Symptom Finder: Known Weak Points
| What you see or hear | Check first |
|---|---|
| Jerky pull-away, slipping or a missing gear on a turbo car | The six-speed dual-clutch gearbox. Check the fluid first, then the clutch and control unit, and order by the OE number on the old part. |
| Clutch slipping or a heavy pedal on a 1.5 manual | The clutch kit and release bearing. These suit the manual car only, so match them by OE number. |
| Engine warning light | Start with the lambda and emission sensors, the usual first suspects on any petrol engine, and order them against the engine code. |
| Low boost, whistling or oil smoke on the 1.5 turbo | The turbocharger, its oil feed and the intake hoses. None of these are fitted to the naturally aspirated 1.5. |
| Dual-mode car will not run on electric power or will not charge | The charging socket, the traction battery and the high-voltage system. These parts exist only on the dual-mode car, so confirm it is one before ordering. |
| New front bumper or grille does not line up with the lamps | The part is probably from the other side of the 2018 facelift. Read the build date on the identification plate and match the part by OE number. |
| Brake squeal, judder or a soft pedal | Pads and discs. Check what is fitted to the rear axle and order pads to suit the disc and caliper on the car. |

About BYD Yuan Parts
The car on this page is BYD's original petrol and plug-in hybrid subcompact SUV. It was first shown as the BYD S1 and was officially launched in China on 11 April 2016. It came in three forms: a 1.5-litre petrol engine, a 1.5-litre turbo, and a dual-mode plug-in hybrid that adds an electric motor to each axle for four-wheel drive. The petrol cars drive the front wheels. Every version therefore needs combustion parts such as oil, filters, emission sensors, clutches and gearbox hardware. Only the dual-mode car needs drive motors, a traction battery and high-voltage hardware. The battery-electric models that shared its body or later took its name are different cars with their own pages. Every part here is listed by its OE number, and matching the number on the old part is the surest way to confirm a fit.
What to know before buying BYD Yuan parts
Start by confirming which version you are working on. BYD has used this model name on several cars. This page covers the original 2016 subcompact with a petrol engine, sold as a front-wheel-drive petrol car or as the dual-mode plug-in hybrid. The battery-electric EV360 and EV535 used the same body from 2018, and the later Pro, Plus and Up models are separate cars. A fuel filler flap and an exhaust rule out the electric versions straight away. Some body and trim parts may cross between petrol and electric cars on the shared body, but nothing in the engine, gearbox, exhaust or fuel system does, so confirm every body part by its OE number.
Next, identify the powertrain. The naturally aspirated 1.5, engine code BYD473QE, makes 80 kW and was offered with a five-speed manual. The 1.5 turbo, engine code BYD476ZQA, makes 113 kW and drives through a six-speed dual-clutch gearbox. The dual-mode car pairs its engine with electric motors on both axles and is the only version here with four-wheel drive, a rear drive unit and a traction battery. Clutches, gearboxes and driveshafts do not interchange between these three versions, so read the engine code on the block and check which gearbox is fitted before ordering.
Order engine ancillaries by engine code and OE number rather than by model name. BYD used the same engine families in other models of the period, so an intake, ignition or cooling part for one of these engines may also be listed under another BYD car. When the OE numbers match, the part is the same. Motor and battery parts for the dual-mode car never cross to the petrol versions.
The 2018 facelift gave the car BYD's Dragon Face front end. Treat the front bumper, grille, lamps and front trim from before and after that change as different parts. Read the build date on the identification plate before ordering anything for the front of the car, and order painted parts by the colour code on the car rather than by the colour name.
Brakes and wheels vary by trim. The 1.5 turbo flagship has discs front and rear, but do not assume every car matches it. Look at the rear axle of the car you are working on before ordering rear brake parts, and read the tyre size on the sidewall before ordering wheels, tyres or discs.
Before You Order: 7 Checks
- Look for a fuel filler flap and an exhaust to confirm the car is a petrol or dual-mode version, then order from this page rather than a battery-electric listing.
- Match the OE number on the part you are replacing to the OE number on the listing before you order.
- Read the engine code on the block, BYD473QE for the 1.5 or BYD476ZQA for the turbo, and order engine ancillaries against it.
- Check whether the car has a manual, a dual-clutch gearbox or the dual-mode drive, and order clutch, gearbox and driveshaft parts to suit.
- Read the build date on the identification plate before ordering a front bumper, grille or lamp, since the 2018 facelift changed the front end.
- Look at the rear axle and read the tyre size on the sidewall before ordering brake, wheel or tyre parts.
- Order painted panels by the colour code on the car rather than by the colour name.
Generations and Facelifts
The car began as the BYD S1, the name the petrol subcompact carried when it was first shown in 2015, and it took its current name before going on sale. Cars reached BYD dealers in February 2016, and the model was officially launched on 11 April 2016 in three forms. The 1.5 had 109 hp, the 1.5 turbo had 154 hp, and the dual-mode plug-in hybrid had electric drive on both axles, a claimed electric range of 85 km and 0 to 100 km/h in 4.9 seconds. The dual-mode car is the only version on this page with high-voltage parts.
In 2018 the car was facelifted with the Dragon Face front end used across BYD's Dynasty range. On the petrol cars this is the main date split for parts. Match the front bumper, grille and lamps by OE number, and use the build date on the identification plate to tell which side of the change a car falls on. The battery-electric EV360 arrived on the same body in 2018, followed by the larger-battery EV535. Those electric versions share the shell but none of the powertrain.
