Hi I have a 2.2 hdi C5 facelift There was no power when cold then engine ran fine after a few minuets I changed the airflow meter with an after market one which made the car run worse and threw a few faults in and limp mode I changed the air low meter back but cant clear the faults on my lexia the fault being particulate filter punctured I know this is not the case Can anyone help

Thanks

hi you have to read the faults before you can erase them. i had the same fault come up at the weekend after i disconnected the maf to clean out the intake pipework

[oneday]

Try reading the faults history and fault logs then erase them I had same problem on the BSI but once I read the fault logs and history everything cleared ok.
