of power under hard acceleration, also noticed the cooling fan running full speed at certain times. Then the CEL illuminated with P0128. The weather has recently cooled off here in the northeast. I noticed the heat did not seem as...
  6. E90/E91/E92/E93 (2006 - 2013)
    Good time of the day guys, Got E92 325i manual and driving it around in UK (did 121k miles so far). After ~100 miles drive recently noticed that there is no hot air coming from the air vents (outside temp was around 5 degrees C according to the cluster). After some more diagnosis, realised that...
  7. General BMW Questions
    Hi All, Did some maintenance work and replaced AC Compressor, Water Pump, Thermos, pulley kit, belt etc… Where do you guys dispose of the AC, Water Pump, Thermo? I got everything from FCP and ECS and there was no Core exchange. I asked my Indy mech if he’d take cause since held pressurizing my...
  8. E90/E91/E92/E93 (2006 - 2013)
    Hi. I'm new to this forum and I'm also frustrated with and tired of trying to get my issue sorted. It's been haunting me for almost 2 years now. The heater on the driver side doesn't seem to work properly - especially through the footwell and very right hand side vents. I have an e90i 2007...

    Hi guys and gals I have an issue with my Thermostat, the problem is that it doesn't open, the car doesn't over heat I have changed the rad to an upgraded rad which is a performance rad which doesn't have the plastic on the side as every year my rad starts leaking on the top corner which I was a...
  10. E63 / E64 6 Series (2004 - 2010)
    While replacing the upper coolant hose on a 2005 645Ci (6 speed manual), I ran into a little problem with one of the smaller hoses in that assembly. The longer of the two smaller hoses that runs from the water pump connection to something at the bottom of the radiator is difficult to pull the...
  11. E60 / E61 (2004 - 2010)
    I recently purchased a brand new Borg Warner OEM replacement for my 2007 550i from FCPEuro.com after realizing i needed to replace the water pump and water pump pulley. On my way to work a few days ago the upper coolant hose had so much pressure it popped and so i replaced that. today i ran...

    I have a 2011 335i sport package with the n55 I change both the pump and thermostat. How ever my system wouldn’t self. Bleed the car it ran fine then the next day over heated found it was the thermostat circuit open. Just put a new thermostat in and still no self bleeding car started fluids...

  14. E39 (1997 - 2003)
    I’ve got a 2002 540i with 90k miles on it. Let it idle in the driveway to warm up while waiting to go somewhere, and it overheated, the needle went as far right as is possible. Has never done this before. No coolant on the ground anywhere. I opened the expansion tank, and there was no pressure...
  15. X3 E83 (2004 - 2010)
    Hi. I successfully replaced the cracked Expansion Tank last week but when I took it out, I realized that the thermostat was cracked/broken to, but since I didnt have a replacement for it, I installed only the tank. Did all the process of bleeding the system and everything looks good, no alerts...
  16. E60 / E61 (2004 - 2010)
    Hi, all. Time to give back, here, as these forums have always been so helpful. The repair: water pump and thermostat replacement on an AWD E60/N52 5-series (2007 530xi). I think this procedure is similar for E60 and E90 models with either N52 or N54 engines. Regardless, the procedure is quite...
  17. 5 Series
    Hello! I recently changed both my thermostats since it was not getting warm enough. When I did this, i poured in(what i thought was 100%) coolant. Everything worked fine. Temps in the 90's and stationary 97, then it opened up en cooled it back to 92. Driving to 90 and so on. Also on highway and...
  18. E39 M5 (1998-2003)
    Hey guys, This forum seems very slow but FWIW I made a video replacing the thermostat a while ago and figured I would post it. Hope it helps someone! It wasn't as bad as it sounds... Just get the thermostat housing cover and save yourself the hassle of pulling the old gasket etc... It was like...
  19. X5 E70 (2007 - 2013)
    This is not a step by step. Sorry for those looking for one....if needed email me at [email protected] for one if needed..... That said, did this job tonight. Couple of things: Get to the thermostat and pump from the bottom. Use jack stands etc. or a lift. Make sure you have a 1/4 inch...

    I have searched but cannot find a thread that solves my problems without throwing money at it. Backstory: Replaced radiator with a cheap aftermarket one last fall because the old one was leaking. Was find until about last month when it started popping hoses off. 4 times total, 3/4 were right...
