What is the function of the logo component on the car from BYD?
The logo of BYD vehicles does not have any mechanical or electronic "component functions". Its core role is to serve as brand identification and convey value:
Identity Identification: It distinguishes the BYD Group and its sub-brands (such as using seal script Chinese characters for the Dynasty series, oracle bone script "electric" for Yantou, rhombus chain for Fangche， and purple water droplet for Tengshi)， avoiding confusion with other car manufacturers；
Strategic Symbol： The new metal open-ended logo "BYD" launched in 2021， with the meaning of "breaking boundaries and open connectivity"， echoing the "Build Your Dreams" vision and reflecting a sense of technology and global positioning；
Cultural Carrier： The Dynasty series integrates small seal script， conveying the inheritance of Chinese culture； the overall design strengthens the brand perception of new energy， environmental protection， and innovation.
Note： If you actually want to refer to the "BYD Logo mini-component" in the mobile app (not the vehicle logo itself)， its function is：
Quickly view vehicle status (battery level/surcharge) on the phone home screen and perform remote vehicle control (lock car/window/open air conditioning)；
It needs to be added through the official "BYD Auto" or "BYD Ocean" app， relying on Bluetooth/4G to connect with the vehicle.
The logo is a static visual symbol and does not participate in vehicle operation control； any "control function" comes from the vehicle's onboard system (such as DiLink) or the mobile app component， rather than the logo itself.
First， confirm the specific type of "damage"， and then handle it accordingly：
If referring to the external vehicle logo (logo decoration) falling off/broken
Minor damage and not affecting the clarity of the inspection mark： It can be temporarily not replaced until the next inspection； if it has affected the appearance or there is a risk of falling， it is recommended to replace it as soon as possible.
Severe damage/missing：
Priority contact the BYD authorized service center (4S store)： Provide the vehicle frame number to query the original factory parts， and have professional personnel disassemble (avoid damaging the paint， accidentally touching the sensor)， and retain the replacement record to ensure the quality of the appearance part's warranty.
Self-replacement prerequisite：
Confirm the fixation method (screw/clip/glue)： Use a suitable tool to unscrew the screw； use a plastic pry bar to gently pry the clip； the glue needs to be softened by a hair dryer before carefully separating.
Clean the residual glue on the installation surface， align the position and fix firmly.
Note：Unauthorized replacement of non-original or modified vehicle logos may violate the "Motor Vehicle Registration Regulations"， affecting the inspection or insurance claims， and it is essential to use compliant original parts.
If referring to the electronic function logo component failure (such as illuminated marks， radar integration marks， charging port cover linkage marks， etc.)
This belongs to an electronic/body module problem， cannot be disassembled by oneself：
Try basic troubleshooting： Turn off the engine， disconnect the power supply， restart the vehicle， and check if the relevant fuses and plugs are loose.
Immediately schedule a visit to the BYD authorized service center， read the fault code through a dedicated diagnostic instrument (such as CAN communication abnormality， module power supply failure， etc.)， to avoid misjudgment and resulting in additional damage.
Within the warranty period (typically 5 years/100，000 kilometers， depending on the model)， non-human damage can be claimed and replaced for free.
Important Reminder
Quality Assurance Impact: The vehicle logo itself is generally not covered by the "lifetime quality guarantee for the powertrain". However, if improper operation causes damage to the surrounding wiring harnesses/sensors, it may lead to disputes.
Official Channels: Service reservations can be made through BYD's official website, APP, or by calling the 400 customer service hotline. Currently (as of August 2026), some stores offer fast(paint and body repair) services， and some exterior component replacements can be completed within 8 hours.
Do not easily believe the confusing statement that "chip damage = logo damage" - ordinary logos do not contain chips； only high-end illuminated logos or intelligent interactive logos contain simple circuits， and faults still require professional detection.
It is recommended to bring the vehicle registration certificate and purchase to the nearest authorized service center for on-site assessment. This is the most efficient and risk-averse approach.
