We will never perform blind deep disassembly unless there are clear severe fault codes or extreme noises. The sealing of the engine and transmission is crucial, and compromising the factory seals to investigate non-existent issues is unprofessional. We rely on data flow and external acoustic and fluid analysis to make judgments.

Our technical report will read the environmental information from the vehicle's factory-issued documentation (including certifications like National V, National VI, etc.). You need to submit the specific emission limit data we provide (such as grams of CO, THC, NOx emissions) to your country's environmental or customs authorities for compliance comparison.

To prevent intermittent failures due to aging of the resistance wire, we will start the engine and set the seat heating/ventilation to maximum for at least 5 minutes, confirming significant temperature changes or airflow output in the cushion and backrest using an infrared thermometer or body sensor.
