DIY CEM (and VGM) PIN Retrieval for Volvo and Polestar

[Saltovez]

I had the same issue with another software "market certificate for IHU" download.  With the latest update of the VIDA, it's not related to fully charged or not. It's about the supplied voltage. I even connected external battery retainer / charger but it still refused to install. 
I ended up installing the software while engine is actually running. Yes, you can do that at least most of the software reloads. It will shut down the engine at the end and finalize the installation.  The important part is that during that finalization period while engine is not running, your battery should be at least %70 full. 

So, you can install the configuration change while the engine is running or you will need external battery charger that supplies 13.5v or more. 
The configuration test does not cost money, it's only 1 cent. $0.01. In my case, I had to ask for refund for the first failed one and re-purchase it second time. Refund process was very quick though, I got refund on my card less than 24 hours I claimed it. 

If it happens next time, DO NOT cancel the process. Just turn on the engine and click on retry or continue. It will give you warning "Do not drive the car" because it will stop the engine as I mentioned above.

Thanks so much for the advice, but I have a Polestar 2. I can't start the engine. The charge is full and on 12V too. Right now the configuration test costs $5 plus tax. A few tries and here it is $20 down the drain.

Sorry, I don't know about polestar that much but shouldn't be the polestar plug-in recharge just plug it in it should stop charging the battery and supply power to other systems in order not to drain the battery. 
It's weird that VOLVO charged you $5, either they have changed the policy and pricing or it's different for polestar cars.

As I mentioned, you can claim refund to due fact that technical issue on the car. Same as I did. Just log on to volvo bookstore, go to my orders and from there you can ask for refund for each order.
