[dsg-svt] SVT coolant flow meter failure at 100% solenoid field

[Brian Eng]

Is the outlet flow meter the one that is closer to the bore?

Maybe it just need to be moved further away from the fringe field? Could either go upstream or closer to the floor.

Seems odd that only one of them failed, since they're identical models.
