Year of Manufacture *: 2008 Engine Size and Code *: Z19DT ( Optional ) Scanner Used: Tech 2 ( Optional) Fault Codes: None
This car had a blocked DPF replaced by a local garage who then asked me to reset the DPF counter to stop the glow plug light flashing. This one duly done and all seemed well. 200 miles later, glow plug light is flashing again, no fault codes stored but DPF is shown as being 154% blocked!! Reset counter and check differential pressure feed back which showed no unduly high back pressure issues. So, sent it out again to see what happens. Another 200 miles later, the light is back on, no fault codes stored but DPF again shows 162%. The car drives fine but maybe a bit smoky. I have checked the EGR via diagnostics and it appears to be working. MAF with EGR shut - 54 Kg/h, EGR open, MAF drops to 12 Kg/h at idle. A road test under hard acceleration shows a maximum differential pressure reading of 11 KPA @ 1.04 volts. I don't understand how the ECU calculates the DPF condition but I can only assume that it uses the reading from the pressure sensor which appears to be ok. I'm not sure where to go from here!
