2025 SEAL HUD unclear after windscreen replacement: check the glass and projection parts separately
Australian MY25 SEAL Premium and Performance have W-HUD. Check glass identity, equipment and repair history before diagnosing an unclear display.
After windscreen replacement on an Australian 2025 model-year SEAL, the speed display may appear less clear than before. For Premium and Performance, first check W-HUD equipment, glass identity and replacement history to avoid quoting projection-part replacement without considering the rest of the system.
Confirm the vehicle's HUD equipment first
BYD Australia's factory equipment table lists W-HUD for Premium and Performance. Explicit model-year designations in the brand dealer network cross-check MY25 identity.[Factory equipment table][U02] [MY25 version record][U03]
A glass enquiry specifying “windscreen, with W-HUD” is more useful than simply “2025 SEAL glass”. Distinguish the windscreen from front door glass as well; belonging to the glass category does not justify the same enquiry description.
The windscreen participates in HUD imaging
Pilkington's general technical explanation states that HUD imaging involves more than projection parts: windscreen optical design and installation also contribute.[General HUD technical explanation][U05] A display change appearing only after windscreen replacement therefore warrants checking glass identity and installation history together.
This gives an inspection direction, not a conclusion that ghosting after replacement necessarily means the wrong glass was fitted. An unclear display also cannot independently prove projector failure. The actual stage causing the problem still needs verification. [To be verified]
Retain a clear timeline of the change
At vehicle reception, record whether the display was clear before replacement, whether the change appeared immediately or later, whether it is mainly ghosting or a position or clarity change, and whether other displays such as the instrument panel show the same behaviour. Separate these observations rather than calling them all “screen failure”.
Procurement records can retain readable old-glass markings, replacement records and vehicle equipment. Marking photographs assist identity checks; a brand or wording alone does not complete fitment verification. Check glass and projection-related components separately before determining procurement scope.
Scope and verification
This article covers only Australian MY25 SEAL Premium and Performance, excluding Dynamic, other model years and markets. MY25 is based on an explicit version record, rather than inferred from a PDF filename.
Pilkington material explains general imaging principles only. It does not prove that Pilkington supplies SEAL or that its wedge-shaped interlayer design applies to this vehicle. No public data was available in the reviewed material for SEAL windscreen suppliers and specific optical structure, ghosting criteria, installation parameters, calibration requirements and applicable conditions, OE numbers, separate parts availability or interchangeability. [To be verified] Verify compatibility or interchangeability using the VIN and local Australian manufacturer parts catalogue.
