M5 vanos or cps?

Hello, i just cleaned out my vanos solinoids, because i had fault codes. I replaced the o rings and tested them, the fault codes lead to bank 2. When i had replaced them and started it, i got the same codes as when i started. 4B Activation, inlet VANOS, bank 2, raterd valve and 71 Fucntion, inlet VNAOS, bank 2. I took the solinoid board out again, and tested them again. All of them worked, put it back in the car. And then i got two more fault codes. 53 Activation, exhaust VANOS, bank 2, advance valve and 72 Function, exhaust VANOS, bank 2. This time the car started to miss fire and stall. Could it be a camshaft sensor that triggers these faults? Since i have cleaned and tested the solinoids and no codes cleared?
