V70 Smartphone Connectivity Problem

I had something similar happen with my V70. The phone wouldn't connect, and the infotainment system was acting flaky. Was the error message related to the fuel system, maybe indicating some malfunction? Did you check the fuses? What about any engine light?

Fuel system or engine light? That's interesting! I didn't see anything directly related to the fuel system in the error codes, nor is there an engine light on. But maybe there's some deeper electrical issue affecting multiple systems? Where were you having issues, precisely?

Yeah, that's how mine started! No engine light, just the phone refusing to connect and some weirdness with the infotainment system in general. Eventually, it got worse, and I had to take it to a workshop. They traced it to a faulty module messing with the communication bus. Best take it to a mechanic before it gets worse!

You were spot on. Took it to the shop, and it was indeed some sort of communication error due to a faulty connection. 45€ later it was resolved. Thanks for the heads up!
