    I think its silly to say all cars do it, I've watched 69 AMG's take off crazily quick and smokeless, I have never seen much on the boot of my car that isn't dust (they do dust up quickly) and the old-skool 1.8T in the old Polo GTI is from the 90's (in its original flavour). Putting down a bit more kw and torque (happy to be challenged on that) than the 6R, so possibly an issue or design (to do with the twin-charger design, tiny engine or DSG)

    Yes, you run a richer mixture at higher revs to protect the engine, but then you are getting away from the best performance from the Stoichiometric ratio, so its not the best for the environment or performance.

    When I hear about a 6R GTI burning through oil there seems to be a number of fixes, so I'd assume one of those will help.

    Heavy sooting/oil chunks on the hatch on the Polo GTi is not normal. After having my engine rebuilt, there is no soot at all. 1500km in and no chunks to be seen. I am also getting no oil consumption so I assume they are related.

    I did a clean and after a week it turns to this! around 800kms clocked up so far...



    you can see where i wiped alot of soot with the finger...




    I read that for one person it has slowly resolved so thats what im hoping for, not much oil use, still near the top after 1000kms
