If your BMW’s engine won’t start when you press the start button, you might be dealing with one of the following issues:
- inadequate key fob battery
- broken key
- Push-button start system fault
- fuel pump or relay failure
- damaged spark plugs
- faulty relays or fuses
- PCM coolant sensor or engine temperature sensor
- malfunctioning ignition coil
Your car’s inability to start could be caused by a typical electrical issue, such as:
- defective starting motor. Your engine cannot be started by a starter motor that has failed or been damaged. Try directly jumping the car if you think the starter is the issue with it not starting. If the engine still won’t start after that, you might need to buy a new starter motor, relay, module, or solenoid. The battery of the car is connected to the starter motor. A dead battery is a frequent reason for a BMW starting motor to malfunction. You could install a new battery in this situation.
- an automobile battery that is dead or discharged. You may have a drained or dead automobile battery if your key turns but your engine won’t start. Your BMW won’t start most frequently due to a dead battery. The battery won’t start the engine or power any electrical devices if it is not fully charged. To determine whether the battery is the issue, you can jump-start your vehicle. If the car starts, your battery is probably dead or your alternator is malfunctioning.
- a starting circuit problem. There can be a little issue with the connections to the car’s battery or with the starter circuit. First, inspect the solenoid. If it’s functioning, it will click as the contacts close. If it isn’t operating, there can be a problem with the wiring, the solenoid, the ignition switch, or its connections.
While some of these issues affect all BMW models, others are unique to cars with push-button start engines.
Let’s look more closely at the reasons your BMW won’t start with a push-button engine.

Your battery should be checked first because starting the car consumes a lot more energy than running the radio and lights. If your battery is original, it could be time for a replacement.
I don’t believe anyone has conclusively identified an intermittent issue that prevents some cars from starting, where the car has electricity but won’t start when the key is turned. Most people can ultimately get it to turn over after several tries, however other people claim that you can also get it to turn over by simply holding the key in the start position for a sufficient amount of time (20–30 seconds). Throughout a few weeks last summer, my 330 performed this a few times. Prior to that, I would frequently have a 1-second or less delay when turning the key. The good(?) news for me was that it simply stopped occuring after a few weeks; at the time, I was considering purchasing a beginning. It hasn’t done so since. In my search to discover what the heck was wrong, I discovered reports that were identical. There has been a lot of speculation regarding the starter, battery, and key sensor in the column (my was brand new). Consequently, if your battery is in good condition, you might try holding the start key down for a considerable amount of time; if it eventually turns over, add your name to the list.
causes of the BMW 530i not starting and solutions
Although the BMW 530i is a dependable travel companion, it is a machine with hundreds of interrelated parts, and like all machines, it occasionally fails to perform as intended. We discuss the most frequent 530i breakdown causes in this article, along with solutions.
The most frequent causes that prevent your BMW 530i from starting normally include a dead key fob battery, a dead 12 volt battery, corrosion on the battery terminals, a bad alternator, a clogged fuel filter, a broken starter, a blown fuse, an empty gas tank, an immobilizer error, or any electrical system fault.
Which Causes are Most Common?
Your BMW won’t start for a multitude of factors. The most common reasons your BMW won’t start normally include a dead key fob battery, a dead 12-volt battery, corrosion on the battery terminals, a broken alternator, a clogged filtration system, a damaged starter, an overheated fuse, an empty petrol tank, an ignition coil error, or any electrical issue.
Why won’t my BMW start despite clicking?
When trying to start your car, a loud clicking sound may indicate an issue with the electrical system. It’s possible that your battery is dead or that the alternator, which charges the battery, is malfunctioning.
The starter, a small motor powered by the battery that starts the engine, is unable to maintain power if the clicking noise is electrical in origin. Instead, it makes a clicking sound and switches on and off quickly.
Remember that in situations like this, a misfiring starter is really a symptom and not the root of the problem. Your automobile’s electrical system is probably to blame, which is why a jumpstart could briefly move your car.
Once it’s operating, have an experienced technician inspect the entire electrical system. Your alternator or battery might need to be replaced. Alternately, the issue might be resolved by simply cleaning the battery terminals of corrosion to improve the battery’s connection.
You’re not the only one having issues with your automobile battery. According to AAA, among the top three reasons members call for roadside assistance are battery issues, with the majority of those calls occurring in the summer.
With a Courtesy Check and free battery test* at Firestone Complete Auto Care, you can prevent a failed battery or an electrical problem.
No battery is included.
Why does trying to switch on my automobile merely result in a clicking sound?
