I cannot start the car at all. I think that the battery is not the cause as all electrical components in the car are working properly. Both the outside and inside lights work. I tried to jump the car but it's unresponsive. The issue occurred out of the blue and I've never had any problems before. Do you have any idea what could be causing this? Show Recommended Services
Hey there, thanks for writing in about your 2008 BMW 535xi. A no crank, no start condition indicates a problem with the starting system. This could be the starter itself or the starting circuit. In your vehicle, power to the starter is directly controlled by the car access system module. This module decides when to activate the starter based on inputs from the transmission module (clutch module of you have a manual), start button and different parts of the anti-theft system. If power is not getting to the starter, it’s likely because the module is not receiving a proper signal from one of these items. If you’d like to have this checked, I recommend you have a professional, such as one from YourMechanic, inspect the starting problem firsthand and perform the correct repairs.

Why is my car cranking but not starting?If the car cranks when you turn the key, but the engine won't start, it could be because fuel isn't getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
Can a fuse cause a BMW not to start?Check Fuses / Relays
Your BMW may not start due to a blown a fuse or a bad relay. Checking the fuses on a BMW is very easy. You can remove the fuse and visually inspect fuses. You can also check with a digital multimeter.
Why is my BMW clicking but not starting?It might be a battery or alternator problem.
Perhaps your battery's dead, or your alternator, which charges the battery, isn't working correctly. If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn't have enough juice to stay powered.
