Engine management light on, fault code stored P0400 exhaust gas recirculation flow.
The fault was cured by adding Forté Advanced Formula Diesel Treatment, after carrying out a 30 mile road test the management light went off.
Forté's Technical Helpline receives over 300 calls per month. This blog shares solutions for garage workshops on common driveability concerns that can be quickly and effectively treated. The vast majority of those identified are caused by fuel and oil borne contamination formed by natural degradation or via the combustion process. This is a fact of life for internal combustion engines where fossil fuels and oils are used.
