I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
Expert:  Steve replied 7 months ago.
that is not related to your codes.
Expert:  Steve replied 7 months ago.
the most likely causes of what you are experiencing is a faulty key or failing starter
Expert:  Steve replied 7 months ago.
other possibilities include a faulty brake light switch, trans or clutch switch, or immobilizer issue.
Expert:  Steve replied 7 months ago.
I would start by trying a second key and then have the starter checked out
Expert:  Steve replied 7 months ago.
if those both check out you will need to have the can scanned with a factory BMW scan tool when the issue is present to validate the cause.

the starter is new, and I have new ignition switch
Expert:  Steve replied 7 months ago.
the starter could be defective, although that is unlikely. if the starter is not the cause the rest of my answer stands

can you give more info on this, trans or clutch switch, or immobilizer issue.
Expert:  Steve replied 7 months ago.
do you have auto transmission or manual?
Customer: replied 7 months ago.
automatic
Expert:  Steve replied 7 months ago.
the transmission needs to send a signal to the car that it is in p or n to enable start. if the switch that signals this is faulty, start is prevented. you can also try starting in neutral when this happens to see if anything changes.
Expert:  Steve replied 7 months ago.
the immobilizer is what senses that they correct key is present (via computer chip in the key) then signals the ECU to enable start. if the immobilizer or its antenna that senses the key is faulty, the car will not start

immobilizer has no problem was checked by bmw but wanted a lot of money to repair the ,car
Expert:  Steve replied 7 months ago.
BMW would need to check it when the issue was present to know for sure if the issue was the immobilizer or not.
Expert:  Steve replied 7 months ago.
if BMW has identified the cause, I would have to defer to whatever hands on diagnostics they have carried out, regardless of quoted price.
Expert:  Steve replied 7 months ago.
I have provided a list of the most common things that will cause a no crank no start. if some have been checked, that is fine, the rest need to be checked when the issue is presenting itself.
