Symptom Finder: Known Weak Points
| What you see or hear | Check first |
|---|---|
| Powered sliding door slow, jerky or stopped | The drive cable, pulleys and rollers in the door rail. On powered sliding doors the cable often wears before the motor does, so inspect it before ordering a motor, and order by side. |
| Hand-pulled sliding door heavy or dropping on a pre-2013 car | The door rollers, rails and latch. Clean and inspect the rails first, then order worn rollers by the OE number on the old part. |
| Steering heavy, or assistance coming and going | The power steering pump, its drive belt, the fluid level and the hoses. The M6 has hydraulic assistance with no electric steering motor, so start with the belt and fluid. |
| Judder or shunt when pulling away in a dual-clutch car | The clutch pack and gearbox control parts. Only cars from the 2015 model year, on sale from October 2014, have the dual-clutch, so confirm the gearbox first. |
| Handbrake lever travels too far or does not hold | The rear brake cables, their adjustment and the rear pads. Every M6 uses a hand lever, so there is no electric parking brake to diagnose. |
| Oil seeping from the top or bottom of the engine | The camshaft cover and sump gaskets and the seals around them. Identify the engine code first, since the three engines take their own gaskets. |
| One view missing from the 360-degree camera display | The camera for that view and its connector. Surround cameras arrived with the February 2013 facelift, so order by the OE number on the old camera. |
| An engine part ordered for a 2.4 does not fit | The engine code on the block. The 4G69 and the 488QA are different engines, so order against the code rather than the badge. |

About BYD M6 Parts
The BYD M6 is a seven-seat petrol MPV. It was the first MPV BYD built in volume, made from 2010 to 2017 and sold in China from July 2010. It has a transverse four-cylinder engine driving the front wheels. The engine is BYD's 2.0-litre 483QB, Mitsubishi's 2.4-litre 4G69 or, from the February 2013 facelift, BYD's own 2.4-litre 488QA. Gearboxes range from five and six-speed manuals to a four-speed automatic and, on late cars, a six-speed dual-clutch. For parts, that makes it a conventional combustion car: oil and filters, valvetrain, cooling, clutch and gearbox parts, and hydraulic power steering, plus the rails, rollers and drive hardware of its sliding side doors. The engine and the build date split most parts. Every part here is listed by its OE number, and that number on the old part is the surest check that a replacement fits.
What to know before buying BYD M6 parts
Start by making sure the car is the right M6. Since 2024 BYD has sold a battery-electric MPV under the M6 name in export markets. It is a different design from the car on this page, so do not cross-reference parts between the two. The petrol M6 of 2010 to 2017 measures 4,820 mm long, 1,810 mm wide and 1,765 mm tall on a 2,960 mm wheelbase, with a petrol engine under the bonnet. The body kept the same size throughout the run, so measuring it will not date a car.
The main date split is the facelift that went on sale on 17 February 2013. It brought a new grille with more chrome, a new front bumper and clear headlamps in place of the earlier smoked ones, so grilles, bumpers and headlamps from either side of that date do not match. It also added powered sliding side doors, opened from the smart key and fitted with anti-pinch protection, and a 360-degree camera system. Earlier cars have hand-pulled sliding doors and no surround cameras. Before ordering door drive parts, latches, camera parts or front-end panels, read the build date on the identification plate and check whether the doors open by hand or by motor.
The engine is the next check, because two different engines wear a 2.4 badge. Mitsubishi's 4G69 came with a four-speed automatic from launch. BYD's own 488QA arrived with the facelift, first with a six-speed manual. From the 2015 model year, on sale from October 2014, it was also offered with a six-speed dual-clutch gearbox. The 2.0-litre 483QB had a five-speed manual. No M6 had a turbocharged engine. Read the engine code on the block before ordering engine, clutch or gearbox parts, and treat a dual-clutch car as a late build.
Much of the chassis stays the same across the run. The front has MacPherson struts and the rear a torsion beam. The brakes are ventilated discs at the front and discs at the rear, with a hand-lever parking brake that works through cables. Steering is hydraulically assisted by a belt-driven pump. Many cars run 215/55 R17 tyres with a full-size spare, but tyre size varies by year and trim, so read the sidewall. For painted panels, order by the colour code on the car rather than by colour name.
Before You Order: 8 Checks
- Confirm the car is the 2010 to 2017 petrol M6 and not the electric MPV sold under the M6 name since 2024 before ordering anything.
- Match the OE number on the part you are replacing to the OE number on the listing before ordering.
- Read the build date on the identification plate before ordering a grille, front bumper, headlamp, door drive part or camera part, since the 17 February 2013 facelift changed all of them.
- Check whether the sliding doors open by hand or by motor, and order door hardware to suit.
- Read the engine code on the block before ordering engine parts, since the 4G69 and the 488QA both wear a 2.4 badge.
- Check whether the car has a manual, the four-speed automatic or the six-speed dual-clutch, then order clutch, gearbox and mount parts to match.
- Read the tyre size on the sidewall before ordering tyres or rims.
- Order painted panels by the colour code on the car rather than by colour name.
Generations and Facelifts
The M6 had no MPV predecessor at BYD. It was first shown in 2009 and formally introduced at the Beijing Auto Show in 2010. It went on sale on 20 July 2010 as BYD's first volume-built seven-seat MPV. Early cars used the 2.0-litre 483QB with a five-speed manual or Mitsubishi's 2.4-litre 4G69 with a four-speed automatic. They had hand-pulled sliding side doors and smoked headlamps.
The facelift went on sale on 17 February 2013. It changed the front of the car with a new grille, a new front bumper and clear headlamps, and added chrome trim above the rear number plate. It also brought powered sliding doors, a 360-degree camera system and BYD's own 2.4-litre 488QA engine with a six-speed manual. This is where front-end panels, lamps, door drive hardware and camera parts split, so check the build date on the identification plate before ordering any of them.
