W204/2007/220 CDI
Hi all, wonder if anyone can provide any guidance on a small issue I have.. The car is a 57 plate C220 CDI Auto with 52k on the clock and on very light throttle loadings the revs start to surge up and down by around 150rpm which gives a mild kangaroo effect!

It is the same with cruise on or off but only seems to occur at town driving speeds, not at motorway cruising speeds?

Any help / guidance would be most appreciated! :)

Did you get anywhere with this? My w203 220 cdi is doing the same thing but it only happens once it is warm.
