S660 Infotainment Pairing Issue

Interesting. I have an S660 as well, and I had a similar problem a while back. Though I do not remember the exact error code, the symptoms are awfully familiar. Have you tried deleting the device from the car's bluetooth menu and re-pairing it? That seemed to alleviate the problem the first time it happened for me.

Thanks for the quick response! Yes, I've tried deleting the device and re-pairing it multiple times. I even tried with a different phone, and I'm still getting the same issue. Do you remember if the engine light came on or anything else unusual happened when you experienced this problem?

Now that you mention it, I do recall the engine light flickering intermittently. It was quite faint, however. In the end, after trying various troubleshooting steps myself, I took it to a certified workshop. I would encourage you to do the same, especially since the error is consistently stored in the memory. May save you some headaches down the line.

Appreciate the advice! I took your suggestion and brought it to the workshop. Turns out it was a minor software glitch causing the incorrect device pairing, costing me about 45€ to re-flash the system. Thanks again for sharing your experience!
