    1.8t turbo chatter

    My QTS has developed turbochatter/ a dump valve sound on lift off. I know that these engines aren't meant to sound like this so what could be causing it? Worn Diverter valve?

    The car is feeling slow also, not sure if it's connected though as could be another issue.

    Standard 710 iirc from Audi from the 225 BAM engine or Forge 007 if you want aftermarket.

    007/008 waste of money. I have a revised 007 on mine, no leaky, but only cos it was fitted when i bought it. I'd go OEM given they are £30 and last 10 yrs or more and hold up to 2 bar perfectly

    only if it's under about 4 mnths old, otherwise contact Forge for the revised piston kit. I had mine for free no questions asked.

    I think the Forge one is a decent option, expensive bit of bling but i always prefer metal over plastic.
    the placcy one I had introduced a bit of hesitancy responding to quick decel/overrun - acceleration
    never had that in 8 years of 007 ownership
