What can transfer over from 2012 EOS to 2009 EOS?

I am purchasing a 2012 Eos parts car later today and am curious what parts are direct swap onto my 2009 Eos. The car is smashed on left front but I have not seen it in person to see how bad. I am buying it mostly because it has a nice red leather interior. The 2013 is black and so is my 2009.

What I would really like is to be able to use the newer style instrument cluster...

The 2012 is a Lux version with backup sensors, nav, push button start, and steering wheel controls. Would be sweet to swap everything over to older car, but I assume would be a lot of work.

Yes, it is a lot of work, but having a parts car makes it so much easier. If you have a place to park 2 cars side by side you can keep your existing wiring harness and transfer over just the parts you want. You will be a third way there since you are planning interior swap. You have to have a scan tool for a successful swap though. VCDS is a really good option for most of the things. All of the wanted swaps can be done. I can write up short versions of what is involved in swap of each of the systems if you would like.
I may actually attempt to swap most things over if I don't have to replace the full harness. I do have access to VCDS, but for the cluster I don't know anyone with SVCI or VVDI.

I am doing a bathroom renovation currently so just making plans now for the parts car.

I struggled with the immo. problem without a solution I felt confident trying without bricking the car. I have a used working Golf V diesel white full height mfd display and my original red split display with bottom fade. I managed to get hex dumps from each eeprom, but stopped short when I couldn't find the immo factory code you need to use VCDS (You will know what I mean!). I have thought of immo.deleting the ECU, but that leaves you with a tell tale warning dash message at each key on.

For this OP, one easy thing that might work is swapping both instrument clocks AND ECU if the engines in each car are the same? However the car would have the personality (and mileage!) of the other car
The engines are both 2.0T, but are not the same. The newer car has extra emissions parts so the ECU would be unhappy in my older car.

Do you have VCDS? Can you post the All-Scan from it?
I can possibly do that later this weekend or next weekend. Putting the house back together is priority right now and car is over at a friend's shop. Do you need scan of the 2012 or 2009 or both?

Another question; How different are the headliners? I noticed the 2012 had a solid cover that slides forward to cover sunroof. The 2009 has thin cloth that lets lots of light through.

I have a Chinese Gateway module with extended adaptation options. I know from its large single chip inside it's design is based on software emulation. Unfortunately it doesn't send the correct EOS system 'go to sleep' commands leaving the CANbus open and causing battery drain.

There are thousands of V.W binary firmware files for their modules and ECUs. What matters most is access to a search engine that selects which firmware file versions are vehicle and system compatible and which other modules may need their firmware updated or modules replaced. The Ross-Tech wiki has some useful information gathered from others on certain module compatibilities. It's a pretty good source for steering module information. Just look at the plethora of modules by year, part number, firmware and firmware versions to choose from.

Dealers use their online database access to order replacement electronic modules for workshops so they don't have to work out anything for themselves. A genuine replacement module may come with a service instruction flagging this up, or it's written into an updated service procedure. Module firmware is hardware specific. If they add or change IO functions to a module it's unlikely to be 'Upgradeable' or guaranteed to be backwards compatible. If that module is replaced, it's affect on others in the system has to be considered.

The worst you can do playing around with firmware flashing is brick the module, particularly if you don't have the original binary image to go back to.
So worst case can I pull all the wiring and modules from the newer car and swap everything into my older car and have everything work? It sounds like a ridiculous amount of effort, but I am thinking it is always an option as long as I could leave the engine wiring and ECU alone.

I have had zero time to mess with cars as I have been working on the house every free minute I get.

As I have lots of time during my day job to think about what I want to do with the car, I came up with another idea. I am thinking about selling the 2009 Eos and finding a non-running 2012 Eos to swap everything over. I am seeing most auction cars are Komfort, so I would still want all of the Up-model parts off my donor 2012 car.

Would I be on the right track for getting the same model year to make the parts swap easier? Only thing I can think of that would be an issue is the electronics would have a different VIN from the chassis. Would there be a way to change the VIN? They scan the car electronically every 2 years for emissions so not sure what info they would see.

Here in Arizona (and many other states) on 96 and newer cars, they use the cars On Board Diagnostics for the emissions test. A Check Engine Light for anything is an automatic failure. They also check the ECU readiness section to ensure a minimum of 6 (or 7?) of the 8 readiness tests have passed. These consist of Evap, Oxygen sensor heaters, Exhaust readings, etc.

On pre-96 cars they put them on the rollers with a sniffer in the tailpipe.
