I wonder if any one can help. I have a customer with a engine/spanner mil light on (orange EOBD light is not on).
I plugged in my AD pro and retrieved one code " ?1116 code unknown ". When cleared it came right back. I also checked the codes with multiscan and got P1116 unknown code. So I assume the ? on the AD Pro represents a P.
The Car drives well and appears to have no problems other than the manufacturers code spanner light on.
