Service engine soon light

I have a 2001 cadillac deville. I’ve had it in the shop 5 times and as soon as I drive away it comes back on. Is there any way to mask this code so I don’t have to look at the light. It is an emissions code.

What code is it?

Sorry, I don’t have that with me. Please check later.

It sounds like you need a new shop not some black tape over the light. Many parts stores like Autozone and Advanced Auto Parts will read those codes for free. Get the actual code (like PO123) and not just what the mechanic said it indicates and post it back here.
