1990 W126 300SEL
1990 w126 300SEL check engine light problem!
Well my w126 has a check engine light on, but when i go to the flash box to try and pull the codes. Nothing happens. Not even one flash at least like its suppose to. I press the button and the led doesnt come on. I hold down the button for 10 seconds and still nothing happens, ive cycled the key after everything i tried. Please help. Very frusterating.
Also, i know there is a o2 sensor code stored and its been there for a while but i cant even see that one.
Would the led gone bad cause this?
