Rear wiper on Ε koda Octavia A5 - a small but critical element on which visibility in rain or snow depends. Over time, the brush wears out, the motor fails, and the mechanism begins to creak or operate jerkily. If you notice that your rear window remains dirty even after several passes of the wiper, it's time to get to the bottom of the problem.

In this article we will look in detail all aspects of the rear wiper operation on Octavia A5 (including restyled versions 2009–2013): from choosing original and analog brushes to step-by-step motor replacement. You will learn how to diagnose faults, what spare parts articles are suitable specifically for your modification (depending on the body type - liftback or station wagon), and how to avoid common mistakes during repairs.

Design and principle of operation of the rear wiper on Octavia A5

Rear wiper on Octavia A5 consists of several key components:

  • πŸ”§ Wiper blade - the rubber part that is in direct contact with the glass. Over time, rubber hardens, cracks or wears off.
  • βš™οΈ Drive mechanism - includes a motor, gearbox and lever that transmits movement to the brush. B Octavia A5 An electric motor with a worm gear is used.
  • πŸ”Œ Electrical wiring and fuse β€” power goes through the fuse F36 (10A) in the mounting block (located under the steering wheel).
  • πŸ’§ Washer system - nozzle and tubes supplying liquid to the glass. In station wagons Combi the nozzle often gets clogged.

The operating principle is simple: when the lever on the steering column is activated (position I or II) current is supplied to a motor, which, through a gearbox, drives a lever with a brush. In position II The washer also turns on. If the wiper jerks or does not return to its original position, the problem most often lies in reducer gear wear or oxidation of motor contacts.

⚠️ Attention: On Octavia A5 with the system Rain Sensor (rain sensor) The rear wiper can be activated automatically when the ignition is turned on and precipitation is detected. If the wiper operates spontaneously, check the sensor settings in the menu MAXIDOT (if installed).
Component Service life (approximate) Symptoms of a problem
Wiper blade 1–2 years (or 20–30 thousand km) Streaks on glass, squeaking, incomplete cleaning
Drive motor 100–150 thousand km The wiper does not move, works jerkily, does not return to the parking position
Gearbox 80–120 thousand km Crunching noise when working, slow movement of the brush
Washer nozzle 5–7 years Weak fluid pressure, clogged holes

How to choose a rear wiper blade: original vs analogues

Rear wiper blade Octavia A5 has unique shape, so it is important to choose a compatible model. Original spare part from Ε koda goes under the article 1Z1 955 425 A (length 300 mm). However, its price is often too high (from 1,200 to 1,800 rubles), so many owners choose analogues.

When choosing an analogue, pay attention to:

  • πŸ“ Brush length - should be straight 300 mm. Shorter or longer options will not work.
  • πŸ”„ Mounting type - on Octavia A5 mount is used "Hook 9x3" (hook 9 mm).
  • 🌑️ Rubber material β€” it is optimal to choose brushes with a graphite coating (they last longer and do not creak).

Among the proven analogues:

  • πŸ”Ή Bosch 3397004665 - high-quality rubber, but may require trimming to length.
  • πŸ”Ή Valeo 699419 - a soft brush, cleans well, but is less durable.
  • πŸ”Ή SWF 1120003 - a budget option (from 400 rubles), but often requires replacement once a year.
⚠️ Attention: On restyled Octavia A5 FL (2009–2013) sometimes installed brushes with the article number 1Z1 955 425 B. They are visually identical, but have a different rubber hardness. Before purchasing, check your vehicle's VIN with your dealer.

Step-by-step instructions for replacing the rear wiper blade

Replacing the brush with Octavia A5 takes no more than 5 minutes and requires no tools. The main thing is to remove the old brush correctly without damaging the mount.

Algorithm of actions:

  1. Raise the wiper arm to a vertical position (perpendicular to the glass).
  2. Press the fastening latch (located on the side of the brush) and pull it towards you.
  3. Install the new brush, aligning the mount with the lever until it clicks.
  4. Lower the lever back onto the glass.

If the brush does not come off (the latch is jammed), do not use excessive force - use a flat-head screwdriver to gently press out the latch.

After installing the new brush, wipe it and the glass isopropyl alcohol - this will remove the factory grease and improve cleaning for the first few days.

Diagnosis of motor and gearbox faults

If the rear wiper is on Octavia A5 stopped working completely or moves intermittently, the problem most often lies in the motor or gearbox. Before purchasing new parts, perform diagnostics:

Checking the fuse and wiring:

  1. Open the fuse box (under the steering wheel, on the left).
  2. Check the fuse F36 (10A) - He is responsible for the rear wiper.
  3. If the fuse is intact, check the voltage at the motor contacts (there should be 12V with the wiper on).

Symptoms of a motor/gearbox malfunction:

  • πŸ”Œ The wiper does not respond when the lever is turned on.
  • πŸ”„ The brush moves jerkily or stops in an arbitrary position.
  • πŸ”Š A crunching or grinding noise is heard during operation.
  • πŸ”™ The wiper does not return to its original position.

If the motor shows no signs of life, but the fuse and wiring are in order, it will need to be replaced. The original motor goes under the article number 1K1 955 119 (price ~3,500 rubles). Among analogues they have proven themselves well Valeo (699420) and Febi (26296).

How to check the motor without removing it?

Connect the tester to the motor contacts (usually black and gray wires) and turn on the rear wiper. If there is voltage, but the motor does not work, it is faulty. If there is no voltage, the problem is in the wiring or switch.

