Hi All,

First post here.

I have a Range Rover Sport L320 2010 with the following error that has just come up:B10AD-87 (2F) Rain sensor - Bus signal/message failure - missing a message

My Auto Lights are permanently on also

Many thanks all

 

That could be the LIN which is the communication from the rain light sensor to the body control module. I would start with checking fuse 31 behind the glove box and making sure it is good and that the rain light sensor is plugged in properly.

 

Thank little green giant. Fuse 31 is: F31 20 Electric window motor, rear left in some documentation I have found. F18 5 Windscreen wiper rain sensor/ambient light sensor appears to be the correct fuse and this didn't have a fuse present at first which is odd as both the Sensor for lights and rain was working fine so I can't understand F18 not being present. Are you sure F31 is for the rain sensor? I will check anyway, just a bit confused by the correct fuse

 

It's very possible I gave you the wrong fuse if you're truck is not an NAS spec. Which engine do you have, or PM me your vin and I'll see what I can find for you

 

you were 100% correct, it was F31 and it had blown. Replaced and all working again thank you! The literature I was looking at re the fuses was clearly incorrect. Not sure why it has blown, not sure I’ll ever know. Thank you for your help
