Hi there, I am not sure that I can help but my 1992 520i did the same thing every now and then. I had the nrma come out to look at it and he said that my fuel pump relay was getting stuck on. I replaced it $42 and have not had the problem since. You might not have the same issue but it gives you something to start with.. Good luck

All the other windows work ? Not a fuse , one fuse powers all the windows . Test for B+ voltage at the switch an the window regulator would be the proper diagnostic procedure . Do you own a volt meter ? know how to read a wiring diagram ? how to do basic automotive electrical testing . The Faint click you hear is probably a relay , which means the GEM - genaric electronic modual is energizing the window relay . The windows are computer controlled .
The GEM will activate the OTD Relay until one of the following conditions is met:
The LF regulator control switch is pushed to the UP position.
The LF regulator control switch is released (OFF position) and then moved to the down position (first detent) or one touch down (OTD) position (second detent).
Seven seconds have elapsed since the OTD was initiated.
A window regulator electric drive stall condition is detected on the one touch down sense line inputs.
The UP window operation is not controlled by the GEM. The feature is activated when the delayed accessory is active and the LF window regulator control switch is pressed to the UP position. The switch provides delayed accessory power to one side of the motor and ground to the other side through the one touch down relay. The one touch down relay is not active when the LF regulator control switch is in the UP position.
Passenger windows may be raised or lowered using the LF master control switches or the appropriate passenger window switch. Passenger window switches receive power when the delayed accessory relay is active and the LF remote lock-out switch is in the UNLOCK position. When in the LOCK-OUT position, the passenger windows are deactivated.
The GEM controls manual down and auto down window movement with the down window relay. The relay is activated by applying ground directly to one side of the down window relay coil, and deactivated by removing the ground signal.
The delayed accessory relay provides power for the operation of the power windows and the power moon roof. The delayed accessory feature is active when the ignition switch is in the RUN or the ACC position, or when the ignition switch is changed from RUN or ACC to the OFF/LOCK position and the LF and RF doors are closed.
The GEM will deactivate the delayed accessory feature when:
the LF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
the RF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
10 minutes have elapsed since the ignition switch was changed from ACC or RUN to the OFF/LOCK position.
Feature inputs:
LF door open warning switch (open circuit with door closed, grounded with door ajar).
RF door open warning switch (open circuit with door closed, grounded with door ajar).
Ignition switch RUN position (battery potential on both the RUN and RUN/ACC inputs).
Ignition switch ACC position (battery potential on the RUN/ACC input).
Ignition switch OFF/LOCK position (absence of battery potential on the RUN, RUN/ACC, and START inputs).
This is a delay to power the fuel pump. You need to check the output from the ECU/ECM. check for any error codes, check if there is power from the switch. Once the engine runs , you need to see if there is any error codes or faulty symptoms.
Most modern vehicles using an electric cooling fan have a thermostatic switch that will allow them to run even after the engine is turned off.
Start and stop driving can cause heat buildup in the block which can cause problems such as the one you have and if the fan isn't bringing the excessive heat down during a stop, the hot engine can refuse to idle or accept fuel as it should.
You should listen to see if the fan is turning on after the ignition is off; this is sometimes delayed for a minute or so until the thermostatic switch adjusts to the rising block temperature and starts the fan.
If the main fan is belt-driven, it may be the AC fan that is used for this purpose.
Hello, You have a failed ignition lock cylinder, the wires that give the signal to the computer that allows the engine to start and run are broken where they leave the lock cylinder. To replace you need to remove the steering wheel, the air bag tape, the signal light switch to get to the lock cylinder. Wish I could help more.
i would expect the ATF to be lower when engine running as it is being pumped around the gearbox, as for the delay i would advise to get the OBD codes read , as this could give you a code number that will tell you what the problem is.The fluid colour sounds fine , it's when the ATF gets a dark brown colour i would advise changing. If you check the ATF again smell the fluid on the dip stick , if smells like a burnt type of smell then the ATF cooling component may not be working as well as should be,if so will require further investigation , hope this helps and gives you somewhere to start your investigations into this problem
