Hi i wondered if you guys could help.

Ive got an 06 Signum 1.9CDTI Auto, Yesterday i was driving it and a warning light came on the dashboard (Car with Spanner standing up in it) this then went off and the engine emmissons light is now on, I called the RAC out and the diagnosed it as a PO400 EGR Flow problem but reading some of these forums i should be experiencing some problems but the car is still driving normal now power lose or sluggishness but the light is on.

Any ideas??
