Strange overheating issue (2015 Vanquish)

[GG33]

Went out for a run this morning, stopped at agreed meeting point, fans came on + High engine temp warning light. Limped in to service area, checked coolant levels , levels good, no sign of coolant loss. Ign off, fans kept running. Called recovery truck. ! hr later, still same warning light and gauge off the scale. Engine didnt feel too hot and showed no signs of actual overheating.

Arrived home and unloaded car, temp gauge now normal. Took car for a good drive, nothing abnormal noted, all seems fine now. Fans not cutting in now.
Not sure what to do as we are due to be having a weekend away next week? (Car is still under warranty)

Any suggestions?

Cheers

If it was a stuck thermostat, it would deffo overheat, I thought faulty temp sensor, but puzzled as to how it has fixed itself? Just been out for another fairly good drive and no sign of any problem.... Confused..

Called the Main dealer this morning. They have never heard of a Vanquish overheating. Turns out we are all convinced it didn't actually overheat but was an electrical gremlin. They assure me that they can only diagnose the problem if/when it reappears (no code will be stored). I stated clearly that I had alerted them to the issue in case anything more serious came up whilst we are away in it this weekend. They assured me that was fine....

Just out of curiosity, I looked for a replacement sensor, only to discover that they cost £183 including Aston Martin tax, whereas a similar sensor for any normal vehicle can be purchased for about £11.99. :-O I'm sure it must be common to some other engine?

As a follow up, I have not had the issue since that one time. Sensor not replaced.

Be interested to hear results on the other posts.

Next question, does anyone have a video they can share or direct me to on how to change the oil on a 2015 vanquish? It will be due in about 6 months and this I will do myself. Thank you All, Bill

Filter removal is a bit tricky, see here. https://www.youtube.com/watch?v=QLf2zfBQO6U and here https://www.youtube.com/watch?v=9B_wPyuldsc
