    Prices on bill are in Euros, net - 20% VAT added at bottom - so pipe was approx £1100
    Top half of bill is for annual service, bottom half for overheat

    the str has a higher engine temp before the thermostat kicks in and higher overall normal running temp. It is quoted in JTIS what it actually is

    The cooling fans were coming on during driving, and for 20 Minutes after garaging - and the ambient temp was only 20 degrees Celsius. Never heard fans before.

    That's how I knew something was wrong!

    The temp gauge was still showing "normal" 50%! (even when engine checker said 110 degrees C

    yes, that temp gauge is as about as inaccurate as inaccurate can be, I never rely on that, use the diagnostics mode on the stalk to see the correct coolant temp

    But even that stalk coolant temperature depends on the accuracy of the coolant sensor, does it not?
    And if the sensor is bad, one can be misled?

    At least you'd know from it what the car (PCM) is being told by the sensor - whereas the dash gauge is almost useless.

    Agreed! But if sensor said 110 degrees C and fans were running and my engine tester said 110 degrees, I knew ai could not trust the gauge!
    Without the fans coming on I would not have known I had a big problem.

    You'd know if you'd have read the temperature and gone "wow that's too hot"... (or asked here)

    Nothing seemed "too hot". Just that the fans stayed on after getting back to the garage.
    I am no expert, but I do have a Gendan Engine Checker, which I used to check temperature.
    It showed no faults. But it showed the temp rising to 110 degrees C - before I switched off engine for safety.
    The radiator temp, checked by an infrared thermometer showed only ambient 21 degrees C.
    So thermostat was not opening.
    So either thermostat faulty, or temp sensor faulty.

    car is 15 years old, serviced by a Jag annually, only 50,000 miles.
    Due to high indicated temp, could not safely drive car far, and since no proper independent Jag garage near, I decided to take car to local Jag dealer.

    Big bill as you can see above

    My original post here asked about price of replacement parts - but I had asked other Jag forum for advice on the overheat problem.
