Mazda CX-5 engine check light on, error code indicates egr valve.

Car: Mazda CX-5
Variant: 2.2 L diesel
Model Year: 2016

Categories: Engine & Drivetrain

As noted above. Error code for problem with EGR valve, replacing valve with another (pre-owned) one has not fixed the issue. The light can be turned of in the engine management system but will turn back on in a few days. The light can also sometimes turn itself off but will come on again later. The fuel intake system has been hydrogen-cleaned but this did not cure the problem either. In all other respects the engine runs very well indeed.

Why use a second hand , used part that may be faulty instead of a new part ? Dont know what the fault code is or whether your scanner is capable of covering all systems / modules. The likes of Mazda VCM II are more accurate and usually defines faults better or is just a basic scanner ? , You ever changed the fuel filter on routine maintenance ?
