Left side mirror on Skoda Octavia A5 (2004–2013) is a safety critical element that often suffers from mechanical failure, corrosion, or electrical failure. Unlike the right mirror, the left one is subject to greater loads: it is more often touched when parking, it freezes more in winter due to the oncoming air flow, and in models with electrically adjustable and heated contacts fail more often. Owners Octavia A5 are faced with problems ranging from simple broken glass to breakdown of the folding mechanism - and in each case a different approach to repair is required.

In this article we will analyze all aspects of working with the left mirror: from the selection of original and analog spare parts to step-by-step replacement, taking into account the nuances of electrical wiring. Let us separately dwell on typical installation errors that lead to a short circuit or non-functioning heating. If you are looking for article numbers, connection diagrams or adjustment tips, here you will find verified information without β€œfluff” and general phrases.

Left mirror design Octavia A5: what's inside?

Left mirror on Skoda Octavia A5 (body 1Z3) is structurally different from the right one not only in shape, but also in the internal β€œfilling”. In basic configurations it is a simple plastic case with glass on a mechanical fastening, and in versions Ambiente, Elegance and Laurin & Klement added:

  • πŸ”Œ Electric adjustment drive (motors for changing the angle of inclination)
  • πŸ”₯ Heated glass (12V heating element)
  • πŸ”„ Folding mechanism (in versions with function Auto-Fold)
  • πŸš— Turn indicator (in mirrors with repeaters)

The mirror housing is attached to the door through three-point bracket, which often breaks when impacted. Inside there is a wiring harness (in electric versions), protected by corrugation - its damage leads to the failure of all functions. The glass is fixed with plastic latches or metal springs (depending on the year of manufacture).

What are the differences between the mirrors for facelift (2009–2013)?

In models Octavia A5 FL (after 2009) the shape of the mirror housing changed - it became more streamlined, and the turn signals received LED filling instead of incandescent lamps. Articles of glasses and cases for dorestayla and facelift not interchangeable!

Important: in mirrors with position memory (optional Memory Package) an additional control unit is used, which is synchronized with the key fob. When replacing such a mirror you will need adaptation via VCDS.

Articles and analogues: how not to make mistakes when purchasing

2. Disconnecting and dismantling the mirror

After removing the casing:

  1. Disconnect the power connector (press the latch and pull it down).
  2. Unscrew the three nuts 10 mm, attaching the mirror to the door (they are hidden under the rubber seal).
  3. Remove the mirror by pulling it on yourself (not up!).

⚠️ Attention: If the mirror cannot be removed, check whether the fourth nut has gone unnoticed (in some modifications it is hidden under the glass seal). Excessive force may break the bracket!

3. Installing a new mirror

When installing:

  • Check the integrity of the sealing rubber on the new mirror (if it is damaged, moisture will enter the interior).
  • Connect the connector up to fixing the mirror with nuts - this makes it easier to avoid distortion.
  • Tighten the nuts in a crisscross pattern to avoid distortion of the housing.

After installation, check:

  • πŸ”„ Operation of the electric drive (adjustment up-down, left-right).
  • πŸ”₯ Heating function (heating should be felt 1-2 minutes after switching on).
  • πŸš— The operation of the turn signal (if equipped).
πŸ’‘

If after replacement the mirror β€œhums” when adjusted, lubricate the drive gears with silicone grease (for example, Liqui Moly Silicon-Fett).

Typical faults and repair methods

Left mirror Octavia A5 Most often it fails for the following reasons:

1. Electric drive does not work

Symptoms: the mirror cannot be adjusted using the buttons, crackling or clicking noises are heard.

Causes and solutions:

  • πŸ”Œ Broken wire in the corrugation between the door and the body. Check the circuit with a multimeter (resistance should be ~0 Ohm).
  • βš™οΈ Gear wear in motors. The solution is to replace the drive (part number 1Z3857571).
  • πŸ’» Control unit failure. Requires diagnostics via VCDS (error 01550 β€” Mirror Adjustment Switch (E43)).

