    Strange Noise On Shut Down

    With my TD5 after I turn it off I have a buzzing short and sharp sound, like two sort bursts of noise. Does not do it every time I turn the motor off only sometimes which is the strange part.

    It's not the central oil filter whirring down it sounds competely different to this.

    Any ideas what to look for?

    Could it be electrical?
    Doesn't sound good what ever it is.

    That's what I am thinking has to be electrical due to the motor being shut off, but no idea where to even start looking.

    Try starting with the wires around the steering column. Might be a loose connection that gets upset when you turn the key. After that good luck and you might need 2 people. One to shut down while the other moves around the vehicle trying to find where it is coming from.

    Only other thing I forgot to mention that's different is the noise has started since I got some driving lights fitted to the front. I not sure if it could be related.

    That could do it. Check the switch connections and where you tapped into the power. I would say it is the cause.

    manually turn the sound system off before shutting down the engine and see what happens... it might be transient voltages buzzing the amps on the 12v hot supply to the head unit.

    but thats a WAG.

    Thanks for the replies. Trouble is I have been out in the garage turned the car on and off four times and you would not believe it can't find a trace of the sound. As said it only does it every so often and it will be most likely in the morning when I am pulling up at work and don't have time to fiddle about. Murphys Law.
