Euro spec S6 vs us spec

Anyone know the differences if any between us spec and euro spec S6? New member just picked up a poorly maintained 30k miles euro spec 2008 s6.

It’s all the same. Nothing is different. Even the part numbers.

If it was not maintained well. That is going to be a really big deal. There is a lot of money that can be spent getting these cars to run well. and I mean a lot of money.

The top 10 biggest issues.

10 air filters
9 fuel filter
8 idler pulleys and belt
7. oil seals on the oil filter housing and valve covers
6… coil packs
5… spark plugs
4. PCV and oil separator
THESE ARE ALL A BIG DEAL
3. Intake manifold - it’s probably broken
2. carbon clean - It’s carboned up

  1. fuel injectors - they need to be replaced or cleaned

I asked JHM the same before I got it tuned and the tuner wrote

“ The 5.2 is not component separated per unit per geo location. So this isn’t component factual but things like cold start and fuel variance are a bit different. Slightly but only for the better in say Europe. Performance wise and overall drive-ability isn’t different … “

So I think that’s it.
If you disregard small thing such as the US spec have orange reflectors in the front bumper.

Thanks for the information, highly appreciated
