Partially.

Authorized Changan workshops use OBD-II scanners, but many local mechanics rely on guesswork.

Faults like P0300 random misfire o r P0134 O2 sensor no signal may be misdiagnosed without full testing.

➡️ This leads to unnecessary sensor replacements, increasing costs without solving the root issue.
