BYD Servicing Guide, What's Needed and What Do You Need to Know?

This is the core of the service, as here a trained technician will perform a multi-point inspection, focusing on the unique components of an EV.

Crucially, this means that you will get no oil change, no spark plugs, no fuel filters, and no exhaust check, which you may expect in petrol or diesel engine cars, as an EV simply doesn't have these.

Instead, here they will focus on:

High-Voltage System Inspection

This will tend to be a visual check of the bright orange high-voltage cables and connections for any signs of damage or wear, which is needed to keep the car safe.

Brake Inspection

They will check the condition of the brake pads, discs, and callipers for wear and corrosion.

Suspension and Steering Check

Inspect all the suspension and steering components for wear and tear, just like any other car.

Tyre Check and Rotation

Check the tyre pressures and tread depth, and the tyres are often rotated to ensure they wear evenly, extending their life.

Why does it matter?

This is all about making sure that the car continues to be safe and any preventative maintenance that is needed is noted before it becomes a problem, and decreasing your running costs down the line.

It also makes sure that the high-voltage electrical systems are all still in safe condition, that your brakes are in perfect working order, and it spots any issues like suspension wear before they become bigger problems as well.

This is a filter that cleans the air coming from the heating and air conditioning system into the cabin, and it is usually replaced at every service.

Why does it matter?

A fresh filter ensures you and your passengers are breathing clean air, free from dust, pollen, and pollution, and it also keeps your climate control system working efficiently as well.

A brake fluid service is based on time, not mileage. Here, just like a petrol car, your BYD will typically need a brake fluid change every two years.

What’s done?

The old brake fluid is completely drained from the system and replaced with new, manufacturer-approved fluid and the old brake fluid is then recycled appropriately as well.

Why does it matter?

Brake fluid absorbs water over time, which lowers its boiling point. In a heavy braking situation, this could cause the fluid to boil, leading to a soft pedal and reduced braking performance, so making sure this is maintained well is more than vital.

Your brakes are then checked at every service, but you’ll find they need replacing far less often than a petrol or diesel car tends to be due to the car's use of regenerative braking, as with an EV, the actual motor does a lot of the slowing down here over the brakes themselves.

What’s done?

The technician will measure the wear on your brake pads and discs and recommend replacement only when necessary.

Why does it matter?

This is where EVs have a big advantage over traditional fuel cars. Thanks to 'regenerative braking' (where the electric motor slows the car down and recharges the battery), the traditional physical brakes are used much less.

However, while they do last longer, they still need to be checked for corrosion or seizing from underuse to ensure they work perfectly when you need them. We should note.

A key part of modern EVs' maintenance is to make sure their complex electronic systems are performing at their best for you.

As a result, during a BYD service, a professional technician will connect your BYD to advanced diagnosis equipment to check this for you.

What’s done?

The technician performs a full system scan to check for any underlying issues, effectively troubleshooting any fault codes that may have been stored in the vehicle's memory.

This is also important when they will perform any required software updates, including potential remote updates that improve vehicle operation and performance.

Why does it matter?

These updates then make sure that your car benefits from the latest improvements in efficiency and functionality long after it leaves the factory, and the diagnostic checks also provide you with that secure feeling, knowing that the complex systems managing your battery and safety features are working exactly as they should - and any potential issues are resolved in a timely manner as well.

Battery Coolant

Your BYD's advanced Blade Battery has its own cooling system to keep it at the perfect temperature.

However, this coolant needs changing at a major service, perhaps every 4 years, to ensure that the battery longevity and optimal charging performance remain as you expect.

Drive Unit Fluid

The electric motor also has its own cooling/lubricating fluid that requires changing at set high-mileage intervals as well.

12V Battery Check

All EVs still have a small 12-volt battery to run the lights, wipers, and infotainment screen, and this can be tested during a service to make sure it's still healthy as well.
