The EGR system helps reduce emissions by recirculating exhaust gases back into the engine for re-combustion.
Clogging of the EGR system especially in older models can cause:

Rough idling and loss of power.
Increased engine knocking o r hesitation.
Higher emissions and reduced fuel efficiency.

Regular EGR valve cleaning o r replacement can prevent these issues and improve performance.
