Good job. To all of those that have reconditioned their pumps, can you provide live data of the hydraulic pressure decay? I am collecting data from as many people as I can to compare the data. This will help other people that are still experiencing issues even with new components on their HCU.

My present pump in the car having issue with a fault code P1715 (hydraulic pressure loss in system). The pump had almost new accumulator and also new Burkhart motor so I suspect the internal seals are leaking. I've done the resistor mod which I thought was the issue but the culprit turn out to be the oil pressure issue. The car would goes in neutral while driving and at the same time the engine stall.
