as I know that men like to cheat I give a solution

diesel manufacturers have baptized in the name AdBlue liquid urea to not scare consumers, diluted ammonia name it can be scary,
If you fill your AdBlue to diesel and it falls on your shoes you'll quickly make a difference with the piss, if it is the same I advise you to change digestive brand.
It may be that the euro 7 makes adding a standard catalyst with additional injector another miracle liquid to neutralize the problems with ammonia?.
