    Hi, I'm the unfortunate owner of a 2006 E61 523i with a high oil consumption. The motor har been driving around 180k km. I got the car about a year ago and it has always had a very big oil consumption (1 liter per 1200km or so), which I understand from other threads is not that unusual with this...

    Hello guys! I have a Bmw 523I E39. I have a problem with no power to a player from eonon. I have a 14 pin and so does the player. When trying another player it doesn’t power on either. So that makes me think there is something wrong with the car. The fuses looked okay all 4(3 in dash and 1 over...

    Hey guys. I recently changed the entire cooling system on my e39 and noticed that the new thermostat housing that was put has a two pin plug I guess for connecting a wire to it. I'm guessing it is the thermostat housing temperature sensor. My question is, do I require to connect a wire to it(...

    Ok so it’s not mine, it’s my brothers. He has a 523i 1998. Now he is not mechanical at all and couldn’t care less about a car, or it’s mainenance. I know what a horrible person he is. Now I was looking in the engine bay yesterday and I noticed dried coolant everywhere. I didn’t know where the...

    Hi I have had my car for over 2 years. I have replaced the radiator as the last one split. That was a year and a half ago. The expansion tank never seems to have water in when cold but always seems to be ok. The issue I'm having is intermittently the car heats up (when the ac is on) I found the...

    Hello everybody, I am new to BMW and this forum, please bear with me while I explain the situation. My brother recently bought BMW 5 series 523i 2007 model, it has 60k miles on it. I don't know what was he thinking before buying it as ever since we got it I see issues after issues. We got it...

    Hey everyone I have recently purchased a turd of a Bimmer. I bought it after PCSing and the only guy to give me a call back had this 523i. It had a misfire, some surging on acceleration, and shortly after purchase the starter wouldn't disengage the flywheel. F*** me right? Anyways the misfire...

    Hello fellow BMW fans! My younger brother disconnected the trunk of my 1997 523i from the central locking system by using the key and turning it completely to the right and now I can't figure out how to reconnect the trunk to the central locking system. I've tried all sorts of things with the...

    Hi guys, First time poster here, long term lurker. I've recently attempted a pixel repair on my E39 525i, which was daunting to me, but successful. The only issue is that I believe I have somehow damaged or altered the starting position for the motor driving the fuel gauge, and now it appears...
