    First posts normally go in introductions else you could get a free fix and we never see you again!!!

    Your car spec says 0 but you have posted in the Touran section so I've added that.

    Black smoke is unburnt fuel/diesel. Blue smoke is oil being burnt.

    Is your VCDS a genuine cable or a cheap Chinese cloned cable?

    You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

    Sounds like a boost leak.

    You need a boost system pressure or smoke test doing, this can expose splits in hoses or the intercooler you just can't see otherwise.
