Hi I have a 2009 bmw 335xi coupe. I literally replaced every components that will get this car up and going perfectly. I had to replace the alternator and the starter because all of it was super old and bad condition. Then I went and replace the battery too, so the car should be cranking right up perfectly. But when I tried to crank it, it wouldn't crank. All of the power and lights come on but it wouldn't crank. It would just go into accessory mode. Also when I step down onto the brake pedal it wouldn't really go down. It was like super firm and felt like as if something was putting pressure on it.

Could it be a blown fuse? If this happened to anyone of you guys can you please tell me how to fix it. I really don't want to tow my car to the dealership if I can absolutely avoid it.

What codes are you getting if any?

Would love to hear what you got going on. Having a no start issue myself.

brake pedal sensor - easy to verify. Have someone look at your tails when you depress the brake pedal and/or record it.

You can code around this requirement, but for safety, I can't suggest it (even though I've done it).

No brake lights - replace sensor
Brake lights - code around it and see then.

Also, the pedal will be hard, as the engine is not pulling vacuum to help out with the brake booster.
