Hi, the code was 401, no I didn't clean passage under egr valve, is it hard? Anything else? Thanks a lot for the reply

Remove the EGR valve, spray some carb cleaner into the passage under the EGR valve and let it soak for a while. Use a stiff wire or something suitable used to poke the passage to dislodge the carbon and use compressd air to clear them. Repeat a few times if necessary.
