When it cycles through tank pressure test, a leak will set MIL.
Uses about 1/2 psi to self check.
Have two customers with late MB's that will not fill up with the pump trigger pulled all the way up on automatic shut off.
One lady was 'drowned' to use her words at about half full when it shut of early and she was standing close.
Would like to know if this is common problem or a 'return to dealer' suggestion.