2. Heating does not warm up

Symptoms: the glass freezes, despite the heating being turned on.

Diagnostics:

  1. Check the fuse F37 (10A) in the block under the steering wheel.
  2. Measure the voltage at the connector contacts (should be ~12V when the heating is on).
  3. Ring the heating element (resistance ~1–2 ohms). If there is a break, replace the glass.

⚠️ Attention: If the heating stops working after washing, most likely water got into the connector. Dry it with a hairdryer and treat it WD-40 Contact Cleaner.

3. The mirror does not fold automatically

In models with Auto-Fold the problem often lies in:

  • πŸ”‹ Low battery (the function is disabled when the voltage is below 11.5V).
  • πŸ”§ Broken microswitch in the folding mechanism (article no. 1Z3857585).
  • πŸ“Ά Settings failure. Solution: Adapt via VCDS β†’ 46 (Comfort) β†’ Adaptation β†’ Channel 60.
πŸ’‘

If the mirror folds only manually, but does not return to its original position, the Hall sensor in the motor is to blame. Replacing it will cost less than buying a new mirror.

Adjustment and configuration after replacement

After installing a new mirror, you need it calibrate, especially if it is equipped with an electric drive or position memory. Here's how to do it right:

1. Mechanical adjustment (without electronics)

In basic versions, the angle of inclination is changed manually:

  1. Loosen the plastic nut on the back of the mirror (under the decorative trim).
  2. Adjust the position so that the rear wheel is visible in the lower corner and the horizon line in the upper corner.
  3. Tighten the nut while holding the mirror in position.

2. Electronic adjustment

In power mirrors:

  • Use the joystick on the driver's door (up/down - tilt, left/right - turn).
  • To reset the settings, hold the joystick in the extreme position for 10 seconds.
  • In versions with Memory Package maintain the position by holding the button M on the joystick.

⚠️ Attention: If the mirror β€œtwitches” when adjusted, this is a sign of wear on the gears. Do not delay repairs - over time, the motor will jam completely.

3. Function setting Auto-Fold

To fold the mirror when locking the car:

  1. Turn on the ignition.
  2. Hold the mirror fold button (on the joystick) for 5 seconds until you hear a beep.
  3. Turn off the ignition and check the operation (the mirrors should fold when you press the key fob).
How to disable auto folding?

To deactivate the feature Auto-Fold, repeat the setup procedure but hold down the fold button for 10 seconds. An audible signal will confirm the shutdown.

Frequently asked questions about the left mirror Octavia A5

Is it possible to put a mirror from the facelift on the pre-facelift?

No, mirrors not interchangeable due to the different shape of the body and fastenings. The exception is some analogues (for example, Hella), which are suitable for both options, but require modification of the connectors.

Why doesn't the heating work after replacing the mirror?

There are two reasons:

  1. Mismatch of connectors (for example, a 3-pin mirror was connected instead of a 5-pin).
  2. Fuse blown F37 due to short circuit when connecting.

Solution: Check the wiring diagram and replace the fuse.

How to remove mirror glass without breaking the latches?

Carefully pry the glass with a plastic spatula bottom corner (the first latch is usually located there). Then gradually release the remaining fasteners, moving in a circle. Do not use metal tools - they will scratch the plastic!

What to do if the mirror β€œhums” in cold weather?

This is a sign grease freezing in the drive mechanism. Solution:

  1. Warm up the mirror with a hairdryer (do not overheat the plastic!).
  2. Lubricate the gears with silicone grease (eg Molykote G-4500).
Is it possible to repair the adjustment motor?

Theoretically yes, but in practice it is unprofitable. The cost of a new motor (article 1Z3857571) - about 1,500 rubles, and repairs will cost almost the same amount. The exception is replacing gears if the engine itself is in good condition.
