Hey sorry, very late reply here. That was one of the same codes I got prior to changing out the solenoids. Can't say that will fix yours for sure, but it did on mine.

Changing the mechatronics seems to nearly always fix that particular issue. I still haven't decided if it's an issue with the EDS solenoids or a seal somewhere as you suggested. Any way you could get your mechanic to tell you exactly what seal it is? I'd love to know.
