My Mercedes Benz 1997 e320 yellow low fuel guage is flashing And check engine light came on? Any reasons why?
Well, you obviously need gas. That one is a given. (I would have thought).Check engine light could be on for numerous reasons. You need a mechanic for that. Could be something simple, like you need to check/fill your fluids.
Probably need new fuel sensor. Go get a diagnostic check at reputable mechanic.
