oryx3dr,what has happened to your mirror glass?
Is this another potential issue i’ll have to keep an eye on??
I believe this issue has been discussed on several VW Golf forums over the years.
The adhesive backing on the door mirror glass can fail over time, resulting in the glass becoming detached from the backing plate in the mirror housing. If you’re unlucky and don’t spot it, the mirror can fall out of the housing and hit the side of the car when you’re driving. Seems that it’s more likely to happen if owners leave the mirror adjustment control permanently in the ‘heating’ position, as the heating effect appears to either weaken or dry out the adhesive backing over time.
Something to keep an eye on; if the mirror glass feels loose when washing the car or if the image in the mirror vibrates slightly while driving, it maybe a sign the adhesive backing is about to fail.
