I have two vehicles with the same syptoms. 2003 307 and a 2002 C5. Both are non intercooler 90hp code RHY.
Both have what feels like a misfire under light load.Brisk acceleration masks it completely. No codes in either car. Injector corrections at idle are all within +/- 5% of 100%. Fuel pressure at idle is around 250 bar and rises to more than 700 when throttle blipped in workshop. Both have clean white diesel in the tanks, fuel filters have been changed but were not excessivly soiled or water contaminated. No air bubbles are visible in fuel line to HP pump.
Not yet watched live data with fault occuring but will try to capture it next week.
Also not sure of system version yet as Sykes ACR comms on all three! I have a Launch on demo, that only offers one verion of SID. Data is same as Sykes on Peugeot but will not comm with any Citroen!
