Exhaust Gas Recirculation (EGR) Control Difference AAT

Translated on 28-09-2026, 18:44.

Hello everyone!

I recently encountered the following problem:
https://community.dieselschrauber.org/en/viewtopic.php?p=85862#85862

There were errors stored in the memory.

550 Injection start control.
519 Intake manifold pressure sensor.
560 Exhaust gas recirculation.

Today, we adjusted the ESP, and values 550 and 519 are gone...

560 remains the same, and the symptoms are still present.

Can someone help me?

Thank you!

Could you temporarily replace the EGR gasket with a suitable piece of metal?
Normally, I'm against it, but it's ideal for troubleshooting.

I'm usually against it, but it's optimal for debugging.

I've tried, but nothing changes.

The problem occurs when starting and when coasting, whether at 50 km/h or 160 km/h. As soon as I maintain a certain speed for a longer period, I lose power when I try to accelerate.

Thank you.
