C1046Wheel speeds inconsistent

• Renault/Dacia code · ABS / stability control
• Lights a warning lamp

How the car detects it

The speeds measured at the four wheels do not agree with each other. This meaning comes from Renault's tables for its older Bosch ABS/ESP 8.0 units; newer ABS units (for example on Logan II and Clio IV) report wheel faults under other codes. While the fault is present, ABS (and ESP, if fitted) is usually switched off; normal braking still works.

What you may notice
