got that message yesterday and this morning also, so I went and bought a liter of 50/50 coolant (blue), i'll add it once the engine cools after this morning's drive, however should I be worried about this message, i googled a bit and found another person with the same car and in that thread they were referring to head bolts and hydrolock possible issues, all scary stuff, i guess i should get worried if after adding the replacement coolant the message doesn't go away...

your thoughts are appreciated as always..

Keep an eye on it, I have the same thing with my car with the same engine in, could be a coolant leak which will probably be the water pump

so i added one liter of coolant yesterday and the message has not come back, hopefully it was just in need of a top up and that'll be the end of it, but i'll keep an eye out and report back if it changes, cheers
