My X5 have some problems at the engine.I ve use my scanner and the codes are:
2851 VARIABLE VALVE GEAR GUIDE SENSOR BANK 2
2853 VARIABLE VALVE GEAR REFERENCE SENSOR BANK 2
2866 VARIABLE VALVE GEAR LEARNING STOP ADJUST NECESSARY
2865 VARIABLE VALVE GEAR POWER LIMITATIONS OP HOME
I ve already foud that the problem is the valvetronic , and a friend at the BMW dealer told me to change the sensor and the servomotor.
I need help.
