How to Check BMW Coolant Level
BMW's low coolant warning typically comes on due to the low coolant level in the engine bay's expansion tank.
In this guide, you will learn how to jump-start a BMW vehicle with a dead battery.
It is important to follow the proper procedure when jump-starting a BMW.
A BMW is jump-started by connecting to the jump terminals in the engine bay.
Do not connect the jump box or jumper cables directly to the battery.
Watch video on how to connect jumper cables to a BMW.
If all you hear is a click, check the jump starter clamps are making good contact. Ensure the jump box is fully charged.
The battery in the car may be complety discharged. Keep the jumper cables connected for at least 15 minutes, then try again.
Common symptoms that you may experience if your BMW battery is dead.
If your BMW is over 7 years old, you are driving on borrowed time. Sooner or later, you will need to replace the battery.
You can replace a BMW battery yourself. Just make sure to perform the battery registration procedure.
Many BMW owners ask how do I get into the trunk if the battery is dead.
Use the jump-starting terminal under the hood to power up your BMW, then unlock the trunk.
These instructions work on all BMW models, including 1-series, 2-series, 3-series, 5-series, 6-series, 7-series, X1, X5, X6.
BMW engineers have made it difficult to get access to the trunk when the battery is dead.

This is a common mistake many roadside assistance technicians make.
If you read on BMW forums, you will find hundreds of cases where control modules were damaged by improperly jump-starting a BMW this way. Costing car owners thousands of dollars in repair.
Replacing the battery on a BMW is expensive because not only do you need a new battery, but it also needs to be registered.
The typical cost of a BMW battery replacement range in the $400-$500.
Before you spend hundreds on a new battery, we recommended using a trickle battery charger to bring the battery back to life instead of jump-starting the car and letting the alternator charge the battery.
By trickle charging a dead BMW battery, you have a better chance of bringing the battery back to life. Otherwise, your BMW may no longer hold a proper charge.
Use the OEM BMW Battery Charger or even the cheaper Black+Decker BBM3B 12V Battery Charger Maintainer, which works just as well.
It will take at least 24 hours to bring a completely dead battery back to life.
You are only providing 2 Amperes to the battery, which is a slow charge but ensures no damage is caused to the battery cells.
Don't leave the keys in the ignition as your BMW charges.
If your BMW keeps on dying or is not holding a proper charge, it could be due to any of the following:
