Wheel Speed Mismatch (Front Axle)
Front axle wheel speeds differ beyond the plausibility threshold over time. Often caused by mismatched tyre rolling circumference or a partially failing sensor.
Affected components
- Wheel speed sensor fl
- Wheel speed sensor fr
- Tyres
Common causes
- High likelihood: Mixed tyre sizes or worn tyre on one side
- Medium likelihood: One sensor drifting
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
