Well the first thing is 'what the hell have you done there? and why?'
You need to be specific about which systems are reporting the 'U' codes, the B141296 is easy, that's the Quiescent control module, it's a grey box in the right rear quarter behind the trim with some fuses in it - looks like an auxiliary fuse box. - the other codes may be related to loss of communication with it, until you tell us more detail it's impossible to say.

Something was niggling me about B141296 -
Reference SSM72286
Models Discovery Sport / L550
LR2 / L359
Range Rover / L405
Range Rover Evoque / L538
Title B1412-96 Flagged in the Gateway Module
Category Electrical

Issue
B1412-96 being flagged in the Gateway Module
Cause
Under Investigation.
Action
False log of DTC 1412-96 in the Gateway Module and will not clear due to internal software issues. This will not affect the vehicle
performance and is not visible to the customer.
If DTC 1412-96 is identified:
1. Do not replaced the Gateway Module for this DTC.
2. Do not replace the Quiescent Relay Box for this DTC.
I've a feeling there was a software update which just prevented the DTC being set - as the SSM states, there is no loss of function. So just ignore and move on....

You can generally ignore U codes clear them and see if they come back.

Not always - U230055 indicates an unconfigured (or misconfigured, if someone has been 'playing') module, U230062 indicates a configuration mismatch (most likely CCF) Both can lead to the vehicle being unusable.
The key to deciding if they're critical errors is finding out which module they're flagged in and which module (if loss of communication / missing message) they refer to.

As I said clear them and see if they come back if not forget about it and don't worry. If they come back investigate further.
From a more qualified person than me from a more newer landrover based product forum than here
U codes are meaningless and should be disregarded sir... If you start your car with a battery in 90% health then you will start getting U codes as the voltage drops when the starter motor is working... P codes are the important codes sir

I would love to know where this myth about 'U codes' started, certainly all the training I've done across PSA, Volvo, JLR, Ford, VWG, Mercedes & others - most to MT / Diag. tech level, none have ever said 'U codes? naaa, don't worry about them...'
If that quote is from a certain bodger in Gloucestershire, (with no 'qualifications' as such) then take it with a large pinch of salt, he started out as a 'detailer' and lost the run of himself... If he said it was raining, I'd look out of the window to check.

Let's see if the op comes back to us with an answer. I seriously doubt it but let's see I don't mind being proved wrong unlike others people on here

So, according to your source, these are to be ignored?
All (IMO) point to valid issues and would be treated as confirmed concerns for warranty purposes, with corrective action taken and charged out. Certainly not 'clear & ignore' at least two point to loss of functionality, one would qualify for 'further investigation.

in first place I started buying the kit contents polybush for landrover discovery 5 L462 and replacing it with the rubber parts in orange as seen in the photo. i changed the rubber part in the upper swingarm and there was a suspension sensor for the regulation of the hight that i removed and placed it back right because i couldnt work without removing it (maybe i did something wrong by touching the sensor is that right?). after that i saw the error after the diagnosis as i writed in the first thread and i saw in the display that the hight was only available in normal and the driving was terrible. the car was moving like in a ship and the level of the suspension was in the normal hight. the display also showed a sign fault and below it, it says, only normal hight is available. is that enough information for you to understand? i hope yes.
there was an issue on discovery three and four with fitting poly bushes they were too stiff and had too much stiction caused various suspension codes to come to light.
In some cases the actual arms themselves sheared as the bushes would not flex enough.

Well done, you're the first on my 'ignore' list

None of the DTC's explain the 'normal height only' in isolation - which modules are reporting which DTC?
I would check all height sensors are in the correct orientation, have a look on the 4x4i screen, it should show you which height sensor (if any) is causing height reference issues.
Personally, I think that polybushes destroy the ride quality (and as mentioned above, the suspension arms too) I note that you've also fitted adjustable upper wishbones, these may be sitting at a different reference height compared to the standard upper wishbones and be part of the problem.

What about someone who likes to tell everyone how qualified he is how many training courses he has done, how dare anyone have a different opinion to him because he was/is main dealer this, main dealer that.
They trained monkeys to fly space craft with enuff training.
Anyone can copy and paste and post it up it's not very useful. Then to slag someone's else's post off regarding U codes is just out of order but it seems its getting the norm here.
And did the op get back to us ?? Like so many who find them selves in trouble and desperation they hop onto a forum for some help and support and never come back.
Harsh.....no.
