Mine on my previous E39s and current 328ci are dodgy at best with a willful mind of their own. ------------- Gentlemen I may not have a brain but I do have an idea Past; E39 540T/E46 328CI/ E39 535/ E39 520/ E36 M3/ E36 318iS jet black Mtech/ E46 320d/ E36 318iS diamond black/ E36 318iS blue Mtech kit |

Yeh must be a common problem. My mates E38 does the same. Mines have never worked since I bought the car... Although there must be some sort of fix out there..

What are rain sensors?
When it rains I turn the wipers on. When it stops raining, I turn them off again.

Rain sensors is a sensor normally located behind your rear view mirror. You can see if you have them by looking from outside into the front, you'll see a triangle shape tinted glass where the mirror joins the windscreen (infared sensor can be seen from out side). Apparently when they work it senses the rain and automatically starts wiping... You can also adjust the sensitivity on the wiper stork, they have a vertical wheel, top being most sensative. If you have rain sensors you won't have intermittent wipers. Which can be really annoying. I hope that explains it... Aly ------------- E46 328ci now sold :(

Are they worth having or just another thing that could go wrong? The wipers on these cars are pretty clever anyway, the intermittent setting is adjustable and the full on goes faster when you do. Don’t get me wrong, I’m as lazy as the next man (autobox) but it sounds a bridge too far for me!

IMHO just another thing to go wrong. However, saying that, I'm impressed though (most of the time bound to break soon, computers always do - like it keeps warning me of a dip-beam failure - liar! ------------- Cats know your every thought. But don't care. |

If you ask me its just another thing to go wrong.. Intermittent wipers are a lot better, and more reliable. My last Bm (E36 328i sport) never had these problems. Although it would be nice if they worked! My mates E38 work really well. ------------- E46 328ci now sold :(

Very true.. I've tried E46 Fanatics and there is no fix unless you unplug your sensor (Get professional to do it) And then you have Intermittent wipers. On another bomb shell Somebody smashed my windscreen Last night!!! wots that all abt??? Am getting it replaced on Sunday.  Gutted.............. ------------- E46 328ci now sold :(

I reckon they're going to have to dismantle/remove the sensor to replace the windscreen so just ask them not to reconnect.
Sorry to hear bout that though...........not heard of people just smashing windows much but then again it tends to be wing mirrors and running over the tops of cars round here  ------------- Gentlemen I may not have a brain but I do have an idea Past; E39 540T/E46 328CI/ E39 535/ E39 520/ E36 M3/ E36 318iS jet black Mtech/ E46 320d/ E36 318iS diamond black/ E36 318iS blue Mtech kit |

| Mine had a problem on the 328, never did get to the bottom of it, the wipers just stopped working on a few occasions, really dangerous, had to remember never to put them on the first click! Wish I'd known you could get intermittent if you unplugged the sensor! |

The sensor system on my 520 and 535 worked perfectly.......however the rest of them didnt so I'm opting for dodgy wiper sensor! ------------- Gentlemen I may not have a brain but I do have an idea Past; E39 540T/E46 328CI/ E39 535/ E39 520/ E36 M3/ E36 318iS jet black Mtech/ E46 320d/ E36 318iS diamond black/ E36 318iS blue Mtech kit |

I was having trouble with mine after the windscreen had to be replaced. I took off the cover and pressed the sensor in as hard as i could. after a while when i knew it was working i replaced the cover and still working. ------------- Dave Ryle  "The power of accurate observation is commonly called cynicism by those who have not got it." -- George Bernard Shaw |

Rain Sensors can be "funny"... 1st thing is to get the sensor reinitialised (properly) - there's a set procedure with a scan tool to do this. If this fails you can try to find out why... Sometimes the screen, sometimes the sensor... Finally - you can Code the car to behave with normal intermittent rather than rain sensor on the Car/Key Memory Options.

All depends on what's wrong... To run a diag on the car and reinitialise the sensor I usually charge €150. At the end of that if reinitialising doesn't fix it I usually turn the function off for people. Some customers do want it working correctly and it can run to hundreds... Even €1k if it needs screen & sensor etc. All depends... Eddie. ------------- BMW & Mercedes Specialist.