The battery is typically to blame for that annoying clicking sound, and the solution may be as easy as a jump start or cable tightening. But a single click suggests that the starter motor is at blame (more on that later)
Why does nothing happen when I try to start my car?
When the ignition is turned on but no lights illuminate on the instrument panel, there is no power coming from the battery. It can be a blown main fuse, a broken ignition switch, a dead battery, or a loose battery terminal.
If the headlights come on, the battery has electricity, so the ignition switch, fuses, or wiring between the ignition switch and battery could all be at fault. The battery can be fully dead if the headlights don’t function. The battery can be charged; find out how below.
How can I tell if my BMW starter is defective?
- #1: The Engine Won’t Start.
- #2: Loud, grinding, or whirring noise.
- #3: Occasional Trouble Starting the Car.
- #4: The Starter Continues After the Start.
- #5: Smoke.
- #6: The starter engages but the engine won’t turn over.
- Seven: Battery
Why would my automobile suddenly not start?
A fading or dead battery, frayed or corroded connecting cables, a defective alternator, or a problem with the starter are the common culprits when a vehicle won’t start. It can be challenging to distinguish between a battery or alternator issue.
My automobile won’t start and has no power; why?
A broken alternator, a bad ignition switch, or bad battery connections are all potential causes of a power outage. You should examine the power sources in your car.
Why does my BMW sound like it’s clicking?
The majority of drivers get used to the sound of their BMWs. They will immediately become aware of any difference in sounds coming from their car, even if it’s only the dreaded ticking sound. Let’s examine a few causes of this noise coming from your BMW.
- Low Oil Level: The moving parts of your BMW’s engine, like the camshaft, rocker arms, and others, are maintained with special motor oil to ensure optimal performance. If your oil level is low, not all of the parts will be properly lubricated. During this time, you might hear a ticking sound.
- Even if your automobile has sufficient of oil, a bad oil pump will prevent it from getting to the top of the engine. The ticking sound may occur if the pump does not provide enough pressure for optimal lubrication, much like when the oil level is low.
- A loose lifter is a purely mechanical problem in your BMW engine that results in a ticking noise. As your engine operates, the lifter forces the intake and exhaust valves to open. The lifter will tap the camshaft and make a ticking sound if it goes loose.
Low oil levels and faulty oil pumps can be easily fixed if they are discovered in time. On the other hand, a loose lifter calls for a significant repair. If your BMW makes any of these noises, have it serviced right away by a qualified BMW mechanic.
How is a dead BMW jump-started?
the two vehicles with jumper cables. Connect one of the red clamps to the deceased vehicle’s positive (POS / +) terminal. The positive terminal on the operating vehicle should receive the other red clamp. Connect one of the black clamps to the working vehicle’s negative (NEG / -) connector.
What occurs if the battery in your BMW key dies?
You won’t be able to use keyless entry or remote unlocking if your BMW has Comfort Access if the battery in your key fob has died. You can still enter and manually start your automobile, though.
Press and hold the key release button at the remote fob’s base while unlocking the door of your car, then slide out the internal key blade. This can be used in place of a standard key to unlock your car. You can locate a little hole on the bottom of the handle if the keyhole is hidden on your car door. Use the key blade to pry off the trim panel and expose the keyhole by inserting it into the hole.
Once you’re inside, put your remote key fob in the ignition slot or, if your car doesn’t have one, press it up against the steering column’s key markings. If your key fob dies, you will still be able to start your BMW using the start/stop button on the dashboard.
If your push-button car won’t start, what should you do?
Your automobile may have a dead battery if your keyless entry system is functional but your engine won’t start. Check the battery voltage with a voltmeter to make sure that this is the issue. The battery needs more voltage to start the automobile if it has less than 12.4 volts.
My car won’t start, but the battery is fine. Why?
Your starter may be the issue if the battery appears to be in good condition. A starter is a little motor that uses battery power to pull current in order to start an engine. When you turn the key in the ignition, you can hear a clicking sound if the starter fails or malfunctions. In some cases, loose connections are the issue, while in others, a new starter may be required. There is no assurance that jumping a car will fix starter issues.
Can a BMW be jump-started?
DO NOT let any roadside assistance agency install a new battery in your BMW, and DO NOT jump start the vehicle. It might cost more than any other battery or jump start you’ve ever purchased.
If I turn the key and nothing happens, what does it mean?
A weak battery may be the cause of your car’s failure to start when you turn the key in the ignition switch. Loose battery connections and engine leaks are additional issues that could result in an engine or ignition failure. Before trying repairs, troubleshoot your car to identify the cause of the issue in order to prevent raising the stakes.
