ŠKODA Octavia A5 rear view mirrors: selection, replacement and typical problems

ŠKODA Octavia A5 (body 1Z3/1Z5, 2004–2013) is one of the most popular models of the Czech brand on the secondary market. The rear-view mirrors in this car, despite their simple design, often become a source of problems: from simple glass breaking to failure of electronics in heated and electrically driven versions. In this article, we’ll look at how to choose the right replacement, dismantle old mirrors and install new ones, and also look at typical faults and how to fix them.

Feature Octavia A5 — the presence of three types of mirrors: basic (without electronics), with manual adjustment and electric drive, as well as heated versions with turn signals. When choosing a replacement, it is critical to consider Vehicle VIN code and equipment, since fasteners and connectors may differ even within the same generation. For example, mirrors for the restyled version (FL, 2009–2013) are not always compatible with pre-restyle (pre-FL, 2004–2008).

Types of rear view mirrors Octavia A5: how to determine your version

Before purchasing a replacement, you must accurately identify the type of mirror installed on your vehicle. Not only compatibility, but also the complexity of installation depends on this. Total exists 4 main options:

• 🔹 Basic mirrors — without electronics, manual adjustment. Installed on basic configurations Octavia A5 (for example, Ambition or Classic). Article: 1Z3 857 501/502 (left/right).
• 🔌 Electrically driven — Adjustment with buttons on the driver's door. Articles: 1Z3 857 507/508 (without heating) or 1Z3 857 515/516 (heated).
• 💡 With turn signals - integrated LEDs. Articles: 1Z3 857 521/522 (for facelift).
• 🔥 Heated and auto-folding - premium versions (Elegance, Laurin & Klement). Articles: 1Z3 857 530/531.

To determine your version, check:

1. The presence of adjustment buttons on the driver's door (if available, electric mirrors).
2. Wires in the door: if the connectors are visible when removing the trim, it is a mirror with electronics.
3. Marking on the back of the case (usually applied with paint or a sticker).

Important! Mirrors with turn signals require additional verification of compatibility with the light control unit (BCM). On pre-facelift versions (pre-FL) may require flashing.

Articles and prices: original vs analogues

Original rear view mirrors for Octavia A5 are produced under the brand ŠKODA (items start with 1Z3) or VW (similar parts for Golf V, Jetta, Touran). Average prices for new original parts (2026):

Mirror type	Article (left/right)	Price, rubles (original)	Analogs (brand)
Basic (without electronics)	1Z3 857 501 / 502	4 500 – 6 000	Hella, Bosch, Febi
With electric drive (without heating)	1Z3 857 507 / 508	8 000 – 12 000	Valeo, Magna
Heated and electric.	1Z3 857 515 / 516	12 000 – 18 000	Sidex, Meyle
With turn signals	1Z3 857 521 / 522	15 000 – 22 000	Depo, TYC

Analogues cost 30–50% cheaper, but quality varies. For example, mirrors Hella or Valeo practically not inferior to the original, while budget brands (Depo, TYC) may have problems with the tightness or reliability of the electric drive. When purchasing an analogue, be sure to check:

• 📏 Case dimensions (original: 180×120 mm).
• 🔌 Connector type (on Octavia A5 3- and 6-pin options are used).
• 🔍 Presence of holes for mounting (distance between bolts - 50 mm).

Step-by-step instructions for removing the rear view mirror

Removing the mirror Octavia A5 does not require special tools, but it is important to follow the algorithm so as not to damage the door trim or electrical wiring. You will need:

• 🔧 Flathead screwdriver or plastic puller.
• 🔩 10 mm socket wrench (for mounting bolts).
• 🧲 Magnet or tweezers (so as not to lose small parts).

Procedure:

1. Open the door and remove the inner trim:

   1. Use a screwdriver to pry off the plastic plug near the door handle.
   2. Unscrew the two bolts under the plug (T20 Torx).
   3. Gently pull the trim towards you, starting from the bottom corner.

2. Disconnect the power connector (if the mirror has electronics). To do this, press the latch and pull it down.
3. Unscrew the three mirror mounting bolts (located under the decorative trim).
4. Remove the mirror by pulling it towards you. Be careful - some versions have a spring washer installed under the housing.

Critical point: on heated versions, the connector can be glued with sealant. Do not pull it by force - heat it with a hairdryer (temperature no higher than 60°C) to avoid damaging the wires.

⚠️ Attention: On vehicles with the system Keyless Entry (keyless entry) an antenna can be installed in the door trim. When removing the casing, do not pull the wires - this will lead to broken contacts!

Installing a new mirror: nuances and common mistakes

Installing a new mirror is done in reverse, but there are a few key points that are often missed:

• 🔌 Checking polarity: if you connect the connector incorrectly, the fuse will blow F37 (10A) per block SB22 (under the steering wheel). The connector is usually marked: +12V, GND, HEAT (for heating).
• 🔧 Bolt torque: 8–10 Nm. Over-stretching will lead to deformation of the case or cracks in the plastic.
• 🧴 Sealing: For heated mirrors, apply a thin layer of silicone sealant around the perimeter of the housing to prevent moisture penetration.

