BYD Seal U (Song Plus) Parts & OE Guide for European Workshops

The BYD Seal U is becoming a much more relevant vehicle for European workshops and parts distributors than its relatively recent arrival might suggest. According to DataForce figures, the Seal U recorded 72,667 plug-in hybrid registrations in Europe in 2025, making it the region's best-selling PHEV for the year.

As that vehicle parc grows, the aftermarket question changes from "How well is this Chinese SUV selling?" to a more practical one: how do workshops and distributors identify the correct replacement parts for it?

Hella Auto currently maintains a broad catalogue of BYD Seal U / Song Plus parts and OE references, covering suspension, steering, brakes, cooling, lighting, body and collision components, among other categories.

This guide provides a practical starting point for European buyers. The OE numbers below are reference points, not universal fitment guarantees. For final confirmation, the VIN, original part label and vehicle specification should be checked together.

Why the BYD Seal U Matters to the European Aftermarket

The Seal U completed its first full European sales year as the continent's leading plug-in hybrid, ahead of established models including the Volkswagen Tiguan and Volvo XC60.

For the independent aftermarket, registrations matter because every additional vehicle entering the parc eventually creates demand across several different repair situations: scheduled maintenance, wear, accident repair, chassis work, cooling-system service and replacement of damaged electrical or exterior components.

The Seal U is particularly interesting because its European lifecycle is not identical to its Chinese-market lifecycle. The vehicle belongs to the BYD Song Plus / SA3 family, while the European nameplate continues to have a substantial presence.

That makes accurate vehicle identification increasingly important for buyers sourcing components directly from China.

Seal U, Song Plus and SA3: What Parts Buyers Should Know

European buyers will encounter several names when researching this vehicle:

• BYD Seal U

• BYD Seal U DM-i

• BYD Song Plus

• Song Plus DM-i

• SA3

These names are closely related, but they should not be treated as proof that every component is automatically interchangeable.

Many parts belong to the same SA3 vehicle family, yet compatibility can still vary according to powertrain, production revision, destination market, steering configuration and the exact component fitted to the vehicle.

This is especially relevant in the UK, where the Seal U is sold as the DM-i plug-in hybrid. Parts information originating from a fully electric Seal U in another European market should therefore not automatically be applied to a UK DM-i vehicle.

For procurement purposes, "Seal U = Song Plus" is useful as a catalogue relationship — not as a universal fitment rule.

BYD Seal U Suspension and Steering Parts

Suspension is one of the deeper areas of our current Seal U catalogue.

Representative OE references include:

Front shock absorber-SA3EB-2905100

Control arm-SA3F-2904010A
The Seal U's chassis has attracted considerable discussion in European road tests, particularly around its soft ride calibration and light steering feel. Those comments describe vehicle tuning characteristics rather than evidence of suspension failure.

A replacement component should therefore be ordered because inspection has identified wear, damage, excessive play, leakage, accident damage or another genuine repair requirement — not simply because the vehicle has a naturally soft ride.

For suspension enquiries, workshops should provide the relevant OE reference whenever possible and specify the installation position and vehicle configuration.

Brake, Cooling and HVAC Parts

The current Seal U catalogue also includes front and rear brake components.

Representative references include:

Front brake disc-SA3HA-3501011A

Brake components should be selected according to the verified vehicle specification and workshop diagnosis. Vehicle weight or driving characteristics alone should not be used to assume premature brake wear.

Cooling and air-conditioning coverage includes components such as:

• Condenser — SA3EB-8105010

• Electric compressor assembly — SA3EB-8103020

• Compressor suction and discharge pipes

• Electronic cooling fan

• Radiator-related components

• Refrigerant hard pipes

Condenser — SA3EB-8105010

PHEV cooling and HVAC systems can contain several circuits and specification-dependent components, making the original label and VIN particularly useful when identifying less obvious pipes, compressors or cooling parts.

Lighting, Body and Collision Parts

Collision repair is another major part of Seal U sourcing.

Our catalogue includes body panels, bumper components, lamps, doors, glass and related exterior parts.

Representative lighting references include:

Headlight-SA3F-4121010B

Body and collision coverage includes products such as:

• Front and rear bumpers

• Bumper brackets and trims

• Front doors and rear doors

• Front wings / fenders

• Bonnet / hood components

• Tailgate components

• Exterior mirrors

• Door glass

• Fender liners

• Underbody and exterior trim parts

Front bumpers-SA3EA-2803111B
For lamps in particular, the vehicle side, destination market, original label and connector configuration should be checked before ordering.

For body assemblies such as doors or tailgates, buyers should also confirm exactly what is required. A complete-looking assembly does not automatically mean that glass, wiring, locks, trim, motors or other attached components are included.

How to Confirm the Correct BYD Seal U Part

An OE number is one of the best starting points for an accurate parts enquiry, but it should not always be used by itself.

For the most reliable identification, send:

1. Full VIN

2. OE number from the original component

3. Clear photo of the original part label

4. Photos of the complete part and connector or mounting points

5. Required position — front/rear and left/right

6. Powertrain or vehicle version

7. Destination country

8. Required quantity

For UK vehicles, identifying the vehicle as a Seal U DM-i is particularly important.

For lighting, steering and certain electrical or chassis components, LHD/RHD specification and production revision may also affect the correct reference.

Sourcing BYD Seal U Parts Not Listed Online

A web catalogue can never represent every reference available through an automotive supply network.

If the required BYD Seal U or Song Plus part does not appear in our current online catalogue, this does not necessarily mean it cannot be sourced.

Send us:

VIN + OE number + original-part photos + quantity + destination country

and we can use those details to check the available sourcing channels in China.

Current availability, supply type and shipping options are confirmed during the enquiry rather than assumed from historical catalogue records.

For distributors handling multiple references, an OE list or spreadsheet is also more efficient than submitting each part individually.

Frequently Asked Questions

Is the BYD Seal U the same as the BYD Song Plus?

The Seal U belongs to the same SA3 vehicle family as the BYD Song Plus and the names are closely related across different markets. However, this should not be treated as proof that every component is interchangeable. Confirm the OE number and vehicle specification before ordering.

Can I order a Seal U part using only the OE number?

Sometimes an OE reference is sufficient to identify a component, but VIN and original-part information provide a safer fitment check. This is particularly important where there are production revisions, different powertrains, left/right versions or market-specific specifications.

Are Seal U DM-i and electric-version parts interchangeable?

Not automatically. Some body or chassis components may be shared, while powertrain, cooling, electrical and other components can differ. Confirm the exact vehicle version before purchasing.

Are UK and mainland-European Seal U parts always the same?

No assumption should be made. UK vehicles are right-hand drive and the UK Seal U range is centred on the DM-i plug-in hybrid. Lighting, steering, electrical and other specification-dependent components may differ from vehicles sold elsewhere in Europe.

What should I send when requesting a BYD Seal U part?

The most useful information is the VIN, OE number, original-part label and clear product photos. Also provide the installation position, quantity and destination country. If you are unsure what the part is called, photos are often enough for us to begin checking the reference.

Need a BYD Seal U / Song Plus Part?

If you need a BYD Seal U or Song Plus part that you cannot find in the catalogue, send the VIN, OE reference and original-part photos with your enquiry. We can help identify the required SA3 reference and check the available sourcing options.
