EGR issue?

[steff95]

Hi 

 

My car suddenly started flashing the coil light and went into limp mode.

I connected iCarsoft which says p046c00 Exhaust Gas Recirculation Sensor “A” Circuit Range/Performance - active/static

Cleared the faulth, started up again, and the flash came back quickly. Now when I scan it says p040300 exhaust gas recirculation circuit / p0403 exhaust gas recirculation control circuit - active/static

Sometime in year 2020 the EGR on this car was replaced at a workshop, so I am wondering; can it really be the EGR again? Is there anything else worth checking first? Because I know it is a lot of work to replace this valve because of the location of it...

 

Thanks in advance

This would all depend if a genuine or a cheap egr has been fitted. As the old saying goes it get what you pay for. 

It could just be a sensor.

True enough. 

Is there any good way to troubleshoot the sensor or do I just have to replace it for testing?

And nothing else to check? I read that the coolant pump for this part sometimes fail as well, but I'm not sure if it would be very obvious in the fault code readings. Or EGR solenoid?
