Please provide the fault code. It will need to be in standard format for OBD2 systems, not VW codes. The codes are in this format PXXXX, the X being numbers.

Do you have obd2 code scanner, use them to check the engine system. Maybe it got fault codes.

ALWAYS PERFORM TESTS AND REPAIRS ON THE FIRST DTC AND RETEST AFTER EACH STEP.ONE SENSOR OR COMPONENT FAILURE CAN CAUSE OTHERS TO FAIL AS A RESULT.MEANING THE FIRST CODE COULD HAVE CAUSED THE OTHER CODES TO CYCLE.SO ALWAYS DIAG THE FIRST CODE STORED AND EACH ONE AFTER AS THEY WERE READ DURING THE SCAN

02 sensor incorrect reading. once it is fixed you have to erase the code and drive up to 100 miles before trying for emissions again.

As you probably know by now there is no way to pass an emissions test as long as the check engine light is on....Your car is what they call an OBD2 system... You need to have the diagnostics codes pulled by a special tester specifically for OBD 2 systems... Once codes are pulled fix if necessary any problem and have the codes cleared... This will turn the check engine light off an enable you to pass smog providing your car is running properly...

Fallow the TOP A/C Line from the Firewall and you will see It in the Front Pass Side Fender Area

you need to pull the codes and go from there

I believe it does. It should be in the bottom part of the air cleaner box. There should be a vacuum hose connected to it from the throttle body boot.

THAT LEAK IS UN-METERED AIR ENTERING THE ENGINE, FIX IT AND RETEST SYSTEM. P103 IS A MAF CODE. A MAF MEASURES THE AIR ENTERING THE ENGINE, AND BASED THAT AND ON OTHER DATA THE PCM DECIDES THE AMOUNT OF FUEL TO INJECT.
