Whistle it's shocking how those little chips suddenly turn into a crack Whistle

I had a largish chip in my screen, which was looking like it was going to have to become a crack, and then just after Christmas, on one the rare days that there was a frost, I put the heated screen on and crack Mr. Green it did it for me Laughing When I phoned the insurance company they didn't even want to know how it happened... I get the feeling that the roads are disintegrating, so badly now a days, that broken windscreens are an everyday occurrence Rolling Eyes Yesterday I couldn't spell Engineer... Today I are one!

haha sounds about right, fortunately a lot of construction traffic is on my route, I'm sure a stone will flick up at some point Whistle

Any comments on the wind noise? I'm pretty sure its due to the top seal being the problem, does anyone know if autoglass replace it as standard practice? would like to be present when mine is done so I can remove the crappy sealant, don't want yet another leak!

The wind noise is the lower trim, if it's not bedded on a thin bead of glue it howls like a banshee Shocked

Top seal is reused, unless you have a good fitter, then it gets broken and a new one is used Whistle Yesterday I couldn't spell Engineer... Today I are one!

Due to the types of roads here in NZ, we go thro windscreens regularly. I always specify OEM (never a problem) and the fitters always use new clips and replace top seal with one from RR Sport as it is more flexible. Insurance pay without issue. Thumbs Up

Scotland 2017 Range Rover Autobiography SDV8 Loire Blue

As a few of you have seen, from my pics of the Velar, my car has a rather nice crescent shaped crack down at the bottom near the windscreen wiper bus since it hasn't changed since last year when it passed the MOT, imagine my surprise when I get a call to say my car has failed due to "a crack in the lower portion of zone A"!
When I explain this passed last year, the glib reply was "it couldn't have been like that last year, sir otherwise we would have failed it". Because of the shape, it's impossible for it to have got any worse but what more can I do, so it's a replacement time. National Windscreens have been good so far and got hold of the correct Pilkington version, so here's hoping for a successful fitting on Monday Whistle Got - 2017 SDV8 Autobiography in Loire Blue

National chaps did my disco.

Sent 2 guys out to do it and all went well and pilks screen fitted. Only thing is they fitted it a couple of mm low and I mean a couple....Hasn't affected anything and if I wasn't so OCD I wouldn't have noticed. It's not an issue though And all then it's work as they should[/i] There is nothing that can't be fixed with a hammer😜😜

Australia 2004 Range Rover Vogue 4.4 V8 Adriatic Blue

For those 2002-2004 models with original or OEM windscreens, how effective is the rain-sensing? Prior to the screen replacement, I don't recall any issues. Now, with the aftermarket Chinese screen, even on the most sensitive position, the screen has to be almost totally obscured before it will wipe. The trouble is, with rain-sensing, one doesn't get a manual intermittent wipe option.

The problem is that up until the last month, rain was so rare that I can't recall just how good the sensing was. I want to go back to the fitters and complain. I'd like an OEM screen fitted. Ron B. VK2OTC

It shouldn't make a difference if it is a replacement screen, the sensing is done through a small window in the top hatched area of the screen. The sensor stays attached to the car. So long as it can see the outside it should work, the issue comes if the alignment is out or the hole is in the wrong place.

With oem screens there is no perceptible difference from that was fitted as standard.

Mines a '12 it will sweep the window with a few spots of rain in the most sensitive setting. There is nothing that can't be fixed with a hammer😜😜

Thanks NMJ. I'll pull the cover off and check that it's properly located.

Original factory fit is a Land Rover and Pilkington branded screen. OEM from a windscreen repair van is just Pilkington no landrover badge.

Had a pilk screen on both the disco and old FF and no issues at all. There is nothing that can't be fixed with a hammer😜😜

Aha! If I had a Pilkington, there wouldn't be an issue.

I removed the sensor and took a few photos. The sensor mount is not central in the masked area, it's about 2mm off-centre. That may have a bearing on the issue but....

Note the circular clear spot in the mask. That's nowhere near the red sensor window in the rain sensor. I'm not sure of the purpose of that hole or the red sensor window but if it's part of the rain sensor system, surely they should be aligned.

A BMW part.



The windscreen mount. Note the circular hole. They are hard to see in this images but on either side of the central reflective material are two plastic domes - I assume to catch the light from outside. Does this part come already attached to the screen? I thought it might as there appears to be a date 01.06.15 on it.


One one side of the sensor are two devices, they may be LEDs, I don't know. On the others side are two different devices, perhaps photo-sensors. See the last two images below.


Holding the sensor up to the bracket, one can see that the circular hole in the mask doesn't line up with the sensor in the top right corner of the rain sensing box.







Oh, is the red window for sensing ambient light for auto headlights as were on some BMWs? Ron B. VK2OTC

When I had the mirror off, I noticed this sensor in the back of the mirror housing. What is it for? (Pic stolen from another FFRR thread):

That's for the auto-dip of the rearview mirror.

It's designed to sense light and prevent autodip during daylight. IOW, if you have light on both sensors (front and rear) the mirror will not autodip. If you have light on just the rear sensor, it will

Ah, OK. My P38A mirror didn't have the forward facing sensor. Ron B. VK2OTC

I should have looked at RAVE! It is a light sensor.

Quote:
A light sensor is incorporated into the sensor and is used to increase the sensitivity of the sensor when light levels are
low. This feature counteracts the effects of rain on the windscreen affecting the driver's vision during night time driving.


I had a look at the Rain Sensor with Faultmate - and learned something.

There is a Rain Sensor Adaption feature to recalibrate the sensor after a windscreen change. Mine hadn't been done when the screen was changed.
(Later)
Well, after adaption, my rain sensor is working nearly properly again. It is no longer necessary to have it on the most sensitive setting in the hope it might wipe the screen. I've had to turn the sensitivity right down. I suspect it's overly sensitive because the light sensor is receiving no light and the system assumes it's night time.

At least it rained yesterday afternoon so I could test it - the sky was cloudless today. Very Happy

Now, do I go back to the windscreen suppliers and complain the light sensor is blanked off (it's probably the screen for a later non-BMW model) or do I remove the rain sensor and pare away a bit of the mask at the correct light sensor position?

I knew the P38A fairly well but I'm still learning with the L322. Very Happy Ron B. VK2OTC
