Owners ŠKODA Octavia 2019 release (restyled version A7 FL) sooner or later they face the need to check or replace fuses. These small but critical elements protect the vehicle's electrical circuits from overloads and short circuits. However, find the correct fuse in Octavia not so simple: installed in the car three main blocks (in the cabin, under the hood and an additional one in the trunk), and their layouts often differ depending on the configuration and sales market.

In this article we will look at exact locations of all fuse boxes in ŠKODA Octavia 2019, we will provide a breakdown of each element indicating the current strength, and also explain in detail how to correctly diagnose and replace blown fuses. We will pay special attention typical mistakes that owners make when working with electrical equipment - for example, using fuses of the wrong rating or ignoring signs of a relay malfunction. If your radio stops working, your headlights don’t light up, or your power window fails, these instructions will help you quickly find and fix the problem.

Where are the fuse boxes located in ŠKODA Octavia 2019?

B Octavia A7 FL (2019) there are three main locations for fuses and relays. Their location depends on the configuration, but in 90% of cases the layout is standard:

  • 🚗 Main unit in the cabin — located to the left of the steering column, behind the protective cover. The fuses for most consumers are concentrated here (lights, multimedia, climate control).
  • 🔧 Block under the hood — located next to the battery (in a plastic box). Responsible for high-voltage circuits: starter, generator, cooling fans.
  • 📦 Additional unit in the trunk - found in versions with all-wheel drive (4x4) or in cars with advanced electrics (for example, heated seats or a panoramic roof).

Important: in some trim levels Octavia RS or Scout a fourth unit can be installed under the rear seat. He is responsible for additional equipment such as adaptive cruise control or foot lighting. If you do not find the required fuse in the standard locations, check the technical documentation for your modification.

Diagram and decoding of the cabin unit fuses

The interior unit is the most popular, as fuses for everyday functions are concentrated here. To access it, follow these steps:

  1. Open the driver's door and kneel down.
  2. Locate the plastic cover to the left of the steering wheel (under the instrument panel).
  3. Carefully pry it off with a screwdriver or your fingers - it is secured with latches.
  4. Remove the cover and you will see the fuse and relay box.

Below is a table with a breakdown of fuses for ŠKODA Octavia 2019 (version A7 FL, European version). Please note that numbers may vary by market (e.g. Octavia for Russia or USA).

Number Ampere (A) Purpose Note
F1 5 Interior lighting, glove compartment lighting Often burns out when installing LED lamps
F10 10 Climate control unit In the event of a malfunction, the temperature may be reset
F25 15 Audio system (Bolero, Amundsen, Columbus) Check if there is no sound or screen freezes
F30 20 Window lifters (all doors) If several glasses do not work at once, check the relay K30
F45 25 Heated seats (driver/passenger) Burns out due to a short circuit in the heating elements

To accurately identify the fuse, pay attention to markings on the inside of the block cover — the current diagram is usually shown there. If your Octavia equipped with a system Virtual Cockpit, the fuse for it can be located in a separate slot (most often F50 on 10A).

Fuse box under the hood: what you need to know?

Engine compartment block ŠKODA Octavia 2019 is responsible for critical systems: starting the engine, charging the battery and operating the main actuators. Its location:

  • 🔋 Next to the battery (in a plastic box with latches).
  • 🔌 In some versions - under the cover, which is marked with the symbol "+".
  • ⚡ In diesel versions (2.0 TDI) there may be an additional unit for the fuel pump.

The peculiarity of this block is the presence high voltage fuses (from 80A up to 150A), which protect the generator and starter circuits. Replacing them requires caution: never use metal objects to remove them, as this may cause a short circuit. Useful for work plastic tongs from the car kit or a special puller.

⚠️ Attention: If the fuse in the engine compartment has blown F1 (150A), this may indicate a faulty alternator or battery. Do not replace it without diagnostics — there is a high risk of damaging the car’s electronics.

Below are the key fuses for the engine compartment for Octavia 2019 with gasoline engine 1.4 TSI:

  • 🔥 F1 (150A) — Generator main fuse.
  • ⚡ F5 (80A) - Starter circuit.
  • 💡 F10 (30A) — Engine control unit (ECU).
  • ❄️ F15 (40A) — Cooling fans (burns out when the fan motor jams).
What should I do if the fuse blows again?

If the fuse blows again after replacement, this indicates short circuit in the chain. In this case:

1. Do not install a fuse of a larger rating - this may cause a fire in the wiring.

2. Check the wires for melted or damaged insulation (especially in kinks).

3. If the problem is in the relay, replace it (the relay often “sticks” when overheated).

4. For diagnosing complex circuits (for example, ADAS or Parktronic) contact an electrician with a scanner VCDS (VASE).

How to properly replace a fuse: step-by-step instructions

Replacing the fuse in ŠKODA Octavia - a simple procedure, but requiring accuracy. Follow this algorithm to avoid errors:

  1. Turn off the ignition and remove the key from the lock. This will prevent accidental shorting.
  2. Find the faulty fuse according to the scheme (see previous sections).
  3. Use tweezers included with the unit - do not try to remove the fuse with your fingers or metal tools.
  4. Check integrity: if the thread inside is broken or the body is melted, the fuse must be replaced.
  5. Install new with same denomination. For example, if you burn out 10A, put 15A you can't!
  6. Check circuit operation after replacement. If the problem persists, look for a short circuit.

