Symptom Finder: Known Weak Points
| What you see or hear | Check first |
|---|---|
| Car will not wake or open although the main battery shows charge | Test the 12 V auxiliary battery first. The car cannot wake if it is low, whatever the charge in the Blade battery. Order a replacement by the OE number on the old unit. |
| Rust on the brake discs, or grinding after the car has stood | Discs and pads. Regenerative braking does much of the stopping, so the friction brakes can rust. Check the wheel size, then match discs and pads by OE number. |
| Knocking from the rear over broken surfaces | Look under the back first. Torsion beam cars wear their beam bushes, while cars with multi-link rear suspension have arms and bushes of their own. Order for the axle fitted. |
| Rear arm or bush bought for an Atto 3 will not fit | Most Atto 2s have a torsion beam rear, and the Atto 3 uses multi-link. Order rear suspension parts listed for the Atto 2, matched by OE number. |
| DC charging slower than expected | Compare the speed with the rate quoted for your version first, since it differs between versions. Only then suspect the charge port or charging hardware. |
| Puncture and no spare wheel in the boot | The car carries a tyre repair kit. Replace the sealant canister once it has been used, and read the tyre size on the sidewall before ordering a new tyre. |
| Parking sensor or driver-assistance warning after a minor knock | Check the sensors in the bumper and their brackets. A bent bracket can cause the warning on its own, so inspect it before replacing the sensor. |

About BYD Atto 2 Parts
The BYD Atto 2 is a compact electric SUV. It launched in China in March 2024 under BYD's Chinese-market name. It is 4,310 mm long on a 2,620 mm wheelbase. A single motor drives the front wheels, and an LFP Blade battery sits in the floor. Most cars use a torsion beam rear axle. One export version uses multi-link rear suspension instead, and a DM-i plug-in hybrid version adds a 1.5 litre petrol engine. Battery size, rear axle, wheel size and drivetrain all vary from car to car, so the right part depends on which version you have. Every part on this page is listed by its OE number, and matching the number on the old part is the surest way to confirm a part fits.
What to know before buying BYD Atto 2 parts
Start with the name, because this car carries several. In China it is sold under BYD's Chinese-market name. In some markets outside China it is sold under a name BYD had already used for an older, different compact SUV, and parts listed for that older car will not suit this one. Order by the OE number on the old part rather than by the badge.
The Atto 2 is also easy to mistake for a small Atto 3. Both sit on BYD's e-Platform 3.0, but the Atto 2 is the shorter car, with its own bumpers, lamps and panels. At the back, most Atto 2s use a torsion beam axle where the Atto 3 uses multi-link, so rear arms and bushes from an Atto 3 will not fit a torsion beam car.
Within the Atto 2 itself, four things vary from car to car. The first is the rear axle. Most cars use the torsion beam, but one export version has multi-link rear suspension, so look under the back of the car before ordering rear suspension parts. The second is the battery. Chinese cars use packs of 32, 45.12 or 51.13 kWh, and charging hardware follows the pack. Some export versions carry other pack sizes. The third is wheel size. Cars run 215/65 R16 or 215/60 R17 tyres, so read the sidewall before ordering tyres or rims, and match brake parts by OE number rather than assuming they carry across wheel sizes. The fourth is the drivetrain. The DM-i plug-in hybrid has a 1.5 litre petrol engine, a fuel system and an exhaust that the electric car does not, and its engine and motor mounts differ too.
For painted panels, order by the colour code on the car rather than by colour name, since the 2027 Chinese update added yellow and blue. Driver-assistance sensors sit in the bumpers on many cars, so a bumper repair can need sensors and brackets as well as the panel.
Finally, be careful with anything described as a rear-drive Atto 2. Reports in March 2026 described a planned rear-wheel-drive version, about 4,335 mm long with multi-link rear suspension. That car would differ underneath from the front-drive car covered here, so do not assume any structural, suspension or drive part carries across.
Before You Order: 7 Checks
- Order by the OE number on the part you are replacing rather than by the badge, since the car carries different names in different markets.
- Most cars have a torsion beam rear axle and one export version has multi-link, so look under the back of the car before ordering rear suspension parts.
- Read the tyre size on the sidewall, 215/65 R16 or 215/60 R17, before ordering tyres or rims, and match brake parts by OE number.
- Battery size varies by version, so confirm which pack is fitted before ordering battery, cooling or charging parts.
- Check whether the car is the DM-i plug-in hybrid before ordering engine, fuel, exhaust or mount parts.
- The September 2026 update in China added a new battery pack, so read the build date on the identification plate before ordering battery or charging parts for a Chinese-market car.
- Order painted panels by the colour code on the car rather than by colour name.
Generations and Facelifts
The Atto 2 has no direct predecessor. It sits below the Atto 3 and shares BYD's e-Platform 3.0 with it.
The car launched in China on 26 March 2024 as a front-wheel-drive electric SUV, 4,310 mm long, 1,830 mm wide and 1,675 mm high on a 2,620 mm wheelbase. In China a Smart Driving Edition added driver-assistance equipment on the same body. Outside China it is also sold as the Atto 2, and in some markets under the name of an older, unrelated BYD SUV. Some export versions differ underneath, including a DM-i plug-in hybrid and a version with multi-link rear suspension.
