1988 BMW 525 - Answered Questions & Fixed issues
I have a 93 525i BMW and i keep getting a warning!
On the 1990 model 525i (which should be similar), there is a float switch located at the bottom driver side of the radiator in the integrated overflow/fill tank just above the radiator drain. This float switch is what triggers the 'Low Coolant' indication on the dash. The electrical connector faces towards the rear of the radiator and has a rubber boot that protects it. To replace it, pull boot back, remove electrical connector, loosen and unscrew the retaining nut (accessible from underneath the car) and slide the old level switch out and install the new one in reverse.

Abs light stays on
you will need a scan tool to plug into the vehicle and retrieve the fault code then a diagnosis would be able to be determined, important this is done as the ABS is a safety feature. A local Auto Electrician would be able to help, or the dealership.

How do i open petrol cap on bmw 525 diesl
The petrol flap doesn't have a lever to open it like other cars but can be opened when the car is unlocked by pushing on one side of the flap to open, if this will not open then the fuel flap locking actuator is faulty and has not unlocked the fuel flap, if this has occurred open the boot and on the left hand side of the boot you will see a round button, if you cannot see this and you only see a hole then chances are the side cover has been off at some stage and the button hasn't been reinstated, if it is there, pull on it and it will pull the fuel flap locking actuator back allowing you to open the fuel flap.
Location for fuel pump on
Typically, you will find the fuel pump for a BMW 525 located under an access panel in the trunk. Remove the contents of the trunk, remove the floor/spare tire cover and a metal access panel will be visible on the floor being held in by several small bolts. The panel is about 4"x6" in size. Remove the bolts, carefully pry up the panel (it has some sticky sealing material) and the fuel pump mounted on top of the gas tank will be visible with fuel lines entering/exiting it. This is where it was for my 1990 525i.
2007 bmw series 525 code 4f97 what's this code
Hi
this could point to either low oil in your gear box, or a faulty speed sensor, if you have a oil leak on the transmission this would come up, but also if the speed sensor also on the transmission is faulty you would get this code..
hope this helps
My 2006 bmw 525i will not start all my dash board light are on help please
Test the battery with a voltmeter. Should read about 12.2 to 12.6 volts for good starting. If less then 12.2, have the battery charged and see if it comes up to 12.6. If it comes up to 12.6 and won't start, battery capacity my be diminished and may need to be replaced. Also, check tightness of cables at battery connectors. Loose is not good for starting an engine but still may operate the interior lighting..
Also if it's a stock BMW battery, I get about 5 yrs of service from them.
Bmw 525i leaks water
Have a coolant system pressure test done to find the leak if external. Have a compression test done to check for head gasket or cracked head
The radiator fan on my 2007 bmw 525i works fine
My guess is that your electric fan is NOT operating at all. Under normal conditions, just going down the highway, your cooling system will function just fine without a fan running. The air flow through the radiator is adequate to keep things cool. However, when you stop, you quickly get into an "overheat" situation. Actually, you should be able to hear your fan begin operating when your engine temperature starts climbing or your air conditioner requires the fan to do its thing. Note: If you've ever severely overheated your engine, your problems may be worse than just a fan not running, but you really do need to confirm whether your fan is operating correctly, or not. Another note: I had a vehicle with a tendency to overheat when stopped. It turned out to be a faulty (leaking) pressure cap on the cooling system.
Reverse lights not working
sounds like cable is broken in side temporary run a cable from fuse to reverse-switch.. then check out if ok run new cable from fuse to switch
Why fuel gauge not working
take the wire to the fuel sender unit at the tank and earth it out. If the gauge reads full then it is the sender unit.
Radiator fan not working
The radiator fan only comes on when the engine is at operating temperature. If it's not coming on when the engine is up to temp, check the thermostat.
2001 BMW 525i 2.5 starts and quits after two
The pressure can be good and the flow can be bad. Change the filters on the fuel line first. Then if it persists you have to check the flow. If it still is ok, you are looking at either a problem with the throttle control module or crank sensor.
