Octavia I 1999 Wischer vorne geht nur wenn es trocken ist (Solution) | Posts 16+

Sorry for giving my feedback so late.

It was the windshield wiper motor! After being swapped with a used engine, the problem has been solved so far.

Buying a new car doesn't make sense for this almost scrap-worthy Octavia with 420,000 km and a 1.6L gasoline engine.

Thank you for the feedback .

So, we can conclude that the wiper motor gets wet or damp from the inside, which can disable any electronics that may be present.