An important nuance: in Octavia 2019 standard size fuses are used Mini (APM/ATM) and Maxi (for high voltage circuits). You can buy them at any auto store, but it is better to take original ones from VW Group (articles: N 105 567 02 for 5A, N 105 567 04 for 15A etc.).

⚠️ Attention: If after replacing the fuse there is a smell of burning or smoke - disconnect the battery immediately and contact service. This is a sign of fire in the wiring, which can lead to a fire.
💡

Before replacing a fuse, take a photo of its location in the block with your phone. This will help you avoid mixing up the parts when reinstalling them, especially if you removed several pieces to check.

Typical problems with fuses in Octavia 2019 and their solutions

Owners ŠKODA Octavia A7 FL often encounter repeated faults related to fuses. Here are the most common cases and how to resolve them:

  • 🔊 The audio system does not work (Bolero/Amundsen):

    Check fuses F25 (15A) and F26 (10A). If they are intact, but there is no sound, reset the radio settings via Settings → System → Reset.

  • 🚪 Power windows don't work:

    The culprit is the fuse. F30 (20A) or relay K30. If the replacements do not help, check the door gear motors (the guides often become sour).

  • 💡 Headlights do not light (low/high beam):

    The fuses are responsible F7 (10A) (left headlight) and F8 (10A) (right). If the lamps are working and the fuses are intact, the problem is in the light control unit (BCM).

  • ❄️ Climate control does not work:

    Check F10 (10A) and F11 (5A). If the climate display shows an error "A/C Off" — the freon pressure sensor may have failed.

The problem with cigarette lighter fuse (F40, 20A). B Octavia 2019 it often burns out due to the connection of powerful devices (for example, compressors or DVRs with a voltage higher than 12V/10A). The solution is to use a splitter with a separate fuse or connect devices via USB port (if it supports enough power).

💡

If in your Octavia after replacing the fuse, another system stopped working (for example, the wipers turned off when replacing the radio fuse), which means you installed it in the wrong slot. Always check the diagram on the unit cover!

Relay in ŠKODA Octavia 2019: how to distinguish from fuses and when to change

Along with fuses in blocks Octavia installed relay — electromechanical devices that control the activation of powerful consumers (for example, fans, starter or heated windows). Externally, relays are easy to distinguish: they are larger than fuses and have a plastic case with legs.

The main signs of a faulty relay:

  • 🔊 Clicks without operation (for example, you can hear the fan relay clicking, but the blades do not spin).
  • 🔥 Burnt contacts on the relay legs (visible when removed).
  • 🚗 System failure with a working fuse (for example, the turn signals do not work, although the fuse is intact).

B Octavia 2019 most problematic relays:

  • K30 — Window lifters (wears out from frequent use).
  • K35 — cooling fan (overheats in traffic jams).
  • K50 — fuel pump (in diesel versions).

To replace a relay, simply remove the faulty one and install a new one with the same marking. Original relays from VW have articles like 4H0 951 253 (for K30). When purchasing analogues, choose a relay with the same parameters (voltage 12V, operation current).

Frequently asked questions about fuses ŠKODA Octavia 2019

Is it possible to use fuses of a higher rating if the original ones often blow out?

No! Installing a fuse with a higher rating (for example, 20A instead of 10A) can lead to wiring fire. If the fuse blows repeatedly, look for the cause - usually a short circuit or a faulty consumer (for example, a window lift motor).

Where to find a fuse diagram for your configuration Octavia?

The diagram is printed on the inside of the fuse box cover. If it is not there, download the instruction manual for your modification on the website ŠKODA (section "Manuals") or use the database ETKA (for dealers).

What should I do if another system stops working after replacing the fuse?

Most likely you installed the fuse in the wrong slot. B Octavia 2019 some circuits are connected through common relays. Check the correct installation according to the diagram and, if necessary, swap fuses.

How to check a fuse without removing it from the block?

Can be used multimeter in call mode:

  1. Set the multimeter to diode (or resistance) test mode.
  2. Touch the probes to the fuse contacts.
  3. If the readings 0 ohm - the fuse is OK. If OL (break) - burned out.

Which fuses are responsible for the rear view camera and parking sensors?

B Octavia 2019 with the system Parktronic:

  • Rear view camera - fuse F42 (10A) (in the salon block).
  • Ultrasonic Sensors - Fuse F15 (5A) and relay K12.

If the camera does not work after replacing the fuse, check the connector on the rear door - the contacts often oxidize.
