Those are comms "U" codes (Can Bus). Usually these are a side effect of the main problem which would normally be flagged by for example a "P" or "B" code. What diagnostics are you using?yµ (idµ - eAµ) ψ=mψ

I think that might well be hindering your progress, good diagnostics are not cheap but there is a reason.... They work!
I have no experience of Autel, but given the prices reported on here I would reasonably expect it has limited capabilities.
Do you know anyone with a GAP IID? You really need "dedicated" diagnostics for these vehicles.

Only 2 other codes which wouldn't cause my issue are

Agreed, but the question is wether your code reader is "seeing" ALL the logged faults?
If you can get hold of a GAP IID you can dig much deeper via live values and service menu, as well as comprehensive dtc"s.yµ (idµ - eAµ) ψ=mψ

Not sure why this has happened, but did the lock unlock cycle 5th time horn beeps, and it started once, now no cranking or anything. As soon as you put the key in the ignition, the interior lights come on and hazards flash. I've checked and charged battery, checked and isolated the alternator, run vehicle from mine. I've checked and changed the brake light switch. I checked all bulbs and both rear brake light bulbs had blown, so changed those. Checked all fuses and relays, removed fuse box under the engine bay no signs of water or loose wires. Checked earth strap on the O/S wing and no issue found.
Plugged in the scanner and reset, all faults cleared. Still nothing no cranking. Dash reads System fault and suspension fault (car has lowered itself so no concern there). Re checked the codes and got the following:-
U0155-87 Intermittent Lost comms with instrument cluster control module
U0122-87 Permanent Lost comms with vehicle dynamics control module
U0128-87 Permanent Lost comms with parking brake control module
U0100-87 Permanent Lost comms with engine control module/powertrain control module
U0001-87 Permanent High speed CAN communication bus
We sent the clocks of to a repair place in Essex so can rule those as the issue out. There was faults on them which were fixed.
Come to wits end here so any further info or help would be massively appreciated. Spent hours checking things to no avail.
From one desperate landy owner to this wonderful audience.
I recently solved this problem (at work). Lift the rear left side of the car (to access the connectors behind the wheel). Check all wires for damage. Unbutton the connectors. Apply a lubricant (special or silicone). I think that's where the problem is.

Brilliant, thanks for that I will deffo have a look. Just waiting on the clocks to come back from repair shop.

So got the clocks back and its exactly the same. Same canbus issues. The only hard code stored is for the interior lamp circuit, surely that cant cause all this?

Hi
Am no where near as knowledgeable as the other members here so they can correct me if this test would be useful or not
But would it be useful to test the hi/low canbus ohms readings to see if it’s ok
remove the battery , using a multimeter set to ohms and check the Resistance, between
PIN 3 and 11
PIN 6 and PIN 14
Should be 60 ohms on each test
Just clutching at straws and just an idea
Ref ur light error, have u fitted internal Leds
Also read ref the instrument cluster
There’s a plug on the bottom right. Try to move a it a little.
If the problem is from this plug, cluster will go on and off as you touch the plug.
Hopefully u can soon resolve the issue

Hi, Briscoe05
If the dashboard is serviceable, then you need to look for damage to the electrical wiring (can-bus) (yellow-black twisted wires). In the thresholds, in the harness under the car. Watch carefully with your hands and eyes. I'm sorry I can't help you. If I were in the UK...... it certainly would have helped.
