I have a 1999 540i and last saterday I went to pick my brother up at his friends house,on the way there I stopped at the garage for petrol.
Turned the key and they motor simply would not start,the starter was turning and it sounded like the motor would go but then it would just drop down to zero and the engine would die.
Checked all the fuses,checked the petrol pump,the battery everything.Eventualy I had to call a tow truck to take it home.
I struggled with this car the entire weekend and eventualy the battery was flat so I just left it.
Monday I had the garage tow the car in and they put the battery on charge for a while,turned the key and the damn car starts !!! They ran a diagnostics check and could not find any errors ?
So got the car back,it runs fine and since the weekend it's been starting everytime I turn the key.
Any one have any ideas on what this might be ? Cause I realy dont feel to comfy driving anywhere cause it just might happen that I get back in the car and it wont start....
