How do Pakistani workshops diagnose a failing purge valve in Changan Alsvin — is it often misdiagnosed as another issue?

In local workshops, is the purge valve often ignored o r wrongly replaced when symptoms point toward fuel delivery o r air intake problems?

Yes, in many local workshops, purge valve faults are misdiagnosed as:

Fuel injector issues

Idle air control IAC valve faults

Dirty throttle body

Weak fuel pump o r misfire

Few workshops have OBD-II scanners to read relevant codes o r test valve solenoids, so the root cause is often missed unless diagnosed at a Changan-authorized service center.
