Hello again Rod -

Im sorry I could not get back to you earlier -

Ok - apart from the possibilities of a small coolant leak somewhere on the system - I strongly suspect you have a water pump leaking. With that its very hard to see espeically when its a small leak. In any event, the way forward Rod is to have a local type garage do whats called a "pressure test" on the system. This manually raises the pressure on the system to as if you were driving - which is when it loses, and you cannot see it. That way - the leak will be seen wherever it is... and so then can be addressed.

As for the management fault light - this wont have anything to do with the above- you need to have a plug in fault code read done Rod to see what fault codes are stored. There will be fault codes as the light is coming on but the reasons for that could be any one of a hundred...literally.. So you have to have that done - then once you have the fault code- that directs the tech / user to the cause.. and that then can be seen to. You are losing power when the light comes on either because of the actual fault itself, or, because the ecu is putting the engine into Limp Mode.. so you have to have that checked as above - there is no other way Rod on that....

Just going back to the coolant loss - IF no leaks are found, then its possible you have a head / head gasket issue - a slight leak - not water going into the oil - but going into the combustion chamber - that way, it disappears out the exhaust without you even knowing. If this is happening, it could couple up with the cause of the EML coming on - If that is suspected, the garage will do a CO test on the system, and / or a dye test to confirm the issue - then go from there as found...

Without having the equipment yourself, Im afraid you can do very little at home / diy... so thats the way forward to get this sorted for you now Rod..

Im very pleased to have helped you -let me know if you need anything more -
