ŠKODA Kodiaq 2020 fuses: complete diagram, assignment and step-by-step replacement

ŠKODA Kodiaq 2020 is a modern crossover with complex electronics, where each element is protected by fuses. Failure of even one of them can result in non-functioning headlights, power windows or multimedia system. Unlike previous generations, in Kodiaq 2020 There are two main fuse boxes: one under the hood, the other in the passenger compartment. However, their location and numbering may differ depending on the configuration (for example, Ambition, Style or Sportline).

In this article you will find current fuse diagrams for Kodiaq 2020 with a decoding of each element, step-by-step instructions for replacement, as well as typical mistakes that owners make. We will not limit ourselves to general phrases - here we only have specific data confirmed by the manufacturer’s manuals and the experience of service centers. For example, you will find out why fuse F37 (10A) is responsible for the operation of the rear view camera only in configurations with the system Park Assist, and how this affects fault diagnosis.

Where are the fuse boxes located in ŠKODA Kodiaq 2020

B Kodiaq 2020 fuses are distributed over two main blocks and one additional (depending on the configuration). Their location is dictated by the manufacturer’s logic: critical circuits (for example, the engine control system) are placed under the hood, and fuses for comfort options (climate control, audio system) are located in the cabin.

Here are the exact coordinates:

• 🔧 Main unit in the cabin: to the left of the steering column, behind the plastic cover. To gain access, pull the recess at the bottom of the panel (next to the clutch pedal). In some configurations, the cover is secured with a latch; it must be carefully pryed off with a screwdriver.
• 🚗 Block under the hood: next to the battery, in a plastic box with an inscription FUSES. On models with diesel engines (2.0 TDI) the box can be moved closer to the windshield.
• ⚡ Additional block (if equipped): in the trunk, under the floor, next to the spare tire. Only present in versions with 3-zone climate control or system Area View (all-round view).

Important: on Kodiaq 2020 with a hybrid installation (1.4 TSI e-TEC) the fuse diagram under the hood is different - a separate block for high-voltage circuits has been added there (only a service center has access to it).

Diagram and decoding of fuses in the cabin block

The cabin unit contains fuses for most comfort and multimedia systems. Their numbering starts with F1 and ends F60, but not all positions are filled - some are reserved. Below is a table with most in demand fuses (for a complete diagram, see the manual for your equipment).

Fuse number	Rating (A)	Purpose	Notes
F5	10	Airbag control unit (Airbag)	When replacing, be sure to disconnect the battery for 10 minutes!
F12	15	Central locking, alarm	Often burns out due to a short circuit in the door wires
F23	20	Audio system (Bolero/Columbus)	Responsible for powering the screen, but not for navigation
F37	10	Rear view camera, parking sensors	Only available with Park Assist
F45	25	Heated front seats	When replacing, check the thermostat in the seats

Please note: in versions with Virtual Cockpit fuse added F58 (10A), responsible for powering the digital instrument panel. Its failure may lead to "blind" launch engine (without speedometer and tachometer readings).

⚠️ Attention: fuse F12 (15A) often confused with F13 (10A), which is responsible for interior lighting. If after replacement the central locking does not work, check relay K32 - it is located nearby and can stick when wet.

Engine compartment fuse box: what you need to know

Block under the hood Kodiaq 2020 contains fuses for critical systems: engine, transmission, lighting, ABS. Here fuses of increased rating are used (up to 100A), and replacing them requires caution - incorrect actions can lead to a fire in the wiring.

Key Features:

• 🔥 Fuses S1-S10 (large size) protect power circuits. For example, S5 (80A) is responsible for the generator, and S8 (60A) - for the cooling fan.
• ⚡ Fuses F1-F30 (small) duplicate part of the salon chains, but with a different denomination. For example, F7 (30A) under the hood protects the chain ESP, whereas in the salon he is responsible for it F28 (10A).
• 🛠️ To replace fuses S-series You will need special tweezers (included with the machine) or pliers with insulated handles.

