MAN TGX 440 2014 mileage 580000 km
Hello, I have a similar situation, after replacing the egr radiator (apparently regenerated, it was damaged because the engine took in the coolant) in some service lights up (smoke with a thermometer) and additionally today the yellow engine light popped up, I know that the smoke light with a thermometer is displayed at high temperature exhaust gas but I do not know in what conditions it ignites and which sensor is the main information provider.
If anyone has a broader knowledge, please provide information, maybe a technical note or a proposal to solve the problem.
