I'm with D3Syd.

Chuck the rain sensor wipers in the bin and put it the good old intermittents with dwell. They wipe too often and shudder across the windscreen since there isn't enough water. The sensitivity control does nothing on mine.

I hate them and never use the wipers on any setting except for a manual wipe even in heavy rain.

So what's the solution guys.

Rain sensor variable delay

Caution: BEFORE entering an automatic car wash, ensure that the wipers are switched off- otherwise, they could operate during the car wash programme and be damaged.

With the wiper switch in position 1, the variable delay automatically adjusts the frequency of the wiper operation according to the information supplied by the rain sensor.

You can increase (a wipe will occur immediately) or decrease the sensitivity of the rain sensor, and therefore the frequency of wiper operation, by rotating the delay switch either clockwise or anticlockwise.
If the sensor detects constant rain, the wipers will operate continuously.

I set mine on the least sensitive option (what would have been 12sec on the old car) on the way home from picking it up at the dealers and I have never touched the wiper stalk since Shocked

I love it when the wipers come on after a large puddle or when passing a lorry in the drizzle. Much quicker than I would have been myself.

Might I suggest that people in Oz should simply leave them off Question

Yup read that, and tried it, but as PCH said, the sensitivity control doesn't seem to do anything whatsoever to the sensitivity. It's seems to have only one setting and that is "over-sensitive" Confused

HHHmmmmm...... Don't know then I'm afraid Yen ....mine work perfectly, similar to JMC's comments really. We do get a reasonable amount of rain though....

...maybe yours are just shocked when it rains and get a bit over excitable Wink

Same as JMC - apart from turning up the sensitivity if it's raining and the light levels are low (strangely it works perfectly in daylight or at night time but seems to need one click extra at dawn or dusk)

While the manual says this, they don't work like this. I found this with my RRS too. The adjuster only changes the delay of the rear wipe and does nothing to change the sensitivity of the auto wipers on the front.

Ah ha! A case in the UK. Matt, I was starting to think that LR saved their batch of dodgy variable rain sensors for this dry continent. Wink

My rain sensor is next to useless. All the adjuster does is adjust how quickly they go into max speed. On the auto setting they are way to sensitive, you just have to breath on the sensor and there off at warp speed. Complained to my local dealer, and was told there all like it. Not sure where they get the sensors from, but the ones in other Ford vehicles work fine. Must be like Ducati's, works fine until it rains!

Confused mine work perfectly, they dont very often get to warp speed - believe thats only happened 3 or 4 times since I got the D3.

My LR3 works like this as well. The wipers are rain sensitive but all the adjuster does is change the frequency of the rear wash wipe. Strange!!!

Thinking about this a little though..... doesnt the manual say the rear wiper mirrors the frequency of the front wipers, sooooo if the sensitivity was increased then we would expect the rear wiper to sweep more often. But still with mine the beahviour of the front wipers doesnt seem to change.

Anyone got any other insite?

Looks like no ones any wiser on this issue. It appears that there are cars out there where the system works perfectly and others where the variability is non existent. I wonder whether there is any correlation to the build date of the car? Confused

variability is also speed dependant aswell and the sensor AFAIK also detects a layer of dust aswell as rain (and it does Wink ) which is why some of you may see them operating with no rain.
