carpets at front wet?? I had that bother when the windscreen was leaking. Or move to a damper climate like West of Scotland where everyone enjoys misting windscreens - hence the low life expectancy in Glasgow. Noooo, just a slightly fogged windscreen I've noticed recently. Carpets are fine , Mr t didn't have a filter today. So ordered genuine one from Mr A online , looked at mine today; cleared it out and it's very dark grey. Seamus.....more than likely dark grey as that is the way it started life......dark grey, as there is a Carbon Particaliseded pollen filter, considerably more expensive, that reputedly becomes statically charged when fan sooks the air through it. This in turn reputedly traps more fine particles of everywhatnots, due to static charge. Get an actual good white one......when IT goes grey, it IS gubbered......or wait like Charlie until a bliddy big hole appears in it......sure sign of buggerdity...... |

Well I just rang local Mr T and surprise....
They had a filter so I bought it , just fitted it - lovely clean white new one.
But...
Was just polishing inside windscreen and b@@@er - I've just knocked the rain sensor from its mount.
Metal bracket as well 😔
So I'm left with glue residue on the screen and the sensor and housing hanging loose.
How to stick it back is the question...
No nails.. superglue gel?
Hmmmm

Rearview mirror adhesive or 3M tape probably best at a guess Jamie.

Done it!!!
But , very carefully scraped off original adhesive from black area around sensor.
Did the same for the metal bracket , then cleaned both with white spirit.
Now I've got clean flat surfaces....
Double sided carpet tape !
Cut carefully to pattern and put in place.
Can't even see it , I've done it so well.
Stuck fast now !!
😊

this time of year, a product like the above is well worth getting. When you see how wet they are after a few days you can see how much damp is in the air. Just replacing filters, etc will not do the job on their own, you want to reduce the damp in the air itself. |

Auto wipers are the only thing I think they’ve not got quite right yet. They either wipe intermittently in a storm or psychotic fast in drizzle. That sensitivity switch just increases the level of erratic behaviour.

That sensitivity switch just increases the level of erratic behaviour. So true. Off, Intermittent, On and Very On. That worked fine. Please can we go back to that, or SORT IT OWT!! |

If you go hunting for how they work, you'll find that the basic principle is that the amount of infra-red light received from internal reflection within the windscreen, from an infra-red light source (infra-red LED or LEDs), is used.
Rain on the windscreen will effect the amount of infra-red reflected back. The devil is in the detail, but basically you compare the received infra-red level with no rain (or the level after the first screen wipe, when the system is activated and/or straight after/during subsequent wipes) and act accordingly.
It's a relatively cheap but reasonable-ish method. Never worked on design for them. However, my feeling is that possibly they are affected by daylight (light detector saturated?). Not checked the light wavelengths and detector response involved, so may be talking utter tripe. I do feel that some rain sensors behave better at night though. See if you notice anything similar.
I can sort of see that the received infra-red "no rain reference level" could be possibly be affected by external sources over which the system has no control. You'd normally want some way of subtracting that out. Maybe there is. Dunno.
Many vehicles now have a camera as part of pedestrian detection / auto emergency braking. There's a whole heap of fancy image processing behind it and in theory you could add a rain drop detection algorithm into the mix & do away with the separate rain sensor. Potentially for the VM, saving a little cash (and windscreen real estate). The algorithm/software is almost free, unless adding it means faster (and so probably more expensive) camera processor hardware is required. You have to do the cost analysis of that versus the camera plus cheaper sensor and take into account the cost associated with increased or reduced assembly cost. In automotive, every tenth of a penny counts (but you already know that Ancs).

I find that the auto wipers on mine work pretty well. OK, so they are absolutely useless at determining whether it is raining or not. But once there are spots of rain on the windscreen they are really very good at working out how fast / frequently to wipe. So all I need, and indeed all I use, are the settings Off and Auto ...  |

On the CX5 I can disable it altogether and it just reverts to intermittent. |
