FAQ
Are you a Volvo dealer?
No. CM Montréal is an independent shop that repairs Volvo trucks with the right diagnostic tools, as an alternative to the dealership.
Do you work on older Volvo VNs with the D12?
Yes, we still service older VNs. Call us with the year and VIN so we can confirm parts availability.
My VNL is in derate. What should I do?
Write down the fault code and call 514 700-7413. Derate often comes from the DPF / SCR / DEF system, which we diagnose in the shop.
