Im in Australia too.Hi Lee - I live in Australia, I'm having the same problem with my 2014 Jeep Diesel Overland. Based on other reports I've seen of this problem I had the coolant sensor changed 2 weeks ago (not the housing and thermocouple). That's really poked the bear, I have had 5 recurrences since then. Did the replacement of all those parts fix your problem. Cheers Terry
2014 Grand Cherokee, Overland diesel.
Has been a flawless car for +200,000kms.
The exact same lights, gauge failure and revving fan happened to me tonight.
Have you had any luck repairing the problem?
