Hello I am having valvetronic problems with my 2011 BMW 535ix. I replaced the valvetronic after the car died. My solus ultra has the Valvetronic relearn program but it won't run due other dtc's. The dtc's are 133010 valvetronic servo motor activation malfunction, 1F0904 Engine ECU internal fault activation valvetronic malfunction, 133011 Valvetronic supply voltage malfunction. I did pull the valvetronic harness and ohmed it and it checked out. I heard that there is a blue relay somewhere but I cant locate it. Any help would be appreciated.

Anyone have a solution for this ? My car has the same exact problem. Cranks but won’t start, changed the valvetronic motor and wire to it from dme.

Having similar issue. Possible culprit we tried IVM voltage supply to DME no luck. We tried the power supply because relearn was dying mid-flash. Possible fried ECU. Will let you know soon.

I can't say mine was the same problem but similar.
Car was still under CPO at the time so the dealership did it all.
They basically replaced the whole valvetronic system.
Nothing worked until they did the eccentric shaft also.
May not help but that was the solve for mine.
They didn't list the cost but you can imagine.

Blown resistors can also cause valvetronic errors.
