Engine running too cool , so best change the coolant thermostat ... Have you not noticed the Temperature gauge not reading the usual Mid scale reading ?

If anyone does have a sequence of button presses that activates a "hidden menu" for water temperature, I would be more than happy to hear this.

However, there are a number of OBDII solutions available.

Either for pulling data into a smart phone or Garmin sat nav or, with their own display. Some examples below, I would be glad to hear of any feed back on the Scangauge or ideas or where to put the display.

Bluetooth dongle to connect to smartphone with app:

I've found that for the first couple of minutes from cold start most volvo engines are not producing their full power , I would think this is the protection you are wanting .. It only takes 2 or 3 minutes for the engine coolant to be hot enough ...

Some posts in this thread mention some hidden onboard computer (OBC) features?
Do any of these include the coolant temperature?

I don't want to have to fork out for a diagnostics kit when ever I come to change my coolant just so I can check it has bled properly and isn't overheating!
I'd also like to be able to check the coolant temp should I make a rest stop on a long journey (like the one I'm undertaking tomorrow)!

See my post#18 above . when there is something wrong , ie too cool or too hot you will know about it before it becomes a problem , Very rare to see these messages ,

On my old v70 TDI the gauge got to normal setting in 3 or 4 miles. I have used that example on my gaugeless xc70 and drive it gently for the first few miles.
Was always told never cane a cold engine as a youngster, while I accept engine technology has moved on the principle still remains to my way of thinking, warm it up before giving it the beans.

TorquePro app on an android phone with a Bluetooth ODB2 reader is a very cheap setup and easy way to monitor engine temps.

I would wait longer than 3 or 4 miles for a modern Diesel to reach normal running temp.

EGR valves and better efficiency means they take longer for temp to come up.

Out of curiosity I hooked up to Torque Pro this morning......at start up (from last night and it's still summer.......ish) the temp was 20 C, at 4 mile into my journey it reached 89 C at which point a little green light started to flash and then stop flashing. This kept on repeating so I assume that it indicates the stat is opening and closing.
Obviously when the cold weather arrives it would imagine the miles covered will increase.........I'll check again in the winter.......
