Is there anything that typically triggers the CEL in '01 Golfs??

Ours has been on steadily for the past couple of weeks.

TIA

Okay, from what I've been hearing it's likely teh Catalitic Converter. I have no idea what that is, but supposidly over in Europe they have much cleaner fuel (97 octane is the norm I think) whereas here that is considered premium. So NA fuel is dirty and rough on the engines.l

 

Sorry for the long delay. Upon getting my car checked by a mechanic a few days ago........YES your right it does seem to be the cat as I asked him I was getting a hollow sound underneath the car and sure enough he said it's the catalytic converter.

After getting the engine lightdiagnosed as well as the cat I received the luck of this problem getting worse. I almost did not make it back to my home yesterday. The check engine light this time started blinking and upon 0-5 mph it started sputtering from the muffler.

I read on another forum that the Cat can get clogged? If this is the case does it sound like this is the culprit to my issue? I filled the engine up with more oil just to make sure, but I don't see how I needed too as I just got the oil changed a few days ago.

I started the engine up today and even on idle it sounded like it was sputtering from the back. If I hollow out the cat will this problem go away? If not does anyone know how much a used or new cat will cost me for my MK4 Golf GLS?
