Car crank on 2nd turn

[crusher]

I have a weird "problem". Scenario like this.Each morning I go to work at 7:30 AM, car starts easily. Reach office at 8:30 AM park car at basement. Time to go home at 6:30 PM. Car will not crank (usually) on first turn but always starts up on 2nd turn.Is it my battery needs replacement? but then why only happens at my office basement????

I have been facing a similar situation as you on my E32 for the past year or so... easy crank in the mornings, but slightly longer when the engine's warm/hot, or after being parked for some time. But so far never faced the need to crank twice though for the car to start, just that needed to crank the key for a wee bit longer before engine finally starts...

bro,

Last time I had the same problem. since I've got a bit know how on engine, I changed the thermostat. Found out that the thermostat locked on 'hot' position and somehow BMW ECU got a safeguarding or fail safe system some may say to cut off the power to starter solenoid when this happened just to ensure we won't overheat our engine. My symptoms were:

Engine temperature were slightly off than usual reads while running
Engine oil slowly over the period coming down, sign of vent or relief valve open during high temp
While car can't be crank, tried to pour some water on the thermostat's housing, tried cranked and engine started. Means thermostat seated after cooled down.

Well, this is just my experience. Dunno how Sifus here experience.

Adieu

does it have like a "whirrr" sounds when it refused to start ? had that problem on my E46 . it was the starter module . had then replaced the starter switch & starter gears .
no issue until now .
