after disconnecting the AGR --> 00522 - Engine Coolant Temperature

1. AGR disabled by blocking and plugging the hose. When the engine is cold, error 00522 - Engine Coolant Temperature Sensor (G62) is recorded. When the engine is warm, it's time to relax.
Motor is the AYM.
Could it be that only a false message is being displayed, because I haven't found a suitable label file for the AYM? Does VAGCOM always take the data from the AKE?

2. Also, the engine is louder at idle when the EGR valve is faulty, is that normal?

3. Where can I get the target values for the AYM?


Otherwise, a great forum. I've learned a lot.

Hi Sulzi

After 522 has the same meaning in all other engines, I assume you have a problem there. Broken wire, misaligned connector, etc....

The engine runs rougher when the AGR is deactivated; this is normal. When you activate the AGR and set it to full return, it runs smoothly like a chamber diesel...
results from the operation of the 'exhaust gas recirculation' system


See you, Gremlin

[Translating...]mit funktionsfähiger AGR kommt bei kaltem Motor keine Fehlermeldung, wenn ich die AGR durch abziehen des Steckers lahm lege kommt auch nur die Fehlermeldung vom AGR und nichts vom G62, das ist ja das komische was ich nicht versteh.

aber schaun mer mal ich werde das weiter untersuchen.
