After getting back my GTI I had loaned out for a while, it had a new strange sound, which is most noticeable at low revs, when there is not much other noise. Seems to have a louder resonance at some frequencies. I don't notice it so much listing under the hood.
It has a bit if a whine like a toothed belt or noisy electric motor armature.
Here's a recording from the interior passenger foot well (might be louder on that side) , during a slow drive through a parking lot.
Any clues as to what I should examine would be appreciated.
My car has 35000 miles.
My car has a manual transmission.
