Where are the fuse boxes located in Skoda Kodiaq

B Kodiaq provided two main fuse boxes:

• 🔧 F37 - located in the cabin, under the instrument panel from the driver's side. Responsible for basic electronics: lighting, multimedia, comfort systems.
• ⚡ F38 — located in the engine compartment, next to the battery. Controls power circuits: starter, generator, cooling fans.

There is also additional relay block under a plastic cover in the trunk (in versions with electric drive of the fifth door). To get to F37, you need:

1. Open the driver's door.
2. Click the plastic cover under the steering wheel (it is attached to two latches).
3. Unscrew two Torx T20 screws (if you have them in your configuration).
4. Carefully pull the block over yourself.

To access F38 you will need:

• Open the hood.
• Remove the protective cover of the battery (it is held on four clips).
• Disconnect the terminal "minus" (required!) to avoid short circuit.
• Click the block locks and lift it.

⚠️ Attention: If you have recently changed the battery or removed the terminals, the block F38 It can become “sticky” due to the oxidation of contacts. Don’t apply force – treat contacts with spray WD-40 and wait 5-10 minutes.

Decoding of block fuses F37 (salon)

Block F37 contains fuses and relays for most comfort and safety systems. Below is the table for Skoda Kodiaq 2017–2026 (including 2021 restyled). Please note that depending on the configuration (Ambition, Style, Sportline, RS) Some items may vary.

F25	20A	Central locking, immobilizer	If the car fails, it may not start.
F30	30A	Heated front seats	If the heating does not work, also check the relay J329
F45	15A	Multimedia system (MIB2/MIB3)	When replaced, the radio settings will be reset.

A complete diagram for your configuration can be found in instruction manual (section Electrical equipment → Fuses). If you do not have a paper version, download the electronic manual on the official website Škoda by link (select year and model).

⚠️ Attention: fuse F45 (15A) screen-manager MIB3. If the display does not turn on after replacing, check the connectors behind the block (they can oxidize from moisture).

How to check a fuse without a tester?

Remove the fuse and look at the light: if the thread inside is broken, it is burned out.

You can also replace it with a knowingly working with the same marking (for example, from the slot of the cigarette lighter). F58).

Decoding of block fuses F38 (under the hood)

Block F38 is responsible for power circuits and critical systems. The safety locks have a higher denomination (up to the 100A), and their replacement requires caution. Below are the key positions for Skoda Kodiaq with petrol (TSI) and diesel (TDI) engines:

Number	Ampere	Purpose	Features
F1	50A	Main relay (J271)	If the car fails, it will not start.
F3	80A	Generator	It burns out when you run out of voltage.
F10	30A	Radiator cooling fan	If the engine is overheated, the engine will overheat.
F15	40A	ABS/ESP	If it fails, it will light up. Check Engine and ESP
F20	30A	Fuel pump (gasoline)	If it burns out, the car will not start.

In diesel versions (2.0 TDI) the fuel pump safety lock is in position F22 (30A). Also pay attention to the relay J320 - It's responsible for the work of the spark plugs. If the car is not started “cold”, check it first.

To replace fuses in F38 use plastic tweezers (Combined with the car). Metal tools can close contacts!

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

Replacing a fuse seems like a simple procedure, but many make mistakes that lead to a loss of safety. burn-out or even fire. Follow this algorithm:

Turn off the ignition and remove the key from the lock |Find a faulty fuse (use the circuit above) |Remove it with plastic tweezers |Check the integrity of the filament in the light |Install a new fuse with the same nominal value |Check the circuit

-->

Important details:

• 🔍 Never use a safety lock with large denomination - this can lead to melting of the wiring.
• 🔧 If the new fuse blows immediately, look for short circuit In the chain (check the wires for rubbing).
• 💡 B Skoda Kodiaq from 2021, type fuses are used Mini Blade (slim) and Maxi Blade (broad). Don't confuse them!

If the fuse burns out again, do not try to replace it with a “bug” (wire or foil). It could be incapacitating. control unit (for example, BCM or ECU(b) which will be repaired at the cost of 30 000–100 000 ₽.

Typical faults and their causes

Owners Skoda Kodiaq Often faced with several “diseases” associated with fuses:

1. The lighter or USB port is not working. - the fuse is at fault F58 (20A) in the block F37. Often burns out due to the connection of powerful devices (for example, a compressor).
2. Headlights or side lights do not light up - check F7 (10A) and F8 (10A) in F37, as well as relay J357.
3. Trunk won't open - the safety lock is responsible F42 (20A) and relay J538.
4. The car does not start, the starter does not turn - check F1 (50A) in F38 main relay J271.

Another common problem is contact oxidation in the block F38. Due to moisture or salt reagents, the contacts are covered with a green coating, which leads to bad contact and the fuses burn out. Decision:

• 🧹 Clean the contacts with fine sandpaper (grain 1000–1500).
• 💦 Apply contact lubricant (for example, Liqui Moly Kontakt-Spray).
• 🔌 Check the tightness of the block cover - if it cracks, replace it.

If after cleaning the problem remains, contact the electrician - it is possible that the wiring or control unit is damaged.

Frequently asked questions about fuses Skoda Kodiaq

We have collected answers to the most popular questions from owners:

Can fuses from other cars (eg VW Tiguan) be used?

Yes, Skoda Kodiaq built on a platform MQB, as well as VW Tiguan, Audi Q5. The fuses and relays are identical. The main thing is the coincidence of the denomination and type (for example, Mini Blade).

Why did the radio stop working after replacing the fuse?
