Took my car in the other day for the oil breather and various niggles (Bluetooth dropping, Bluetooth key not starting car, charging level on iSmart changes itself from 80% to 70 or 100%, windows dropping).
Dealer said they had reconfigured some software. I’m still on R33. They may have fiddled with the software but they didn’t actually apply the updates! I only found out by accident when I went into settings to look for updates and it said I needed to restart the infotainment system to apply the latest updates. Moral of the story is to restart your infotainment system if it has been into the dealers.
it’s too soon to say if the updates have cured any problems.
