This is a really useful thread - thanks !! I'm intending to give it a try on my 2.0Hdi estate, RP number is 9319, suggesting May 2002 build, actually registered Jan 2003. Only concern is that my "throttle" linkage is a cable to the throttle postion sensor body, rather than a motorised one. http://www.ebay.co.uk/itm/NEW-Throttle-accelerator-position-sensor-Citroen-Berlingo-C5-Synergie-dispatch-/131420636464?pt=LH_DefaultDomain_3&fits=Model%3AC5&hash=item1e9947c530 Some suggestion that this rules out retrofitting cruise - has anyone further intelligence on this? Thanks! richjenn13
