I sent my 2007 Golf Rabbit Mk5 for repairs after someone clipped and damaged the driver side/wing mirror beyond repair. When I got my car back after the mirror was replaced, I noticed something seemed off about its field of view.

After some inspection, I believe the problem is that objects in the driver's mirror now appear at the same distance as for the passenger mirror, whereas they should appear nearer. I'm pretty sure this is the situation, and yet I cannot think of any way the mechanics could have messed up this repair, since the driver mirror is usually just a flat surface (in contrast to the passenger mirror which usually has a curvature).

Can anyone shed light on what could have gone wrong here, or am I just imagining the problem?
