Technical Bulletin
Tip:
The reading should be at 0 PSI or higher (no vacuum should be measured).
 If there is no vacuum present at the vacuum gauge, do not replace -N80- Activated charcoal filter system,
solenoid valve. The canister purge valve is not leaking and is not causing the fault codes to store. This bulletin
does not apply. Continue Guided Fault Finding based diagnosis.
 If vacuum is present, replace -N80- Activated charcoal filter system, solenoid valve. Perform leakage test to
verify there are no further issues.
 Clear any DTCs that were caused by disconnecting the canister purge valve electrical connector during the
test.
Note:
Performing a road test may not allow fuel tank leakage diagnostics to run. A tank leakage test must be performed
to verify repairs.

Canister Purge Valve on Jetta 1.4T (CNLA and CZTA engine codes):
 With engine off, disconnect EVAP line connection to -N80- purge valve beneath coolant expansion tank shown
