2004 CDTi 120 Power Loss - billythechid

Hello

I am experiencing a intermitent fault with my 117k Vectra. Yesterday started the car after a short run and 30min interval but struggled to achieve enough power to reverse or pull away. Stopped engine re-started and it juddered into life with a far bit of black smoke/ and rough running but still virtually no power.

Called Green Flag no fault codes found through their dignostics and when GF chap re-started after 30-45mins fault cleared. Questioned GF technician who was at a bit of a loss.

Any suggestions/ advice would be appreciated.

Car has no DPF. Run on non supermarket fuels. Proper history etc

I always wonder about stuck EGR valves when diesels black smoke.

Updated info: Grey/ sooty smoke not black (partners mis-description!).Idles no probs but won't rev to beyond 1500rpm.

Independant garage running diagnostic monday. Fingers crossed!!
