BYD Song L EV 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 check matters on the Song L EV because it shares its name with the Song L DM-i, a different car, and because parts vary between rear-drive and four-wheel-drive cars and between sensor builds. 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.

No. The Song L DM-i is a plug-in hybrid with a 1.5 litre petrol engine, on sale since 25 July 2024. It is 4,780 mm long, 1,898 mm wide and 1,670 mm tall on a 2,782 mm wheelbase. The Song L EV is 4,840 mm long, 1,950 mm wide and 1,560 mm tall on a 2,930 mm wheelbase. Body panels, glass, suspension and brake parts do not cross between the two. If you are unsure which car you have, look for a fuel filler flap, since only the hybrid has one. Then order by OE number.

Every version of the Song L EV runs a staggered set, narrower at the front than at the rear. Cars on 19-inch wheels use 235/50 R19 at the front and 255/50 R19 at the rear. Cars on 20-inch wheels use 245/45 R20 at the front and 265/45 R20 at the rear. The tyres cannot be swapped between axles, so they wear as two separate pairs. Read the size on the sidewall of each axle before ordering, and buy tyres in axle pairs.

Every Song L EV has a rear motor, rated at 150 kW on the 550 km versions and 230 kW on the 662 km versions. The 602 km four-wheel-drive car adds a 150 kW motor at the front for 380 kW in total, and at up to 2,385 kg it is the heaviest version. The front drive unit, its mounts and the front driveshafts are found only on that car. Rear motors also differ by output, so check which version the car is, then match drive parts by OE number.

Treat them as different parts. Both are BYD Blade lithium iron phosphate packs, built into the car's structure with BYD's cell-to-body design. The 71.8 kWh pack goes with the 550 km versions, and the 87.04 kWh pack with the 602 km and 662 km versions. Because the pack forms part of the floor, it is matched to the version it came from. Confirm which version the car is before ordering, then order battery and battery-management parts by the OE number on the part fitted.

No. The Song L EV uses DiSus-C, BYD's electronically controlled damping, so each damper is an adaptive unit with an electrical connection that changes its rate as the road changes. A passive damper of the same length will not work with the system. The front suspension is a double wishbone design and the rear a five-link design, and arms, bushings and knuckles should be ordered for the correct axle and side. Match each damper by the OE number on the old unit.

Only some cars do. The Smart Driving Edition, launched on 10 February 2025, came in four versions. The 662 km lidar version and the 602 km four-wheel-drive version carry a lidar and the God's Eye B system. The 550 km version and the other 662 km version use cameras and radar only, under God's Eye C. Cars built before February 2025 have no lidar. Check the car and read the build date on the identification plate before ordering glass or sensor parts, then match by OE number.

The 2025 model was launched on 30 August 2024. The body, dimensions and range figures stayed the same. The main change was the DiPilot 100 driver-assistance system, made standard on every version, with 29 sensors: 12 cameras, five millimetre-wave radars and 12 ultrasonic sensors. The line-up also dropped from five versions to four. For parts, the sensors, their brackets, the windscreen and the bumpers are what to check. Read the build date on the identification plate before ordering any of them.

Check which sensor build the car has. Cars from the 2025 model onwards carry DiPilot 100 cameras, and cars from February 2025 may also have a lidar. The windscreen, its camera bracket and the trim around it must suit the build fitted, and a front camera will normally need calibrating after the glass is changed. Read the build date on the identification plate, check whether a lidar is fitted, and order the glass by the OE number on the old screen.

It can. On e-Platform 3.0 cars, the heat pump and refrigerant circuit control the battery's temperature as well as the cabin's, so the compressor, valves and sensors in that circuit serve both. A compressor fault can show up as slow charging or a battery temperature warning as well as poor heating or cooling. Diagnose the circuit before ordering. The system holds refrigerant under pressure, so the work belongs with a workshop that has the right equipment. Then order each part by OE number.

On the four-wheel-drive car, yes. Ventilated discs are listed at the front and the rear, on a car weighing up to 2,385 kg, the heaviest in the range. Brake specifications can differ between versions, so check the disc on the car before ordering, including its diameter and whether it is vented. Order the pads to suit the caliper, and the caliper by axle and side. Match each part by the OE number on the old one.

No spare wheel is fitted, so a puncture that cannot be repaired means a new tyre. Because the tyres are staggered, the replacement has to match the axle it goes on: 235/50 R19 or 245/45 R20 at the front, 255/50 R19 or 265/45 R20 at the rear. Check the tread on the other tyre on the same axle too, since a badly mismatched pair can upset the handling. Read the sidewall, then order the right size for that axle.
