Overheating and `'Blind Spot not available fault

So...the traffic was unusually bad on the crawl home yesterday; about 30mins in to the journey suddenly an "overheating engine" warning light flashed up. <div><br><div>And as I watched the engine temp readout started to quickly climb. So I switched on the heaters full blast and kept my fingers crossed it didn't break down as I was in 3 lanes of stop start traffic and would have been possibly the most unpopular man in the city. Weirdly 5 mins later the temp gauge dropped back to normal like a stone and stayed normal the rest of the way home. At the time I wondered whether it had been breathing the hot exhaust gases from the Transit in front but thought that was more in F1 cars than a Jag following a van at 0-5mph</div><div> <div>I had to get some petrol and on restarting the car another warning light came up "Blind spot not available" and the little orange LED on the passenger wing mirror wasn't working. Engine temps remained totally normal. The fault still shows up even after being left alone overnight.</div><div>Sounds electrical to me...anyone got any clues?</div><div><br></div><div>Off to the dealers on Monday. Nothing untoward I can spot in the engine bay, nothing smells burnt, the other systems that have the same fuse are all fine so a little stumped!</div></div></div>

Certainly sounds electrical/software/sensor related.<br><br>Not had anything remotely similar happen on mine..yet...so nothing I can help you with i'm sorry to say.<br><br>Will be interesting to know more after your visit to the garage. Good luck.<br>

<div> </div><div>I'd be surprised if the two symptoms are connected...</div><div>Sounds like a connection issue between either the temperature sensor and the radiator fan and/or dodgy temperature sender, giving a false dash-board reading.</div><div> </div><div>I have been at events where we have thrashed F-Types to within an inch of their death and had them lined up ticking over in 37 deg C ambient temperatures...never heard of them overheating. In actual fact, the cooling system on the V8's is remarkably efficient, and only rarely should/will you hear the fan cut in.</div><div>The BSM could be a connection issue between the mirror and the door harness.</div><div> </div><div>My first port of call...Charge the battery overnight. Disconnect the battery negative and leave off and go have a cup of tea. Reconnect and check all the systems...you will need to reset the window up/dn limits, but at least it would have cleared the cars' brain.</div><div> </div><div>Good luck with the dealer...!</div>
 
Tel....Just out of interest, what is the procedure for resetting the window up/down limits and why is that the only thing we would need to configure after a re-boot ?<br>I'm interested to learn a bit more about these kind of things.<br>

with how quickly the temp readout dropped back to normal and the otherwise faultess engine performance I did think it all sensor related...but stuck in traffic was wondering if the ECU would shut down the engine if a faulty sensor said it was overheating. I hope it's not an omen for a series of hard to fix electrical gremlins
 
Hi Megatron - what was the outcome in the end? <div><br></div><div>I had a very similar experience yesterday. After 2.5 hours driving (coming back from a service ironically), we were sat in slow moving traffic for 5-10 mins, then the windows misted over even though the AC was supposedly on, and the engine temp started to rise very quickly in pretty big jumps over a minute or so giving first the yellow then the red warning message.</div><div><br></div><div>Luckily just before the temp needle hit the red, the lights changed, and as soon as I started moving the temp dropped back to normal and the AC clearly kicked back in.</div>
 
Ah yes - should have updated the post with the outcome. So they had a look and it turns out it did indeed overheat and it wasn't a software glitch - faulty module/relay affecting the cooling fan. This module also caused the blind spot warning issue. They changed the faulty module and all was well; and I've had no issues since. I'm more watchful of the temperatures since though
 
Thanks for updating.<div><br></div><div>I wonder if the same module might have impacted the A/C on mine. I'll pass that along and see if it helps.</div>
 
Hello everyone, This is my first post (call for help!!!). Any advice on what to look for will be appreciated. I have an F-Type 2017 v6 with 29,650 miles. After replacing all 3 coolant pipes and the water pump, the car started to overheat. Those parts were changed due to the fracture of the upper coolant pipe. The mechanic tells me that it could be a temperature sensor or the fan. The system was pressurized again to see if there was a leak, but nothing leaked. What seems strange to me is that before the change, everything worked. Another symptom is that the AC doesn't get cold. I live in the Caribbean, so I think my fan should be extra cold. There are 2 types, standard and extra. But everywhere I read, says that the fan in this car rarely fails. The mechanic says that the fan never enter in high mode, resulting in overheating. The system was purged for a second time with no change of the situation. The mechanic changed a temperature sensor in the front, but nothing change. The fan only rise to 25% looking it with the diagnostic tool.


Thanks,
jc