The 2015 model went on sale in October 2014 and paired the 488QA with a six-speed dual-clutch gearbox. The body and chassis were carried over, so the change matters mainly for clutch, gearbox and mounting parts. The shell kept the same dimensions throughout, and the M6 had no second generation.
Production ended in 2017. The Song Max, launched in September 2017, took over as BYD's MPV. It is a smaller car on a 2,785 mm wheelbase with a 1.5-litre turbo engine, so do not assume its parts fit an M6. The M6 name returned in 2024 on an electric MPV sold in export markets, which is a separate car again.
BYD M6 Parts: Frequently Asked Questions
How do I make sure a part fits my BYD M6?
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 M6 because the engine fitted and the February 2013 facelift both split parts that look alike. If the old part is missing or its number cannot be read, send details through the quote form with a photo and we will reply within 24 hours, usually sooner.
I have seen an electric BYD M6. Is it the same car?
No. Since 2024 BYD has sold a battery-electric MPV called the M6 in export markets. It is a different design with an electric drive, and it should not be cross-referenced with the petrol MPV on this page. The petrol M6 was built from 2010 to 2017 on a 2,960 mm wheelbase, with a petrol engine under the bonnet and sliding side doors. Confirm which car you have first, then match each part by the OE number on the old part.
Which engine does my M6 have?
One of three, all petrol and all naturally aspirated. The 2.0-litre is BYD's 483QB. The 2.4-litre is either Mitsubishi's 4G69, fitted from launch in 2010, or BYD's own 488QA, added with the February 2013 facelift and rated at 123 kW and 234 Nm. Both 2.4 engines wear the same badge, so the badge will not tell you which is fitted. Read the engine code stamped on the block and order engine parts against that code and the OE number on the old part.
Which gearbox does my M6 have?
It depends on the engine and the date. The 2.0-litre had a five-speed manual. The Mitsubishi 2.4 had a four-speed automatic. BYD's own 2.4 arrived in February 2013 with a six-speed manual, and from the 2015 model year, on sale from October 2014, it was also offered with a six-speed dual-clutch gearbox. A dual-clutch M6 is therefore a late car. Confirm the gearbox before ordering clutch, gearbox, mount or fluid parts, then match each by OE number.
Does my M6 have powered sliding doors?
It depends on when it was built. Powered sliding doors arrived with the facelift that went on sale on 17 February 2013. They open from buttons on the smart key and have anti-pinch protection. Earlier cars have hand-pulled sliding doors. The drive motor, controller, cable and related latch parts belong to the powered doors only, so they are no use on an early car. Read the build date on the identification plate, check how the doors actually open, then order door hardware by OE number.
The powered sliding door has stopped. Is it the motor?
Not necessarily. On powered sliding doors the drive cable, its pulleys and the rollers in the rail wear with every opening, and a frayed or slack cable can stop the door while the motor still runs. Listen for the motor when the door is operated. If it runs but the door does not move, inspect the cable and rail parts first. If it is silent, check the fuse, wiring and latch before ordering a motor, and order by side and OE number.
What changed at the 2013 facelift, and does it matter for body parts?
Yes, mainly at the front. The facelift that went on sale on 17 February 2013 brought a new grille with more chrome and a sharper V shape, a new front bumper and clear headlamps in place of the earlier smoked units. It also added chrome trim above the rear number plate. Grilles, front bumpers, headlamps and that rear trim should be matched to the build date. The side profile and body dimensions did not change. Read the build date on the identification plate, then order by OE number.
Was there a turbocharged M6?
No. Every M6 left the factory with a naturally aspirated petrol engine: the 2.0-litre 483QB, Mitsubishi's 2.4-litre 4G69 or BYD's own 2.4-litre 488QA. If a turbocharger, intercooler or turbo pipe is described as fitting an M6, the listing is for a different car, most likely another BYD from the same period. Read the engine code on the block and check the OE number on the old part before ordering anything described as a turbo part.
The steering has gone heavy. Is it an electric fault?
Unlikely. The M6 uses hydraulic power steering, with a pump driven by the engine's auxiliary belt, and has no electric steering motor. Heavy or intermittent assistance usually traces back to the belt, the fluid level and condition, the pump or a leaking hose. Check belt tension and look for fluid on the hoses and around the rack first. Use the power steering fluid specified for this car, and order the pump, belt or hoses by the OE number on the old part.
What tyres and spare wheel does the M6 use?
Many M6s run 215/55 R17 tyres front and rear, including 2013 and 2015 cars, but the size varies by model year and trim. Read the sidewall of the tyres already fitted before ordering. The M6 carries a full-size spare, so if you are replacing wheels, include the spare when matching rims and tyres. Check the wheel size against the OE number on the rim, and order the set to match what is on the car.
Does the M6 have an electric parking brake?
No. Every M6 uses a hand lever that works the rear brakes through cables. The front brakes use ventilated discs and the rear brakes use discs as well. If the lever travels too far or will not hold the car, check the cable adjustment and the rear pads and discs, and look for seized or stretched cables. There is no electric actuator to replace, so order rear calipers, pads and cables by the OE number on the old part.
Will parts from the BYD S6 or Song Max fit the M6?
Do not assume so. The S6 is an SUV with a different body, so its panels, doors, glass and trim will not fit the M6, though some engine parts may be shared where the engine is the same. The Song Max that replaced the M6 in 2017 is a smaller car with a different engine. For any part, the reliable check is the OE number on the old part. If you are unsure, send it through the quote form and we will reply within 24 hours, usually sooner.
