Windscreen - - -
About a month & 800 miles of ownership - have a 6 inch long crack in my windscreen.
Fortunatly its very low down on the passenger side - just up from where the wiper parks.
OK - yes I will need to get it fixed - hopefully at low cost under my insurance (need to check the small print on that)
But I am wondering if anyone has any experience of windscreen fitting companies -

I believe the screen is bonded in, it has a heating element in it & it has all of the camera, (sign recognition) wiper sensor & lighting sensor fixed to it.
I want to make sure I have someone do the replacement that knows what they are doing - not to sure if any of this stuff will need re-calibrating?

Thanks -

Wasn't this an issue on early cars?

Your ADAS ( Advanced Driver Assistance System) will need re calibrating with a new screen, a reputable glass company should include calibration in the replacement process

The windscreen company will either be able to recalibrate it, or of not then a dealer can do it. These systems are very common now so places are used to doing them.

I had my screen replaced by Autoglass at 4,000 miles and they did it no bother, including calibration. I had them use a genuine screen as the car was only a few months old at the time.

l ordered the solar reflective windscreen as this is supposed to be less prone to the cracking issue, but this option now seems to have disappeared from the online configurator.

Update -

Sort of booked in now - I say sort of as I have to wait till the windscreen is availble.
Hopefully that will be in the next couple of weeks.
Will have to be fitted at a 'fitting' center - as yes the camera system will need to be re-calibrated.
Did a little more research in to this - yes a millimetre of error at the winscreen will equal a far bigger error 100 to 200 meters up the road.

Hope the windscreen stays on the current leadtime as with the colder weather now everytime i put the heater the cracks in the screen grow - they are now over 12 inches long!!

Done - fitted -
Turned up at the fitting garage.
Replacement screen was ready on a stand.
Was told it would take approx 2 hours - depending on the glue/resin to cure & the 'calibration'

Went back in under 2 hours - all done fitted, cured & calibrated.

Have driven it home - lane depatured worked (as normal/before), spped limit signs were recognoised as before.
Will check the headlight assist tomorrow morning.

Only thing I was 'dissapointed' with was its not a genuine LR windscreen.
I asked why not - as my appointment was delayed to get the like for like replacement but the fuitting guys said they get that alot.
People are told they will get an OEM replacement - then when they turn up its a non OEM windscreen.
With the 2 big (over 14 inch long) cracks I had - i needed to hget it repalced.

Was amazed how thin the screen is - didn't measure it but i don't think it was over 2mm

One positive.

Maybe the OEM windscreen will be less prone to cracking in the future. l've read of a few where the screen has cracked.

l remember this happened years ago when the Ford Sierra first came out...if you parked with one front wheel on a curb the screen could fracture!

l doubt this is the reason for the Defender screens failing, maybe it's because the glass is so thin.
