Low coolant level warning?

I've noticed that I get a 'Low Coolant level' warning on starting up, but this isn't borne out by a visual inspection of the reservoir which shows that it's fine.

Any ideas what may be causing this?

The float in the reservoir is faulty and needs replacing t'is a common problem

Many thanks. Nothing too serious and I can probably live with it!

Very common problem, most were changed under warranty in their early years.

ISTR that the replacements parts weren't that expensive so worth changing sooner rather than later even if out of any warranty.

do not just replace the sensor !!!! it is not the sensor thats faulty it is the floating magnet inside the coolant bottle thats the fault, full coolant bottle comes with sensor fitted and only costs around £17 genuine.

swapping easy just clamp hoses remove bottle , fit bottle unclamp hoses and top up! takes around 10mins.

I did try the sensor option first, the fault turns out to be the floating magnet absorbs coolant over time and this does not help it with its floating abilaty.

errr.. 10 minute job, I'm an hour in and still trying to figure out how to get the bottom hose off Big Cry - did you disconnect all the other hoses 1st to get access ???
Not a 10 minute job in my humble opinion... also had to disconnect hoses to diesel heater to get at that bottom hose on the tank..... life would be much easier with a workshop manual - any sign of one coming ? Question

I have looked at the photos taken while it was stripped and the grille and headlamp where removed , I am sorry for missing that out on the instructions Embarassed

thats why the second time i removed the bottle it didnt take long.

feel like Censored now !
