Dear friends,

I searched already on forum about this but nothing which can helpful.

My cluster loose power, everything is shut down, but sometimes seems to works, but oil light and seatbelt light comes on with "low washer fluid" message as well. So I use a delphi diagnosis and I have this kind of problems (see the attachemnts).

RRS 2009 2.7 tdv6

Thank you in advance and have a nice day!

Pull the cluster and clean/check the connector. Strip back the cover on the harness and check for chaffed wires and repair as necessary.

A Quote from an LR3 forum that I was going to do when the weather heats up here in Northern Ontario.
"Often the problems you speak of are just that the plug for some reason is loose in the socket. All you do is disconnect and reconnect. I think maybe the cable feed is a bit short and over time, temperature change pulls the plug from the socket, or at least loosens it so that some of the contacts do not connect any longer.

If that does not resolve the problem, unwrap the first three inches of electrical tape that covers the main cable and inspect the conductors. In some cases, for some reason, (probably too short a cable), the electrical insulation around the individual conductors has deteriorated due to stretching, and hence copper is touching copper.

You will find some of those twisted pair conductors, (yellow insulation), (they are Can-buss wires), and most likely the ones causing all the lights to flicker on and off etc as they tie to the computers.

The fix is just to repair the insulation breaks with 3M black electrical tape, probably the +33 type."

There is also some connectors in the kick panel below the dash on either side that get damp from your sunroof drains being clogged that could cause this issue.

That will the first thing that I will do.
I will keep this topic under update.
Thank you rayodunne!

Hello all, today I unplug the cluster. I looked for broken wires, but nothing. I suspect that is the cluster itself. Also was checked the battery ground but nothing souspicious.

I did the same last week. I'm having way more issue with the truck as time progresses. I now have random alarm issues, bypassed the hood switch and it still goes off. Unplugged the horns for now so the neighbors don't kill me. Multiple ECU communication errors also.
I'm digging into the CJB later this week to see if there is water damage from the sunroof drain and also the connectors in the kick panels. I also have to locate the ground that apparently causes all sorts of issues, see attached.

A lots off errors you have. In my case I don’t have sunroof. I asked for entire cluster to JLR Romania, 1200€ for a new Dashboard. Still I have the issue. Greetings

Cheaper to buy a used cluster and a Gap iidtool BT

Cluster

Gap tool.

The Gap tool pays for itself within a year.

Id also check the canbus connections behind the battery compartment for corrosion. Did you already replace the cluster for 1200 Euro? With out any diagnostic tool you are going to throw parts at this car forever.

These docs might help you in your quest.

Nope, I didn’t change yet. I will buy a used one and I will try to coding it.
I'm currently hunting down a used one myself. A tip below from Pat at Gap.

Pat: "If you do go ahead, first, keep in mind that it needs to be the same model year range, 2004-2006, or 2007+ due to fascia changes. Odometer value can only be raised, not lowered and to a maximum of 262k km. If the car is higher than this value, the odometer value will not be raised.
Once you have it on hand, don't install it immediately. Send me a mail and purchase the fast lane"

ME: "So any instrument pack from 2007+ or do I need to match the part number from my existing pack?"
Pat: "Any from 2007 to 2009 of course will do."

ME: "If I buy one from USA with MPH as primary on Speedometer will it work ok with my Canadian with KPH as primary? The difference won't bother me visually, but just checking."
Pat: "Yes it will work"

I just did a full interior swap, pretty much everything but the carpets and a headliner, in the middle of putting everything back together I wanted to make sure everything is working like cluster nav screen and other electronics just so I don’t have to disassemble again, well everything worked except for the cluster power was there and it would show that that gap tool was connected. I could start the car as well but nothing on the cluster would show up except for maybe one control light and gap tool. Instead of tearing apart everything again I figured that the computers might not communicate with each other and doesn’t send a signal. Main part that fixed it was when I plugged in the wire harness in the center tunnel underneath the shifter. Could be something came loose somewhere else that doesn’t send the signal to it.

The connector you speak of, is it near the cup holders? Possible corrosion from spillages?
All of my errors are pointing to the cluster as the circuits affected do not come in interact anywhere else. Thank you for your input though.

The main connectors are attached more directly underneath the gear shifter. Easy to check.

Sorry to hear this. Have replaced the battery and attached it to charger? All these codes mean low voltage.

if your dinking with car it’s very possible the battery got run down, and can’t recover. There should be a rule “if battery is over 36 months, replace with new high quality before you do anything else and retest”.
You will notice that the first thing the dealer does is a battery test at each visit.

@LegalBrief I don't know if you are responding to me or @Morningstarr
It is a little more complex than a battery. You joined the site 5 hrs ago and drive a 2020 P525 so I really don't know your experience with an L320.
The battery was new last year and is in good health. The issue is sporadic and not constant like a dud battery. The alternator puts out 14.4V at 1500rpm and 13.7-13.9V at idle. I have never been to a dealer as the nearest one is 400 km away, so I would not know their procedures. As for throwing new batteries in vehicles every 36 months, throw me your wallet and I will do just that.

LOL - you can bash me all you want! I have had Rovers since 2000...
That said KISS is a true approach and batteries are the weirdest things, especially as they age.

Questioning your experience with this land rover model is hardly bashing you. I have checked my battery and ordered some testosterone for you.
