My 2011 x5 35i started like normal today.
After a few stops, it didn’t want to start. It sat for 30 min then started again.
These are the 2 codes that pop up.
2E0F: Valvetronic system deactivated.
2D43: Valvetronic system adjustment range, faulty range check.

I tried to calibrate it and I just hear a rapid click, but the scanner says “operation successful.
The codes do not clear at all.
Slight whining noise when I start it and 2 rapid clicks when I turn the engine off.

I’ve read it could be, dirty oil, mhd tune, Valvetronic motor and Valvetronic shaft, or battery.

I’ve had no battery issue. I will measure cca/voltage to verify the battery is good.
I am due for an oil change so I will do an oil flush and change it. I do have an mhd tune, but I’m not sure if that would cause it? I’ve had the time for a couple of years.

Any other info on this before I replace the Valvetronic motor?
Odds of Valvetronic shaft being bad?

Thanks.
