Hello,
Here's a piece of advice based on my experience, for the benefit of the reader:
"On our 3 1/2-year-old Ibiza, both mirrors (manual adjustment) would no longer fold in, despite our best efforts."
At first, I was even unsure if it would ever be possible, but a question in the Ibiza forum was clearly answered with "yes."
So, I fiddled with it a few times, jiggled it around, and then it started working again -> *creak, scratch...*
Beneath the removed mirror cover, I saw "beautifully" corroded aluminum, which had been damaged by salt and water, and which formed the hinge.
I first oiled everything and swung it back and forth about 20 times. Now it's working "like new" again.
If the oil has seeped everywhere in a few days, apply another layer of grease spray on top for long-term protection.
My Polo, of course, received two applications of silicone spray to the mirror hinges, as its mirrors are still relatively easy to move.
I would like to share the following as a preventative tip.
If our Ibi had made contact with an enemy while holding a broken mirror, it would certainly have torn everything apart as if they were completely immobile.
