replacing fuel filter

Hi all Just got a 13 model LWB trafic to add to my fleet and am fitting a aftermarket separ fuel filter to it in place of the factory Renault item



There is a light coming on the dashboard now little spanner I figure its to tell me to service the original filter or water in the original filter some help there would be nice

Wondering if I can disable this function in the ECU with the right tool let me know if anyone has tried this or achieved this
