Hi everyone,
I've recently bought a l322 td6 which has intermittent instrument gauges. They could work all day, turn off at some point or not come on in the morning. It is the fuel, revs, speedo and temperature analogue gauges. The fuel reads low with the light on. No warning lights on. They can come back on with a ignition off and on reset or need longer. The rev counter seems to bounce a little when started and then settle at 0. Has anyone encountered this before? I've had a search but struggling to find much help. Thanks for any advice!

Resurrecting this thread, because I have this exact same problem on my MY2005 FFRR Vogue.

I have scoured the internet for any information involving this problem, but still nothing real. This thread is perhaps the best gathering of people with this issue that I have seen.

So I have a MY2005 M62 V8 Range Rover which I bought a little over a year ago. This was a problem since the day I bought the truck. Intermittent problem, exactly like you describe it.

Just the analogue gauges, everything else in the cluster works 100% always. Not a dead pixel, not a flickering light. This is the only issue.

To describe how it is for me: Almost always everything works when I start the car, no problems. But then in 1/10 times after driving for maybe 2-20 minutes, the analogue gauges start pulsating, all in the same tempo, and sort of just give up and go to zero and stay there..

Usually this can be "fixed" by stopping the truck, turning off the engine. Restarting the engine. This has a tendency to fix the analogue gauges and wake them up.

The best way for me to call this problem into being, because it is very intermittent, if the analogue gauges are working, stop the truck, turn off the engine. Go do something for a few minutes, not too long just go have a coffee. Then come back, start the engine and drive. Odds are best that the analogue gauges will fail shortly after that. It's like starting the truck, stopping and turning it off, turning it on again, that will increase the odds of this happening. It's rarest in my experience that this happens on a cold start, it's generally good then (not always, but generally)

Some time last winter my alternator started failing, in the sense that it shorted to earth, so the battery was draining faster and faster until it drained every night. At that time, this problem became *very* bad, and wasn't really intermittent anymore. It was more like constant. So every time, even at cold start the analogue gauges would do their dance of death if they even started at all.

I replaced the alternator with a NOS genuine and this improved things a lot, so it's back to being very intermittent.

I went to a "specialist" in car electronics and he couldn't reproduce the problem or find anything electrically wrong with the truck in his 2 hour testing session. He did advise me to change battery, which I did, and well it didn't make it worse -- but it's so intermittent I don't think it made it better either. Hard to tell any difference.

Anyway, this is my story and I hope more people with this issue come forward. Maybe this is just the instrument cluster itself, probably is tbqh it's so isolated to the cluster. But anyone with this issue, or heard of this issue, please tell us and if you have any thoughts

Add to my previous post here above, I recorded a video of how the gauges are behaving, picture worth a thousand words etc:

Have you checked the voltage on the multiple fuses in the passenger fuse box that supply the instrument cluster, when its playing up? They're identified in the owner handbook. I had a few problems with my instrument cluster (not your particular problem though) and some of the voltages were down to about 10V due to a dodgy ignition switch (which actually has 6 electrical switches in it). Fitted a new ignition switch and all good again. There's a how-to in the wiki to replace the switch.

That's interesting, I'll take a look at that. I'll be sure to check back with the results. Many thanks
