We bought a 2024 Skoda Karoq 1.5 SE L back in May this year. Pretty much ever since we've had it, the front wiper will periodically (randomly) wipe the windscreen when there's blue skies and no rain. Sometimes it will wipe once, sometimes three or even four times. It has been doing this seemingly more frequently in the last couple of weeks when we were away on holiday. Driving back from north Wales yesterday. it happened on seven or eight occassions. I've checked the position of the wiper lever several times just to make sure it hadn't accidentally been nudged into the wrong position, but all ok in that respect.

I did a quick google the other day and came across one or two posts that mention the same issue.

Please can anyone throw light on whata might be causing this?

The car is still under warranty, but I'm guessing that if I take the car back to the dealership for inspection, they might say they can't re-create the issue (because it's random and infrequent) and send me away!

Thanks.

In the other posts I have seen for this fault, it appears that a faulty wiper stalk was the cause.

If the stalk was in the 'Auto-wipe' position rather than Off when this happens, the cause can be a dirty screen around the rain sensor behind the RV mirror.

If you have the wiper stalk set to Auto, which mine is permanently set to, the is the occasional random wiper sweep due to the sensor picking up something. You can adjust the sensitivity on the stalk. I have noticed in this heatwave and high humidity that it’s been doing it more frequently. Is suspect that with air con on there might be tiny condensation drops forming or moisture in the air that the sensor picks up. My previous VWdid much the same during the 11 years I owned it.

The other issue with wipers is randomly refusing to switch off or coming on in the Off position but still working normally at the other stalk positions. Usually the only way to stop it is to switch the ignition off or remove the fuse for the wiper motor. Strangely refitting the fuse can fix the problem. I’ve read that this can happen when the wiper motor needs to reset the park position. Finally there is the fault that requires a new stalk, our Fabia has this fault, it’s apparently something to do with lubricating grease on the contacts in the stalk, happened twice last time was 18 months ago.

Just switch off autowipe in the Infotainment settings.

Thanks for that information. Very useful.

This is a fairly common issue on VW Group cars. Usually the fix is changing the wiper switch, but I've seen several posts where people say cleaning the screen where the sensor is stops it, even though they were adamant the wiper stalk was was not in the auto position. I suppose it costs nothing to try that.
