Dacia Sandero II Display Malfunctions: How to Repair Your Instrument Cluster Quickly?
The dashboard of the Dacia Sandero II is a central electronic module.
It displays the engine and safety data from the vehicle’s CAN network.
A failure can immobilize the vehicle and mask critical alerts, making diagnosis a priority for the professional.
Common symptoms of an internal failure
On this model, three main malfunctions are regularly observed.
- LCD display faults: missing segments, black screen or screen disappearing when hot, flickering, restarts, or compound tool that no longer turns on.
- Backlighting issue: the instrument panel remains dark when the lights are turned on, making nighttime reading difficult or even impossible.
- Total or intermittent failure: random shutdowns, erratic needle behavior, and temporary loss of mileage.
Essential workshop checks
Basic vehicle-side checks
Before concluding that there is an internal failure, certain checks are essential.
- Battery and power supply check
An unstable voltage can cause the module to restart.
- Verification of masses
Oxidized chassis grounds can simulate an electronic malfunction.
- Reading fault codes
An OBD diagnostic allows verification of CAN communication and identification of an internal error.
