Ditto the CPS. BUT, if you're unable to get a code to display with an illuminated CEL, it could be a bad computer (ECM). Rare but not impossible. It happened to a used car dealer friend who bought a C-Class. CEL lit, could pull no codes. It read there was a 'communication fault' on the reader. It was the computer. I hope that is not the case.