After installation, be sure to:

1. Check the operation of the electric drive (if equipped) in both directions.
2. Activate the heating (button on the panel or automatically when the rear window heating is turned on).
3. Make sure the turn signals flash in sync with the headlights.

What should I do if the mirror is not adjustable after installation?

1. Check fuse F37 (10A) in block SB22.

2. Inspect the connector for oxidation or broken wires (especially green and black).

3. If the motor hums, but the mirror does not move, lubricate the adjustment mechanism with silicone grease (for example, Liqui Moly Silicon-Fett).

⚠️ Attention: On restyled versions (FL) after replacing the mirror with turn signal indicators, it may be necessary to reset errors in the unit BCM via a diagnostic scanner (for example, VCDS or OBDeleven). Otherwise, the indicators will flash in emergency mode.

Typical faults and repair methods

Rear view mirrors Octavia A5 are subject to several characteristic problems. Let's look at their reasons and solutions:

Malfunction	Reason	Solution
The mirror is not adjustable	Motor burned out, wire broken, contacts oxidized	Replace the motor (part number 1Z3 857 601), clean the connector
Heating does not work	Burnt out heating element, open circuit, blown fuse F42 (15A)	Test the circuit with a multimeter, replace the element (part number 1Z3 955 701)
Cracks in glass	Mechanical damage, temperature difference	Replacing glass (item number 1Z3 857 611) or the entire mirror
Turn signal lights do not flash	LED burnt out, wire break, error in BCM	Replace the LED module (part number 1Z3 949 101), reset errors

If the power mirror “buzzes” but does not move, the problem is most often gears of the reducer. For repair:

1. Remove the mirror and disassemble the housing (carefully prying up the latches with a flat-head screwdriver).
2. Remove the motor and inspect the plastic gears for wear.
3. Lubricate the mechanism silicone grease or replace the gears (set item no. 1Z3 857 602).

Preventative advice: Once a year, clean the adjustment mechanism from dirt and lubricate it. This will extend the life of the motor and prevent jamming.

How to Adjust Your Mirrors for Maximum Visibility

Correctly adjusting the rear view mirrors Octavia A5 reduces the number of “dead spots” and improves visibility, especially when reversing. Follow this algorithm:

1. Left mirror:
   • Tilt your head towards the window and adjust the mirror so that you can see the rear wing of the car.
   • Return to normal position - the wing should occupy no more than 1/4 of the mirror area.
2. Right mirror:
   • Lean towards the center console and adjust the mirror so that you can see the edge of the rear bumper.
   • In the normal position, part of the rear window should be visible in the mirror.

To check visibility:

• 🚗 When driving on a straight road, there should be no “blind” spots in the mirrors where other cars may be hiding.
• 🚦 When parking in reverse, the wheel should be reflected in the right mirror (to control the distance to the curb).

If the electric mirrors “go astray” after a trip, the problem may be:

• 🔋 Discharged battery (voltage below 11.8V leads to position memory failure).
• 🔧 Loose motor mounts (you need to tighten the bolts or replace the spring washers).

Frequently Asked Questions

Is it possible to install heated mirrors instead of standard ones?

Yes, but you will need:

1. Route the wiring from the fuse box (F42, 15A) to the door.
2. Install the activation button of the heating (can be integrated into the control panel of the rear window heating).
3. Connect the connector to the mirror according to the scheme (contacts) +12V and HEAT).

Without connection to BCM The heating will only work in manual mode.

Why did the mirrors stop working when they replaced the mirrors?

Most likely reasons:

• Incorrect connector connection (contacts are mixed up L and R for left/right mirror).
• Error in block BCM (requires diagnostic reset).
• The LED in the repeater module burned out (check with a multimeter in vertebrae mode).

On pre-facelift versions (pre-FL) the light control unit may need to be firmwareed.

How to remove the glass mirror without damaging the body?

Procedure:

1. Heat the mirror with a hair dryer (50–60°C) for 2-3 minutes to soften the glue.
2. Tap the glass with a plastic blade from an angle where there is no heating element.
3. Carefully separate the glass by pulling on yourself (do not make an effort if you feel resistance!).

To install new glass, use 3M double sided tape or specialized glue (e.g., Loctite 406).

What safety locks are responsible for mirrors on the Octavia A5?

List of fuses in the block SB22 (driving):

• F37 (10A) is the electric actuator of mirrors.
• F42 (15A) Heating of mirrors and rear windows.
• F58 (5A) – control of repeaters of turns (on restyled versions).

If fuses often burn out, check the circuit for a short circuit (especially at the place of passage of the wiring through the door corrugated).
