A BMW i4 owner recently discovered that the electric sedan would only remotely update its software when parked on level ground. Technological advances enable vehicle manufacturers to constantly improve their products even after they leave the assembly line. With automobiles becoming more connected, many in-vehicle systems will need to be updated. These changes either fix bugs or bring new features, as seen in Rivian’s Snow Mode which increases the vehicle's reliability in winter conditions.BMW, like many carmakers, provides drivers with frequent software updates. However, i4 owner Clare Eliza realized that her EV couldn't install a new software update because the road the sedan was stationed on was too steep. The solution? The EV’s infotainment display advised her to park on level ground and try again. In a reply to the tweet, Twitter user neverpanic, who claimed to have worked with the BMW team that implemented the feature, shared what appears to be an explanation for the requirement. He revealed that it was a safety measure related to the electronic parking brake, given that the BMW could roll off a hill if the software update malfunctions. This limitation only kicks in when the incline is 7 percent or greater.
BMW Remote Software Update Requirements
In a follow-up tweet, neverpanic explains that although the parking brake shouldn't fail if the software update fails to download, “it might leave things in an inconsistent state, and this is a precaution for that state.” Having an inbuilt safety feature makes sense, but for BMW users like Eliza who live on a hill, having to park their vehicle elsewhere just to install a software update can be inconvenient.
BMW drivers can download a software update either automatically or through the BMW app. Updates take typically between 20 and 30 minutes, and they can't be interrupted once initiated. As is the case with most manufacturers, BMW vehicles can't be driven while an update is being installed. However, drivers can leave the car during the process. Installation won't commence until the driver consents using the Data Protection Menu.
It's also worth noting that if the BMW is plugged in during the installation, charging may be halted. That's why BMW advises drivers to ensure their cars are adequately charged before proceeding. Additionally, the exterior temperature needs to be above -10 °C /14 °F. The EV’s hazard warning lights and drive-ready state must also be deactivated. If a malfunction occurs, drivers should follow the prompts on the main display or the app. If it seems to be a major issue, drivers might need to contact a BMW service partner as a last recourse.
