Engine Light On / Aftermarket Radio
This has to be posted here somewhere but I can't seem to find it... blast me if you must but I'm out of time and I need some help.
The engine light on my 2002 Golf TDI (45k mi) came on tonight while I was driving home. I pulled over and checked the manual and it mentioned that it could mean a problem with the emissions system. The light was not blinking but it remained lit for the rest of the 40min drive.
After installing a Sirius satellite radio last year, a local stereo guy informed me that I may have trouble passing an emissions test. Apparently, if this is true, Volkswagen (for some bizarre reason) decided to route some of the emissions electronics through the car stereo. Does this sound right? Could it be causing my engine light to come on?
Also, what damage can be done if I drive with the light on for a bit? The vehicle drives fine and I don't know if I'll be able to make it into the shop for at least a few days.
Thanks for the help!
