Default Help strange noise from my engine after switching off

Hello Can anyone help me i own a freelander TD4 thats great however at times, [intermittently] strange sounds come from the engine!!. This is usually once i have switched off the engine, there is a high pitched almost electrical sound mainly from the left side. After 10 - 20 seconds it stops suddenly, this happens mainly after short journeys on cold days, however sometimes it makes a different noise that is alot louder like a low engine noise again once the engine is off and it will stop abruptly. As its only intermittent its difficult for a garage to hear the sounds, can anyone help on what can be the matter with my car as i'm beginning to loose confidence with it. Thanks

On the left Hand side just behind the bumper is a Diesel heater just behind the bumper, it has an exhaust that comes out just underneith When you hear the noise check if hot air is coming out of it. i think it is there to give hot air instantly from the heaters when the air con is on and turned to hot. I noticed the same thing the other day whilst servicing a friends freelander!

Thumbs up Re: Help strange noise from my engine after switching off

Gemma,i had the same "problem" on my recently purchased TD4 and thought it was a fault.However it is only the FBH (fuel burning heater)located under front bumper at lower left side.It burns diesel fuel to speed warm up of engine and heat water for warm air for interior heater.It comes on automatically apparently if temperature 5 degrees or below ,after the engine has been running for 30 seconds and providing temperature of the heater case itself is below 65 degrees.When running you can also hear a clicking noise from behind panel behind right side rear passenger seat,this is the electric pump supplying the FBH.The heater runs for about 20 seconds after you switch off engine depending on engine temp (ie,if a short run).The noise will sound like an electric fan (like the engine cooling fan in fact).Unfortunately the owners manual does not seem to explain all this! I found the above answer on the net.

Have a look on Ebay for the badges (Land Rover and Freelander ones are both on there). Just type in "Land Rover Badge" and you should find what you're looking for, cheers, Mark

I wish my FBH had a dashboard switch so I could switch it off, tremendous waste of fuel on short journeys.

I have had a look at the circuit for the FBH and if you want to fit a dashboard switch to stop the FBH from starting this is how its done: locate the air temp sensor and connector, (behind r/h/s of front bumper) the connector to the sensor is co714, pin 1 (brown/yellow) is a feed signal from the engine control module (ECM) and pin 2 (slate/green) is the signal feed to the FBH, the temperature sensor is a normally open switch and closes when temperature drops to 5c when it closes the feed from the ECM flows through the switch to the FBH . So you can cut the wire (slate/green) going to pin 2 somewhere in the loom, extend both ends of the wire to the dashboard and fit a switch, as the feed is only a signal and not the power feed you can fit a low current switch, no need for a relay or a high current switch. Hope this helps.
