Okay I have encountered my first potential issues in nearly 3 years of ownership, not bad eh.
Here is the problem.
The car is driven 10 miles from home to work with outside ambient temps ranging from 10-16 degrees. I leave work and sit in stop start traffic for 10 mins. My rad fans will kick in at 90/91 degrees as can be shown by the below OBD iPhone App.
The fans cool the water temps down to 85 degrees when they then shut off.
Start stop traffic again a little later in my journey and the fans kick in as necessary at 90/91 degrees. Temps reduce back to 85 and the fans shut off.
Now on the 3rd time the temps rise to 90/91 the fans activate but never turn off. From watching my coolant temps they never reduce down below 88 degrees, even when driving at say 30-40mph over say 1/4 of a mile.
So! Has anyone experienced such a strange problem or have any ideas of the root cause?
There could be a number of options from Sensors, Stats, Low coolant (which the level is fine) etc?
Anyone?
