Hi guys,

I really need your help on this one. As I posted earlier my car ('88 190E 2.6) failed emission test so I tried the seafoam treatment. I used the vacuum line from the thermovac to the throttle body. I'm not sure if this happened before or after, but now I'm reading an error on X11.

Is 1.03V read as 10% or 90% with a battery voltage of 13.8V? I think it's 90% but there's no equivalent error on the manual.

Thanks in advance.
