Thread: Auto windscreen wiper sensor

Park in the drive at home with the car running and set up the windscreen wipers in auto mode then get out grab the garden hose and spray the windscreen. The sensor is at the top centre of the windscreen directly in front of the rear vision mirror (well that where it is on my D4). You will soon find out if the system is working!

I'll try it right now with a bucket of water

Nothing really happens when stopped, unless it's actually raining, sprinkling doesn't activate it, you need to be moving for auto wipers to work properly, I have ours set to auto all the time.

It's really wierd when they go off and it's not raining, especially on a fine sunny day.

I have a new TDV6, the auto wipers start working with a light shower. It does not need heavy rain to get them to work. I was a bit unsure about auto wipers, having never used them before, however I find they work really well in this vehicle. I generally turn the wipers off if there is no rain about.

Hmmm - I don't like the sound of that

OK - I had the car running with the auto wiper set up. Threw a bucket of water onto the windscreen and guess what! The wiper did one wipe Is that how it should work - just one wipe?

So you know the system works.

Now have a play with the sensitivity control.

My wipers will operate with a sprinkling of rain at its most sensitive. It will continue to wipe as long as there is new water droplets hitting the sensor area of the windscreen.

Depending on how heavy the rain gets it will also go into the high speed wipe mode.

Pprass.
Are your auto headlights working???
I seem to have a fault with both my auto lights and wipers,they are going to look into it on my first service thats due in august.
