2003 Volkswagen Passat Question: My engine light has been on for 2+ years. I've paid out a lot to get it off, but

It still comes back on. What can be done. I am a senior citizen -

Yes. The test always says that there is a leake somewhere. The mechanic then proceeds to repair the car. Many things have been done including replacing the gascap. It is still on -
