Title: Boost leak or failed component? Post by: dokalanyi on January 06, 2017, 02:05:52 PM Hi All,
I'm getting WGDC of 100%. Car was running fine on same tune. It has cut off power at one point, but I failed to replicate even after hard driving. I've attached logs.

if it were a boost leak, i'd expect the opposite lambda control action. Title: Re: Boost leak or failed component? Post by: nyet on January 06, 2017, 04:20:17 PM I'd say turbo failing or collapsing inlet, or some other restriction.

Fueling didn't change, and trims are -0.2% and -5.5%. I'll open her up today and inspect the turbo and hoses. There is also a very low pitch whistle when I accelerate (around 2k rpm).
