2020 Audi RS Q8 - rust in cylinders?

[ViktarS]

Hello,

I'm currently looking for new / used Audi RS Q8, and today me and the seller went to Audi dealership for a check, so I could make final decision.

Car in question is 2020 (end of November) Audi RS Q8 4.0 TFSI, 55k km on it, from Germany. Was sold to the current owner at 35k km, and he's the owner for about 1 year. Oil change is every 5000 km, with all filters and stuff. Car runs perfectly fine, no issues or errors.

So, the dealer checked cylinders and they found a bit of rust at the very bottom of each cylinder. It's like 1 cm on each of them, somewhere more, somewhere less.

The rest of each cylinder is in a pristine condition.

Below are the photos:









Guys at the dealership don't know what was the cause. The only thing they said is they have seen something similar in imported US cars, when they travelled a long time from US to Europe, because usually trip takes about 2 months to reach final destination. Everything else inside the engine is in pristine condition

So, my question is: how bad is that looking? And what was the issue?

My wild guess is that the car had been several months at dealership in Germany without starting and running, before current owner bought it, but I think I'm wrong.

Any ideas?
Thanks!

Did the owner of that thing mention any misfires that he/she might’ve experienced throughout the year of ownership???

No misfires logged, runs perfectly fine (98 octane only). All services were at the dealership, mileage is confirmed by the dealer.

I would ponder a bad headgasket leaking coolant into the cylinders
