What does this fault code mean?
The steering wheel module (SWM) has registered that the car is a model without a rear windshield wiper, yet a button for one is present. A wrong control stalk fitted on the right-hand side means the rear wiper button does not work.
Possible causes

What you can do
- 1Check whether the control stalk has been replaced recently and that it is intended for this car
- 2If you have a diagnostic tool: read the rear wiper button in live data and check whether it responds when pressed
- 3Have a workshop confirm that the stalk fitted on the right-hand side matches this car's equipment
Symptoms you may notice2
