Common problem on the Renault Master - our van is based on it. The first thing to try is to open the drain on the fuel filter and drain off a good cupful of diesel. That may sort the water in fuel indication.
The other possibility is that, if your base vehicle is new enough to have an EGR valve, that may be sticking due to gunge build up. Our van has been in for service (just) with our local excellent Renault Trucks service dealer. They looked at it on their computer and said to ignore it, but do an "Italian tune up". That is, drive it for a good few miles (50+) at higher than normal revs. If it is EGR gunge, then that should clear it. It did, after a longish run.
Luckily, our service dealer is VERY good at fault diagnosis, and I have come to trust him when he says "no real problem to worry about". He could makes pots of money out of me, going through all sorts of diagnoses, but instead is quite honest.
PS - the dealer is Thompsons Commercials of Billingham - they have branches around the North-East. My only link with them is as a very satisfied customer.
No longer motorhoming due to illness, but always prepared to help by sharing any experience I may have.
