Why is there condensation or water inside my SEAL headlights?
Light mist and a noticeable amount of water are different. The 2025 SEAL RHD handbook EN-250305 explains that moisture can condense inside ventilated lights after rain, washing or temperature changes; this alone does not establish a fault. If you have the 2026 facelift, follow its matching handbook instead.
The handbook says light fog can clear during ordinary use with the appropriate lights on. Do not make a test drive if lighting is ineffective or conditions are unsafe. A noticeable amount of water calls for attention from a BYD authorised repairer.
While parked, record which lamp is affected, whether it is mist or visible water, and whether the light works. Ask your repairer for advice before travelling if a light fails or safety is uncertain. Do not open, heat or modify the lamp to dry it.

Open source (BYD UK)How do I change the information on the SEAL driver’s display?
While parked, press the steering-wheel Instrument cluster/Back button to enter the instrument menu. In that mode, left/right selects the first-level menu on the corresponding side; roll the right-hand scroll control to browse lower-level items and press it to confirm or enter the next level. Use Instrument cluster/Back to return or exit. Outside instrument-menu mode the roller controls media volume, so changing volume instead of the display is a useful sign that you have not entered the cluster menu. These are the EN-250305 RHD handbook instructions, printed pages 64–66; use the matching handbook if your controls differ.
Should my SEAL have more than three display choices on each side?
The checked handbook describes preset instrument menus, not a freely configurable dashboard. It does not establish that every software build exposes the same number of choices. If your available choices are limited, first enter instrument-menu mode as described above and inspect the submenus while parked. Record the exact choices and full vehicle software/build before comparing another owner’s display. Do not assume a hidden menu or a later model’s layout should exist on your car.
The update screen says V1.0.0 and “latest”. Does that prove my SEAL is current?
That short label and message alone do not identify the complete installed build or show whether another car’s release applies to yours. Keep the model year/generation and a photograph of the complete software/version screen, then compare the matching SEAL release information or ask BYD to confirm your vehicle’s update eligibility. Matching released EU and UK BYD updates are owner-confirmed equivalent for the same model/generation/trim/full version; individual-car rollout timing is separate. Do not infer that a software update will cure the alarm, or install unofficial firmware to obtain extra display choices.

Your BYD. A clear next step.
Applies to: SEAL RHD EN-250305 instrument controls, printed64–66; available menu items depend on the actual model and build.
Evidence checked · Review due
Review is due. Recheck the primary source and your exact version before relying on changing details.
First useful check
While parked enter Instrument cluster/Back menu mode, then compare roller scrolling with its ordinary media-volume behaviour.
Read the result
Menu mode exposes the documented selection/confirmation controls; a limited preset list does not itself prove a fault or missing update.
Stop or change approach: Do not adjust menus while driving, install unofficial firmware or assume another generation’s options apply to this vehicle.
Prepare a useful record
Model year/generation, full software/build screen, exact visible menu choices and whether the roller controls volume or instrument selection.
Keep registration, VIN, account numbers and personal addresses out of this note. Nothing typed here is sent to us or saved automatically. Copy it before leaving the page.
Evidence and answer standard
Documented control instructions and version-identification checks; no promised extra display choices. The date records an evidence review, not a physical test of your car. A forum report can identify a question; it cannot establish a universal repair.
