Buzzing noise.

[Simon Webb]

My, new to me, 2008 XK 4.2 has a buzzing noise coming from the dash when I switch it off. It seems to carry on indefinitely. Any ideas would be welcome please.

I get this on my 2009 (2010) model 5.0. Seems something remains powered up when the ignition is off.

It is the aspirator fan behind the dash that is running and making the buzzing sound.

Try squirting some compressed air through the small grill in front of the indicator stalk.

Thanks for the suggestion, Jimbov8, I tried this repeatedly, but unfortunately it did not solve the issue. It continues to buzz.

Hi Simon,

Your only recourse is to replace it. To do so you will need to remove the bottom half of the dash to access the connector. You will also need to remove the dash surround and the securing bolt that holds it in place.

The photo shows the sensor, the fan is behind that. You can actually remove the whole thing from the front though you will only get around 6 inches from the housing. You may then be able to blow air back through the fan.

If that doesn’t cure it then replace it. I think they are available for around £40.

This picture shows how far it comes out of the dash.

Thanks very much Jim.
