I have had some of the same issues. I have a 2005 LR3, purchase used in December. My local dealership has had the truck a total of 2 months "trying" to figure out what is wrong with it. They told me yesterday that they had no idea and was refunding my money.
Initial problem was that the vehicle would not start, we purchase a new battery. Vehicle then started, but while driving down the road, the doors would unlock, then I would get a message on the radio "Vehicle Fault: System Shutting Down". When this happens, the radio, A/C and all information on instrument panel go off, and my exterior lights start flashing. There are some occasions where the vehicle will not even start and all of the above issues are occuring also. Today for the first time I am also seeing my Parking Brake light come on.
Any suggestions.....I need help with this truck. It is my main vehicle and it has left me stranded 3 times!!!!

Defective engine temperature sensor wiring?

On another board, an owner had similar problems - 3 would not start, down to the stops, lots of warning lights etc.

It turned out a mouse had got under the black plastic lid and chewed at the wiring to the engine temperature sensor plus a few other sensors.

The engine monitoring systems interpreted the sensor failures as big problems and then reacted to protect the engine and vehicle - primarily by keeping the engine from running and if the engine did start, then down to the stops and lots of lights.

The fix was relatively simple - patch up the wires to various sensors, but one had to find the problems first.

ive actually fixed this specific problem on 3 different occasions at our dealer ship and all 3 have been different. first one was the instrument pack had and internal short. only when hot climates how i found this was i took the ipack out and put the rear of it while car running with heater on to the drivers left side vent allowing all the hot air to direct on the back of the ipack after about 20 min i went over to ipak and gave it a good tap and i was able to duplicate the problem. internal failure of IPAK / CAN NETWORK. now second fix was water damge/ battery explosion on the transferbox module and engine control module behind the battery. and third fix was excessive water damage on passengers side kick panel where the cjb connections/fuse box is located. good luck and let me know how it goes my friends

Range rover

Any help would be appreciated..
2006 lr 3 v6

when i turn the vehicle off, everything starts blinking on and off. The A/c, lights, especially marker lights and door locks all activate for a sec then cut off and back on. All together though. Like someone playing with the door locks and lights. The vehicle only shows a park brake fault, but I have turned it on and off and the parking break works fine. The vehicle drives fine and no warning lights when it is on. But when u turn the engine off, everything starts to "blink" on and off again. Pain in the butt.. I bought the vehicle , but didnt have a manual. any helP>?

Were you ever able to find out the cause and have this fixed? I have the same issue with my RR Sport and it only happens after I take it thought the car wash or a heavy rain.

Mine was doing this and it ended up being the instrument cluster. I replaced it with a used one and re-flashed it with my IIDTool and haven't had an issue since.

So you are saying that you did not have to purchase a brand new one, but just got a similar junk yard display and then were able to put your 3's software back in - as in overwrite whatever was in the old one. What year is your 3? Mine is 2005 and I thought the chips on the instrument panel were not EPROMs - well once only.

I did not think that could be done - I am impressed. I am learning something I did not know.
