Symptom Finder: Known Weak Points
| What you see or hear | Check first |
|---|---|
| Parking sensor or driver-assistance warning after a minor knock | The sensors in the bumpers and their brackets. A bent bracket can trigger the warning on its own, so check it first, then order the sensor by the OE number on the old unit. |
| Engine warning light | Start with the lambda and emission sensors and the intake hoses on the 1.5-litre turbocharged engine. Every version uses the same engine, but still match each sensor by OE number. |
| Coolant warning or a falling coolant level | Coolant hoses, the expansion tank and the temperature sensors. The car cools an engine, one or two motors and a battery, so trace the leak to its circuit before ordering. |
| Knock or clunk from the front over bumps | The front double-wishbone control arms, their bushes and ball joints. They carry up to 2,670 kg, so inspect both sides and order by side. |
| Unsettled ride or a damping warning | The dampers. They depend on the version, so confirm the drive layout and match the damper by OE number. |
| Brake judder, squeal or uneven pedal feel | Pads and the ventilated discs, front and rear. The all-wheel-drive cars are heavier, so check the disc on the car and match pads and discs by OE number. |
| A new tyre does not match the others | The Tang L DM runs 255/50 R20 or 265/45 R21, the same size front and rear. Read the sidewall and order to that size. |

About BYD Tang L DM Parts
The BYD Tang L DM is the plug-in hybrid version of the Tang L. It is a seven-seat SUV that launched in China on 9 April 2025. The body is 5,040 mm long on a 2,950 mm wheelbase, and every version pairs a 1.5-litre turbocharged petrol engine with a 200 kW front motor. The DM-i is front-wheel drive. The DM-p adds a 200 kW rear motor for all-wheel drive. That mix means the car needs two kinds of parts. It has the oil, filters, fuel and emission hardware of a petrol engine, and the motors, battery, cooling and body electronics of an electric car. Most body panels are common across the range, while the rear drive, dampers, wheels and battery depend on the version. Every part on this page is listed by its OE number, and that number is the surest way to confirm a part fits.
What to know before buying BYD Tang L DM parts
Start by making sure the car is a Tang L and not the older Tang. The two share a name and a family look, but the Tang L is the larger car. It measures 5,040 mm long, 1,996 mm wide and 1,760 mm tall on a 2,950 mm wheelbase, while the 2026 Tang DM-i has a 2,820 mm wheelbase. A tape measure between the wheel centres settles it. Panels, glass, lamps and suspension parts do not cross between the two. The Tang L EV is the other close relative. It shares the body but has no engine, so fuel, exhaust and engine parts apply only to the DM, and the high-voltage hardware of the two cars is different.
Next, settle the drive layout. The DM-i is front-wheel drive, with one 200 kW motor at the front. The DM-p adds a 200 kW rear motor for all-wheel drive, so it carries a rear drive unit and rear drive shafts that the DM-i does not have. The extra hardware shows in the weight. Chinese kerb weights run from 2,400 kg for the DM-i to 2,570 kg for the 200 km DM-p and 2,670 kg for the Drone Enthusiast Edition.
Wheel size follows the version, not the trim name. In China the DM-i and the 200 km DM-p are listed on 255/50 R20, and the Drone Enthusiast Edition on 265/45 R21. No spare wheel is carried, so read the sidewall before ordering tyres or rims.
Every Chinese Tang L DM carries a 35.6 kWh Blade battery. Some export cars use a smaller pack, so match battery, charging and pack cooling parts by OE number, never by name.
A few things vary from car to car. The Drone Enthusiast Edition has a roof pod that raises its height to 1,970 mm, and it is the only Chinese version listed with a tow hitch. Flagship trims carry a roof-mounted lidar, and the parking sensors sit in the bumpers, so a bumper repair often needs sensors and brackets as well as the panel. For painted panels, order by the colour code on the car. The engine is the simplest area to order for, since every version uses the same 1.5-litre turbocharged unit.
Before You Order: 8 Checks
- If you are unsure whether the car is a Tang L or the older Tang DM-i, measure the wheelbase. 2,950 mm is the Tang L and 2,820 mm is the 2026 Tang DM-i.
- Look under the rear of the car for a rear drive unit, then order rear drive and damper parts to suit front-wheel or all-wheel drive.
- Match the OE number on the part you are replacing to the OE number on the listing. A matching number is the surest check that a part fits.
- Every Chinese Tang L DM carries a 35.6 kWh battery, so match battery and charging parts by the OE number on the part you are replacing.
- Read the tyre size on the sidewall before ordering tyres or rims, since the car runs 255/50 R20 or 265/45 R21 depending on version.
- Order painted panels by the colour code on the car rather than by colour name.
- On a Drone Enthusiast Edition, order roof pod parts by OE number, since no other version shares the pod.
- Read the build date on the identification plate before ordering lamps, bumpers or door handles, so you are ready when the updated car reaches the road.
Generations and Facelifts
The Tang L is the larger member of BYD's Tang family. The Tang DM-i is still sold alongside it as a smaller seven-seater on a 2,820 mm wheelbase, and the two do not share body or suspension parts. The Tang L was unveiled on 16 January 2025 and opened for pre-orders on 17 March 2025. It launched on 9 April 2025 in two forms, the plug-in hybrid DM and the fully electric EV. The DM came in three versions: the front-drive DM-i with 215 km of electric range, the all-wheel-drive DM-p with 200 km, and the DM-p Drone Enthusiast Edition with 175 km, a roof pod and 21 inch wheels.
