My 2015 640d Gran Coupe today developed a computer problem.  
All data (radio stations, phone details etc) cleared and now computer screen switches off after 30 seconds and reboots and that continues throughout my drive.
Has anyone had a similar problem or knows why this might be happening.
I dread to think what it might cost to fix at BMW.
Any help would be appreciated.

UPDATE:

Problem started when I discovered that my phone connection had failed.

In the connection menu I noted that the bluetooth was turned off.#

I turned it on and started to connect my phone.

After 20-30 seconds the screen went blank and the screen rebooted.

It also wiped out all data from the satnav and the radio settings.

It then constantly worked for 20 seconds then rebooted again and again

I managed to get in and turn the bluetooth off 

It is now staying on but my sat nav info has gone but I am able to tune in on radio but cannot save stations.

Dread to think how much BMW will charge to fix all.

If anyone has a fix please let me know

Hi Hilary
Sorry to hear your having problems with your 640d, I've a similar car myself and have never experienced anything like what you describe. Although I have had issues in the past with my wife's F20 116d, which has randomly called people when connected to the car.
It might be worth searching on one of the BMW forums (either UK or US based) as I'm sure someone will have had similar experience, failing that, if you have a good Indie garage nearby, contact them, because as you say BMW will want the earth. As they did yesterday when my 640 had a major service.
 
I hope you get the problem sorted soon.
 
Phil
