Fuse box ŠKODA Octavia Tour: location, diagram and replacement

Fuse box in ŠKODA Octavia Tour - This is a critical component on which the operation of the vehicle’s electrical equipment depends. A faulty fuse can cause the headlights, power windows, audio system, or even the engine to fail. However, many owners encounter difficulties when finding a block, deciphering a circuit, or replacing elements. In this article we will look at all generations of Octavia Tour (A5, A7, FL), show exact locations blocks, we will give a detailed explanation of fuses and relays, and also explain how to check and change them correctly without risk to the electronics.

Feature Octavia Tour — the presence of several fuse boxes at once: the main one in the cabin, an additional one under the hood and sometimes a third one in the trunk (depending on the configuration). We have collected current diagrams for all modifications, including diesel and gasoline versions, as well as hybrid models. If you notice that some device has stopped working, but the light on the panel does not light up - check the fuses first. This will save time and money on diagnostics at the service center.

Where is the fuse box in the ŠKODA Octavia Tour?

B Octavia Tour The fuse blocks are located in three zones, but their number depends on the year of manufacture and configuration. Main places:

• 🚗 Salon block - to the left of the steering column, behind the plastic cover (the most popular, responsible for 80% of the electronics).
• 🔧 Engine compartment block — next to the battery (usually on the right), covered with a black cover with latches.
• 📦 Luggage block - only in versions with extended electronics (for example, Octavia Tour RS or Scout), located under the trunk floor.

In models Octavia Tour A5 (2004–2013) the interior unit is often hidden behind the glove compartment - to get to it, you need to remove the side panel. B Octavia Tour A7 (2013–2020) and restyled FL (2017–2023) access is simplified: just pull the bottom of the cover near the pedals. The engine compartment is located in approximately the same place in all generations, but in diesel versions (1.6 TDI, 2.0 TDI) can be additionally protected by a rubber cover.

Important: in hybrid Octavia Tour iV (from 2020) a separate block for the high-voltage system has been added - touching it without preparation is dangerous! It is marked with a yellow label with a lightning bolt and is located under the rear seat.

Fuse diagram and decoding: what is responsible for what?

Each fuse in Octavia Tour marked with number and ampere (for example, F32 10A). Below is the current table for salon unit (most in demand). For accuracy, we indicate the differences between generations:

Number	A5 (2004–2013)	A7/FL (2013–2023)	Purpose	Amperity
F5	Low beam (left)	Low beam (left) + DRL	Headlights, dimensions	10A
F17	Cigarette lighter	Cigarette lighter + USB port	12V sockets	20A
F30	Window lifters	Power windows + mirrors	Electrical package	30A
F42	Audio system	Audio system + navigation	Multimedia	15A
F63	—	Parking sensors	Parktronic	10A

B Octavia Tour A5 fuse F25 (15A) is responsible for heated seats, and in A7/FL is responsible for this F29 (20A). Diesel versions have a fuse added F58 (10A) for glow plugs. If you have Octavia Tour Scout or RS, check the block in the trunk - there may be fuses for all-wheel drive (Haldex) or sports suspension.

Attention: in hybrid Octavia Tour iV, fuse F70 (50A) is responsible for the connection between high-voltage and low-voltage systems - replacing it requires disconnecting the battery and resetting errors through diagnostics!

How to check a fuse without a tester?

If you don’t have a multimeter at hand, you can visually inspect the fuse in the light - a blown fuse will have a broken thread inside. You can also replace a suspicious fuse with a known working fuse of the same rating (for example, from the cigarette lighter circuit).

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

Replacing the fuse in Octavia Tour It takes no more than 5 minutes, but there are nuances that will help you avoid mistakes:

1. Turn off the ignition and remove the key from the lock. In hybrid versions, additionally turn off the high voltage system (button under the rear seat).
2. Remove the fuse box cover - on A5 you will need to unclip 2 clamps to A7/FL Just pull the notch on the bottom.
3. Find the faulty fuse according to the diagram (see section above) and remove it plastic tweezers (usually attached to the block cover).
4. Install a new fuse same denomination. Using a high ampere fuse may result in a wiring fire!

If after replacement the fuse blows again, this indicates short circuit in the chain. In this case, you need to check the wiring for damage or contact service. For example, in Octavia Tour with 1.8 TSI A common problem is chafing of the harness wires near the pedal assembly - this leads to constant burnout F30 (30A).

