AGR errors

Hi,
Leon 1M, ARL engine, manufactured in May 2004.
Everything is as original as possible.

Check engine light is on, and this is the error code.


Address 01: Engine
Control unit part number: 038 906 019 KG.
Component and/or version: 1.9L R4 EDC 0400SG 5342.
Encoding: 00002


19586 - Exhaust gas recirculation system: Limit exceeded.
P3130 - 35-10 - - - Sporadically.

Readiness: 1 1 0 0 0

I suspect either a weasel bite or a faulty AGR valve.
Okay, so my question is: since I'm on the road and can't fix the problem right away,
Is it okay if I keep driving with this error for a while?
Does the MSG modify any values due to the error?
During operation, I didn't notice anything unusual.

Nana, someone has been messing with the adjustment channels .

If the dataset is original and the reason for the "playing" (likely referring to unusual behavior or noise) is a blockage in the EGR pipe, then the cause of the error has likely been identified.
If the dataset is from me, please set the adaptation channels back to the default (32768)); any further changes would be unnecessary and counterproductive.

Nothing major is likely to happen in the short term. In the long term, a stuck VTG (variable turbine geometry) is possible due to excessive soot/overheating caused by a mechanical defect in the EGR (exhaust gas recirculation) valve. In the latter case, prolonged full-throttle operation should obviously be avoided.

Best regards, Rainer.
