Why do people want iid tool?
This is genuinely not an antagonistic question, but can anyone explain to me why anyone would want/need an iid tool as a D4 owner? I have no idea what they are or do but from what I gather they are a fault reading tool. But is this for preventative measures? Fault finding, before a warning light? Or does this give you the ability to modify your vehicle? Are they more suited to mechanics?
Seems like a bone question, I have been on the forum for a while, but still have not got my head around why they are in such demand when the come up for sale.
The reason is that I have some £ to spend, and SWMBO does not know. I just want to know if this is a good investment as an owner.

Hi,
as recently bought one, my reasons why.
New about £440, s/h fair price £300 as you still need to change ownership so adds £25, bargain £200.
buy s/h and if you want to sell it again they still fetch £300 ish so ownership cost low.
I wanted to program a spare key so £15 for the blank and the IId did it (£60-£100 job elsewhere)
you can read faults to see if anything is starting "act up" so prevention possible.
My aircon was not working, it showed pressure low but nothing else so it was recharged ok and few months in still good.
if you do have a fault it can point to something you can then buy and fit yourself saving £££ on diag cost, or you can then decide to take into a garage if not something you want/can do again saving labour and poss diag cost (they may diag to make sure not un-reasonable)
you can alter vehicle settings so if you run different size tyres (overall size) or if you have a disco that is not level you can calibrate the suspension height to correct.
you can check things work, such as the FBH "before" its cold and needs to work and do maintenance if needed.
it may help if you get a random fault that that puts a warning light on, you can check it, clear it and then monitor rather than a visit to a dealers.
used mine on a FL2 to check the rear pdc sensors, all were audible clicking so working but the IId had 1 sensor giving very odd readings so changed that and all good, saving a few ££.
I have also changed the oil in my gearbox and to get the correct level it should be running at a certain temp, the IId can run live values and gearbox temp is one of them, so helped do that as well.
like many things in the garage its a tool that helps you "Tinker" if you want to but like many of us we already have loads of tools in the garage that we could manage without Transit! 2019

Thank you both, so it (can)pay for itself. A bit like a spare tyre, you will only miss it when you need it.
Thanks! SWMBO does not need to know the cost, and cares less for the garage toys. Nice.
Is it worth buying new. Is there a benefit? If someone has one for a D3 and I have a D4 will it make a difference.
Given the amount of people with them, I assume it’s user friendly??2016 D4 Landmark

Mine managed to get me home from the South of Spain towing our caravan a few years back.
I had it plugged in and the phone open hanging on the sun visor continuously clearing the poxy fault sending it into limp mode.
Once home it decided to behave itself once at our Indy who could find nothing wrong at all
It’s never done it since either as my Daughter now has the D4.
Worth its weight in Gold I’d say.
Also unlocked lots of features in the past on many of my old Discos. And as others have said you won’t loose money if bought wisely

You will make company owners happy if you buy new, but otherwise I see no differencemin second hand if it works properly.
It is VIN locked so, as said you will need to contact company and pay fee for change of ownership for them to unlock it and for you to be able to lock it to your VIN.
No matter if previous owner had D3, you can lock it to D4 no problem.
User frendlyness is personal matter. To me it is intuitive and user friendly. You can download User Manual before you buy it and see how you understand it.
Word of warning: be aware if you want to change things in your car configuration. If you accidently mess things you will have brick on the parking space instead of your D4.

Had my D3 for quite few years now, and the iid tool arrived on the second day of ownership based on comments in this forum. apart from upgrading the halogen lights the iid tool has been one of the best purchases I made - only wish I had bought the blue tooth version back then... Worth it's weight in gold.

Apart from the fault/diagnosis side,
I have added new batteries, heated electric seats, heated steering wheel, rear cameras, changed how hot the seats actually get, turned on park heating, calibrated suspension, changed to 20” wheels, added beeps on unlocking, use the horn as alarm, oil changes (you can raise the suspension so high a jack isn’t needed) and a few other things I’ve forgotten,
Paid for itself easily!
The park heating alone actually paid for the IID as the dealer wanted silly money.A mod a week until I have nothing to improve or add.

I have the old Blackbox Faultmate FCR which doesn't do much of what the IID does (no unlocking, no real time readings etc) but has proven invaluable over 15 years with fault code reading. Suspension problems instantly identified as a specific faulty sensor, other things have been more complex but bringing the collection of codes onto here has usually resulted in a clear understanding of the issue and solutions. Definitely need a code reader for a D3/4 or any modern car in my view, and you might as well get one that does all the extra bits. Haven't upgraded as IID isn't cheap and I'd already got others to unlock the goodies on my car, if the FCR dies will get one then.Tony
