Find expert Volvo troubleshooting guides, diagnostic tips, and step-by-step solutions for common Volvo problems, warning lights, engine issues, and electrical faults.
Volvo truck light control module problems can cause flickering lamps, one or more exterior lights not working, false bulb warnings, intermittent marker or trailer-light behavior, or several lighting circuits failing at once. But a lighting problem does not automatically mean the module itself is bad. On older Volvo trucks, technicians may encounter a dedicated lighting-control … Read more
If your Volvo truck displays “Volvo Link Hardware Failure – Use Paper Logbook,” do not treat it as a generic engine failure. On the Volvo trucks covered by the original service bulletin, the warning points to a communication problem involving the older Telematics Gateway (TGW) and instrument cluster. The exact repair depends on which telematics … Read more

On older XC90s this can involve the key/transponder and immobilizer-reading system, but low 12V power, poor connections, ignition/start-control faults, Central Electronic Module communication, or a starter-circuit problem can create similar no-start symptoms.

In 2026, the bigger buying question is whether a nearly 20-year-old example has been maintained correctly, whether its six-speed Geartronic automatic and AWD system behave normally, and whether any engine noise, oil/coolant leak, electrical fault or … Read more
If your Volvo XC90 radio screen is not working, the first question is which infotainment generation you have. A 2016–2022 XC90 with the earlier Sensus system does not use the same restart procedure as a 2023+ XC90 with Google built-in, and a 2025.5/2026 XC90 has yet another user-interface generation.
