Futrell Autowerks: Chemical Carbon Cleans, Do They Work On Direct Injection Motors?

Do Chemical Carbon cleans really work? We test one to find out. Testing was performed with a representative of the company/distributor on a 2010 VW Eos w/EA888 Gen 1 motor, 88K. Carbon build up was normal to moderate (exhibiting misfires on start up)

I have seen fellow rs4 owners using this. Then complain in 10k the symptoms are back.
