Water in diesel fuel - orange warning

Hi

I've had this warning light come on 2 weeks ago. I've taken car (2016 HRV diesel) to my local garage (not a dealership) and they "renewed the fuel filter" .

I've had one fairly long drive since then and no issues , however yesterday the warning came back on, and has stayed on now.

From what I've read the fuel pump needs draining of water and reset. I don't think my garage did this at all :-( .

Anyhow can't get to a local Honda approved garage until next week, but I have a 60+ miles journey to make on Wed and Sat.

Do you think it will be ok to do that and get it sorted afterwards?

Many thanks
