Hello, look personally I do not agree to cancel it by emptiness or electronic since it is put on ayi to control the recirculation of the exhaust gases (NOX), if it is electronic and you manage to cancel it you can solve the problem but temporarily and this will no longer bother you, but over time you will have problems of, temperature, consumption, minimal march Gases will affect you, this will only give you headaches and affect your pocket, what I advise you is whether they already cleaned it and the problem is not solved and you are sure that it is the EGR to change it for a new one and leave everything as it should be originally.
greetings.
