Disassembling the Škoda Octavia A5 mirror: detailed guide with photos and videos

Rear view mirrors Škoda Octavia A5 (2004–2013) is one of the most vulnerable elements of the body. Over time, they lose precise adjustment, the glass cracks, and the electric drive stops working. Disassembling the mirror may be necessary to replace the glass, repair the mechanism, or install new functions (for example, heating or turn signals). In this article we will analyze the process of dismantling and disassembling step by step, pointing out key nuances, which are often missed in standard instructions, and we will give recommendations on the selection of spare parts.

Important: the design of the mirrors on Octavia A5 depends on the configuration. Models with electric drive and heated ones are more difficult to disassemble than mechanical ones. If your mirror is equipped turn signal (built into the housing), you will have to additionally disconnect the signal wiring. We took into account all the options and compiled universal instructions.

What tools are needed for disassembly?

Before starting work, prepare your tools. Without them, you risk damaging the plastic clips or door trim. Here minimum set:

• 🔧 10 mm socket wrench or socket - to unscrew the mirror fastener to the door.
• 🔨 Plastic puller or pick - to pry the door trim without scratches.
• ⚡ Phillips-head screwdriver (PH2) - for screws inside the mirror housing.
• 🔥 Hair dryer or hot air station — if you need to remove the glass glued to the mechanism.
• 🧲 Magnetic holder - so as not to lose small screws and washers.

For models with electric drive, you will additionally need multimeter (to check the circuits) and electrical tape for marking wires. If you plan to replace the glass, buy it in advance adhesive sealant for car glass (for example, 3M 08609 or equivalent).

Preparation: how not to damage the door during dismantling

The most common mistake during disassembly is damage to the door trim. On Octavia A5 it is attached to plastic pistons, which break when removed inaccurately. To avoid problems:

1. Lower the door glass all the way - this will give access to the lower trim clips.
2. Remove the door handle (it is secured with one screw under the decorative plug).
3. Carefully pry up the trim using a puller, starting from the bottom corner. The pistons usually fit tightly, so apply pressure evenly.

After removing the casing you will see technological hole to access the mirror mechanism. In some configurations it is covered with an additional plastic cover - you need to remove it by prying it off with a screwdriver.

Removing a mirror from a door: step-by-step instructions

Once the casing is removed, you can begin dismantling the mirror itself. Algorithm of actions:

1. Disconnect power connector (if the mirror is electric). It is usually located next to the fastener and is secured with a plastic latch.
2. Unscrew three 10 mm nutswho are holding a mirror. They are located on a metal plate on the inside of the door.
3. Remove the mirror from the guides. If it is tight, wiggle it slightly from side to side.

At this stage, many people encounter a problem: the mirror does not want to come off, despite the nuts being unscrewed. Reason - corrosion of the guides or deformation of the mounting plate. In this case, WD-40 or lightly tapping the base of the mirror with a rubber hammer will help.

What to do if the mirror is jammed?

If the mirror does not come off even after unscrewing the nuts, check:

1) Is the metal bracket on the door bent (often happens after an accident).

2) Are the guides rusty? Treat them with penetrating lubricant and wait 10–15 minutes.

3) Does the sealing gum get in the way - sometimes it sticks to the paint and blocks movement.

Disassembling the mirror housing: access to the mechanism

Once the mirror is removed from the door, it must be disassembled to get to the glass or adjustment mechanism. The design of the case depends on the configuration:

• 🔄 Mechanical mirrors They are easier to disassemble: just unscrew 2-3 screws on the back side and remove the back cover.
• ⚡ Electric mirrors have an additional block with motors. Here you will have to unsolder or disconnect the wiring connectors.
• 💡 Heated mirrors require special care - there are thin heating elements inside that are easily damaged.

To access the glass:

1. Remove the back cover of the case (it is usually held on by latches).
2. Unscrew the screws securing the adjustment mechanism.
3. If the glass is glued, heat it with a hairdryer (temperature no higher than 60°C, so as not to damage the plastic).
4. Use a plastic spatula to pry up the glass, starting from the top corner.

