Recall Question ??

[hbeing]

Went to the dealer for my 5K service, oil change and tire rotation on an '08 2.0T Avant. The service manager told me I needed a recall done and he wasn't sure what it was.
When I went back to get it he told me they had to order the parts and I would have to come back, but he still didn't know what it was about,no big as I get an Audi loaner.
So the invoice says 91D4 recall, parts ordered.
Anyone know what this is ???

One more question, anyone know how the rain sensors work (besides good)
just wondering where they are and how they function.

Thanks
Peter

The rain sensors turn on by putting the wiper selector (on right side of steering column) in the 2nd position.

In other words, 1st position would be OFF. 2nd position is one click up (rain sensor activation), 3rd position is one click up (slow).

Positions:
4: High
3: Low
2: Rain Sensor Activated
1: OFF
0: Mist (this is when you push the selector down to run the wipers once real quick. The selector goes back into position 1)

(3 and 4 might be something else, there might even be a 5th position. I don't know because I just leave mine on Rain Sensor or Off all the time)

Then you control the sensitivity by moving the toggle switch that is on the wiper selector. Selector down is least sensitive, up is most.


Hope this helps.

I believe the sensor is in the rear view mirror housing on the inside of the windshield. Not sure how it works though... maybe it's a voltage and rain lowers the resistance.

Infrared light is shot at the windscreen by the sensor, rain on the glass means less of the light is reflected back. Some dude with a propeller hat worked out at what point the loss of return light means its raining

LOL. Someone give that guy with the propeller hat a thumbs up.

That's odd , it's an A4, I found the A6 recall, I'll have to pin them down on that.

That propellor head was really thinking !! Sometimes mine come on for a cycle or two when there is no visible moisture so I was wondering.

Exactly correct. This is how it works. If the area where the rearview mirror connects to the window is too dirty, your wipers will start going on at random times (when there is no rain). Keep that area clean.
