Hi, I have an issue with the EGR system in my 2.2D 2006 plate X-Type. Short description of what happened: Driving along the main road, approached a junction, make a turn to my village, the engine suddenly lost power and went to a limp mode (flashing coil light). I barely made it home. Lots of smoke behind. After some time in stationary the engine would struggle to start and run. Lots of smoke coming from the exhaust. Fault finding: 1. Disconnected MAF - all back to normal. Engine runs as it should. 2. Disconnected/blanked off EGR - engine works normally. 3. Replaced EGR (electric actuator type, no pressure feedback from the exhaust) - no much improvement. The EGR is opening and closing on idle in regular intervals chocking the engine and again, lots of smoke behind. The idle improves a little bit when the engine warms up. The car is drive-able, but a bit jerky and under powered. 4. Replaced MAF - getting about 18 g/s when the engine is idling and the EGR is obviously disconnected. When the EGR is plugged back in, the reading is erratic as expected. 5. Replaced TMAP, only because I thought it measures the BARO too. The BARO reading doesn't seem right. I get BARO between 140 to 150 kpa when in idle or stationary while MAP reading is 104-114 kpa. This should be equal. I cannot find the barometer sensor in my car. How is the BARO measured in my X-Type? 6. TP % position is right. No issue with an accelerator position. 7. Coolant temperature is right. I am getting an ambient after a night. The inlet manifold air temperature is close to an ambient too when the engine is not running. I don't get any fault codes except the EGR related errors when the valve is blanked off or disconnected. Any idea what else should I check before taking it to the garage?
