The Check Engine Light illuminated on my 1993 Volvo 940 Wagon yesterday and remains on but not flashing. The OBD II code indicated a 2-4-1 code "EGR System flow too low". The engine runs fine and does not exhibit any symptoms associated with this code, (e.g. uneven idling. stalling, hard to start, excessive fuel consumption, high exhaust NOx, etc.) Has anyone else experienced this anomaly? Should I remove, clean or replace the EGR valve? I have not done this job before, is it difficult? Is it okay to still use the car given that it runs fine?
Any advice will be greatly appreciated.
Many thanks,
OnlyVolvo
