Will cylinder deactivation cause my engine long-term damage?

My wife has a VW Golf which goes into Eco mode and runs on two cylinders for better economy. My problem is that in Eco mode i can hear the engine note change and feel extra vibration. I do not doubt we are getting better mpg, but is this feature doing long term engine damage?

Cylinder deactivation is a technology that has been around for some years and can improve fuel consumption under light engine loads. The change of engine note is entirely normal and extra vibration is inevitable as the engine is running on one fewer cylinder. There is no reason to believe that it will cause long-term damage to engine, but you can disable the system by using a different drive mode or increase the throttle input.
