check engine electronics 96 320e
 

Hello,
My '96 E320 sometimes the check engine electronics light goes on when I start the car and sometimes not. I took the cars for smog check and they said no code found but 4 other thing is not clear. They told me to drive the car for a few days and check it again but the problem does not go away.
What's wrong??? Please help.:confused:
Thanks

You need to have the codes READ & post them..ie; P0 130