Typical faults and how to fix them

Here are the most common problems with mirrors Octavia A5 and ways to repair them:

Malfunction	Reason	Solution
The mirror is not adjustable	Worn mechanism gears or broken wiring	Replacing the mechanism (article number 1Z1 857 007/008) or soldering wires
The glass has cracked or fallen off	Impact or loss of adhesive properties of the sealant	Glass replacement (original 1Z1 857 501) with sizing
Heating does not work	The heating filament has burned out or the contacts have oxidized.	Checking with a multimeter and replacing the heating element
The mirror vibrates at speed	The mounting nuts are loose or the bracket is deformed	Tightening the fasteners or replacing the bracket

If the problem is with the electric drive, check the fuse first F37 (10A) in the block under the steering wheel. He is responsible for powering the mirrors. Also inspect the connectors for corrosion - on Octavia A5 Contacts often oxidize due to moisture ingress.

Replacing mirror glass: nuances and selection of spare parts

Glass is the most fragile part of a mirror. On Octavia A5 it could be:

• 🔍 Regular (flat) - article number 1Z1 857 501 (left) / 1Z1 857 502 (right).
• 🌑 Anti-glare - article number 1Z1 857 501 A (driver's side only).
• 🔥 Heated - article number 1Z1 857 501 C (has contacts for connection).

When purchasing, pay attention to marking: original glasses have logo Škoda and production date. Cheap analogues (for example, from Febi or Hella) may not fit correctly or may have a distorted reflection.

Replacement process:

1. Remove any remaining old glue from the mechanism (use solvent 646 or acetone).
2. Apply new sealant to the mechanism base thin layer (excess glue will lead to smudges).
3. Press the glass and secure it with masking tape for 2-3 hours.

⚠️ Attention: Do not use superglue or epoxy resin - they will turn yellow over time and spoil the appearance of the mirror. Only specialized automotive sealant!

Assembling and installing the mirror back

After repairing or replacing parts, reassemble the mirror in the reverse order. Here are the key points:

• 🔌 Check polarity when connecting connectors (on electric mirrors, mixed up wires will lead to a non-functioning drive).
• 🔩 Tighten the fastening nuts criss-crossto avoid skew.
• 🧼 Remove traces of sealant from the housing before it dries - then it will be more difficult to do.

After installing the mirror on the door:

1. Connect the battery and check the operation of the electric drive (if equipped).
2. Adjust the position of the glass so that you can see through it 20% rear wing and 80% of the road.
3. Make sure the turn signal (if equipped) flashes in sync with the main signals.

⚠️ Attention: If after assembly the mirror hums or is adjusted jerkily, it means that the gears of the mechanism are installed incorrectly. Take it apart again and check the alignment of the teeth.

FAQ: Frequently asked questions about disassembling mirrors Octavia A5

Is it possible to disassemble the mirror without removing the door trim?

Theoretically yes, but it is extremely inconvenient. Without removing the casing, you will not be able to properly unscrew the fastening nuts and risk damaging the wiring. It is better to spend 10 minutes dismantling the casing than to repair broken wires later.

What sealant is best to use for gluing glass?

Optimal options:

• 3M 08609 — professional adhesive for car glass, withstands temperature changes.
• Terostat 922 — elastic sealant, does not turn yellow over time.
• ABRO WS-904 - a budget analogue, but requires longer drying (up to 24 hours).

Do not use silicone sealants - they do not provide sufficient strength.

Why did the mirror become less reflective after replacing the glass?

Probable reasons:

• Glass installed crooked — check the angle of inclination.
• Used non-original glass with distorted optics.
• Got under glass air or dirt — disassemble and re-glue.

How to check the operation of the adjustment motors?

Connect the mirror to power and apply voltage 12V directly to the motor contacts (plus and minus alternately). If the motor does not rotate:

• Check brushes - they could be erased.
• Measure the winding resistance with a multimeter (should be 10–50 Ohm).
• Clear contacts from oxidation.

A faulty motor is easier to replace than to repair.

Where to buy spare parts for mirrors Octavia A5?

Original parts can be ordered by VIN code from official dealers Škoda. Alternative options:

• Exist.ru — a wide range of analogues (for example, Hella, Febi).
• Car disassembly - cheaper, but check the condition of the parts.
• AliExpress — Chinese glass and mechanisms (risky in quality).

For electric mirrors, take only the original or proven analogues (for example, Valeo 133538).
