It cranks but does not start some times, sometimes it goes on for 10-20 secs, then next 1-2 tries it will start. Then replaced the Crankshaft sensor underneath and for 2 months it was very quick to start no problem at all, ysterday it did this no start crank several times during the day , but not today. What can it be the Cranksshaft sensor is new, the Camshaft sensors look OK. BAttery is new. Any ideas for diagnostics?
I believe have the original key, Tried to program but it didn't work. I checked the key battery and it has 3 volts. It works in the door lock, and starts the car, but the buttons for locks rear hatch and alarm do not work.
I have a 2005 BMW X5-E53. Most of the time the brake peddle is hard and works great, but every once in a while the peddle goes soft. It eventually grabs but the peddle is around 2 inches lower than usual. The person who had it before me, recently had the brakes done but they said they did not open any of the lines. Any thoughts would be appreciated.
