Owners Škoda Kodiaq 2020 models sooner or later have to 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, finding the right fuse in a block without a diagram is not an easy task: in Kodiaq There are more than 80 of them installed, scattered across several mounting blocks.

In this article you will find detailed diagrams of fuses and relays for Škoda Kodiaq 2020 model year, including their purpose, ratings and visual cues. We'll also look at how to properly remove and install fuses to avoid damaging contacts, and give tips on troubleshooting. Particular attention is paid common mistakesthat owners allow when working with car electrical systems.

Where are the fuse boxes in the Škoda Kodiaq 2020

B Kodiaq 2020 fuses and relays are distributed over three main mounting blocks. Their location depends on the configuration and supply market, but in most cases the schemes are unified:

  • 🔧 Main fuse box — located in the cabin, under the instrument panel on the driver's side. Access to it opens after removing the decorative cover (pull it towards you).
  • 🚗 Relay and fuse box in the engine compartment — located next to the battery, under the plastic cover. The elements responsible for power electrics (starter, generator, fans) are concentrated here.
  • 🔌 Additional block — in some trim levels it is installed behind the glove compartment or under the rear seat (for example, for system fuses Climatronic or audio systems Canton).

It is important to consider that in Kodiaq with diesel engines (2.0 TDI) and gasoline (1.5 TSI, 2.0 TSI) block diagrams may differ slightly. For example, diesel versions have added fuses for the system AdBlue and glow plugs.

⚠️ Attention: Before working with fuses, be sure to turn off the ignition and remove the battery terminal (negative). B Kodiaq 2020, some circuits remain energized even when the ignition is turned off, which can lead to a short circuit.

How to check a fuse without a tester?

If you don’t have a multimeter at hand, you can visually inspect the fuse using light: the blown thread will be broken. You can also use the “replacement method” - install a known-good fuse of the same rating from another circuit (for example, a cigarette lighter).

Explanation of the fuse box in the engine compartment

Block in the engine compartment Kodiaq is responsible for critical systems: starting the engine, charging the battery, operating fans and the fuel pump. Here fuses of increased rating are used (up to 100A), therefore they must be replaced strictly with similar ones - installing a fuse of a lower rating will lead to its immediate blowout, and a larger one will lead to the risk of fire.

  • ⚡ F1 (50A) — Main relay of the engine control system (ECU). If it burns out, the engine will not start.
  • ⚡ F3 (60A) — Electric cooling fans. If the fuse is blown, the engine will overheat.
  • ⚡ F7 (30A) — Fuel pump. Symptoms of malfunction: the engine stalls or does not start.
  • ⚡ F10 (80A) — Generator. When the battery fails, the battery does not charge and lights up on the dashboard. Battery.

In diesel versions Kodiaq 2.0 TDI a fuse has been added to the engine compartment F15 (50A) for the system AdBlue. Its burnout leads to failure of the exhaust gas purification system and activation of the engine emergency mode.

⚠️ Attention: Fuses F1 and F10 in the engine compartment are often confused due to their close location. When replacing check the diagram carefully - an error can lead to failure ECU or generator.

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

Replacing the fuse in Škoda Kodiaq - The procedure is simple, but requires accuracy. Here is an action algorithm that will help you avoid mistakes:

  1. Identify the faulty circuit. For example, if the windshield wipers do not work, look for a fuse marked Wiper or F36 (in the salon block).
  2. Find the fuse in the diagram. Use the tables above or the manual. B Kodiaq A short explanation is often printed on the block cover.
  3. Remove the fuse. To do this, use plastic tweezers (usually attached to the block cover). Do not use metal objects - they may short-circuit the contacts.
  4. Check integrity. A burnt-out thread inside the fuse will be torn or melted. If the fuse appears to be OK, check it with a multimeter in calls.
  5. Install a new fuse. He must be same denomination and color. For example, 10A - red, 20A - yellow.

If the new fuse blows immediately, this indicates short circuit in the circuit. In this case, you need to contact the service for diagnostics. Searching for short circuits on your own without experience can result in damage to the wiring.

