These are timing codes. Something is wrong with your timing. This is unfortunately something that will need to be looked at professionally, it is not something that can be rectified at home.
The vehicle will need to be towed, it will not start in this condition.
I hope that is helpful, please let me know if you have further questions, or if I can clarify anything for you.
It has been my pleasure to help today and I wish you the best of luck with the vehicle.

What i need to know is what excactly does this mean P101b
Variable valve timing (VVT), bank 1 - adaptive
and what needs to be done to resolve the problem
The VVT system adapts over time, but since the system is down, it can't adapt. This is being caused by the other faults with the VVT system, you don't have to worry about this code, just the others .Fixing the others will solve this.
You will need to have the car diagnosed using a BMW specific scan tool in order to get more accurate info on the nature of the fault. Timing issues cannot be diagnosed using generic P codes - it is impossible, they are just too generic.
Please let me know if you have further questions.
thank you in advance.
what i wanted to know is what does "P101b Variable valve timing (VVT), bank 1 - adaptive learning" and how to resolve this
I answer this. It means that the bank one vanos is unable to adapt at the current time.
This is because the whole timing system has suffered a failure.
This will be fixed when the other faults with the timing system are fixed.
by the other codes you mean the P1062 and P1050 or what
There is a failure in the timing system that will require a proper diagnosis - you cannot solve this issue without more sophisticated equipment.
The P101b is only coming on because of this other timing failure. Once you fix the bigger problem, this P101b fault will go away automatically.
P1062 and P1050 indicate a problem with your vanos timing system. Once this problem is addressed, the P101b will go away automatically.
Yes it could be.
You are welcome
