The VW Polo is a compact car based off of the VW Golf. In the North American market, it is classed as a subcompact. It actually uses many of the same parts as the Golf, including the side mirrors. While the Polo is a very small car, it can break its side mirrors too. This broken glass must be removed before a new glass mirror can be put in. Luckily, the glass is just held in by glue, so all it takes is some hard scraping.
Park the VW Polo in a well-lit garage or in your driveway during a bright day. Make sure to pull the emergency brake to keep the car from moving while you work on it.
Use a flathead screwdriver as a pry bar and slip the tip under the lip of the mirror glass. Pry the mirror off with gentle rocking motions along the edge of the glass. Don't worry if the glass shatters. Just work the individual pieces off.
Scrape the remaining glue off with a razor. Use short scraping motions to get off the big pieces. Once all the lumps are off, soak the tip of a towel in solvent and work it on the back plate of the mirror. This prepares the back plate for the glue that will hold the new mirror in place. The cleaner the backplate, the better the new glue will bond.
Do not perform this repair on the side of the road as you could be hit by traffic.
