Even for a modern VW 10k sounds unlikely, unless there’s some underlying problem they’re not fixing. They claim (of course) that the chain never needs changing, but something like 100k is more realistic - pretty much the same as the belt (at least on my Audi 2.0 TFSI).
Only doing the belt is quick and cheap, while the chain can be a nightmare when it’s at the rear of the engine bay.
Not exactly modern, the car is now about 10 years old. I think it was a Jetta.
