Hi everyone,

I am currently using a VDD dongle on my Volvo V40 D3 (5-cylinder). I've started the CEM PIN decoding process and I would like to clarify a few things.

During the initial phase, I heard several relays clicking, fans spinning at high speed, and other strange noises coming from the car modules. After a few minutes, the car restarted itself automatically and the progress bar on my phone disappeared.

I have a few questions regarding the VDD-only process:

Can the VDD dongle complete the entire PIN decoding process on its own, without ever needing to connect a DiCE cable?

Does the decoding happen automatically in the background while I use the car for my daily driving?

Is it necessary to keep the car on a battery charger/maintainer during this "cloud decoding" phase with VDD, or is that only required for the DiCE "brute force" method?

I prefer the VDD method to avoid leaving the car stationary with a laptop for many hours, but I want to be sure I'm doing it correctly.

Thanks in advance for your help!
