Rear left door Ε koda Octavia A7 (2013–2020) – a knot that often requires attention due to mechanical damage, electronics problems, or seal wear. Unlike the front doors, the rear have their own design features: a different window lift mechanism, a different wiring connection scheme and specific mounting points. Owners Octavia A7 face typical problems - from creaking hinges to failure of the blocker or icing of glass in the cold. In this article, we will discuss everything you need to know: from choosing a new door (original vs. analogue) to step-by-step instructions for dismantling and repair.

We will pay special attention spare partsAs the left-hand back door is for Octavia A7 has several modifications depending on the configuration (for example, the presence of an electric glass drive or a pressure sensor in tires). We'll see. hidden problems, which occur after an accident or unskilled repairs - for example, skewed door due to deformation of the hinge or corrosion in the places of attachment of the seal. If you are planning a replacement or repair yourself, here you will find checklists, connection schemes and tips for saving without loss of quality.

Rear left door design Octavia A7: what's inside?

Rear left door Ε koda Octavia A7 (body 5E) consists of several key components, each of which may fail:

  • πŸ”§ Door frame - steel base with anticorrosion coating. In places of attachment of hinges and locks, rust often appears, especially after winter operation.
  • ⚑ Electrical wiring - a bundle of wires going from door to body through a corrugated hose. V Octavia A7 It's often rubbed at the base of the loop.
  • πŸšͺ Window lifter mechanism - in the basic versions of the cable, in the top - rack. The latter is more reliable, but more expensive to repair.
  • πŸ”’ Lock and blocker - includes a micro-switch that signals the closed state of the door. When it breaks, the indicator "door open" is on the device.
  • 🌑️ Sealant - a rubber gasket around the perimeter. Over time, it sank, which leads to drafts and icing of glass.

The difference between the rear door and the front door is the absence of a speaker and control buttons windows (they are located only on the driver's door). However, in versions with comfort rear doors are equipped with proximity sensors for function Keyless Entry. Also integrated in the door tire pressure sensor (if the car is equipped with a system TPMS), which is attached to the wheel through a metal nipple.

What is corrugated wiring and why does it break?

Corrugated hose is a flexible channel that protects wires running from door to body. V Octavia A7 She often breaks up because of:

1. Natural wear (rubber blubbers in the cold).

2. Mechanical damage when opening the door at a large angle (for example, when parking in a narrow space).

3. Incorrect installation after repair (wires twisted or stretched).

When corrugated, the wires are rubbed, which leads to a short circuit or failure of the electronics of the door (window, lock).

Typical faults and their causes

Rear left door Octavia A7 Most often it breaks down because of:

  1. Screaming or knocking at opening - the reason for wear of the hinges or lack of lubrication. In 80% of cases, the processing of loops helps WD-40 or Liqui Moly Silber-Spray.
  2. Window lifter doesn't work - either the motor or the cable (in the cable mechanisms) is to blame. Rack mechanisms break less often, but their repair is more expensive.
  3. The door is not locked. - a problem in the lock microswitch or a wiring break in the corrugated. Diagnosed by a multimeter (chain vertebrae).
  4. Ice-ice from the inside - a sign of depressurization of the seal or clogged drainage holes at the bottom of the door.
  5. The "door open" indicator is constantly on - a broken sensor in the lock or oxidized contacts.

Critical problem: if the door after an accident opens with difficulty or jams, do not try to close it by force - this can deform the hinges and lead to the need to replace the door assembly. In such cases, geometry adjustment or hinge replacement is required (5E1837101A and 5E1837102A for the upper and lower respectively).

Before buying a new door, check the condition of the hinges on the old one – if they are deformed, they will need to be replaced, otherwise the new door will close loosely.

Step-by-step instructions: how to remove the rear left door

To dismantle the door, you will need:

  • πŸ”§ Socket wrench T30 (for hinge bolts).
  • πŸ”§ Flat blade screwdriver (for removing trim).
  • πŸ”§ Plastic clips (5E0868243) 2-3 pieces to replace broken ones.
  • πŸ”§ Insulation (for fixing the wiring).