Outside China the car is also sold as the Sealion 8 or the Atto 8 in some markets. Some export versions differ in battery and engine output, so match battery parts and engine parts by OE number rather than by name.
In 2026 BYD added the Great Tang above the Tang L. It is a larger SUV with a 3,130 mm wheelbase and a separate car for parts. In July 2026, reports from China showed an updated Tang L with a new front light bar, reworked rear lights, flush door handles and new wheel designs. At the end of September 2026 no facelift had gone on sale in any source we found, so panels, lamps and bumpers have not changed since launch. Once the updated car arrives, read the build date on the identification plate before ordering lamps, bumpers, door handles or wheels.
BYD Tang L DM Parts: Frequently Asked Questions
How do I make sure a part fits my Tang L DM?
Match the OE number. Every part on this site is listed under the OE number printed on the original part, and if the number on the part you are replacing matches the listing, the part fits. This check matters on the Tang L DM because the same body comes with front-wheel or all-wheel drive and different wheels and dampers. If the old part is missing or its number cannot be read, send the details through the quote form with a photo and we will reply within 24 hours, usually sooner.
How can I tell a Tang L from the older Tang DM-i?
Measure the wheelbase, which is the distance between the front and rear wheel centres. The Tang L measures 2,950 mm and the 2026 Tang DM-i measures 2,820 mm. The Tang L is also longer and wider, at 5,040 mm by 1,996 mm. The two cars share a name and a similar look but use different bodies, so panels, glass, lamps and suspension parts do not cross between them. Once you are sure which car you have, confirm each part by its OE number.
Do Tang L EV parts fit the Tang L DM?
Some do and many do not. The two cars share the same 5,040 mm body and 2,950 mm wheelbase, so some panels, glass and trim may be common. The EV has no engine, so fuel, exhaust, engine cooling and oil parts do not apply to it. Its motors, battery and high-voltage parts are its own. A shared look is only a starting point. Before ordering anything from EV listings, compare the OE number on the part you are replacing with the number on the listing.
Is the Sealion 8 or the Atto 8 the same car?
In most markets, yes. Outside China the Tang L DM is also sold as the Sealion 8 or the Atto 8 in some markets. The body and dimensions are the same, but the specification is not always identical, since the export front-drive car carries a smaller battery than the Chinese one. Confirm which car you have, then match parts by OE number.
Which battery does the Tang L DM use?
Every Tang L DM built for China carries a 35.6 kWh Blade battery, whether it is the front-drive DM-i or the all-wheel-drive DM-p. Some export cars use a smaller pack, so a battery from a car first sold outside China may not fit, and charging and cooling parts around the pack may differ too. Read the OE number on the pack or part you are replacing and order to that number.
How do I tell a front-drive Tang L DM from an all-wheel-drive one?
Look under the back of the car. The DM-i is front-wheel drive, with a single 200 kW motor at the front, and it has no rear drive unit or rear drive shafts. The DM-p adds a second 200 kW motor at the rear for all-wheel drive. Chinese kerb weights run from 2,400 kg for the DM-i to 2,670 kg for the Drone Enthusiast Edition. Rear drive parts belong to the all-wheel-drive cars only, and the dampers differ between the two, so settle the layout before you order.
What tyre sizes does the Tang L DM use?
Two sizes are listed, 255/50 R20 and 265/45 R21, and each car runs the same size front and rear. In China the front-drive DM-i and the 200 km DM-p are listed on 255/50 R20, and the Drone Enthusiast Edition on 265/45 R21. The size depends on version, so read the sidewall of the tyres already fitted and match the rims at the same time.
Does the Tang L DM carry a spare wheel?
No spare wheel is listed for any Chinese version of the Tang L DM. After a puncture that cannot be repaired, the tyre or wheel has to be replaced, and it needs to match the size already fitted, either 255/50 R20 or 265/45 R21. Wheel size follows the version rather than the trim name, so read the size on the sidewall before you order. Order a replacement rim by the OE number on the old wheel wherever you can find it.
It is a plug-in hybrid. Does it still need oil and filters?
Yes. Every Tang L DM carries a 1.5-litre turbocharged petrol engine, the BYD472ZQB, which works alongside the electric motors. Like any petrol engine it needs engine oil, an oil filter, an air filter and fuel system parts, along with its lambda and emission sensors. The same engine is used across the range, so service parts are usually common to every version. Output is quoted at 115 kW in China. Match each part by OE number before ordering.
What is different about the Drone Enthusiast Edition?
It carries a roof-mounted drone pod that raises the height from 1,760 mm to 1,970 mm, and it runs on 265/45 R21 tyres. It is an all-wheel-drive DM-p with 175 km of electric range on the Chinese test cycle, and at 2,670 kg it is the heaviest version. The pod parts belong to this car alone, and it is the only Chinese version listed with a tow hitch. Order roof and towing parts by OE number rather than by model name.
Can the Tang L DM tow?
It depends on the version. In China only the Drone Enthusiast Edition is listed with a tow hitch, and no hitch is listed for the other versions. Export cars are different, so do not assume that a hitch or its wiring from a Chinese car will fit an export car, or the other way round. Check whether the car already has a tow bar, then match the hitch and wiring by OE number.
Has the Tang L DM had a facelift?
Not yet, as far as published sources showed at the end of September 2026. The car launched in China on 9 April 2025, and its body, lights and bumpers have not changed since. In July 2026, reports from China showed an updated version with a new front light bar, reworked rear lights, flush door handles and new wheel designs. When that car goes on sale, those parts are likely to differ, so read the build date on the identification plate and match lamps, bumpers and handles by OE number.
