According to my IIDTool my car has updates pending for the majority of the modules it can see on the car. Has anyone updated them via IIDTool?

I've read so many stories of L405's not functioning properly after land rover themselves have done the updates I've held off for ages.

Surely whatever updates that are now out there for the MY13 era are stable updates and won't kill the car??

Anyone done it? Current

I installed a software mod via IID on my older L322 to fix a restricted performance problem, it worked perfectly but I was cr@pping myself the entire time that it was happening mainly because I couldn't understand what was happening - it all seems like magic to me. Even with this positive result behind me I wont even consider doing the many "updates" that both my cars have available to them, I believe that if it isn't broke don't fix it.
My approach would be What do I hope to gain? v What can go wrong? If the "trained" LR techs can cock it up how much damage could us amateurs do?
My view would be to leave it alone unless there is something specifically needs fixing but I am a dinasaur who is well past "fear of missing out" syndrome.

If it ain't broke don't fix it I say  Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Thats what I've been thinking for the past year but I'm now thinking what am I missing? do I get anything? what is improved?

I know I have 1 fault code permenantly on the engine that is known to clear with a software update, I've still not done it though. Current

It works fine, I had no issues on my L322, I did however connect my CTEK charger to the battery just in case it took a while. When I did a similar upgrade to my Touareg it took nearly 90 minutes! The last thing you want is a low voltage shutdown mid update. BMW i3 Electric Car

I did quite a few things on both of my previous L322's updates and tweaks. It's the L405 and its highly strung modules that put me off. Current

if you go to a dealer then the cost will be a lot more... ... - .- -.

I was quoted £330+VAT to do the update that I purchased from GAP for £25. Great service, great support, Land Rover appalling support as usual, pay to have problems resolved that were there by design. BMW i3 Electric Car

I updated the suspension compressor (trying to rectify an fault that turned out to be nothing to do with the compressor) and it promptly bricked the ECU, the car went onto it bump stops. It would not re flash! However, some emails with Patrick at GAP resulted in some updated files that got it up and running again, excellent service from Patrick 2010 3.6 TDV8

These vehicles are very power hungry when the ignition is on (which it will be whilst a software update is in progress).
If performing any software updates to the vehicle an external power supply, preferably one capable of supplying more than 20 amps should be connected to guard against the possibility of low voltage causing a corrupted update and a bricked ECU.

JLR specify a minimum of 100A supply while reflashing L405 etc, soon to rise to 125A

Even the L322 was recommended 70A minimum

Our BSU has a display showing the current draw while connected, some of the numbers are scary
