Audi has issued a dealer communication regarding Service Action 93N1, which involves a software update specifically for the Audi e-tron remaining range display. This communication, dated February 14, 2024, informs dealers about revisions made to the work instructions for this service action.

Why an Accurate Range Display Matters for EV Owners

For electric vehicle (EV) owners, an accurate remaining range display is crucial for planning journeys and managing charging needs. The display provides an estimate of how far the vehicle can travel before needing a recharge. Inaccurate readings can lead to range anxiety, unexpected stops, or even being stranded, which significantly impacts the ownership experience.

EV range calculations are complex, taking into account various factors such as driving style, ambient temperature, terrain, accessory usage (like heating or air conditioning), and even battery degradation over time. A software update, like Service Action 93N1, is typically designed to refine these algorithms, leading to more precise and reliable range estimations for the driver.

What is Service Action 93N1?

Service Action 93N1 is a manufacturer-initiated campaign to update the software controlling the Audi e-tron remaining range display. While the specific technical details of the software changes are not provided in this dealer communication, the purpose is to enhance the performance or accuracy of this critical vehicle function.

This type of software update is common in modern vehicles, especially EVs, as manufacturers continually work to optimize vehicle systems and improve the user experience. It reflects Audi's commitment to maintaining the functionality and reliability of their electric models.
