Volkswagen and Skoda will begin rolling out an over-the-air software update in the second half of November 2027 that adds battery preconditioning to the oldest ID.4, ID.5 and Enyaq electric crossovers on the road. The update covers vehicles built between 2020 and 2024, roughly 200,000 Enyaq models among them, and arrives years after owners first found their cars could not pre-warm the high-voltage battery before fast charging.
From 2024 onward, all three models were fitted with automatic battery preconditioning at the factory, so later cars do not need the update.
What the update changes
For the Skoda Enyaq, software version 3.9 introduces the battery pre-heating function along with an updated welcome screen that boots up fully without user confirmation. The package also includes security updates and a fix for the Online Connectivity Unit.
Volkswagen ID.4 and ID.5 owners receive the same improvements under software version 3.9.1, which additionally improves the reliability of the electric door handles and AC charging.
How preconditioning works in these cars
The feature can only be switched on manually, through a new virtual screen in the infotainment system. The heating button is active only when the battery temperature is below 20 degrees Celsius (68 degrees Fahrenheit), according to Jiri Vlcek, Skoda's project manager for online updates. The software also displays the battery's current temperature so drivers can monitor it.
Once activated, the battery heats gradually to its optimum temperature of about 25 degrees Celsius (77 degrees Fahrenheit), a process that can take 30 to 40 minutes. Both automakers recommend factoring that time into the drive to a fast charger. A battery at its optimum temperature can accept higher power from a DC fast charger, shortening the stop.
Skoda engineers tested the function in freezing conditions. Vlcek said the apparent simplicity for the user masks the work behind it: the update intervenes in the vehicle control unit, the battery control unit and the infotainment system, which he said places enormous demands on implementation and on comprehensive testing.
Rollout stages and the dealer-visit catch
The rollout will happen in waves, with the first cars receiving the feature from the second half of November and another wave following two weeks later. Owners running version 3.8 will be prompted to install the latest software automatically over the air. Cars on older software must first install version 3.8, which prepares the vehicle for the pre-heating function, before version 3.9 introduces it. Cars still running version 2.x need a visit to an authorised service centre to obtain the software that enables preconditioning.
The staged approach means owners of the earliest cars, the ones most likely to be on 2.x software, face the longest wait and a workshop appointment. That matters because those are precisely the vehicles whose owners have gone without the feature the longest.
Why owners waited, and what changes
The first ID.4 and Enyaq crossovers left the assembly lines in 2020, but their high-voltage batteries could not be preconditioned for fast charging, which produced longer-than-expected charging times in cold weather. Some owners worked around the gap with do-it-yourself methods: a custom-made microcontroller or a dedicated diagnostics dongle paired with an OBD programming app. The official update replaces those improvisations with a factory-sanctioned function.
The sources do not state how many minutes faster a DC charging stop becomes once the battery is at its optimum temperature, nor do they give a charging power figure for the pre-warmed pack. What is clear is the mechanism: a warmer battery accepts more power from a fast charger, and the car now has a button for it.
