i leave this question to someone on here to answer there are a great bunch they will know what is wrong .

The book says
Air trapped in the system
Fluid level too low
Fluid mixture too weak or strong
Circulation pump not working
Sensor defective
12v supply not stable

Cheers , i have a feeling its air and mixture strength , going to book my service early and get heating done at same time.

Previous owner just said they topped up when required but i am unsure if they used neat fluid.

Thanks.

I had a similar message recently. My battery had gone flat overnight. . After turning off the 12volt supply and charging the battery the message disappeared (after resetting the heating control to reset). . Two weeks later my battery overheated (while we were away in the caravan on electric hookup) . So the battery was on it's last legs.
