Diagnosis with TECH2:
Read out the trouble codes.
If no trouble code is set, read out the EGR-position-value by warm engine at idle.
If trouble code P1405 is set or the EGR-value is higher than 1,85V, the EGR-valve is probably defect.
-> Install new calibration(as of TIS CD-ROM 43 available) and replace EGR-valve.
