3 amigo lights

Hello I have a discovery td5 had some really bad rain and the puddles are like small lakes been out today in the td5 and went through some very huge puddles water was covering the whole car at times then 20 mins later my 3 amigo lights came on the dash got home left it 20 mins restarted all lights off apart from my handbrake light and air suspension light due to spring conversion do u think it could be the water that had come up under the arches with force and made a abs sensor lose any suggestions will be much appreciated thanku

It won't be lose but rather wet.
Let it dry and get rid of the errors and see which ones home back

It can give spurious faults that reset after switching off. If it doesn't readily come back on don't bother too much although I think it will trigger a hard fault after a certain number of potentially spurious ones (ie caused by random unique conditions like water getting somewhere it shouldn't rather than a sensor gone duff or hub bearing on its way out)
