Hi folks. Has anyone experienced water ingress affecting front sensors? Whenever I wash the car the inner driver side one has loads of water dripping out the bottom, and quite a lot runs out from the grille below the bumper. Possibly gathering from under the bonnet grille?

Yes I have. Have even taken lots of videos.of the issue. Car has been inspected twice under warranty and they've disassembled the front bumper but found nothing, nor are there any error codes. And they of course cannot reproduce it in warm repair garage. This usually occurs on wet season (around 0-8C when it has rained) , but did also occur few times in -20C weather. 

 

Waiting for it to occur again (it has been rather dry here lately) and will drive to repair shop when issue is ongoing as they got instructions from Skoda tech to be able to see the issue. Total garbage request as I've sent them half a dozen videos of the issue. 

Have you checked the seal around the front sensor? May be it's cracked and it lets water 'flow' inside the bumper... 

Do any of the sensors have a stone chip on them. I’ve seen sensors with bigger chips allow water when raining to trigger the sensor, but then go back to normal operation when it all drys out again.
