    CE Error Code 51

    Hey Guys,

    I was installing my new guages and towards the end of the install when I tried to check the functionality of the new guages I got a check engine light. I got my peake tool out and did a code check. It gave me an error 51 "MSR signal, active too long". What the heck does that mean? Anyone have a clue?

    Thanks,
    Roman

    51 also sometimes means DWA input
    or 51 Ignition Angle Regulation (EML) on the 1.3 Motronic
    or 51 Shut-off Valve -Charcoal Filter or Request Control Unit Reset (MS43)
    or 51 Ignition Coil- Cyl 6
