Since I bought my Mondeo MKIII, 2001, I have occasionaly heard some strange noise coming from the engine compartment. This has been coming and going in periods, and have never been constantly present.
Have a look at this video for an example (link).
I know that the sound is not coming from the A/C compressor, alternator or water pump (i have removed the corresponding drive belts and the sound is still there.
It is very hard to localize it. It kind of sounds like it's coming from the front of the engine somewhere, but the exact location is very hard to find. Does anyone have any experience with this? It does not only annoy me alot, but I'm worried that ther might me a more or less serious problem/fault causing this.
The car has a maileage of ~21.000 miles (34000km), but is in very good condition. It has always been well maintained, both by the last owner, and me since I bought it (at 17.000miles / 27000km).
(I'm terribly sorry for the vertical video. I was more focused on getting the audio than very good video).
