Why does my Audi not start sometimes?
Intermittent starting issues may occasionally be associated with a malfunctioning crankshaft position sensor or a problem with the immobilizer system, neither of which may consistently activate a warning light or be readily apparent. One potential reason for your car not starting, despite cranking, could be a blown fuse for the ignition switch. You can verify this by locating the fuse in the fuse box and checking it for any signs of damage or breakage.If your engine refuses to start and your ignition continues to click over without any success, you may be able to blame it on a faulty crankshaft position sensor. Without it, your engine will have trouble knowing when to fire the spark plugs or even inject fuel, so good luck getting things started!
