My car is a Mazda 3 Hatchback 2015 2.2 litre Diesel SkyActiv-D 150 Sport Nav (LP64 YBY) with a 6-speed manual transmission. I’m screwed right now. Really need help. I rely on my car to feed my family… but it has a supposedly faulty EGR valve which is a false flag aka an electronic issue (diagnosed by mechanic). It’s Causing engine warning light and going on lim mode. I clear the errors with OBD Scanner and they come back within a day. 

Concisely, How can I manually delete the EGR valve from the system? I really can’t afford to have the electric engineer do it. This is 100% legal where I am, as the valve is fine and my Mazda 3 passed the MOT with flying colours. There has to be some sort of device I could delete it with?
