What a Dolphin Service Book Should List

A Dolphin maintenance plan starts in the booklet that belongs to the chassis, not in a workshop poster and not in a guessed invoice. BYD’s European and Israel limited-warranty manual, in the November 2025 edition retrieved for this article, tells the owner to maintain the car on the schedule in the Owner’s Manual and to keep software current. It also warns that coverage can fail after improper maintenance even when work was not done at a BYD authorised workshop, while still recommending authorised workshops for tools and training. That is the first-party maintenance sentence this guide will not overwrite. This article does not publish a Dolphin service price. It does not promote a 12-month or 12,500-mile interval as a global BYD factory law, even though some UK retailers repeat that pair for the wider BYD range. If the book in the car says something else, the book wins. AutoCN will help you read the book. It will not invent a menu of pounds for pads, fluid, or cabin filters.

Open the book that names this VIN

Ask for the Owner’s Manual, the warranty manual, and the stamped service record as three objects. The VIN on the plate, the VIN on the book, and the VIN on the record should match. If the seller offers a generic PDF with no chassis number, you have a brochure, not a book. Photograph the schedule pages. Photograph the last stamp, the odometer at that stamp, and the workshop stamp. A gap is a fact. A missing book is a fact. Neither is a reason to invent a full-service history.

BYD’s warranty manual used here also tells the owner that warranty service is expected in the region where the car was originally purchased from BYD. That sentence matters more than a filter brand. A Dolphin that leaves its selling region can keep its metal and lose its easy claim path. Write the selling region in the file before you write the next oil-free “EV service” slogan. Electric cars still have brake fluid, cabin filters, coolant loops, tyres, and software. They do not have a universal free-of-charge future.

Warranty lines you can quote, and lines you must not stretch

A UK BYD retailer page republishes a European-market key-parts table for Dolphin model years 2024, 2025, and 2026: bodywork anti-corrosion for 12 years with unlimited mileage; power battery for eight years or 250,000 kilometres, written as 155,350 miles, with a 70 percent state-of-health remark; drive unit for eight years or 150,000 kilometres, written as 93,750 miles; and basic coverage for six years or 150,000 kilometres, written as 93,750 miles. The same page prints a separate table for Dolphin Surf. Do not drop Surf lines onto a Dolphin hatch. Do not treat a retailer reprint as a contract until the booklet in the car shows the same numbers for that chassis. The November 2025 BYD warranty PDF is the better first-party object for Europe and Israel language. UK retail wording can still differ. Read the book that will travel with the car.

Intervals: retailer slogans versus the pages you can hold

More than one UK BYD retailer describes a typical BYD service as every 12 months or 12,500 miles, whichever comes first, and names Dolphin among the models they service. That is retailer language. It is useful as a question: “Is this the interval printed in this VIN’s book?” It is not useful as a global specification. Third-party handbook copies online often show longer check intervals for individual items, such as 24 months or 20,000 miles for several inspection rows. Those copies are not the November 2025 warranty PDF, and they are not a substitute for the book in the glovebox. If two sources disagree, stop and photograph the car’s own schedule. Do not average 12,500 and 20,000 into a homemade interval.

Time-based items are the usual trap. Retailer explainers often treat brake fluid as a two-year item and mention battery-loop coolant at a longer major-service gap. Treat those sentences as prompts. Write the fluid name, the interval printed in the book, and the last replacement date if a stamp exists. If no stamp exists, write “not shown.” A buyer who needs a cost must ask a workshop for a dated quote on that VIN. This page will not supply a pretend 2026 price list.

What a workshop visit should record on an electric hatch

Even without a price, you can specify the record. Ask the workshop to write the odometer, the date, the software version, the tyre brand and remaining depth, the brake-fluid test result or replacement, the cabin-filter condition, any high-voltage isolation test they are qualified to run, and any campaign or recall number they checked. Ask for a photograph of the charge inlet and the 12-volt battery date if visible. BYD UK’s Dolphin product page publishes V2L at 3.3 kW; if the buyer needs that function, ask the workshop to confirm the outlet still works. A failed V2L test is a condition fact. It is not a service-interval fact.

Do not let a visit become only a cabin wipe and a reset of the cluster reminder. If the cluster shows a service due message, photograph it before and after. If the book requires a reduction-gear fluid change at a stated first interval, look for that stamp. If the book is silent, do not import another model’s gearbox sentence. Dolphin is a hatch on e-Platform 3.0 in BYD UK’s product story. That architecture sentence is not a fluid interval.

Export and used cars: the book is the deal

Importers who buy a Dolphin without a book are buying a missing aftersales path. Create three rows: “European or UK booklet language,” “this VIN,” and “destination workshop.” Copy warranty years and miles only into the first row when the booklet supports them. Fill the second row from stamps and photographs. Leave the third row empty until a local workshop writes that it can service the inlet, the software, and the parts. AutoCN’s maintenance pages and parts pages are for that filing. They are not a BYD dealer, and they do not store pads for your town.

Used cars need battery language that the service book usually will not invent. A state-of-health printout, if one exists, is a separate object. The European retailer table’s 70 percent remark is a warranty threshold description, not a measurement of the pack you are holding. Do not treat a complete stamp record as a healthy pack. Do not treat a healthy-looking cluster as a complete stamp record.

Costs: how to ask without accepting a rumour

Ask three workshops the same question: “What is the dated price, for this VIN, for the next book visit, listing labour, consumables, and tax?” Compare the three answers. Throw away any answer that has no date or no VIN. Throw away any answer that only says “EV service from” without naming the book items. This article will not average those answers for you, because they do not exist on this page. A low number that omits brake fluid is not a saving. It is an incomplete quote.

Frequently Asked Questions

How often must a Dolphin be serviced?

Follow the Owner’s Manual that names the VIN, and the cluster reminder. Some UK retailers say 12 months or 12,500 miles for BYD models including Dolphin. That retailer pair is a question for the book, not a factory sentence this page will impose on every market. If the book and the poster disagree, photograph both and use the book for the contract.

What does Dolphin servicing cost in 2026?

This page does not know, and will not invent a figure. Cost is a dated workshop quote on a named chassis in a named town. Ask for the book items in the quote. A number without those items is advertising. AutoCN will not convert another country’s menu into your currency.

Does missing a stamp void the battery warranty?

BYD’s warranty manual says improper maintenance can exclude coverage and still recommends authorised workshops. Whether one missed stamp voids a pack claim is a case fact for the warranty desk, not a sentence this guide can write for every country. Keep the stamps. Keep the invoices. Do not wait for a forum story.

Can I service a Dolphin outside the selling country?

You can often find independent work. The claim path may still expect the original warranty region, as the BYD manual warns. Write that risk in the file before the car ships. A stamp from an unlisted workshop is better than no stamp only if the work matches the book. It is not automatically a successful claim.

Is Dolphin Surf the same service book?

No. Treat Surf as another nameplate. The retailer warranty table used here prints Surf on its own rows. Mixing Surf intervals or Surf cover into a Dolphin hatch file is a paperwork error. Match the cover to the badge and the VIN.

File the book, then file the quote

The Dolphin service file that can be published without fiction has a VIN-matched manual, a warranty region, a stamp gap, a software version, and an empty price cell waiting for a dated workshop quote. It may also carry a European 6-year and 8-year reprint, clearly labelled as a reprint. It does not carry a global 12,500-mile commandment, a fake 2026 price list, or a healthy-pack certificate made from silence. Keep the book in the deal. AutoCN’s information centre and contact route can help you store the photographs. They cannot stamp the next visit, and they cannot authorise a claim in a country BYD has not written down.
