Car been odd today. Acting like turbo fault ( poor acceleration/stalling at low revs) then back to full turbo then no turbo.
Once home, all normal in dashboard. Switch off, then as I walk away I hear fan type noise coming from engine bay. Continuous. Open bonnet to confirm not radiator fan. Go into house. Pee.
Back out and still fan noise.


Restart engine. Check temps etc.
Stop engine. Noise now stopped after approx one minute.
Possible turbo " spinning down" due to high temp?

Unlikely, the turbo will spool down very quickly with the engine off. Heater blower fan?

Heater blower. Possibly but engine not hot.

Are there not two fans on the radiator?

You say "not radiator fan"

Clear the errors and see which ones come back.

Just happened again. Yes one radiator fan ran for 5 minutes after stopping.
Coolant, in top up not hot.

Pretty sure it's a engine temperature sensor fault.

Could be coolant sensor stuck on hot when engine is cold.

I think the sensor is u/s. CPU detects insufficient signal so elects for safe mode. Restricts power and assumes overheating

Damn. New temperature sensor was due to arrive today but...

I've got to drive 100 miles every day next week.

Will lack of functioning engine temperature sensor mean the engine gets to hot?

morew likely it will have the opposite effect and run more fuel and less timing to be sure it doesnt damage itself.

Replaced engine temperature sensor. Full power back and dash board temperature reading now working.
Thanks so for help/suggestions etc