💡

B Kodiaq 2020, there is often a spare set of fuses in the glove compartment (in a plastic case). If you don’t have it, buy a kit in advance - this will save time in case of breakdown.

Common fuse problems and their solutions

Owners Škoda Kodiaq 2020 are often faced with common faults related to fuses. Here are the most common of them and how to eliminate them:

  • 🔋 The cigarette lighter fuse often blows (F42, 20A).

    Reason: connection of powerful consumers (for example, a compressor or inverter). The solution is to use a fused power strip or connect devices directly to the battery.

  • 🚨 After replacing the fuse F1 in the engine compartment the car will not start.

    Cause: The fuse may be of the wrong size or the main relay may be damaged. The solution is to check the relay J271 (located nearby).

  • 🎵 Audio system not working, fuse F25 intact

    Reason: the problem may be in the relay J519 (multimedia control unit) or a break in the wiring to the antenna. Solution - diagnostics with a scanner VCDS.

If the fuse blows again, don't increase its value - this may cause a fire. Instead:

  1. Check the circuit for short circuit (use multimeter in 200Ω).
  2. Inspect the wiring for chafing or melting (especially in areas where it passes through the body).
  3. Contact the service to check the consumers in the circuit (for example, the windshield wiper motor or fan).
💡

If in Kodiaq several systems have stopped working at the same time (for example, lighting and multimedia), the problem may be main fuse (F63, 100A) or in the control unit BCM. Self-repair is unacceptable here - diagnostics are required at the service center.

FAQ: Frequently asked questions about Škoda Kodiaq 2020 fuses

Is it possible to replace the fuse with a bug (wire) in an emergency?

No, this is extremely dangerous! The “bug” has no protective properties and can lead to melted wiring or a fire. B Kodiaq 2020, it is especially critical not to use homemade fuses in circuits ECU, AdBlue and generator - this is fraught with failure of expensive components.

If you urgently need to get to the service, temporarily use the fuse smaller denomination (for example, instead of 20A put 15A), but immediately after the trip replace it with a standard one.

Why after replacing the fuse F30 (heated seats) does it burn out again?

This indicates short circuit in heating circuit. Most often the problem lies in:

  • Damaged heating element inside the seat (frayed or melted).
  • Faulty heating control unit (J774).
  • Short circuits in the connectors under the seat (check the contacts for oxidation).

For diagnostics, disconnect the connectors of the heating elements and check the circuit with a multimeter. If the fuse does not blow, the problem is in the seats.

Which fuse is responsible for the rear view camera in Kodiaq 2020?

The rear view camera is connected to the fuse F48 (10A) in the salon block. He is also in charge of the system Park Assist and parking sensors. If the camera does not work after replacing the fuse, check:

  1. Camera connector (located under the trunk trim).
  2. Media Settings: Sometimes the camera is disabled in the menu CAR → Camera.
  3. Control unit J772 (may require flashing).
What to do if there is a fuse in the engine compartment F3 (60A) melted and cannot be removed?

If the fuse is stuck to the contacts, do not try to pull it out with pliers - this will damage the connector. Proceed like this:

  1. Disconnect the battery.
  2. Treat contacts with spray WD-40 or Liqui Moly Kontakt and wait 10 minutes.
  3. Gently wiggle the fuse with plastic tweezers or a screwdriver with an insulated handle.
  4. If that doesn't help, remove the entire fuse box (unscrew the 2 bolts Torx T20) and clean the contacts with fine sandpaper.

After removal, check the integrity of the sockets - if they are melted, the unit must be replaced.

Can fuses from other VW Group models (eg Tiguan or Passat) be used?

Yes, but with reservations:

  • Fuses standard denominations (5A–30A) interchangeable with other models VW, Audi and Škoda (for example, from Tiguan or Superb).
  • Fuses increased denomination (60A–100A) may vary in size. For example, in Passat B8 more compact fuses are used MegaFusewhich are not suitable for Kodiaq.
  • Relays are also interchangeable, but their contacts must match in location (for example, relay J317 from Golf 7 suitable for Kodiaq).

Before use, visually compare the dimensions and markings.
