ŠKODA Superb fuses: location, diagram and replacement details

Fuses in ŠKODA Superb - these are small but critical elements on which the operation of all electrical equipment of the car depends. From the interior lighting to the ABS system, each circuit is protected by a separate fuse, and its failure can lead to either a harmless failure of the glove compartment lighting or the complete immobilization of the car. In this article we will look at where to look for fuse blocks in Superb different generations (including restyled versions), how to check and change them correctly, and also reveal hidden nuances, which are not written about in official manuals.

We will pay special attention Superb III (B8, FL) - the most common generation on the Russian market. Here the fuse system has become more complicated compared to Superb II, additional blocks appeared, and some chains began to be duplicated. If you are faced with a non-working cigarette lighter, glitchy climate control, or the on-board computer suddenly turning off, most likely the problem lies in the fuse. But before you climb into the block with a screwdriver, it’s worth understanding which element is responsible for the problem node and how to diagnose it correctly.

Where are the fuse boxes in the ŠKODA Superb?

B ŠKODA Superb (especially in the third generation) fuses are distributed across three main blocks, plus there are additional fusible links under the hood. Their location depends on the year of manufacture and configuration, but the general layout remains the same:

• 🔧 Main unit in the cabin - to the left of the steering column, behind the plastic cover. ~80% of all fuses are concentrated here, including those responsible for multimedia, lighting and comfort systems.
• 🚗 Block under the hood - next to the battery (in Superb III it is often hidden under a plastic cover). Contains high-amp fuses for starter, alternator and ignition circuits.
• 🔌 Additional unit in the trunk — relevant for versions with a panoramic roof, adaptive cruise control or premium audio system Canton. There may be fuses for the rear parking sensors or the audio amplifier.

B Superb II (3T) the circuit is simpler: the main unit is located under the glove compartment, and under the hood there are only fusible links. But in Superb III (especially after the 2019 facelift), the manufacturer moved some of the fuses to the trunk, which often confuses owners. For example, fuse F37 (responsible for heating the rear seats) was located in the cabin in pre-Restyle, and in the luggage compartment in Restyle.

Explanation of fuses for ŠKODA Superb III (B8, FL): table

Below is the current diagram for Superb III (including restyled versions). Please note: fuse numbers may vary depending on the configuration! For example, in basic Ambition fuse F29 (audio system) may be absent if the car is not equipped with premium acoustics.

Fuse number	Amperage (A)	What is he responsible for?	Notes
F5	10	Low beam (left headlight)	Paired with F6 (right headlight). If burnt out, also check the relay J347.
F17	15	Cigarette lighter, 12V socket in trunk	It often fails when using powerful devices (for example, car vacuum cleaners).
F24	20	Electric folding mirrors	If the mirrors do not fold, also check the fuse F42 (comfort control unit).
F37	30	Heated rear seats	In the 2019+ facelift, it was moved to a block in the trunk. Works only when the ignition is on.
F63	7.5	Kan-bus, engine control unit	Replacing this fuse while the engine is running may cause errors in the ECU!

A complete diagram for your configuration can be found in instruction manual (section “Electrical equipment”) or on the inside of the fuse box cover. However, there is often no data on additional fusesinstalled by the dealer. For example, in cars with factory gas equipment (Lovato or BRC) a separate fuse box is added under the hood.

How to check the fuse in a ŠKODA Superb: step-by-step instructions

Diagnosing a fuse is a simple task, but requires care. Main rule: never test a fuse for a sparkby connecting it directly to the battery. This may cause a short circuit and damage the fuse box.

Use a multimeter in continuity mode|Visually inspect the thread for a break|Check the fuse only with the ignition off|Compare with a known-good fuse of the same rating

-->

Verification algorithm:

1. Turn off the ignition and remove the negative terminal from the battery (especially important for fuses associated with the ECU).
2. Remove the fuse using special plastic tweezers (included with the machine). If you don't have tweezers, use small pliers, but not metal objects that could short the contacts.
3. Inspect the fuse under the light: the burned out thread will be visible as a break. If in doubt, use a multimeter:

   Set the dialing mode (diode icon)
   Touch the probes to both legs of the fuse
   A beep means the fuse is good

4. If the fuse is blown, don't rush to change it. First, find the cause of the short circuit (for example, a bare wire or a faulty relay).

⚠️ Attention: B Superb III fuses F63 (Kan-shina) and F72 (Transmission ECU) are sensitive to static electricity. Touch them only with a grounded tool or wearing gloves.

Common mistakes when replacing fuses (and how to avoid them)

Even experienced car owners sometimes make mistakes that lead to repeated failure of fuses or damage to electronics. Here are the most common mistakes:

• ⚡ Installing a larger fuse. For example, instead of 15A they put 20A, thinking that “it’s more reliable.” This leads to overheating of the wiring and the risk of fire. The denomination must strictly correspond to the diagram!
• 🔄 Ignoring the cause of burnout. If the new fuse blows immediately after installation, there is a short circuit in the circuit. It is necessary to check the wiring, connectors and consumers (for example, a stove motor or radiator fan).
• 🛠️ Using bugs. Inserting wire or foil instead of a fuse is a surefire way to burn the control unit or even the entire car. B Superb with its complex electronics this is especially dangerous.
• 🔍 Block Confusion. For example, the cigarette lighter fuse (F17) is often confused with the trunk socket fuse (F52), although they are of different ratings (15A and 20A, respectively).

