U0131 on Dacia by model: symptoms, diagnosis and fix
The 2nd-gen Sandero (and Logan Mk2) EPS column motor develops a whining or grinding noise during low-speed parking maneuvers, typically at 80,000+ km. Steering function remains, but noise is irritating and can be a precursor to motor failure. Pattern is common across Renault-Dacia EPS columns of this era.
Common Symptoms
- steering whine
- grinding at parking speeds
- EPS warning
How to Fix
Inspect first — sometimes loose mount bolts cause the noise (cheap fix). If motor wear confirmed, refurbished EPS column €250-€450; new €500-€900. Catch it before motor seizes (sudden assistance loss).

Frequently asked questions
What does U0131 mean on a Dacia?
U0131 stands for "Lost Communication with Power Steering Module." This is a network communication code meaning the vehicle's computers have lost communication with the power steering control module over the data bus (CAN). Modern cars link control modules so they can share data, and this code sets when other modules stop receiving expected messages from the power steering unit. The most common result is loss or reduction of power-assisted steering, making the wheel feel heavy, along with a warning light. It generally points to a wiring/connector or power problem at the steering module, a bus fault, or a failed module rather than a mechanical steering issue. On Dacia it is documented across 1 model: Sandero.
What are the most common causes of U0131?
The most common causes of U0131 are: Loss of power or ground to the power steering module, Open or shorted CAN bus wiring to the module, Corroded or loose connector at the steering module, Blown fuse feeding the power steering system, Failed power steering control module, Other module or wiring fault disrupting the data bus, Software/configuration mismatch after a repair. The specific cause varies by vehicle.
