BYD Tang DM Parts

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. That matters on the Tang DM because the same body carried several powertrains, and the car itself changed for the 2019, 2020 and 2021 model years. If the old part is missing or its number cannot be read, send us a photo through the quote form and we will reply within 24 hours, usually sooner.

Look at the engine and gearbox. The Tang DM has a 1,999 cc turbocharged engine and a six-speed wet dual-clutch gearbox. The Tang DM-i, from 2021, and the Tang DM-p, from 2022, both use a 1.5-litre turbo engine with a different hybrid drive. All three share the second-generation body, 4,870 mm long on a 2,820 mm wheelbase, so the outline of the car will not settle it. Once you know which car you have, confirm each part by its OE number before ordering.

Only sometimes. The first-generation Tang, sold from 2015, also used a 2.0-litre turbo engine with front and rear motors, which is why the two get confused. It is a different car, though: 4,815 mm long on a 2,720 mm wheelbase against 4,870 mm and 2,820 mm, with 110 kW motors at both ends and a lithium iron phosphate battery. Body, chassis, battery and rear motor parts do not cross over. Some engine parts may, so check the OE number on the old part before ordering.

No. The single-motor version, added for the 2020 model year in September 2019, drops the 110 kW front drive motor and keeps the 180 kW motor on the rear axle. The engine drives the front wheels through the dual-clutch gearbox, so the car is still four-wheel drive. It also has a high-voltage BSG starter-generator on the engine. Front motor parts from a two-motor car do not apply to it, so count the motors before ordering and match each part by OE number.

Some do. Launch cars use the BYD487ZQA engine rated at 151 kW. From the 2019 model year the Tang DM was built to the China 6 emission standard and its engine is rated at 141 kW. Both are 1,999 cc, so the capacity will not tell them apart, and emission sensors and some ancillaries are not shared. Order these parts by the OE number on the old part, and read the build date on the identification plate if the number has worn away.

The 2021 model year went on sale on 16 August 2020. The body stayed the same, but the bright chrome trim became matt silver and the bumper vents turned darker. Underneath, BYD fitted an IPB integrated brake unit, FSD variable-damping dampers and a single controller for the BSG and front motor, and added driver-assistance features such as lane keeping and lane change assist. Brake control parts, dampers and trim differ either side of the change, so read the build date on the identification plate before ordering.

No. The 2.0-litre Tang DM uses a ternary lithium traction battery. At launch it came as the DM80 with about 20 kWh and the DM100 with 24 kWh and up to 100 km of electric range on the NEDC cycle, and later two-motor cars are listed at 22 kWh. BYD's Blade lithium iron phosphate battery went into the Tang EV for the 2021 model year, not into the Tang DM. Battery modules, packs and management parts do not cross between the two chemistries, so order battery parts by the OE number on the old unit.

Yes. The 1,999 cc turbo engine drives the front wheels directly through the gearbox, so it needs engine oil, an oil filter, an air filter, spark plugs and the sensors of any turbo petrol engine. The six-speed wet dual-clutch gearbox has its own oil, and the car carries a full fuel system with a 53-litre tank. Plan servicing around the engine and gearbox as well as the electric side, and order filters and seals by the OE number on the old part.

Not always. Cars from the 2021 model year, launched in August 2020, use an IPB integrated brake unit that combines the ABS valve body and the master cylinder in one assembly. Earlier cars have them as separate parts, and the two systems do not share control hardware. Every Tang DM has ventilated discs front and rear, but discs, pads and calipers should still be matched by OE number rather than assumed to carry over. Read the build date on the identification plate before ordering.

Launch cars run 255/50 R20 tyres on both axles and carry no spare wheel. Wheel and tyre sizes vary between trims and model years, so the size fitted to another Tang DM is no guide to yours. Read the size printed on the sidewall of the tyres already on the car before ordering tyres or rims, and order wheel bolts and centre caps by OE number at the same time so they suit the rim.

No. The Tang DM was launched with seven seats in a 2+3+2 layout, and five-seat versions were offered as well. Second and third-row seats, seat belts and floor and boot trim depend on the layout, so a cabin part from a seven-seat car may not suit a five-seat car. Check the seat layout in the car before ordering, then match each cabin part by the OE number on the old part.

Some body parts may, but drive parts do not. The Tang EV uses the same second-generation body, but it has no engine, no fuel system and no dual-clutch gearbox, and from the 2021 model year it used a Blade lithium iron phosphate battery. Motors, battery, cooling and engine-bay parts are specific to each car, and panels that look alike can differ in detail. Treat every part as separate until the OE number on your old part matches the listing.
