You won't be cracking the CEM PIN of a SPA vehicle with Vdash I'm afraid.

You have 2 options:

• Bench cracking
• VIDA Config Test

Vdash will ingest your log file and decrypt some of the crypt lines of the log and then use the Seed / Key pair they find in this information to generate a PIN using a known method (algorithm).

Now, if you fancy getting your hands on a PIN yourself (Vdash won't give it to you) then you can simply upload your VIDA log file to the tool mentioned in this thread. PINMagic CEM PIN decoder for SPA Once you've done that, pop over to v-spa.net where we're working to open up the wonderful world of Volvo config change to the masses.

By the way, any old ethernet > obd from Amazon will do. Don't spend a fortune... just test it before you start flashing.

Obviously if you're not in an adventurous mood; VIDA (Log) + Vdash + Cash will probably get you what you want.

Happy config-ing!

thanks! can I use VIDA with a 2017 car though?

VIDA 'Online' yes (may not be available in your country... and/or for authorised dealers only).

SPA are all UDS, but yes it gets all the necessary from a server and then uses a device side application to 'convert' the instructions and send them to the car via adapter then read the results.

As it's UDS you don't necessarily need a special program (e.g VIDA) to handle commands, but you won't have any idea what the responses mean.

Example:

1A01 22 F1 06
Which is <ECU> <Cmd (Read)> <What / where to read>
The above just happens to be a CEM read of 'Vehicle Configuration Parameters'

It would give you a response:
Complete Response: 1A01 62 F1 06 06 CF 4D 04 01 02 01 01 02 01 02 04 02 01 02 01 01 02 02 08 ...
<ECU> <Positive response 9+40)> <Response> <Checksum> <Data ... >
Now you're not going to have ANY idea what that response / data means unless you have information from VIDA. VIDA can turn that information into a human readable format:

Checksum: 4D
001. VEHICLE TYPE: 04 V526
002. DOORS: 01 5 doors
003. TRANSMISSION - DRIVELINE: 02 All Wheel Drive
004. ELECTRIC DRIVELINE: 01 Without power flow

007. ENGINE GENERATION VEA2: 01 VEA generation 1
008. STEERING WHEEL POSITION: 02 Right hand drive
009. GEARBOX: 04 AWF22AWD, Automatic 8-speed AWD
010. GEARBOX,TYPE: 02 Automatic gearbox
011. FUEL TANK, VOLUME: 01 71 L
012. FUEL TANK SENSOR: 02 2 sensors
013. PROPULSION TYPE: 01 Combustion engine

015. TURBO CONFIGURATION: 02 High performance
016. POWER STEERING PERSONALISATION: 02 Electro Power Steering, Personalization
017. TYRE DIMENSION: 08 275/45R20
...

That information above is again stored on the server.

'Old' VIDA all the above information was stored in local databases. Now it's 'online'. Frustrating if you're not US based, but blame local regulation for not having adequate right to repair laws.
