Any update?. I pulled both solenoids and pistons, exhaust was seized and full of sludge, all clean now and sliding freely. I got an oem sensor and now have gone from one fault to 3, P0369 intermittent , cam exhaust sensor, vanos solenoid mechanical outlet. What I think has happened my sensor is fcuked for 2.5 years, changed vanos seals 18 months ago seals have not bedded in . The car.is now driving very well plenty of lowdown power. I am hoping that my seals are bedding in and the current faults will work themselves out with time otherwise I will be splitting vanos again.
