Its only non sensible if you really believe a car with 40k has issues with carbon build up . The problem this car more than likely has is sticky injectors providing a poor spray pattern due to lack of use and short trips .

Some fuel with cleaning agents and a decent trip will most likely sort this.

It can and does happen unfortunately.

The problem with DI and overly zealous / poorly designed PCV required by modern emissions laws.

I hope we can both agree that these "terraclean" and similar products are a waste of money never the less
It's EGR, crankcase gasses and water vapour all mixed together. A winning combination!

Stop cruising around in it. Give it some proper load and take it to the redline once and again. Just make sure it's warmed up and oil level is ok. Engines believe it or not are happier and healthier when actually doing something.

It can effect power though. RS4 V8 is a classic example

Update; didn't bother with the hydrogen carbon clean thing but did whip the EGR valve off and found it to be full of carbon deposits.

The valve wasn't closing properly which I think was confusing the car's computer, possibly over-fueling at idle and causing a slight pop from the exhaust.

One can of carb cleaner later and it's running sweet again.

That should be fine with a plastic intake manifold, shouldn't it ? smile
