My partners Captur suddenly displayed an engine fault message and don’t drive.

She has noticed the cooling fan continuing to operate for a long time after parking up .

The coolant level is fine and no drips on the garage floor.

The warning sign cleared on re start

Calling Start in the morning for the car to be recovered to the local garage .

Any ideas please

Possibly an engine coolant temp sensor faulty or thermostat issue.

There has been coolant loss and there is a leak coming from the nearside lower engine region.

That could well be thermostat. It sits over gearbox area .

Now you mention that Doc there is lots of evidence of the thermostat housing cracking and leaking under pressures.

The use of plastics in this area is a concern but when the engine is used if the MB A class they use a different part which may be less susceptible to cracking .

Our initial diagnosis of a thermostat housing cracking was proved right.

With this common fault I would imagine there are lots of aftermarket pattern parts available . Will find out soon
