Hello and welcome to Just Answer

ideally the next step would be to plug in a scan tool to pull off what ever fault codes are lodged in the system

but with the 'anti-pollution' fault then its likely to be an issue with the Oxygen sensor in the exhaust

So it would be worth disconnecting that sensor and checking the sensor wire and connector for damage / corrosion and you may have to replace that sensor

if when you get the fault code read off and its a P0420 (low cataylst efficency) then before replacing the cat with new then

try a bottle of this 1st

After half an hour driving "anti pollution fault " disappeared by it self. I have no diagnosis reader by myself. Had been two times in the garage they told me different possibilities. Maybe after changing the head gasket and fuel injectors it just needed to run for a while to clean itself.
Thanks

Hello

OK its possible that the O2 sensor was clogged up or coated ? So a good long drive to get some heat into it may have done the trick

might still be worth getting a scan tool plugged in at some point though
