How to choose the right new mirror for the Skoda Octavia A5

Before starting work, it is necessary to determine the type of the replaced node. The parts market offers a huge range, but not all of them will fit your car. The key factor is compatibility in electrical circuitry and type of attachment.

Original mirrors Skoda They provide perfect fit and durability, but their cost often scares away owners. Quality analogues from proven brands (for example, Kia or TYC) can be an excellent alternative, retaining functionality at a lower cost. The main thing is to pay attention to the body color code, since painting in the color of the car is sometimes required separately.

Make sure to check for the following features in your package: electric drive adjustments, heating glass, electric heating housing laying-up. If you install a mirror without heating instead of a regular one with heating, the cabin heating function may stop working correctly due to a chain break.

Pay special attention to the left and right mirrors - they are not interchangeable, as they have different glass curvatures (aspherical glass on the driver's side). Incorrect installation will result in picture distortion and poor visibility.

Tools and preparation for dismantling

You don't need a complex set of tools to make a successful replacement, but having specialized equipment will make the process much easier. The standard set includes a set of socket wrenches, screwdrivers and a plastic spatula for carefully prying out elements.

Also prepare flat screwdriver with rounded edges to avoid scratching the paint when removing the decorative cover. If you do not have experience working with plastic, it is better to use a specialized one. trim remover.

It is important to provide access to the mounting bolts, which are often hidden under plastic plugs in the wheel arch. To do this, you may need to unscrew the wheel or simply turn the steering wheel all the way in the direction opposite to the mirror being replaced. This will create the necessary clearance for work.

Before starting work, be sure to turn off negative battery terminal. This is critical to prevent a short circuit when disconnecting the mirror electrical connector, especially if you have a auto-folding.

Step-by-step instructions for removing an old mirror

The dismantling process begins with access to the mounting bolts. Open the door and, if necessary, remove the triangular plastic trim covering the mirror mechanism on the interior side. It is held on by plastic clips, so carefully pry it off with a spatula.

After removing the trim, you will see the bolts securing the body to the door. There are usually three of them. Unscrew them with the key Torx. Do not forget to first disconnect the electrical connector by pressing the latch so as not to damage the wires when pulling out the housing.

On the outside of the car, in the wheel arch area, you will find another bolt, which is often the main load-bearing element. Unscrew it, holding the mirror with your other hand so that it does not fall to the ground and break completely.

Gently pull the mirror housing towards you until it comes out of its seat. If the mirror does not budge, check whether you forgot to unscrew all the bolts. Do not use excessive force to avoid breaking the plastic clips or wiring.

After removing the old assembly, inspect the installation site for corrosion or paint damage. If necessary, clean the surface and apply an anti-corrosion agent before installing a new element.

Features of installing a new mirror and connecting

Installing a new mirror is performed in the reverse order. First, carefully insert the housing into the seat, lining up the bolt holes. Make sure the rubber seal fits snugly against the body to prevent moisture from getting inside the door.

Install the bolt in the wheel arch and tighten it with moderate force. Then fasten the bolts on the interior side. Do not over-tighten them, as the plastic may crack and the mirror glass may burst from stress.

Connect the electrical connector until you hear a characteristic click. Check that the latch works securely. If you are using an adapter to connect a non-standard mirror, make sure the wires are pinned out correctly.

Turn on the battery and check all functions: vertical and horizontal adjustment, heating and folding. If a function does not work, check the fuses and wiring.

It is important to check the tightness of the connection. If you notice traces of water on the glass or inside the door, the seal may have been installed incorrectly or may be damaged.

What should I do if the connector doesn't match?

If the connector of the new mirror is different from the standard one, do not try to change it by force. Buy a special adapter or contact an auto electrician to resolder the contacts, observing the color coding of the wires.
