Water in Fuel sensor

[Lord Toocan]

Hi.  On my 2018 CR-V, the water-in-fuel sensor came on about two years ago. I was 400 miles from home; the Edinburgh Honda dealer was useless so I called mine at home to ask what I should do. It was suggested it was probably a faulty sensor so I returned safely home. Weeks later at the next annual service the fuel filter was changed and showed there was no water present. Anyway I didn't get the sensor sorted and now 15,000 miles later the icon depicting water droplets over a petrol tank is still illuminated. The cost I've been quoted to replace the sensor is £277. Any suggestions for a cheaper solution?
