Nope still with the g/f and she is still with her unreliable Laguna (maybe that's a bit harsh as it has been behaving quite well recently after replacing the intercooler,
valve and crank sensor!!)
Turned out that all 4 glow plugs were totally dead! Replaced them and cleared the fault and all is fine since... ;-)
Exhaust Gas Recirculation
EGR is a NOx (nitrogen oxide and nitrogen dioxide) reduction technique used in most gasoline and diesel engines.
EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. Intermixing the incoming air with recirculated exhaust gas dilutes the mix with inert gas, lowering the adiabatic flame temperature and (in diesel engines) reducing the amount of excess oxygen. The exhaust gas also increases the specific heat capacity of the mix lowering the peak combustion temperature. Because NOx formation progresses much faster at high temperatures, EGR serves to limit the generation of NOx. NOx is primarily formed when a mix of nitrogen and oxygen is subjected to high temperatures.
