2.0 Hdi 90 siemens sid801 with hand primer mechanical egr i think.I have a lot of hesitations during acceleration and high fuel consumptionsThere is no right or wrong correction value these look fine to me though
If you click down the bottom it will tell you the range they should be within
EGR will depend on what engine you have they dont all have a mechanical valve some are electronic
This is why you need to tell us your car details including engine code
ive tried and measured air moved to 466 mg egr electro valve turned in 0%Ok EGR should vary when revved but to be honest you may as well just blank it as its simple enough to blank.
Try running it with AIRFLOW/MAF unplugged see if readings differ it may be faulty and if it is this will affect EGR too
