Hi,
I've a 2018 Quattro sedan, stage 1 with downpipe and Milltek exhaust. I've noticed recently a slight fluttering (intermittent) from the turbo at low speed , normal acceleration, changing from first to second (auto) - I've not heard it at any other time (maybe I can't above exhaust noise). I'm assuming it's the diverter valve which I will replace. My questions are - which version of the valve is recommended given that the car is tuned and that I may possibly go stage 2 in the future - diaphragm or piston, and, could there be any other reason causing this turbo flutter? There seem to be many revisions to the diverter valve that it's obviously been a problem part.
Thanks.
