Salvage Title Check on a BYD: Write-Offs, Flood Damage and the VIN
A salvage title — or a write-off category, depending on the country — means an insurer decided a car wasn't worth repairing. On a BYD that matters more than on a petrol car: the battery sits under the floor, so flood or underbody damage can write off a car that looks straight, and a repaired one can hide battery problems. Here is how write-offs are recorded for BYDs in the UK, Australia and China, and how to check by VIN.
| Market | What it's called | How to check |
|---|---|---|
| United Kingdom | Write-off categories: Cat A and B (never back on the road), Cat S (structural damage, repaired), Cat N (non-structural damage, repaired) | Paid vehicle history check by registration or VIN |
| Australia | Statutory write-off (can't be re-registered) or repairable write-off (rules vary by state) | PPSR search by VIN — shows written-off and stolen status |
| USA | Salvage title, then rebuilt title after repair and inspection | Title history check — but BYDs aren't sold new in the US |
| China / export | Insurance total-loss and salvage-auction records — the branding doesn't travel with the car | Ask for the Chinese insurance and auction history; decode the VIN to confirm the build market and date |
Write-off rules differ by country and, in Australia, by state. Check the official register where you are buying.
Why write-offs matter more on a BYD
A BYD's Blade battery forms part of the floor, so a hard underbody impact or a flood can damage the most expensive part of the car without much visible damage above. Insurers often write off EVs for that reason: in one reported case in Thailand in 2023, an accident-damaged Atto 3 needed a new battery quoted at about 896,000 baht (around US$25,900) on a repair bill of roughly 1.17 million baht. A repaired write-off can look perfect and still carry pack damage.
Flood-damaged BYDs
Water in the high-voltage battery or its connectors can cause corrosion and insulation faults that show up months later — BYD's own 2025 recall of Yuan Pro cars in China was about water getting past battery seals. Look for damp or new carpets, silt under the seats, corroded seat rails and misted lights, and ask a BYD dealer for a battery health and insulation check. Flood damage is excluded from BYD's warranty.
Cat S and Cat N BYDs in the UK
A Cat S or Cat N BYD is legal to drive once repaired and roadworthy, but it is worth less and can cost more to insure. Ask for the full repair invoices and whether the work was done within BYD UK's approved repair network (around 138 sites). Pay particular attention to any battery, cooling or underbody repairs.
Written-off BYDs in Australia
A statutory write-off can never be re-registered; a repairable write-off can return to the road after repair and inspection under the rules of the state concerned. A PPSR search by VIN on the government register shows written-off and stolen status, plus any money owing — run it before you pay for any used BYD.
Imported BYDs with hidden salvage history
Damaged Chinese-market BYDs are sold at salvage auctions and some are exported. That history usually doesn't appear in UK or Australian registers. Red flags: a price far below the market, no Chinese service or insurance history, VIN plates that don't match, and repainted structural areas. Decode the VIN to confirm where and when the car was built, and get a full history report before you pay.
How to check a BYD for salvage history
Decode the VIN to confirm the model, build date and market. Run the local register check — a UK history check or an Australian PPSR search. Ask the seller for insurance-claim and repair invoices. Ask a BYD dealer to confirm the warranty status, open recalls and battery health by VIN. Then have the car inspected on a lift, with the underbody and battery casing in view.
FAQ
Can you buy a salvage-title or written-off BYD?
In many countries, yes, if it was a repairable write-off and has been repaired and re-registered. The price should reflect it, damage-related warranty claims won't be covered, and the battery deserves a dealer health check.
Does BYD's warranty cover a repaired write-off?
Damage caused by the accident or flood isn't covered. Ask a BYD dealer to check the VIN for warranty status and battery health before you buy.
How do I check if a BYD was written off in Australia?
Run a PPSR search by VIN on the government register. It shows written-off and stolen status and any money owing.
Is a Cat S BYD worse than a Cat N?
Cat S means structural damage and Cat N non-structural; both have been repaired. A Cat S car is usually discounted more, and on a BYD you should check whether the battery or underbody was involved.
Can salvage history be hidden on an imported BYD?
Yes — overseas write-offs and salvage-auction sales often don't appear in local registers. Decode the VIN, ask for the original market's history and inspect the underbody before you buy.
