Yeah so the problem they identified was a "sensor" that is located "on top of the battery". So I can only imagine it's some sort of sensor in the Battery Disconnect Unit (BDU) which is the thing that sits on top of the battery more or less under the rear passenger seats. In the VIDA video on removing the battery, there is a process to open up and disconnect the BDU before removing the cover to the main high voltage battery to access to the battery modules.I'm sure you really, really don't want to have to revisit this but have they found a solution?
I haven't got all the detail yet on the exact sensor but I was hoping to get that information when I pick up my car, but due to the repair not being able to get finished I haven't been able to get the car.
And just on that note, I still haven't got any closer to getting my car back. No word on the sealant (this is now more than a month for something that was suppose to be express posted). I've also been in further conversations with Volvo Customer Care here in Australia. They had some meeting about my car's issues from an "overall perspective" the other day. I've informed them in writing that I am open to "all options". Ideally I would like my actual car back and for it to be reliable for once. But at the same time right now I'd be happy just to get my money back and walk away.
