Is it bonnet off time ? I've looked on Alfaworks but can't find anything.
This..... A few good blows may help release the foriegn material.
I'll give it a try (perhaps with compressed air, @tibby , don't get excited).Have you tried blowing back into the vents to clear them of any obstructions? A few good blows may help release the foriegn material.
It'll probably make a louder noise!Could you try an inspection camera?
I now what you mean.@4Canada
I really hope you didn't have a tenant nesting under the hood over winter and s/he pulled in a bunch of bits to nest in.
Not long ago I opened the hood on our Bolt EV to add some washer fluid only to find a tidily built nest sitting on top of the motor/power-controller - and that car was used all winter! Although in that case it kind of makes sense because of the battery heater running so much.
I know it's unlikely, but I would prob still pull the hood just for peace of mind to be sure there's not more stuff waiting in there somewhere.
I have the same problem. It started suddenly without much progression (ie became loud like yours all of a sudden). My mechanic was doing some other routine maintenance so I asked him to take a look and he said the fan needs replacing. I'll report back when I go and see him and the old part to see if a new part was actually necessary.I now what you mean.
Pretty certain there won’t be anything obvious, as I had the bolt tightening done this spring (track car) so they would have had the hood off and seen it.
But you are right that this does not preclude a nest in the ductwork. I’ve got a pretty sensitive nose to that sort of thing and have not noticed any odd odours.
Still, will look into that this weekend.