In 2021 a further refresh became the battery-electric Pro model, with a new front end in the style of the Han EV, and the original petrol car ended production that year. The Plus followed in 2022 and the Up in 2024. Both are separate cars with their own parts. For a petrol or dual-mode car, the powertrain and the 2018 facelift decide most fitment questions. The model year on its own does not.
BYD Yuan Parts: Frequently Asked Questions
How do I make sure a part fits my car?
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. The check matters on this model because its name covers petrol, dual-mode and battery-electric cars, and several of them share a body while differing underneath. If the old part is missing or its number is unreadable, send a photo through the quote form and we will reply within 24 hours, usually sooner.
Is this the same car as the battery-electric EV360, Pro or Plus?
No. This page covers the original model with a petrol engine, sold from 2016 as a petrol car or as a dual-mode plug-in hybrid. The battery-electric EV360 and EV535 were built on the same body from 2018, the Pro followed in 2021, and the Plus and Up are separate, newer cars. None of them has an engine, gearbox, exhaust or fuel system. Body and trim parts may cross between cars on the shared body, but only where the OE numbers match, so check the number before ordering.
What engines does the original model use?
Two petrol engines, both 1.5 litres. The naturally aspirated BYD473QE makes 80 kW, or 109 hp, and 145 Nm. The turbocharged BYD476ZQA makes 113 kW, or 154 hp, and 240 Nm. The turbo carries parts the 1.5 does not have, including the turbocharger, its oil feed and the boost pipework, so many intake and cooling parts differ between the two engines. Read the engine code on the block before ordering ancillaries, and then match each part by OE number.
What is the dual-mode version?
It is the plug-in hybrid version, launched with the rest of the range in April 2016. It pairs a petrol engine with electric motors on the front and rear axles, which gives it four-wheel drive, a claimed electric range of 85 km and 0 to 100 km/h in 4.9 seconds. It is the only version on this page with a traction battery, drive motors, a rear drive unit and a charging socket, and none of those parts fit the petrol cars. Confirm the car is a dual-mode before ordering any high-voltage or rear drive part.
Does the car have a manual or an automatic gearbox?
It depends on the engine. The 1.5 was offered with a five-speed manual, and the 1.5 turbo with a six-speed dual-clutch gearbox. Some listings also show an automatic for the 1.5, so check the car itself rather than relying on the trim name. Clutch, gearbox and driveshaft parts do not interchange between a manual car, a dual-clutch car and the dual-mode car. Look at the pedals and gear lever to confirm what is fitted, then match the part by OE number.
Do its engine parts fit other BYD models?
Some may. BYD used its 1.5-litre engine families in other cars of the same period, so an intake, ignition or cooling part for one of these engines can also appear under another BYD model. For that reason, order engine ancillaries by engine code and OE number rather than by model name. A matching number means the part is the same. Treat body, interior and dual-mode battery parts as specific to this model unless the OE number shows otherwise, and check the number on the old part before you order.
What changed with the 2018 facelift?
The 2018 facelift gave the car BYD's Dragon Face front end, in line with the rest of the Dynasty range. For parts, that makes the front of the car the main date split. Do not assume the bumper, grille, lamps or front trim from before and after the change will interchange. The battery-electric EV360 arrived on this body in the same year. Read the build date on the identification plate before ordering front-end parts, and then match each one by OE number.
Why is the car sometimes listed as the BYD S1?
The car was first shown as the BYD S1 in 2015 and was renamed before it went on sale in 2016. That is why some catalogues and older parts listings still use the S1 name or a 2015 date. The name on a listing matters less than the number on the part. If the OE number on your old part matches the listing, the part fits whichever name the listing uses. If you are unsure, send the details through the quote form and we will reply within 24 hours, usually sooner.
Which brakes and wheels does the car use?
Brakes and wheels vary by version. The 1.5 turbo flagship has disc brakes front and rear, but the range covers several trims, so do not assume every car matches it. Look at the rear axle before ordering rear brake parts, and read the tyre size on the sidewall before ordering wheels, tyres or discs, since wheel size can change the disc and caliper needed. Order pads to suit the disc and caliper actually fitted to the car, and match each part by OE number.
Does the dual-mode version still need engine servicing?
Yes. Alongside its battery and motors, the dual-mode car carries a petrol engine, so it needs engine oil, oil and air filters, spark plugs and the lambda and emission sensors that any petrol car has. Because it can run on electric power alone for short trips, the engine may run less than it would in a petrol version, but it still needs regular servicing. Plan for both sets of parts, and order the engine items to suit the engine fitted, matched by OE number.
What should I order when the dual-clutch gearbox plays up?
Find the fault before you order. Jerky pull-away at low speed, slipping or a missing gear on a dual-clutch car can come from the fluid, the clutch or the control unit, and each is a different part. Start with a diagnostic read and a fluid check, then order the clutch or control parts the fault points to. These parts belong to the dual-clutch cars and do not fit the 1.5 manual. Match every gearbox part by the OE number on the old unit.
How do I order a painted panel?
Order by colour code and OE number. The car was sold in a range of colours, including two-tone schemes, so a colour name alone can be misleading. Read the paint code on the car and quote it with the OE number of the panel. If the panel is at the front, check the build date on the identification plate as well, since the 2018 facelift changed the bumper, grille and front trim. Then order the panel that matches both the code and the number.
Safety Recalls Affecting This Model
Because recall status is checked against the individual VIN, confirm the exact car against BYD's current campaign lookup before carrying out any powertrain or steering work, rather than relying on what has applied to similar models.
