Esys is the go-to software for coding your BMW, allowing you to customize various features and unlock hidden functionalities. This guide provides a comprehensive overview of ESys, covering installation, usage, and essential tips for a successful coding experience. However, it’s crucial to understand the potential risks involved before proceeding.
Understanding the Risks of BMW Coding with ESys
Coding your BMW can void your warranty if not done correctly. There’s evidence suggesting BMW can detect coding modifications and automatically flag your car, potentially leading to issues with future warranty claims. Proceed with caution and at your own risk. Thorough research and understanding are paramount before attempting any coding changes.
Getting Started with ESys
ESys requires a launcher program to interpret the obfuscated data within the software. While EsysX and Launcher Pro are two popular options, Launcher Pro is outdated and should not be used for G series vehicles. EsysX (https://esysx.com/) is a recommended alternative.

Detailed instructions for setting up ESys can be found in Almaretto’s comprehensive guide on Bimmerfest: https://www.bimmerfest.com/threads/c…#post-10193333. This guide covers the necessary software, installation steps, and configuration process.
Coding Instructions and Resources
Once ESys is installed, refer to the coding instructions available on Bimmerfest: https://www.bimmerfest.com/forums/sh…d.php?t=983245. This resource provides detailed guidance on how to use ESys to code your BMW. While “cheat sheets” were previously used for coding, they are no longer relevant for G series vehicles due to the transition to XML format. However, for older models, you might find outdated cheat codes on Github: https://github.com/packetpilot/bmw-f/tree/master/cheats.
For G20 coding examples, refer to this Github repository: https://github.com/siegester03/bmw-g-series-coding. This repository offers practical insights and code snippets for various G20 specific modifications.
Successfully Coded Features on a G20
Several features have been successfully coded on a G20 using ESys. These include: removing legal disclaimers, enabling the M startup animation, activating ASS memory, deactivating ASD, enabling air conditioning memory, enabling video in motion, adding remote trunk closing functionality, enabling coasting, adjusting speed correction, modifying turn signal behavior, enabling lane change assistance, activating Comfort+ mode, automating heated steering wheel activation, and enabling anti-dazzle high beams.
G20 Features Requiring Manual Coding
Some G20 features lack readily available cheat codes and require manual coding. These features and their corresponding ECU properties and values are listed below:
Feature ECU Property Value

SAS2 C_SWA_VORHANDEN NR001_VORHANDENThese codes are based on the 2020.07 software version and might not be compatible with other versions. Always double-check compatibility before implementing any code.
Conclusion
ESys provides a powerful tool for customizing your BMW, but it’s crucial to proceed with caution and awareness of potential risks. Thorough research, understanding of the coding process, and careful implementation are essential for a successful and safe coding experience. Remember, coding your car could void your warranty. Always prioritize safety and responsibility when modifying your vehicle.
