:iagree: This is what I have to do with mine.

May just need to replace the sensor as long as the optical part of the sensor that is bonded to the windshield isn't coming unstuck/getting bubbles.

With the covers removed (described a few posts up) look at the sensor. You will see a small black rectangular spot at each top corner, press them down about 1/4" with something and the sensor pulls straight back, comes right off in your hand. Really easy to replace. Maybe even just unplug it and plug it back in just to test it first.

Well,just had a look on the sensors bond spot and surely enough there is a huge air bubble.
Was it there for there 2 years since the WS replacement,I don't know..but I am sure I have to get rid of it soon,snow season is about to hit us by the end of the week. :(

Yep, checked mine and it has buble (the sensor is peeling of the WS).

So I might try just unplugging the circuit, but what in the heck is "auto light" function, cause some folks say that unplugging the circuit will disable that "auto light" feature as well but you gain the speed sensing wiper back.

The auto light feature they are talking about is when you turn the headlight switch to the left and the headlights turn on/off automatically.

Got it, never use that; I even had the DRL disabled since took delivery of the car. Thanks.

Mine stopped working too....My intermittent speed doesn't work either. I recently had my windshield replaced so I made sure the sensor that is located inside the casing of the rear view mirror was in good shape. So its not the connection. I believe its the sensor itself. I haven't tried to unplug it to see if I can control the speed of the wipers yet but I will.

hi all ive a 2004 x5 diesel se iv got the auto light function which anytime of the day the auto light switch is active the lights always seem on , so i think thats possibly gone faulty. but also have all the x5 got auto wipers too ? as when it rains iv got to turn wipers on manually, or is that another fault on the car too. so if im suppose to have auto wipers then any ideas how to fix this fault..

will have to check mine too, the shop checked...i had my windshield replaced in Jan.....since then the rain sensor wasn't working....got them to recheck everything today...just waiting on some rain now!! lol

So it actually rained today after i pick up the car...and....no rain sensor...the glass place took it apart and cleaned it...and nothing....i have no idea now...any other suggestions?
