First post, a problem would you have guessed it. Glad I have found this forum. My whole family have BMW's so I think i'm in the right place. This isn't my car but is quite similiar, it is my currently broken down mothers car.
The car is an N reg 318Ti. She returned to the car after shopping and started it as usual. The fuel gauge shot up to full before then dropping to nothing with the fuel warning light on. She at first thought, as there was 3/4 a tank, somebody had syphoned off fuel. But on the return trip home the car also went right over to the red on temp too! She decided to continue home instead of stopping for fuel and then shut it off. The car will now do nothing, not attempt to crank at all. You cannot hear the click of a solenoid or nothing. The fuel gauge will shoot up to full, then to nothing and dance about like this every now and again.
It is hard to follow the wiring on this car but I believe the relay that could be at fault is not present on the compact version of this car.
Can anyone give a possible diagnosis to this problem. Many thanks for anyone spending the time to read this.