Another typical problem is contact oxidation in the fuse block. B Superb II this often leads to “floating” faults (for example, window regulators periodically fail). The solution is to clean the contacts with a special liquid (for example, Kontakt 60) and applying conductive lubricant.

What should I do if the fuse blows again?

If the fuse blows again after replacing, follow these steps:

1. Turn off all consumers in this circuit (for example, if it is a cigarette lighter fuse, unplug all devices from the outlet).

2. Check the wiring for short circuit: inspect the insulation, connectors and inflection places. V Superb Pay special attention to harnesses under the seats and in doorways - there the wires are often rubbed.

3. If visually everything is normal, use the exclusion method: turn off the consumers one by one until you find the culprit. For example, in a safety circuit F24 (mirror) the problem may be in the folding motor or heating.

4. In difficult cases (for example, a short circuit in a CAN bus circuit), contact an auto electrician with a diagnostic scanner. VCDS (VASE).

Where to buy fuses for ŠKODA Superb: original vs analogues

Fuses for ŠKODA Superb sold in three versions:

• 🔹 Original (VAG) - come in a branded packaging with a logo ŠKODA or Volkswagen. Numbers to order: N 017 753 2 (set of mini fuses), N 908 132 01 (set of maxi fuses). Plus: guaranteed quality and exact compliance with denominations. Cons: the price is 2-3 times higher than analogues.
• 🔹 Premium analogues — brands HELLA, BOSCH, Littelfuse. In terms of quality, they are not inferior to the original, but cheaper by 30-40%. For example, setup Littelfuse FKM will cost ~300 rubles against ~800 for the original.
• 🔹 Budget analogues — SAT, ERA, unnamed Chinese sets. Risk of getting married or not being in the denomination. V Superb With its sensitive electronics, such fuses can cause problems (for example, false positives or overheating of contacts).

Where to buy:

• 🛒 Official dealers The most reliable, but also the most expensive option. It is suitable if you need an original safety lock with a guarantee.
• 🛒 Specialty stores (for example, AutoSpetsCenter, Exist) - a wide range of analogues, often available.
• 🛒 Online platforms (Wildberries, Ozon, AliExpress) is cheaper but there is a high risk of forgery. When buying, check the reviews and rating of the seller.

⚠️ Attention: B Superb III with the system KESSY (keyless access) the use of poor-quality fuses can lead to failures in the immobilizer. If after replacing the fuse, the car stopped "seeing" the key, check the fuse. F47 (10A) and reset the errors through VCDS.

💡

For critical circuits (ECU, CAN bus, ignition system) use only original fuses or analogues from HELLA / Bosch. Savings here can turn into expensive repairs.

Frequently asked questions about ŠKODA Superb fuses

The lighter fuse burns immediately after replacement. What's the reason?

Most likely reasons:

1. Short circuit in the 12V socket (for example, due to hitting a metal object or damage to the contacts). Disassemble the connector and check for foreign particles.
2. Failure of the connected device (for example, a DVR or compressor). Try connecting another device - if the fuse does not burn, the problem is in the first one.
3. Wiring damage from the lighter to the fuse block. V Superb III The wire is often rubbed under the center console.

If the problem persists, check the chain with a multimeter in resistance measurement mode (there should be infinity when consumers are disconnected).

Can I use fuses from other brands (for example, from VW Passat)?

Yes, ŠKODA Superb (especially in the third generation) built on the platform. VW MQB, so the fuses Passat B8, Audi A4 B9 or VW Arteon They are fully compatible in terms of size and denominations. The main thing is to check amperity and type (mini or maxi) For example, passing beam safety lock (F5/F6) in Superb and Passat It is the 10A type of mini blade.

What is the fuse responsible for the Superb III tape?

In most configurations, the fuse is responsible for the audio system F29 (15A). However:

• If the car is equipped with a system Canton or Dynaudio, the safety lock is added F58 (20A) for the amplifier.
• In versions with MIB2/MIB3 (Touch screen) also check the fuse F60 (10A) responsible for the display.

If after replacing the fuse the head unit does not turn on, check the relay J317 (in the main unit) and reset the errors through the diagnostic connector.

Where is the fuse on the starter in Superb II?

B Superb II (3T) The starter safety lock is fuse link S10 (110A), located in a block under the hood (near the battery). It looks like a thick black rectangle with metal contacts. To replace:

1. Remove the negative terminal from the battery.
2. Unscrew the fastening of the fuse block (torx T20).
3. Remove the insert with a special removable (goes complete with the car).

⚠️ Important: Never replace this insert with a “bug” – this can cause the wiring to burn!

Why does Superb III have a seat heating fuse?

This problem is typical for restyled versions (2019+). Reasons:

• 🔥 Circuit overload If both seats are on at maximum, the total current exceeds 30A (fuse nominal) F37). Solution: Do not turn on the heating at the same time at full capacity.
• 🧵 Wear of heating elements Over time, they begin to “short.” Check the resistance of the elements (should be ~1-2 ohms).
• 💧 Moisture ingress If there was a leak under the seat (for example, due to clogged air conditioner drainage), this can cause a short circuit.

The solution is to set the fuse on 35A, but this is the not recommended on a permanent basis. The optimal way is to diagnose the chain and eliminate the cause.
