Lexus GS Smartphone Connection Problem

Hey, I've had Bluetooth issues in other cars. Have you tried deleting the phone from the car's system and re-pairing it from scratch? Sometimes that fixes glitches like this.

I've tried that multiple times, but no luck. Is it possible there's a deeper malfunction related to the transmission or ignition system causing interference?

Hmm, if a fresh pairing didn't work and you're seeing error codes, it might be more than just a simple connection problem. I'd probably take it to a workshop and have them check the error memory and fuel system, just to be sure.

I took your advice and visited a workshop. It was indeed related to the incorrect pairing, like I thought, but it needed a system reset which cost 45€ Thank you for your assistance.
