If the check engine light comes on in your 2003 VW Golf, don't panic. It's crucial to take your car to a qualified mechanic as soon as possible to diagnose the problem and get it fixed. In the meantime, there are a few things you can do to try and pinpoint the cause of the problem:
* Check the gas cap. Make sure it's properly closed and not loose or damaged.
* Check the spark plugs and ignition coils. If they're worn out or damaged, they can cause the check engine light to come on.
* Check the air filter. If it's clogged or dirty, it can cause the engine to run lean and trigger the check engine light.
_If you're not comfortable performing these checks yourself, take your car to a qualified mechanic._
