So I recently had stalling at junctions issues.vcds said all the injector deviations were okay, my specified and actual fuel rail pressure was okay, no codes listed. Changed the tank pump and filter - didn't work. Changed the fuel regulator and that has stopped the stalling but the car is doing regens constantly every drive and down in power. Plugged in vcds soot under 11g , ash/oil 0.9L. no dpf lights but temp goes to 90 from it's usual 84 odd and the fuel economy drops to about 38mpg which I assume is the regen happening. I only drive motorway miles so now I'm thinking there is something else underlying wrong that was showing up a weak rather than failed fuel regulator which then caused my stall issues. Has anyone had anything like this before or any hints on what next to look at.
