Recently took my 2000 passat for emissions test. Afterwards I got emmisions workshop on the display and check engine light. I thought it might be a loose gas cap. Retightened no change!
P0455 = EVAP Emission Control System Leak (Large). Could be as simple as a loose fuel cap. You can keep driving. This is only emissions related but it will fail an emissions test.

This happened to me too. The emissions test broke the diaphragm in the gas cap. Bought a new gas cap and it fixed everything.
it's talking about the emissions system. it is probably just a loose gas cap
EVAP (Evaporative Emissions) system failure could be caused by a loose gas cap. Inspect gas cap to make sure it is fastened properly. Go here for more info: http://www.2carpros.com/kpages/reading_diagnostic_codes.htm
The most common leaks are cracked vapor hoses and a loose gas cap.
The emissions light on a Honda Civic could indicate any number of problems including a loose gas cap. It could also indicate something more serious such as the engine is misfiring.

There is a problem with the emissions system. Check for a loose gas cap. If that is not the problem, seek out the services of a professional.
Using an incorrect fuel cap may illuminate the check engine light giving you a code for an EVAP leak and you will fail an emissions test.
That is an access port to pressure test the evaporative emissions system.
