BYD in China

BYD is not a brand with a presence here, it is the market leader: CPCA retail data reported by CnEVPost put it first in 2025 passenger new-energy sales at 3.48 million units and 27.2% of the segment. That changes what independent service means for it. Parts and dealers are not the scarce thing. What is scarce is somewhere to take a BYD once it is outside warranty, bought used, or carrying a fault the dealer could not reproduce - and somewhere that will measure a pack before quoting to replace one.

What we expect to see

Four patterns, and most of the work is in them...

Four patterns account for most of the work on electric cars in a market like this one, and EVS workshops elsewhere see the same four. None of them is unusual. What is unusual here is how few workshops are equipped to tell them apart.

A battery quote that should have been a module

The first large out-of-warranty bills are arriving as the 2020-2023 cohorts leave cover. A pack is not always the answer: a single module, a contactor, a cooling circuit or a sensor can present the same way and cost a fraction. The difference is whether anyone measured before quoting.

Calibration nobody can complete

After a collision repair, a windscreen change or suspension work, the driver-assistance cameras and radar need recalibrating. Yicai Global has reported third-party repairers in Shanghai unable to obtain the data and equipment to do it. The car leaves looking finished, with its sensors pointing at the wrong place.

Thermal loss that never lit a warning

A cooling circuit running below par throws no fault code. It simply ages the pack, and the owner meets it two or three years later as range that will not come back. It is found by measuring coolant temperatures under load, not by reading codes.

A dead car with a full battery

No screens, no door unlock, no response - while the traction pack shows plenty of charge. It is the 12-volt battery, which wakes the car and which the high-voltage system cannot come on without. Cheap part, common failure, and it strands people who were told their car had 400 km left.

How a visit works

What this will look like when we open...

The Shanghai centre has not opened yet, so this is what we are building toward rather than what you can book today.

01

Tell us the symptom

Not the diagnosis. What the car is doing, when it started, and whether anything changed before it - a service, a collision, a software update, a cold week.

02

We measure before we quote

Fault codes say where the alarm went off, not why. Data streams, actuator tests and circuit measurements say why. The quote comes after that, not before.

03

You get the finding in writing

What is wrong, what it will cost, and what can wait. If a cheaper repair will do the job, that is the one we will put in front of you.

04

The work is verified, not just finished

Anything that needed coding gets coded. Anything that needed calibrating gets calibrated and recorded. A job that was not verified is a job that comes back.
