Top up coolant message (2019 Vantage)

[mx stu]

Afternoon,

Had a top up coolant message pop up on my 2019 Vantage earlier in the week and spoke with Grange Hatfield who said to top it up with 0.5L of water, which took it to an inch or so below the neck. However the message is still there. Looking through the forum I see a fair few issues with the sensor on the previous model but nothing really about the newer model. I've used it a couple of times (relatively short journeys) since the message has popped up and there have been no issues with engine temperature.

Anyone had similar issues?

I must say the biggest downside of ownership at the moment is the distance to the nearest main dealer and the lack of a decent (or any) independant in the local area (Cambridgeshire).

On the earlier model had the same issue, bought a new sensor for the coolant bottle, less than £20 and fit in 5 mins, easy job. Not sure about 2019 model, but maybe not too different ?

There is a secondary expansion tank for the Turbos (and the rear diff?) located under the engine cover with the plaque. It's likely low there.
The rear diffs on these have been known to leak. Look for dried white/pink coolant stains around rear Ediff area.

Yep Cambridgeshire is starved of either main dealers or indies. Such a shame

Thanks all for the suggestions, had someone look over it and nothing obvious so more tests required. Oh and also they've spotted a hydraulics leak.
