FWIW, my S54 has this lumpiness, spluttering and occasional kangarooing when cold. For me it seems to be the Eisenmanns as it does not do it with the factory pipes on. I put it down to the lack of back-pressure in the Eisenmanns and not getting the chimney like draw untill they are warmed up. Could be tosh, but its my theory :)

When wamr though, no issues and a sweet sweet sound!

Trundler - prob not what you want to hear but the issue seemed to disappear on its own after posting. I never got the throttle actuators replaced in the end as a result and a subsequent visit to CPC to have a second diagnostics check run showed no errors at all.

I'd say siwilson's last post rings true for me and links to my last on this thread as well about outside weather conditions playing a part. Car is running very nicely at the moment - very responsive - and has been since the warmer weather kicked in.

When the summer ends I'll be monitoring it again but for now all appears ok.

damn!! :)
I get the hesitation and very recently the car has started stalling when pulling up to roundabouts, t-junctions etc: when i drop out of gear the rev's die very quickly, dropping to 0 and sometimes bouncing back to idle, other times stalling.
This morning, after 2 stalls the engine warning light came on - had the code read; appears to be the inlet cam sensor, so will get this and the thottle sensor changed (total approx £230) - tho which throttle sensor will be changed is anyones guess

You have checked the idle control valve ? I had this on another car and it turned out to be a blocked valve. I've also had this on a turbo car where a pipe had collapsed but the pressure held it up until you let off the throttle. Might be worth checking valves / airways etc.
