BYD Filters and Service Parts — Six Lines, Two Kinds of Service

Service work is where a European independent workshop is most likely to lose money on a Chinese-brand car, because service pricing is habit before it is arithmetic. A receptionist trained on European brands prices a service by adding the items that always sit on a European service sheet: engine oil, oil filter, air filter, fuel filter, pollen filter, and possibly more. Apply that mental list to a battery-electric BYD and half the items do not exist on the car. Apply it to a plug-in hybrid sold in Europe as a Seal U DM-i or a Seal 6 DM-i and the engine side comes back, layered on top of everything the electric side already needs. The parts index we publish carries six lines in this category, and those six lines already contain both worlds. Read them correctly and the service menu prices itself.

1. The six lines

The first column of that table is the useful part, because it is derived from what the part is rather than from any fitment claim. A cabin air filter is needed wherever people sit inside the car, so it appears across the range. An intake air filter and a fuel filter describe air entering an engine and fuel entering an engine, so they have no counterpart on a vehicle with neither. Anything else in this category is drivetrain-dependent and must be checked against the VIN: application is confirmed per enquiry against the OE number and the VIN.

Note also what is not here. Engine oil itself, the oil filter element, brake fluid and coolant are not among these six lines. This is a thin category, thin enough that a buyer browsing it will not find a complete service sheet. If the item you need is not listed, send us the part number or a photo of the label, and we will check whether we can source it.

2. Two different service realities

Think of the workshop diary rather than the parts list, and the two shapes become obvious.

On a battery-electric BYD, the recurring service work is short in items but concentrated: filtration of the air coming into the cabin, condition and level of the coolant circuits serving the battery and the drive unit, the oil in the reduction gear unit, and brake fluid. There is no engine oil and therefore no oil filter, no intake filtration, no fuel filtration and no spark plugs. The list is short; each remaining item is unfamiliar to the price habits of a European workshop, and none of them is cheap to guess at.

On a plug-in hybrid — the DM-i range, sold in Europe under names such as Seal U DM-i — the engine work comes back on top of all of that. Engine oil and its filter join the electric-side items, intake filtration and fuel filtration become real lines, and the coolant system now has both an engine circuit and the electrical circuits to look after. It is the long list and the short list together, which is why a price built for either one alone will be wrong for this car.

The consequence for quoting is straightforward. A service price for a BYD has to be built from the powertrain, not from the badge. A second caution follows from how these cars are named in Europe: the same body shell can appear with an electric drivetrain under one designation and a plug-in hybrid drivetrain under another — the Seal U and the Seal U DM-i being the clearest example. Read the powertrain from the VIN, not from the tailgate badge.

3. Why the European service habit mis-prices these cars

Four habits account for most of the error, and none of them is about competence.

The bundle. European service menus are built around a fixed set of items that are assumed present. On a BYD the question is not "which grade of oil and which filter element" but "is there an engine at all". One VIN read settles it, and skipping it is the most expensive shortcut on the sheet.

Substitution of numbers. Even inside this small category there is duplication. Two Air Filter lines exist — 14932376-00 and 16660957-00 — and two Automatic Transmission Filter lines exist — 14099087-00 and 14442991-00. Identical English names, different numbers, no fitment column. Assuming they interchange is exactly the risk that produces a wrong part on the shelf and a second order.

The "it is just a filter" assumption. Filtration lines tend to be bought loosely elsewhere, and on this range they should not be. A cabin filter 13033895-00 that is wrong for the housing is still a return; two air filters that look similar may not serve the same airbox.

Missing items outside this category. Because six lines do not make a service sheet, the rest of it has to be sourced across the index. Ask for everything you need in one message rather than discovering each missing piece at the parts counter.

4. Building the order

Put the enquiry together as a short list, in this order. The VIN first, because it is what allows us to distinguish the electric service sheet from the plug-in one. Then each part number as printed on the label, with the -00 suffix included — in our index every BYD line is eight digits plus that suffix, and it is part of the identifier. Then a note of anything you want priced alongside, even if it lives in a different category, so both can be confirmed in one reply.

If all you have is a registration number and a description of the work, send those and we will check what can be sourced. We confirm, part number by part number, whether we can supply it. Minimum order value is €50 per shipment; guide prices are shown on the parts pages, and trade and volume pricing on request. Typical dispatch time is confirmed on the quotation; transit depends on the shipping method you choose. Service intervals, fluid capacities and any specification data are not published here — this page deals with what the six indexed lines are and how they are bought. Start from the filters and service category or the BYD-compatible parts — OE reference index, and use the enquiry page to send a list.

Short answers

Do battery-electric BYDs need engine filters? No. Intake Air Filter 14932376-00 and Fuel Filter 12407816-00 describe air and fuel going into an engine. The cabin filter 13033895-00 is needed on every car.

What makes a DM-i service different? The engine side returns. Engine oil and its filtration, intake air and fuel filtration, and an engine coolant circuit all join whatever the electric side already requires.

Why are there two air filter numbers? Because several engine configurations share one English family name and the index carries no fitment column. Treat 14932376-00 and 16660957-00 as separate, non-interchangeable lines unless we confirm otherwise against the VIN.

Do the transmission filter lines apply to electric models? Our index does not say. Both lines are listed as Automatic Transmission Filter, and whether the drivetrain in front of you is served by 14099087-00 or 14442991-00 is checked per enquiry.

Are service intervals published here? No. Intervals, capacities and specifications are not covered on this page.

Where this comes from.

The references quoted above are taken from GNSGO's own parts index for BYD vehicles — the same list at BYD-compatible parts — OE reference index. Application is confirmed per enquiry against the OE number and the VIN; the published index does not carry model-year fitment, so we do not infer it here. Model names follow the export designations listed on this page. We have not drawn on BYD's copyrighted workshop documentation, and we do not reproduce any manual or wiring-diagram pages.

This page is general information only. It is not a repair instruction, not a diagnosis of a particular vehicle, and not a substitute for professional advice. Restraint-system and high-voltage parts are outside the scope of this page. Work on high-voltage systems, restraint systems and structural repairs belongs with technicians qualified for it. Confirm the application against the VIN before ordering. Have any work carried out by a suitably qualified workshop.
