Are you sure the engine is actually running? Perhaps just a series of very loud pumps that are cooling the turbo?

Perhaps they were just fans running, but were LOUD!

It also mentions that if you've been thrasing it, to drive regularly for a few mins, or idle for a few mins, before turning it off (cause it's more than the turbo you need to look after

). But with regular driving, you're right to just turn it off as soon as you pull up

yes and to assist heat dispersing from the engine, raise the hood for an hour or two after a hard drive....

Yeah. You may find the R will crank the fans after you turn the engine off on a hot day. Here in SA I've had that happen a handful of times after driving in 30+ degree heat, and it is very loud.

+1. But there really is no substitute for letting the engine idle for 2-5 minutes if you've been driving hard within the last, say, 5 minutes. The turbo and other components need to cool down slowly and in a controlled fashion; switching off right away can cause temperatures to fall off quickly, leading to rapid contraction of turbo housings, warping and cracking of various critical parts, etc. So you need to be as concerned about rapid cooling as you do about retained heat.

It's nice that our VWs have protection mechanisms built in to prevent serious damage, but I still remember the lurid labels on doors of 80s turbo cars warning of critical turbo failure if you don't do controlled cooling, and so give my car the benefit of the doubt.
