Thread starter oceanromeo Start date 22 Dec Currently out of UK and have had this amber warning light illuminate.
Vehicle behaviour is otherwise quite normal. Was advised by VW Breakdown Assist. There are a variety of reasons for a check engine light to come on, which is why it tends to pop up more frequently than other lights, which tend to be very specific. The first thing to note is the color of the check engine light is yellow, a color used to indicate a warning rather than an emergency. These are the most common reasons why a VW check engine light comes on, but there are many more.
Read More: Why you change your oil. Gas Cap : We kid you not, a loose or damaged gas cap can trigger one of the scariest lights in your gauge cluster. Maybe there's some confusion of the light. Does it look like this? No, it is an outline of an engine. Explained on page of the manual as a catalytic converter warning light. It is not a DPF light. I'm not aware of a catalytic converter warning light, but thats how it may be written in the manual poor translation?
The light that is yellow, with an outline of an engine is the check engine light CEL. In this case, I would agree with the dealer's suggestion of checking the fuel cap, however I don't know if the TDI has an evaporative emissions system that would cause the light.
In a gasser, not tightening the fuel cap properly will trigger the CEL, as they have a sealed fuel system to prevent gasoline from evaporating into the atmosphere. Most likely there is another culprit causing the CEL.
PaulGiz Veteran Member. My heart couldn't take it. The car gets lots of highway miles. Went to Philly last week, Massachusetts two weeks ago. Called the dealer this morning about the catalytic converter light.
He asked if it was blinking. Drive for two days. If the light does not go out, bring it in for service. Or, if it starts running rough, bring it in. Sounds reasonable to me.
The manual covers both gassers and Diesels. There is no charcoal filter and no associated plumbing, especially the vacuum lines, which are what trip a CEL if they suck outside air around the seal of a loose cap.
It may not me a catalytic converter issues, but more along the lines of EGR valve, Flapper vlave, rail pressure out of spec, low boost, or anything other of the million other things that cause the CEL mostly it's the emissions equipment. If you have a local auto place that can read the P-code, you can look it up yourself just don't clear it so you know what to tell the dealer. So they know where to look.
Fixmy59bug Veteran Member. Gray, The manual is very non-specific when it comes to the causes for the lights. If that light is on, it could be one of a hundred reasons which could potentially cause damage to the catalytic convertor.
One of those reasons could be a defective catalytic convertor remember, you have two, plus a particulate filter , or a defective sensor somewhere. But as it was said earlier, as long as it is not flashing then it is safe to drive to the dealer.
If it starts flashing, Call Roadside Assistance.