Sequence of actions:

  1. Disconnect the battery (remove the negative terminal) to avoid short circuit when handling wiring.
  2. Remove the door trim:
    • Put a screwdriver around the plastic cap near the opening handle.
    • Unscrew the two screws under the plug.
    • Carefully pull the skin over yourself, starting from the lower corner (clips are fragile!).
  3. Disconnect the wiring:
    • Disconnect the power pads of the window and lock.
    • Pull the corrugated from the body, previously removing the fixture (plastic clamp).
  4. Unscrew the hinges:
    • Put the door down (for example, a jack with a wooden pad).
    • Unscrew two bolts on each loop (top and bottom).
  • Remove the door - lift it up and pull it on you.

    Repair vs. replacement: which is more profitable?

    Rear left door repair cost Octavia A7 depends on the nature of the failure:

    • πŸ”§ Replacing the seal β€” 1,500–2,500 rubles (with work). It’s cheaper to do it yourself (the seal costs ~1,200 rubles).
    • ⚑ Wiring repair β€” 3,000–5,000 rubles. If the corrugation is damaged, it is better to replace it entirely (5E0971931A).
    • πŸšͺ Replacing a window regulator β€” 6,000–8,000 rubles (with work). In cable mechanisms, it is often enough to replace the cable (~2,000 rubles).
    • πŸ”’ Castle repair β€” 2,500–4,000 rubles. If the microswitch is broken, it can be replaced separately (~1,500 rubles).
    • 🎨 Painting the door β€” 10,000–15,000 rubles (with preparation and varnishing). Relevant for scratches or corrosion.

    Replacing the door assembly will cost 25 000–40 000 β‚½ (with work and painting). It is more profitable to repair if:

    • Only one component is damaged (for example, window regulator or seal).
    • The door frame is not deformed (no dents or rust).
    • The electronics operate stably (no breaks in the corrugation).

    ⚠️ Attention: If the door has been in an accident, even after repair, problems with the geometry may arise - it will close poorly or squeak. In such cases, it is more advisable to buy a new door, especially if the car is under warranty (otherwise the insurance payment may be denied).

    πŸ’‘

    Door repair is beneficial in case of local breakdowns (window lifter, seal, lock). Replacement is justified in case of serious damage to the frame or after an accident.

    How to avoid problems: prevention and care

    To the rear left door Octavia A7 lasted longer, follow the recommendations:

    • 🧴 Lubricate the hinges 2 times a year (spring and autumn) Liqui Moly Silber-Spray or CRC 2-26. Avoid WD-40 β€” it washes away the factory lubricant.
    • 🌑️ Clean drain holes at the bottom of the door (under the seal). A blockage leads to moisture accumulation and corrosion.
    • ⚑ Check the wiring corrugation at every maintenance. If you notice cracks, replace it before the wires break.
    • πŸ”’ Don't slam the door - this deforms the hinges and seal. Close it smoothly, pressing until the lock clicks.
    • 🎨 Treat with anticorrosive hinge attachment points and the bottom edge of the door (especially after washing in winter).

    If the door begins to creak or close poorly, do not delay diagnosis. For example, hinge wear at an early stage it can be eliminated by adjustment (tightening the bolts), and in advanced cases replacement will be required (5E1837101A and 5E1837102A). The same applies to the seal - replacing it at an early stage will prevent icing of the glass and corrosion of the frame.

    FAQ: answers to frequently asked questions

    Is it possible to install a rear door from Octavia A5 on A7?

    No, the doors are not interchangeable. U Octavia A7 (body 5E) different hinge geometry, glass shape and wiring fastenings. Even if the door is physically in place, the electronics (window lifter, lock) will not work.

    How to check if the microswitch in the lock is working?

    Connect the multimeter in dialing mode to the contacts of the microswitch (connector T2 on the lock wire). When the door is closed, the resistance should be ~0 Ohm, when open it should be infinity. If the readings do not change, the switch is faulty.

    What to do if the rear door window does not go up, but the motor is humming?

    Most likely, the problem is in the window lift cable (it broke or came off the guides). In rack and pinion mechanisms, the plastic gear may be broken. The solution is to disassemble the door and replace the cable (5E1857507A) or the entire mechanism.

    How to adjust the rear door if it sags?

    Sagging occurs due to wear on the hinges. To adjust:

    1. Loosen the top and bottom hinge bolts (socket wrench T30).
    2. Raise the door to the desired level (it should close without force).
    3. Tighten the bolts in a crisscross pattern, starting at the bottom hinge.

    If the play remains, the hinges require replacement.
