Well they do fail in a way i just discovered.
Normally under the gps tst menu the date and time was ok.
Today i discovered the date starts at 01-01-1998. After 10 minutes it goes to 04-04-1999 ro something. So it it's out of alignment. Also the gps fix is now taking 10minutes while it used to be under one minute.

I run an 1998 e46 with MK4 with latest v32 firmware, 13th gen ulf BM54 etc..
I hope they release an firmware update soon.