Important nuance: on Kodiaq with diesel engines (2.0 TDI) a fuse has been added to the engine compartment F19 (20A) for the system AdBlue. Its failure results in an error P20EE on the dashboard and the inability to start the engine after 3-5 attempts.

What should I do if the fuse blows again?

If the fuse blows again after replacement, this indicates a short circuit in the circuit. B Kodiaq 2020 common reasons:

- Damage to the insulation of wiring in doorways (especially at the rear doors).

- Corrosion in the connectors of the control unit (ECU) — check the contacts for oxidation.

- Consumer malfunction (for example, window lift motor or heater fan).

In such cases, diagnostics with a multimeter or contacting service is required.

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

Replacing the fuse in ŠKODA Kodiaq 2020 requires care, especially when it comes to blocks under the hood. Here step-by-step algorithm, which minimizes risks:

1. Turn off the ignition and remove the terminal from the battery (minus). This will prevent short circuits when replacing.

2. Find the faulty fuse. B Kodiaq 2020, a blown fuse is visually different - its metal thread will be torn or melted. If in doubt, use a tester (ring the circuit).

3. Remove the fuse with special tweezers (located in the fuse box) or pliers. Do not use metal objects - it may cause damage make nests.

4. Install a new fuse same denomination. Increasing amperage (for example, with 10A on 15A) will result in a risk of fire!

5. Connect the battery and check the system operation. If the fuse blows again, look for a short circuit.

Serviceability of the new fuse (no cracks, corresponds to the rating)

No moisture in the fuse box

Integrity of wiring near the block

Correct battery connection (plus/minus)

-->

Pay special attention to fuses F23 (20A) and F45 (25A) - they often fail due to power surges when connecting external devices (for example, a DVR to a cigarette lighter).

⚠️ Attention: On Kodiaq 2020 with system Keyless (keyless entry) fuse F15 (10A) is responsible for the operation of the immobilizer antenna. Replacing it with the ignition on may lead to engine start blocking (key retraining will be required in the service).

Typical faults and their causes

Owners ŠKODA Kodiaq 2020 are often faced with repeated blown fuses. This is not an accident, but a consequence of design features or operating errors. Let's consider most common cases:

1. Fuse F12 (15A) (central locking)

• 🔑 Reason: Short circuit in door lock wiring. Most often the problem is in the right rear door - there is a wiring harness that frays when opening/closing.
• 🛠️ Solution: Disassemble the door trim, check the insulation of the wires (especially orange and black). If necessary, replace the harness or use heat shrink tubing.

2. Fuse F23 (20A) (audio system)

• 🎵 Reason: Connecting non-standard devices (amplifiers, subwoofers) without a safety relay. The block itself may also be to blame. Columbus — its board is sensitive to voltage drops.
• 🔌 Solution: Check the circuit with a multimeter, disconnect all external devices. If the problem persists, reset your media settings via Settings → System → Reset.

3. Fuse S5 (80A) (generator)

• ⚡ Reason: Worn generator brushes or faulty diode bridge. On Kodiaq 2020 this is manifested by dim headlights and an error Battery Management on the dashboard.
• 🔧 Solution: Check the voltage at the battery terminals (should be 13.8–14.4V with the engine running). If the value is lower, the generator requires repair.

How to check a fuse without a tester

Not everyone has a multimeter at hand, but check the fuse in Kodiaq 2020 is possible without it. Here three reliable ways:

1. Visual inspection

Remove the fuse and look at the light: if the metal thread inside is torn or melted, it is faulty. However, this method is not always accurate, since sometimes the breakage occurs inside the housing.

2. Replacement with a known good one

Take a fuse of the same rating from the spare socket (for example, F60 usually free) and install it in place of the suspect. If the device works, the problem is in the fuse.

3. Check for spark

Carefully touch the fuse terminals with a metal object (for example, a key) with the ignition on. If there is a spark, the fuse is good. Be careful: This method is risky as it may damage the electronics!
