Fault: Remote control for Audi A4, model year 2006.

Hello, I'm having a problem with a remote control for a:
Audi A4 3.0 TDI Mk. BKN
Born in 2006
The problem manifested in the fact that the remote control had to be re-programmed once a week. What made this even more illogical was the fact that even the spare key itself would forget to initialize. However, it was not even close to the vehicle.
After a few days, attempts, and tests, it became clear that the phone was the root cause of the problem.
This is a Nokia 6230i with Bluetooth, and specifically the Bluetooth feature.
is here the problem.
Further investigation with X... revealed that this issue is not new. One spoke about it,
devices with strong Bluetooth performance, including Nokia, are experiencing malfunctions in the
Range: Can operate with a remote control.
Conclusion: Turn off Bluetooth!
If anyone has a different solution to this problem, please let me know.

Thank you!!!!!!!
