Hi, hope someone can help. I purchased mt Range Rover l405 a year ago and it’s been great. However I did not notice mt fuel burning heater was not working as never had one before. I fitted the module for remote start and set remote climate in gap iid. Remote works so does timed climate now but no heat only fans. I have the following fault codes.
Aux heater water pump open circuit. I guess I just order one and replace.
Windshield misting sensor system internal failure. Does any one know where it is. I have found a climate sensor right of rear view mirror. And I presume a rain sensor. Is there another sensor?
Also heated windscreen no longer working so would that be the misting sensor?

Thanks for any help,
Paul

Symptoms are typical of the heater pump being faulty, others have had this fault as well. Good luck as access is not the easiest.
The windscreen misting (humidity) sensor is the smaller one next to the mirror, again not an uncommon fault.

Thanks, thought that might have been the one. Came up as climate sensor when I googled number so wasn’t sure. Not worried about mechanical stuff but not great at electrical so thanks again for the help.👍

Hi, does anyone know if the last 2 digits of the number an important?
My number
bj32-18d693-ac there are a few on eBay with that number don’t don’t look in great condition. Some also with BA on the end would they work?

I wouldn't bother with a used sensor, especially at the price they are on eBay, you would likely have as much or more luck with the chinese sensors there.
Genuine part is LR058011, about £120 retail.

I can't say for sure if a BA suffix part would work.

Great thanks for the part number.👍
