I have a 2001 VW Cabrio that failed inspection because the check engine light will not come on. Even when turning the key to the on position, all instrument panel lights illuminate, but the check engine light does not. I did not have any other codes when going through inspection. Any ideas?

Hi jfuzz521, Welcome to 2carpros and TY for the donation

Could be burned-up bulb or its been removed to hide problems within the engine mangement system

If you've plugged into your car's diagnostic port and aren't reading anything at all, you might think that your OBD-II brain has fried, but don't declare it dead yet.
On many cars, the ECM (that's the electronic brain) is on the same fuse circuit as other electrics like the cigarette lighter/accessory port. The lighter is prone to blow fuses on some vehicles, and if there's no juice going to the ECM, it can't tell you what's wrong.

If you're getting nothing, check the fuse no.16 and 21 if okay test the wiring from these fuses to the computer
