Just a quick question if I may! I did a scan of my car and cleared a coolant low fault code on a handheld scanner. Was messing about with it and found a 'readiness' test. When I went in to it it has about 7 different tests and it looks like my car failed on 4 egr, evaporation, catalyst and O2 sensor? Is this because I cleared the codes will these sort themselves out or do I have an issue? No fault codes other than the coolant thing?
