    I have set it to 800rpm and the vibration seems to have gone but i want to know what the standard idle rpm is so i can check if it vibrates now on that!

    840 is about standard but I have set mine at 800. Seems fine at that but wasn't too bad at 840 !

    Running mine anywhere between 740-780 depending on what done to the car at that point. Anything above 810rpm seems to make things a bit 'lumpy'.

    Definitely quieter & smoother, although go too low & it has the opposite effect.

    777 worked for me came from audi set at 840 but its become rough at that idle and injection quatity is very up and down so not sure if changing the idle down can mask injectors on the way out maybe

    I noticed mine was juddering and rev needle was shifting at 800-840 ish due to egr boost hose not being fitted by mechanic properly but now idles at about 875 or very close to that

    Put mine down to 800 for AGES and it ran great, but just had to INCREASE to 925rpm (can't seem to get it higher than that) as judder at idle returned :( ,
    Probably due to cambelt stretching a bit, I will need new cambelt done before summer :(
    I'm sure I heard timing should get checked 1/2 way through cambelt life cycle

    I was sure my mkIV GOLF tdi was @ 50000 and when we bought the A3 a m8 of mine said timing belts should be 75000 or 5years, so I done it at 60000,
    power figs were unknown as I used a powergate unit to change map and car drove great for 40000ish miles on std turbo, but after a problem with my hybrid turbo,map was switched back to standard :( so I can go down custom map route :) :)
