Bit of a strange one, hoping somebody may have had this problem before!

Came downstairs the other morning, was around 6am and noticed some red flashing lights through the window! I thought what's that so went to investigate and it was my P38 Range Rover (its a V8 97MY if that helps), both the rear fog lights were flashing away. I went outside and noticed the rear fog light switch on the dash was also flickering!

No other faults, it unlocks and locks fine, starts without a problem and no other lights were on/flashing at the time only the rear fogs!

I started the engine and left it running for 20 mins, locked it back up and haven't noticed it happen again but obviously I am not looking at the car 24/7 so I am sure it will come back at some stage.

Checked the connectors in the A post as I always hear people say check them for water ingress, no problem with them bone dry. I then quickly lifted the front seat as not a big job so that I could make sure it was dry down there and that the BECM was not swimming in water! No water ingress so thats a good thing but stumped with what would cause this problem?

Anybody got any thoughts and even better anyone had this problem before and found what the root cause was?

Thanks

Thanks for the tip on the tow bar electrics as I do have a tow bar fitted, would never have thought of that so I will definitely take a look.

Thanks Mark ref water in the lower tailgate, yesterday I did remove the cover and checked all the connections to the rear lamps, bone dry. I also removed the trim panel in the o/s boot as underneath the receiver is black connector which connects the wiring from the BeCM to the lamps, I thought that could be full of oxidisation but it wasnt it was bone dry but was worth a look anyway. Earth point on the os wheel arch which I saw when i removed the trim was also tight and clean.

Thanks for the advice I will take a look at the tow bar electrics when its stopped raining!!
 
Inspected the tow bar wiring this morning, could not see anything wrong. No water inside the tow bar electrical socket either and pins look clean, no nasty green stuff!! Gave it a good spray with contact cleaner nevertheless and I will now monitor to see if the problem happens again. Thanks for all the advice.
