Had my S3 Revo'd earlier this year and noticed soon after a slight "hesitation/fluffiness" when accelerating hard, particularly in 3rd gear. Had the MAF changed to a brand new one but it still isn't quite right - it's as if the ECU is 'pulling' the timing slightly back. It's been suggested that I should get the people who did it (Fontain Motors) to re-do it perhaps to see if it is a glitch in the downloaded software.
Has anyone else had "issues" of this nature and what cured it?
Also, I did wonder about replacing the hoses.
However, it isn't a misfire more of a very slight brief hesitation - almost a flutter. Hard to explain how it feels. It could easily be one of the turbo hoses being 'sucked in' briefly/sort of collapsing momentarily.
What are the best hoses to go for? Samco I suppose. Which hose is it likely to be if any?
This type of problem seems to crop up often on these forums and it could be one of several things - hoses, the software, spark plugs, coil packs, etc. Surely there is way to tell/diagnose it once and for all?
