New OTA Update Released for BYD Seal: What's New and How to Install

BYD Europe Service has officially announced the rollout of a new Over-The-Air (OTA) system software update for 2023 BYD Seal owners across Europe.

Delivered wirelessly straight to your vehicle without needing a workshop appointment, this new software package delivers system-wide optimizations, smoother infotainment performance, and enhanced driving refinement.

Here is a straightforward, jargon-free overview of what's new, how to install the update, and key precautions to keep in mind.

1. What's Included in This Update?

The new OTA package for the 2023 BYD Seal focuses on user convenience and core system stability:

• Smoother Infotainment (DiLink): Screen responsiveness and menu transition fluidities on the central rotating display have been significantly improved.
• Driver Assistance (ADAS) Refinement: Tuning optimizations to lane keeping and speed alert chime behaviors for a more pleasant highway cruising experience.
• Battery & Thermal Management: Software updates to the Blade Battery BMS logic for steady charge acceptance and cold-weather energy efficiency.
• Smartphone & Bluetooth Stability: Fixes for minor Bluetooth audio dropouts and improved wireless phone mirroring connection reliability.
• System Bug Fixes: Background optimizations resolving sporadic UI glitches and improving overall electronic module stability.

2. How to Check and Install the Update (Step-by-Step)

Installing the update on your BYD Seal is simple and takes just a few taps:

Method A: From the Center Touchscreen (Recommended)

1. Park your vehicle in a safe location with the gear selector in Park (P).
2. Open the main menu on the touchscreen and tap System Settings.
3. Navigate to Version > Vehicle Version.
4. Tap the Upgrade / Check for Updates button.
5. If the new package is ready for your VIN, follow the on-screen prompts to confirm installation.

Method B: Via the BYD Smartphone App

1. Open the official BYD App on your smartphone.
2. Go to More Functions.
3. Select OTA Upgrade to check if your car is scheduled for download.

3. Top 5 Precautions Before Updating

To avoid installation errors, always observe these simple safety rules:

1. Gear Must Be in Park (P): The vehicle cannot be driven during software installation.
2. Battery Charge Above 20%: We recommend at least 30% battery State of Charge before starting.
3. Do Not Charge the Car: Never initiate an update while connected to an AC wallbox or DC fast charger.
4. Unplug Aftermarket OBD Devices: Remove third-party tracking dongles or insurance transponders plugged into the OBD-II port.
5. Allow the Process to Finish: Installation typically takes between 15 and 30 minutes. The touchscreen may reboot several times; do not press the Start/Stop button until complete.

4. Don't See the Update Yet? (Staggered Batch Rollout)

BYD releases OTA updates in staggered regional batches based on Vehicle Identification Numbers (VIN).

If another Seal owner has received the update while your car still displays "Your system is up to date", do not worry. This is standard automotive OTA protocol to ensure server reliability. Your car will automatically receive an update prompt once your batch goes live.

If you believe your software is behind by several versions, you can contact BYD Europe Customer Support via the in-app chat with your VIN, or request a quick software check at your authorized BYD dealer.

Summary

Modern electric vehicles continue to improve over time through regular software releases. This latest update keeps your 2023 BYD Seal running smoothly, securely, and efficiently.
