Just to clarify, the person applying for permission to code past the SGW block also has to be registered, not just any Tom, Dick or Harry. 

Yes, that sounds about right. Presumably so they can make it as difficult or prohibitively expensive as possible for indies to get the codes/do the work.

I think there is a common tweak to be able to code the car to 'remember my last settings' but I'm not about to code a lease car and the new acquisition dates from a time before such nonsense 

Edit: it does have an annoying seat belt bong though, from the moment you start it up. I'd like to switch that off!

As I’ve previously mentioned, DIY coding will sadly be a thing of the past with new models. More and more car manufacturers are installing Secure Gateway Diagnostic Protection, which requires permission from and payment to an authorised dealer before any coding can take place. There are various variations of the protection name but they’re usually something like SGW (various manufacturers) or SGF (VAG). The secure gateway diagnostic protection is a digital barrier between the OBD port and CAN bus.

Pretty much every car now is DoIP for the OBD port, there will be a gateway function somewhere for legacy CAN networks (plus CAN-HD, LIN, FlexRay etc) but the protection all sits at the DoIP layer and the gateway and BCM are on DoIP. The biggest factor that will impact the hacking functional changes is the digital twin, this has the ability to spot, flag, and over write and changes.......plus it could also automatically invalidate warranties and disable functions/features

Thanks for the additional information.    Another issue for tuners is OTA updates. If OTA updates isn’t disabled, a remapped vehicle ECU could be reverted back to standard. So, you pop in to Superchips for a remap to gain an extra 50bhp, pay the £300 or whatever, and then an OTA update wipes it out and reverts it back to standard on the way home.

We can do that, as we can see when they have been re-mapped (there is a data dump from the cars at key off) unless connectivity has been completely killed. The only thing stopping us is that it upsets customers but, it gives data for warranty 

Under the new cyber rules (ENECE R155 and R156) loads more is having to be encyrpted, protected, and locked down, so tuners are in for a real challenge  (having seen what most tuners do, it's not as if they do a great job anyway, only fiddling with a few multipliers!)

The problem is, that once a vehicle is ‘flagged’, that flag goes with the VIN, so even if the vehicle is flashed back to 100% stock with factory software, it will still have that flag attached to it.
In my case, my car is well out of warranty so I can do whatever I like to it within reason, providing that I stay within the emission tolerances for the vehicle type, and it’d be of no concern to Audi. If the vehicle is ever hooked up to ODIS (official VAG software) it would raise a TD1 flag, which goes on to the main Audi corporate database against the VIN and can not be removed, even by Audi technicians. The reason it would show a TD1 flag is because the number of flashes/checksums on the ECU would not match the checksum of the ECU when it left the factory. I wonder how many dealers declare that information to a prospective buyer. 
Technology is getting far too clever for my liking.

Setting aside the buying of a flagged vehicle and that not being declared to a purchaser I don't mind about the manufacturer 'blacklisting' the car.

I do very much mind about being barred from tuning it at all with this idea of the car 'phoning home' before it can be modded. Once I've bought something outright, as far as I'm concerned it's fu€k all to do with anyone what I do with it, including the company who made it.

I completely agree.

It is more fundamental than that, tuning with a MAP will need access to the encryption key just to be able to see the data, let alone decode it and upload fresh. That key is only available by the manufacturers secure server and the cyber standards are forcing the data to be stored in encrypted formats, so it is not like you can use a jtag solution to sniff it out either.

You can expect to see more boxes fiddling with the MAP and MAF signals again 

I know VAG have been doing as per us for some years as well, so they will already knoiw via the vehicles connectivity, if it has been fiddled with

I'd honestly be more surprised if there are any out there that haven't been fiddled with

I think VAG were ahead of the game on this, I recall 15+ years ago of VDCI initiated "mods" being disabled at servicing.

Yep, it’s been around a while now.  The owners spent a while doing adaptations to his VAG vehicle, plus a little remap, books his car in to a main dealer for a service and the technician hooks it up to ODIS. The software pings a message to say a later version of firmware is available and the technician hits that button.    So, it’s goodbye to your adaptations and goodbye to your remap. The update flash will overwrite the ECU and the TCU if required, so any increased gearbox torque limits to handle the remap will be gone as well. They probably enjoy doing it ‘accidentally’ on purpose. 
Some owners have taken to taping up the OBD port and sticking a ficking great note on the steering wheel saying “Do not update the software/firmware on this vehicle”. 
If you let an Indy know, they won’t hook it up for an update.
