    MK6 1.4TSI inconsistent power

    Hi,
    I have been having an issue with my 118tsi where it feels that it is leaking/low on boost. I put my foot to the floor and it very slowly builds power and then it kind of fixed itself for a while and inconsistently comes back, this problem doesnt happen all of the time but on the rare occasion it does it sucks. And it usually happens after i have been driving semi hard for a while. I heard this may be due to the stock diverter valve failing so i bought a gfb DV+ but that hasn't seemed to have helped. Does anyone have any ideas what could be causing this problem?
    Cheers!

    Leaving this here to help you troubleshoot. I'm guessing it might be the supercharger clutch.

    Hi Lee. I read through the attachment and it says that the supercharger uses a "maintenance free magnetic clutch." Im hoping this isn't the issue as it sounds expensive.... do you know if there have been cases of these clutches failing?
    Thanks for your help

    Yes they fail quite commonly on that engine

    I had 3 clutches replaced under warranty during my time.

    Thanks for the responses guys, is it best to go OEM or are there any aftermarket parts that are better?
