2016 Volvo XC60 Diesel Experiencing Wide-Ranging Electrical Issues

Hey there! Ran into something similar with my 2013 Volvo XC70 Diesel a while back. Sounded like a real electric fiesta, right? My guess was a dodgy battery, but turns out it was something completely different. Visited my nearby garage and the mechanic told me it was a defective cable connection. It was messing with all the vehicle systems, just like you've described. So not exactly a Flex-Ray bus error, but from what you're saying, could well be a cabling issue. Remember, the devil's in the details. Seems like a serious issue, well, because it can mess up with all the electronic stuff in your car. The mechanic sorted it out by changing the defective plug connections and it got my car up and running again. It was a real day saver! So, my two cents? Get it checked immediately but don't worry too much, this stuff happens and it's fixable. Remember to keep us updated. Good luck!

Hey! That sounds like a proper nightmare, doesn't it? Seems like you got saved by a dodgy cable rather than the flex-ray bus issue I was suspecting for my XC60. It's funny how these things never turn out quite as expected, huh? Critical note though, do you recall how much the repair set you back? Just trying to get a rough esti before I take the plunge with my mechanic. And have you noticed any other quirks or odd behaviors since you got your XC70 sorted? Hoping it's a one-and-done fix. Cheers for the help!

Hey! Yeah, it was quite surprising for me as well. Although I was initially wrong about the exact issue, I'm glad we got to the bottom of it and sorted the electric mess in my XC70. As for the costs, they pinged me 155€ to fix the defective cable connection. It felt reasonable considering the symptoms, so I suggest you prepare for something in that ballpark. And my baby has been running smoothly since visiting the mechanic. No fresh quirks so far - looks like they nailed it first time. The suspected Flex-Ray bus error in your Volvo should be fixed in a similar way. I'd recommend you to get it checked as soon as you can so you can hit the road without worries. Hope this helps and fingers crossed for you! Keep us posted. Cheers!

You're a lifesaver! Truly appreciate you for taking the time to respond and share your experience. That sounds a lot more reasonable than what I paid last time around. Also, it’s comforting to know that there were no other surprises after you got it fixed. Hopefully, my XC60 will follow suit! I'll get my beauty to the mechanic first thing tomorrow. Let's see how this cable matter pans out for me. Will keep you updated. Here’s to hoping everything gets sorted without burning a hole in my pocket! Cheers and thanks again!
