Strange electric motor noise when parked up

This has happened a couple of times on the Freelander 1.8 when I have parked it at night, side lights on, when walking away from the car it sounds like an electric motor noise as if something was being adjusted a bit, no idea what it is though and had forgotten about it till now!

Any ideas

Is it a clickly click clack clack clack noise?

if so its the IACV stepper motor

Basically when the throttle body is closed the engine breaths through a tiny pipe

This must be regulated to allow it to idle a the right speed under varying conditions like cold starts or when the engine gets old etc

This just resets itself when the iginitions turned off, nothing to worry about

Fuel Burning Heater perhaps??

I have what appears to be an electric motor noise, 53 TD4, when I turn the engine off, but leave the ignition on. I researched on here for the location of the FBH exhaust, from the three pics I have seen, it appears to exit on the passenger side, to the rear of the front wheel station. But I can't see an exhaust there, so who knows what it is..? I don't have any problems with it at the minute so I'm not bothered!

Would it be an ewp?

Just checked, I have the hole in th chassis for the exhaust, but no exhaust!

Lift the bonnet and have listern. I once had a faulty head light level motor, that ran constantly only when the head lights were powered. Also there's a fan that runs in the L shaped computer box, if the computers too hot, to cool it.

Now that's a possibility - I will check it out, thanks

TD4 noise when turning off?

if you have one the exhaust exit is in front of the left front wheel....

I had a similar issue that Hippo describes on my Disco. It was a ****ty contact that carried on trying to adjust the level.

You were right the noise is from the o/s headlight, it doesn't do it all the time though, probably just easier to disconnect the motor.

When it happened to mine, I swapped over the level motors to prove it wasn't a fault in the wiring, as opposed to the motor. Car was new to me at the time. Motor sort of turns to release, but it still holds on via a peg. Peg slides out sideways somehow to release it all.
