Datatek, thanks for your input.
I would be interested as to why you have mentioned the rear left quarter? Under the car or inside the car?
I can say I have been chasing a trailer electrics fault and found a broken wire in the trailer harness ( car underside side rear left quarter behind the bumper). When I purchased the car it did not have any mud flaps and I thought that water would get into that area. As you know we have had a lot of rain and it’s very conceivable that damp would be an issue in this area.
What are your thoughts?
Cheers

In the left rear corner in the boot behind the trim there is a lot of electronics, infotainement etc. Because of the stupid design linking critical and non critical systems on a common data bus, damp can cause many problems. Water ingress there is a common problem, Land rover's fix is a piece of plastic to the deflect the water but that does not stop condensation.

Have you checked the brake light bulbs are working? A failed bulb can also cause issues sometimes.
Hi Nodge68
Thanks for your input. Brake lights are working perfectly. Bright as a button and steady as a rock.

It was worth checking. I had a failed brake light bulb cause a transmission fault message on a D3 not to long ago.

It has finally stoped raining here in South Wales so I have managed to check the rear left compartment electrics. Without doubt there is a dampish feeling to the compartment but nothing significant.
The fuses for the trailer wiring were easy to check. I found the bottom 2 yellow 5 amp fuses were suffering from a white powdery corrosion consistent with other electrical corrosion I have come across in the past. The bottom 5 amp fuse is the number plate light and rear left hand tail light the next fuse up also 5 amp is for right hand tail light.
Disappointingly not the break light circuit though, I think!
I will check over the weekend to see if it has cured my HDC fault. I am not hopeful.

Datatek, do you have any specific modules in mind. Can you point them out on the picture?

Well done Bison and thanks for posting your solution even though it took a while I’m sure many people would look to the end of your thread.
Cheers Tricky.
Hi Bison
Sorry to resurrect your old thread but....
Thanks for your endeavour here as this post has eased my anxieties somewhat.
2010 3.tdv6 sport. 130k miles. 2019 front end damed but repaired. And ran since. Stamped service book bit have my reservations about the latter services so first thing I did was service it.
I have VERY similar issues and symptoms as you reported.
Had it 3 weeks was fine apart from front passenger side suspension always seemed to sit ever so slightly higher. Couldn't tell usually but the 4x4 display seemed to suggest this.
Compressor kicked in some mornings but nit noisy. So bought car anyway thinking ill get that looked at.
Changed all 4 tyres on Saturday there and went for a jet wash after. The black circles guts out the car into offroad mode however left the car jacked up using 2 trolley Jack's at the front for over an hour....as they were shirt staffed. Context....
When fitted I drove off fine. Went fir a power wash and all was OK on the new tyres.
The Monday morning having not really driven it much I went to go to work and within a minute I felt a dead spot while accelerating. Almost like a bad fuel filter feeling I've experienced before. Stopped at a junction I tried to pull out and bing bong similar warnings appeared as you got. Stability control unavailable, park brake fault, gearbox fault and emergency brake assist unavailable drive with care. (Yellow)
I was able to continue albeit felt the car losing power under load. Got the car safely to a stop and turned it off and back on and the errors were gone but the power loss remained. The warning have appeared again once on route to my mechanics but were not on when I got there.
Unfortunately my mechanic only has a snap on code reader and after an extensive read , took 10 minutes to read the modules gave me nothing for suspension but a LOT of communication codes with various modules, like you got. Key fob, fuel level, fuel filter to name a few (I'll get a photo next week).
Battery tested and other electrical checks and mechanic states all appears normal and he has suggested I start with a new fuel filter (Mondays job)
I've sent him this thread as this feels worryingly similar given the suspension symptoms I was seeing before the catastrophe.
This gives me hope I've not bought a complete lemon as otherwise its a nice jeep that seemed to drive very well for a high miler.
My issues will.be getting it safely to a landrover specialist able to recalibrate the ride height as the closes one is 16 miles from me on fast A roads and don't really want to risk losing power.
But figure I'd give it a try was this a reasonable priced job?
Thanks again dude.
Also, after the code read where the ignition had been on for around 10 minutes or so I got the battery warning, low battery please start car. Which is why I asked him to check battery but he assured me its fine. That was my first thought as all these errors appearing suddenly stinks of undervoltage. Particularly as it drives ableit not with full power but no LIMP mode warning etc
Cheers