On 17 September 2026 BYD launched the 2027 model in China as the Feichi Edition. The body and dimensions did not change and every version uses a 70 kW motor. It added a 51.13 kWh battery alongside the 32 kWh and 45.12 kWh packs, two new colours and a two-spoke leather steering wheel. The body has not been facelifted. A rear-wheel-drive version was reported in March 2026 but had not gone on sale when this page was written. Before ordering battery, charging or rear suspension parts, read the build date on the identification plate and match by OE number.
BYD Atto 2 Parts: Frequently Asked Questions
How do I make sure a part fits my BYD Atto 2?
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 check matters on the Atto 2 because the same car carries more than one name, and because the rear axle, battery and drivetrain vary by version. 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 the Atto 2 sold under other names?
Yes. The car is sold in China under BYD's Chinese-market name, and outside China it is also sold as the Atto 2 and, in one market, the S1 Pro. Every version is 4,310 mm long on a 2,620 mm wheelbase. In some markets its badge repeats the name of an older, different BYD compact SUV, and that car's parts do not suit this one. If in doubt, compare the OE numbers on the old parts with the listings before ordering.
Do parts from the Atto 3 fit the Atto 2?
Body parts do not. The Atto 2 is a smaller car with its own bumpers, lamps and panels, even though both sit on BYD's e-Platform 3.0. The rear suspension usually differs too. Most Atto 2s use a torsion beam axle where the Atto 3 uses multi-link, so rear arms and bushes do not cross over. Some smaller mechanical parts may be shared between the two cars, but only a matching OE number proves it. Check the number on the old part before ordering anything listed for an Atto 3.
Which rear suspension does my Atto 2 have?
Most Atto 2s have a torsion beam rear axle, a single beam across the car with a bush at each end. One export version has independent multi-link rear suspension instead, and its arms, bushes and dampers are different. Both use MacPherson struts at the front. Look under the back of the car before ordering. A single cross beam means a torsion beam, and separate arms at each wheel mean multi-link. Then order by the OE number on the old part.
Which battery does the Atto 2 use?
Every version uses an LFP Blade battery, but its size varies by version. Chinese cars offer 32 kWh and 45.12 kWh, with 51.13 kWh added in September 2026. Some export versions carry other pack sizes. The DM-i hybrid has a much smaller 7.8 kWh or 18 kWh battery. Confirm which version you have before ordering battery, cooling or charging parts, and match each part by OE number.
How fast does the Atto 2 charge, and does that affect parts?
It depends on the version. The charging rate differs between versions, so there is no single figure for every car. The charging hardware follows the battery, so a charge port or on-board charging part from one version may not suit another. If charging seems slow, compare it with the rate quoted for your version first, then order any parts by OE number.
What is the Atto 2 DM-i?
The DM-i is the plug-in hybrid version. It adds a 1.5 litre petrol engine to the front-drive layout, with a 7.8 kWh or 18 kWh battery and system outputs of 122 kW or 156 kW. That brings engine, fuel, exhaust and filter parts the electric car never uses, and its mounts differ as well. Check which drivetrain is under the bonnet before ordering, and match body and trim parts by OE number.
Does the Atto 2 have a spare wheel?
No. The car comes with a tyre repair kit, so after a puncture you either use the sealant and compressor or replace the tyre. Replace the sealant canister once it has been used. Tyres are 215/65 R16 or 215/60 R17 depending on the version. Read the size on the sidewall of the tyres already fitted before ordering a tyre or rim, and replace tyres in axle pairs where wear is uneven.
What changed with the 2027 model in China?
BYD launched the 2027 model in China on 17 September 2026 as the Feichi Edition. The body and dimensions stayed the same, and every version uses a 70 kW motor. The main change is a new 51.13 kWh battery alongside the 32 kWh and 45.12 kWh packs. It also added two colours, yellow and blue, and a two-spoke leather steering wheel. For parts, take most care with battery and charging items. Read the build date on the identification plate and match those parts by OE number.
Is there a rear-wheel-drive Atto 2?
Not on sale when this page was written. Reports in March 2026 described a rear-wheel-drive version of the car, about 4,335 mm long, with its motor on the rear axle and multi-link rear suspension. If that car goes on sale, it will differ underneath from the front-drive car this page covers, so do not assume its suspension, drive or structural parts carry across. If the car in front of you drives its rear wheels, contact us through the quote form before ordering and we will reply within 24 hours, usually sooner.
Why will my Atto 2 not wake up when the main battery is charged?
Check the 12 V auxiliary battery first. Like most electric cars, the Atto 2 uses a small 12 V battery to power its locks, screens and control units, and the car will not wake if that battery runs low, whatever the charge in the Blade battery. Cars left parked for long spells are the most likely to show it. Test the 12 V battery before looking for faults elsewhere. If it needs replacing, order it by the OE number or the specification on the old unit.
Does the Atto 2 support vehicle-to-load, and what about towing parts?
The car supports vehicle-to-load, so it can run equipment from its battery. The rated output differs between versions, so check the figure for your car before relying on it. Towing hardware varies by market, so do not assume that a tow bar or wiring kit from one market fits a car from another. Check what is fitted to the car, then order any towing or vehicle-to-load part by the OE number on the existing one.
Safety Recalls Affecting This Model
If you have been told this car is under recall, the most likely explanation is a name mix-up. Confirm which car is meant before acting on it. The Yuan Up and Atto 2 are one car with two names, alongside the South American Yuan Pro and the Costa Rican S1 Pro. The Dynasty-era Yuan Pro is a separate, older BYD stocked separately, and the campaign against it belongs to that car, not this one. Check the badge and the market before treating any recall notice as relevant to parts ordered from this page.
