OK final update. It was indeed the instrument cluster. Still not sure if it was indirectly related to the medium speed bus.

Here is what went down:
1. Auto service installed new instrument cluster and they could not reprogram it. It turns out it had been programmed, sent back to Land Rover and then sent to my mechanic and was locked down. Land Rover ackknowledged this was a problem in an email they showed me.
2. Land Rover sent a new one, they installed it, programmed it and everything has worked fine since.

I ended up spending about 1200.00 total
60.00 for a tow.
300.00 for them to pull the bus and look for bad wiring. This lead to the discovery of the instrument cluster shorting
500.00 for a new instrument cluster.
250 to install the cluster.

Hope this thread helps someone in the future!

That is a new one for me.

I really appreciated your update.

I have never heard of the instrument display affecting the starting, (well lots of problems I have heard of), so your update was much appreciated.

These systems are so interrelated that a problem in one area seems to transfer to what one would think was an entirely unrelated system.

Got that couple of weeks ago on a jeep wrangler. The ECU said 4.0 when it was 2.4 4 cylinder. Of course the ecu didnt fix the problem but try explaining that to the guys at the independant shop that knew what they were doing.

I used to work on Rovers. Got a question just ask, need a Rover looked at, Albany, New York.

the ipack is on the HS can...in fact it has the terminating resistor for the HS can incorporated into it...how else would the PCM, TCM, etc. tell the driver (via the cluster) it had a problem if it didnt communicate with those modules as well

i'm having the same issues... i've been tearing apart the interior looking for bad wires ect... replaced battery, light bulbs, brake switch, check TCM, ect... nothing... found a post about the instrument cluster so tried "gently" hitting the dash and it caused the issues to start and stop. could it be a loose instrument cluster wire or what?

Update: After a few weeks of fighting with the cluster floating in the car (unbolted and dash surround apart), so when an "episode" happened i could move it around to make it normal again... i finally did some further disgnostics... ie. poking and proding... it appears the connector was very loose (probably throwing off some of the pins), so i wedged some cut off zip ties in there as shims and it appears to work fine now! 2 weeks of driving around ok. i guess that was the problem! just a loose connection! hopefully.

I have the same problem with my 2007 Range rover Sport (RRS) HSE. The tire pressure lights come and go off, the parking brake light is on, and I get this message "vehicle fault, system shutting down (at times when I drive). I suspected the instrument cluster (IC) was bad (based on my reading) and a RRS dealer told me if that is the problem, a new IC needs to be made in the UK specifically for the car and the mileage. I have question, How did you get an IC and who installed it? The dealer told me that a used part will not work for a RRS. Thanks
