Steps On How To Reset BMW Computer After Battery Change

Most new car products from big brands like BMW already have built-in innovative components to help and maximize the product’s performance when it reaches consumers. 

It’s not just the engine or the controller, but even the car’s battery has significant changes thanks to the electronic management chips. 

But do we have to reset this system every time we change the battery, and how? All questions will be right in the article below.

Why Does the BMW Computer Need a Reset?

As mentioned above, next-generation systems on modern BMW models often have a separate battery management system to manage both the performance and quality.

Because positive and negative batteries will make a lot of difference to both the feeling of driving and the vehicle’s durability.

However, this manufacturer did not choose to hard-code the chip into a single battery.

Instead, with each different battery type, the computer will be able to rewrite the code to monitor this new part’s performance and discharge cycle. However, the computer cannot automatically detect the key and reprogram it, so we have to intervene.

Which BMW Models Need a Computer Reset

Of course, BMW models often do not need to be reset, and they just need to remove the battery and use it. However, you should still carefully refer to the list below to know if the type of vehicle you are using needs to be reset. Because the performance will be somewhat different depending on whether the car model you use is old or new

  • 2002 and newer 7-Series E65/E66 chassis
  • 2003 and newer 6-Series E63/E64 chassis
  • 2004 and newer 5-Series E60/E61 chassis
  • 2005 and newer X5 E53 chassis with N62 engine
  • 2006 and newer 3-Series E90/E91/E92/E93 chassis
  • 2007 and newer X5 E70 chassis
  • 2008 and newer X6 E71 chassis

Why Do New Model BMW’s Need Battery Programming And Old Ones Do Not?

It is not too difficult to understand that older BMW models do not need to reprogram the control system when changing batteries because these products are not equipped with intelligent components to help control this.

Most BMW models listed above have a reasonably new production year and

have significantly more advanced avionics than models from the 1990s and up. Thanks to that, we will see many additional tools such as transponder keys or IBS smart battery sensors appear on these models.

What Does Registering The New BMW Battery Do? 

The intelligent battery sensor, or IBS system, is a significant step forward in manufacturing and upgrading modern cars. 

Thanks to this unit, fuel consumption is no longer a painful problem when completely stopped, at the same time, reducing CO2 emissions during system operation.

IBS will analyze the battery system’s charge level and intelligently charge it only when needed. When the battery is fully charged, the engine does not need to spin the alternator, thus improving the engine’s efficiency and reducing fuel consumption at the same time.

Things To Prepare

Resetting the BMW computer after changing the battery change does not require you to do too much, so we do not need to prepare many tools like when cleaning the interior of the car. But in return, this process requires us to know the parameters to get the most reasonable choice and avoid wasting energy in vain.

  • So the first thing that you need to prepare is information about the car model and the battery and internal system. These parameters can be easily accessed through the Internet or the product documentation. The more you refer to these documents, the more accurate the accuracy.
  • The second thing to prepare is the battery because if the battery drops below the allowed level, this process will not continue anymore. And in the worst case, you will have to do the whole word again, wasting time and effort.
  • Also, do not forget to bring the key to open the car and order the vehicle to reset the internal computer system. Without the key, we will not be able to operate.
