 Have you checked the operation of your cooling fans? Just start the engine and dis' the grey temperature sensor in the top of the hose from the coolant output tank; the CANbus fires up both fans after a few seconds. When replacing the connector, wait a few seconds and observe the "spin-down" overrun behaviour -- they should both slow to a stop more-or-less together.

Both mine and Colin's had corrosion problems whereby one of the fans was partially-seized and the other was squeaking.

Bumper off, take off the plastic slam-panel cover, remove the sticky patch over the fans' retaining nuts (M5, l/h thread) and remove the impellers.

I've removed the motor units and Ferrosol-sprayed ours, but I think such maintenance is merely a stay of execution, as one of mine still has a degree of bearing-grumble.

The cooling fans probably get zero maintenance and, it seems, it's taken for granted that they'll fire up when required....

 I already had mine replaced a few years ago, it was corrosion so one of the fans had seized. The car didn't overheat as I don't do much city driving nowadays, but it's something worth checking every now and then.

Also, there was no faults in Lexia whatsoever.