Replacing the rear wiper motor: step-by-step analysis

Replacing the motor with Octavia A5 requires removal of the inner trim of the rear door (on a station wagon) or the hatch in the trunk (on a liftback). The process takes about 1–1.5 hours.

Required tools:

  • πŸ”§ Screwdriver T25 (for sheathing fastenings).
  • πŸ”§ Key on 10 mm (for mounting the motor).
  • πŸ”§ Plastic puller (to avoid damaging the clips).

Work order:

  1. Remove the rear door trim (on a station wagon) or the plastic panel in the trunk (on a liftback). Clips are fragile - handle with care!
  2. Disconnect the power connector from the motor.
  3. Unscrew the 3 motor mounting bolts (key on 10).
  4. Remove the old motor and install the new one, securing it with bolts.
  5. Connect the connector and check the operation of the wiper.
  6. Reinstall the trim by snapping all the clips into place.
⚠️ Attention: On Octavia A5 with the system Park Pilot (parking sensors) when removing the rear door trim, you can accidentally tear off the sensor wires. Before starting work, disconnect the battery!

When installing a new motor, do not forget to lubricate the gearbox lithium grease - this will extend its service life by 20–30%.

Rear window washer repair: cleaning the nozzle and tubes

If the washer fluid does not get onto the glass or splashes weakly, the problem is usually a clogged nozzle or pinched tubes. On Octavia A5 The rear window washer nozzle is located on the trunk lid (station wagon) or under the spoiler (liftback).

How to clean an injector:

  1. Remove the nozzle by prying it off with a flat screwdriver (clip-on fastening).
  2. Rinse it under running warm water, using a needle to clean out the holes.
  3. Blow with compressed air (for example, a compressor).
  4. Reinstall and check operation.

If the problem is in the tubes:

  • Check the integrity of the hoses from the washer reservoir to the nozzle.
  • Make sure that the tubes are not pinched by the trunk trim.
  • If necessary, replace the hoses (part no. 1J1 955 651 for Octavia A5).

If the washer does not work at all, check:

  • πŸ”‹ Washer pump (located in the reservoir, article no. 1J1 955 121).
  • πŸ”Œ fuse F25 (10A) (responsible for washers).
  • πŸ’§ Liquid level in the tank (sometimes the level sensor triggers falsely).

Common mistakes when repairing a rear wiper and how to avoid them

Many owners Octavia A5 face the same problems after repairing the wiper themselves. Here are the most common mistakes and how to prevent them:

1. Damage to trim clips during removal

Clips on Octavia A5 plastic and easy to break. To avoid this, use plastic puller and heat the clips with a hairdryer (they become more elastic). Spare clips: article number 1J1 868 249 A (set of 10 pcs.).

2. Incorrect brush installation

If the brush is installed crookedly, it will leave streaks or squeak. Always check that the mount clicked until the end. After installation, turn on the wiper and watch the trajectory of movement - it should be smooth.

3. Ignoring gearbox lubrication

When replacing a motor, many people forget to lubricate the gearbox. This leads to premature wear. Use lithium grease (for example, LIQUI MOLY Lithofluid).

4. Reversed polarity when connecting the motor

If you confuse β€œ+” and β€œβ€“β€ when connecting the motor, it will rotate in the opposite direction and the wiper will not return to the parking position. The connector is usually marked: 31 (weight) and 15 (food).

5. Using an incompatible brush

Brushes from other models VW Group (for example, from Golf V or Passat B6) may not be suitable in length or stiffness. Always check the article number 1Z1 955 425 A.

Frequently asked questions (FAQ)

Is it possible to install a frameless blade on the Octavia A5 rear wiper?

Technically yes, but it's not recommended. Frameless blades do not adhere well to the curved surface of the rear window Octavia A5, which leaves uncleaned areas. If you still want to experiment, choose models with flexible frame (for example, Bosch Aerotwin 3397004996), but be prepared for worse cleanup around the edges.

Why does the rear wiper work but does not stop in its original position?

This problem is related to limit switch malfunction in the motor or wear of the gearbox. Try manually returning the wiper to the park position (by gently pulling the lever). If the problem recurs, the motor or gearbox needs to be replaced. A temporary solution is to adjust the position of the lever on the motor slot (by loosening the fastening nut).

How often should you change the rear wiper blade?

Recommended interval - once every 1–2 years or every 20–30 thousand km. However, service life depends on operating conditions:

  • In regions with frequent precipitation and the use of washer, the brush wears out faster.
  • If the wiper often works β€œdry” (without washer), the rubber will harden in 6–12 months.
  • When parked outdoors, UV rays destroy the rubber, shortening its service life.

Check the condition of the brush every 5-6 months: if there are streaks on the glass or you hear a creaking sound, it’s time to change it.

Can the rear wiper motor be repaired or is it just a replacement?

In most cases, the motor only needs to be replaced, but there are exceptions:

  • If the problem is oxidized contacts, they can be cleaned and processed WD-40.
  • If worn out commutator brushes, they can be replaced (but this requires disassembling the motor).
  • If the winding burns out or the gear of the gearbox crumbles, just replace it.

Repair is justified if the motor is rare or expensive (for example, for versions with Rain Sensor). In other cases, it is cheaper and more reliable to install a new one.

Why does the rear wiper on the Octavia A5 only work when the lever is pressed, but not in constant mode?

This problem is related to burnt contacts in the switch (steering column lever) or relay malfunction J317 (wiper relay). Try:

  1. Remove the steering column switch and clean the contacts (use contact lubricant).
  2. Check relay J317 in the mounting block (located under the dashboard).
  3. If the problem persists, the comfort control unit may be faulty (BCM).
