Hi, got the above car Nov last year and had loads of issues regarding "Check Injection" and "Check Emisions" with fault codes P0409 P0487. After 3 EGR Valves DPF and wiring loom modification all done under warranty car seemed fine. Warranty ran out last month and this morning the dreaded "Check Injection" came on with codes P0403 and P0409. Can someone point us in the right direction. Car has done 70k and the last 5k has been mainly motorway by me. It took the dealer 3 months to sort out and much frustration. Run fine for 2 months and bang gone again. Is it likeley to hav blown another egr valve?
