    Really stumped on this one. The aux fan only works when the A/C is on. I replaced the temp sensor on the lower radiator hose and the aux fan sensor on the shroud. I tested the fan through INPA with low/mid/high speed and it works so I know the fan is still good. I also checked the two big...

    Hi y’all! I’m about at my wits end with my car currently! I have a 2004 545i with just under 60k on the odometer. I’ve been driving it for a year and put about 15 thousand miles on it and when I first got it I had an issue where an “over heated engine” warning would appear on the idrive then...

  6. E60 / E61 (2004 - 2010)
    Hi there, My 525i E61 left me stranded on the highway yesterday. It is only 110000 km and I own it for a few months only but it already has its fair share of issues : no airbag, thermostat changed last month, rear plate light wire broken. Yesterday I was on the highway at about 130km/h on a...

After replacing the water pump and thermostat at first, thinking it was that, it kept overheating, so I replaced the radiator fan, and I came to realize that the fan just never turns on. I checked my fuses and it is related...

    My 1992 525i recently has been overheating. As i was getting close to home, temperature gauge was going up. As i reached my spot, the gauge was in the red and a very small amount of smoke (steam?) was coming from under the hood. I opened the hood, nothing jumped out immediately. Coolant was...

I took it to the dealership and it ended up being that the expansion tank had "ruptured" so i had it replaced. now the cars Low Coolant light comes on and off. At first I thought maybe they didnt bleed the system properly...

  15. General BMW Questions
    My 07 328xi overheats 50% of the time. I am not driving it anymore just to be clear. I replaced the thermostat and it still did it. Crazy thing that I can do makes me believe it’s the water pump now but I wanna make sure before I spend the $$$ on it. When it starts to overheat I open the hood...

    I have a 1998 Bmw 528i, recently I replaced the radiator since the other had a leak. Once I put in the radiator and add 50/50 colant, and test drive the car it began to overheat again after a half a mile drive. I noticed that the upper radiator hose has no coolant going through it, I checked it...

    I could use some help locating the water pump fuse. Details are: 2013 535i M-Sport, 71k miles. Wife driving home (right by the house, luckily) got the orange 'too hot, drive slowly' then 30 seconds later the red 'it's really hot, shut me down!!' display messages. I let it cool and drove it the...
