I'd not be surprised if an owner or independent garage or mechanic came up with this before VW took up the idea, it's the type of improvement those who are used to racing or keeping cars come up with as they have the knowledge, experience, attitude and often machinery and/or skills to adapt or make from new.

I am having a similar issue but my car misfires and at low speed cuts out.

Misfires are often but not always from spark plugs past their best. What's the service, maintenance history of the car has it been done in a timely manner. You really need an appropriate scan tool report and perhaps live data to help diagnosis the issue(s) as there can be so many causes to issues like misfires and if you're not use to the 1.0 litre and/or start/stop cars they can cut out or hesitate from acceleration.

Probably be best if you start a new thread on your issue(s) as it might or might not include the subject/outcome of this thread.

HTH.
