Hello everyone,
I'm French.
I'm happy to join your community.
I own a beautiful V60 B4D from 2024.
I'll be contacting you with various technical questions, as I'll be working on the car myself, given that Volvo service in France isn't very competent.
Thank you for your help in advance.

UPDATE – SOLVED

The problem is fixed. D5T5 support confirmed it was a VDASH glitch that prevented CEM configuration changes from being applied. After their fix (03.11.2026) everything works. Thank you, Pavel, and thanks to everyone who offered advice.

For anyone with the same issue (P2, import car, trip computer still in mpg / °F):

Charger connected, ignition position II, engine off. Car configuration → Others → Service interval → "User defined in DIM" → APPLY CHANGES. Detect vehicle again and check that "Current value in the car" really shows "User defined in DIM". Don't trust the green "All items are processed" alone. Only then, in DIM: Temperature units to C, Trip computer units l/100km (EU), DIM service interval (km / months).

If DIM returns NEGATIVE [22] – Conditions not correct, the CEM still isn't set to user defined. If the value keeps reverting and SOFTWARE history shows every attempt as "CEM RESTORE", contact support – it's not your fault.

Hello,

I own a 2016 Volvo V60 P3 with the D4204T9 engine.

I am experiencing problems with the SRS/airbag system. The SRS control module (part number 31429515) has already been repaired, and communication with the module has been restored.

However, several fault codes remain relating to airbag and seatbelt pretensioner circuits, as well as a low supply voltage fault.

I am looking for a workshop experienced in Volvo vehicle electronics, VIDA diagnostics, and troubleshooting the complete SRS wiring harness, including connectors and wiring connections.

Could you please let me know if you can carry out a complete diagnosis and repair of this system?

Thank you in advance. I look forward to your reply.
