Which is under intake. Once done started the car it was a funny start after a minute the code came on. We had to undo the throttle body to do the job. Is this something related to it? Like a relearn? Or anything in the way if the intake we had to unplug that can cause that code?

Hello,

Fault code B11DB-87 Battery Monitoring Module - Bus Signal/message failure

This fault would be set in the Body Control module, BCM.
Unless you disturbed the positive supply to the battery sensor this should have nothing to do with the repair carried out.

Land Rover has a service bulletin for this fault, see link:

Yes, this is what is strange. I have not touched it. Woke up the next day, started it and it's now gone. Maybe some water had gone over some wires, that is my only explanations.

Hello,

Water could be a cause.
Suggest keeping an eye on it, if it comes back apply the information I provided earlier.
