EGR shows a flow of 520.0 mg / stroke

[cocktailyogi]

How did you measure it? Is it requestet flow or measured flow?

[Mooti]

Yes, there are 280 on the flow meter for minutes and then shows 520

EGR unplug?

[cocktailyogi]

How did you measure it? Plz desribe your tool.

[Mooti]

Exhaust gas recirculation system, actual value - 520mg / H
680424

[cocktailyogi]

This is correct. The actual value is based on MAF-Sensor. There is no flow-sensor for EGR. Engine-ECU compares request EGR with MAF-Sensor value.
Example: If engine takes 520mg/stroke of Gas and EGR-flow shall be 50%, Actual EGR value will show 260mg/s, because 50% come from Air-Cleaner through MAF-Sensor and the other half comes from EGR.
If EGR is off, all the air comes from Air-Cleaner. Right?
In your picture, Engine wants EGR value of 235mg/s and act value is 505mg/s. All good! This means EGR is off.
You can compare EGR act-value with MAF-value. It is the same. But good to double check.

Now I understand, thank you very much

As the EGR is disconnected this is a fault in the engine. Is it to stay connected?

on this ecu enough to disable it by hysteresis

0 from 18BB30-18BB56
65535 from 18BC26-18BC4C

0 from 1C9F20-1C9F46
65535 from 1CA016-1CA03C

[cocktailyogi]

Do not disconnect egr. Just install my file. Done

[Mooti]

THANKS:-) All is ok

on this ecu enough to disable it by hysteresis

0 from 18BB30-18BB56
65535 from 18BC26-18BC4C

0 from 1C9F20-1C9F46
65535 from 1CA016-1CA03C

May I ask, why it is nessecary to set Hysteresis Map No. 5 to Maximum(65535)? I thought it should be set to zero. Maybe I am wrong, but I would like to know why.
