Customer Question

I have a 2007 XC70 (115000 miles). For the last two months the engine system fault light has been on. My local garage have read the fault codes and as a result I have had a new EGR valve fitted, a new turbo pressure sensor, a new injector on the No. 5 cylinder and new glow plugs. Still the problem persists with the warning light on and intermittent power loss. The car has no urgency and coughs and splutters when I try to accelerate. It was showing as soot filter full but this seems to have regenerated and the readings for soot in the DPF are low - and yet today as soon as I demanded more power it coughed and the engine system light came back on. Will a new DPF (despite the car telling me it's ok) do the trick? Any ideas please as this is getting beyond a joke. Thanks
