Rain light sensor issue

Post by Le_Combattant »

Hello everybody,

A month ago, I had some issue with my original Rain and Light sensor (car is equiped from factory).
In fact auto wiper were not working correctly and same for auto light.

I fact, the glass completely crack over one of the two sensor.
I check Part Number: 5Q0955559A

Lucky, I found a brand new sensor (VW original) on eBay for 50 euros.
The manufactured date is the same as my car, September. So the part number is matching my car's production date.

Well received, I install it on the bracket and finish. Auto light were working great but auto wiper no, or I should say: randomly.

When wiper are off, no problem.
When I swith to the first step (auto mode), wipers perform on cycle and stop.

Water is building up and wipers were doing 1, 2,3, 4 etc...cycles even the glass is free of water.

My windshield is clear, no impact on the area of the sensor.
I took care of cleaning the sensor area and no buble of something else over the sensor.

I don't know what to do, until maybe buy a new sensor (maybye the model I received is a defective one) or there is something to do with adaptation (I have OBDELVEN Pro).