Turn off the ignition and remove the key

Wear gloves (optional but recommended)

Prepare a new fuse of the required rating

Check for moisture in the block

⚠️ Attention: Never use "bugs" (homemade jumpers made of foil or wire) instead of fuses! B Octavia Tour this often leads to a fire in the comfort control unit (BCM), the cost of repairs exceeds 50,000 rubles.

Typical fuse problems in Octavia Tour

Owners Octavia Tour often encounter repeated faults related to fuses. Here are the most common:

• 🔥 Burnout F17 (20A) - the cigarette lighter into which powerful devices are connected (for example, a compressor or inverter) is usually to blame. B A7/FL This fuse also protects USB ports.
• 💡 Constant burnout F5/F6 (10A) — the problem is in the low beam lamps or oxidation of the contacts in the headlight unit. In diesel versions it may be due to DRL (daytime running lights).
• 🚪 Power window failure (F30 30A) - often caused by moisture getting into the door motors or jamming of the mechanism. B Octavia Tour Scout this may be due to the additional load from heating the mirrors.
• 🎵 The radio does not work (F42 15A) — check the circuit for a short circuit, especially if a non-standard audio system was installed.

B Octavia Tour 1.4 TSI (especially before 2016) there is a known problem with the fuse F23 (10A)responsible for oil pressure sensor. Its burnout leads to a false activation of the emergency lamp on the panel. The solution is to replace the sensor and check the wiring near the oil filter.

If your car's fuses frequently blow for no apparent reason, check:

• Battery condition (low voltage can cause current surges).
• Corrosion on the fuse box terminals (especially in A5 after 10 years of operation).
• Non-standard equipment (alarm systems, DVRs) connected directly to the wiring.

How to check a fuse with a multimeter?

To accurately diagnose the fuse in Octavia Tour It's better to use a multimeter. Here's how to do it:

1. Put the multimeter into test mode resistance (Ω) or calls.
2. Touch the probes to the fuse contacts. The working one will show 0 Ω (or will emit a beep in the dialing mode).
3. If on the screen 1 or OL - the fuse has blown.

You can also check voltage in the block socket:

1. Turn on the ignition.
2. Connect the black probe of the multimeter to ground (for example, to a metal part of the body).
3. Use the red probe to touch one of the fuse socket contacts. If there is voltage (approx. 12V), and the device does not work - the fuse has blown.

B Octavia Tour with the system Start-Stop (for example, 1.0 TSI or 1.6 TDI) When checking fuses with a multimeter, the on-board network protection may be triggered. In this case, turn off the system using the button on the center console before taking measurements.

What should I do if the fuse blows again?

If after replacing the fuse in Octavia Tour burns out again, this means that there is short circuit or increased load. Follow the algorithm:

1. Disable all consumers in the circuit (for example, if the light is on F17, remove all devices from the cigarette lighter).
2. Check wiring for damage. B Octavia Tour A5 The wires under the pedal assembly often fray, in A7 - in the corrugation near the driver's door.
3. Use a tester to find a short circuit:

   1. Turn off the fuse.
   2. Connect a multimeter in ammeter mode (10A) between the socket contacts.
   3. If there is current (readings above 0) - there is a short circuit in the circuit.

4. If the problem is not found, check consumers separately (for example, window motors or headlight bulbs).

B Octavia Tour with DSG-7 fuse blown again F48 (10A) (responsible for the box selector) may indicate a malfunction mechatronics or lever position sensor. In this case, computer diagnostics is required.

⚠️ Attention: In hybrid Octavia Tour iV repeated blowing of fuses in the high-voltage unit (F70–F75) may prevent the vehicle from starting. Self-repair is not allowed here - you need a tow truck and contact an official dealer.

Where to buy fuses for Octavia Tour?

Fuses for ŠKODA Octavia Tour sold in three versions:

• 🛒 Original - art. N 908 132 01 (set of 10 pieces of different denominations), cost ~500 rubles. Sold from official dealers or online stores (for example, Exist.ru, Autodoc).
• 🔧 Analogs — brands Bosch, Hella, Valeo. The quality is not inferior to the original, but the price is lower (set ~300 rubles).
• 💰 Universal - sold in any auto store (for example, ATP), but the quality may be worse. For critical circuits (for example, ECU) it is better to use the original.

For Octavia Tour A5 fuses will fit mini-blade (standard), and for A7/FL used in some circuits micro-blade (smaller size). Check the type according to the diagram on the block cover! In diesel versions, fuses for glow plugs (F58) often come complete with relays - it is better to buy them in pairs.

If you need to replace relay (eg cooling fan relay J317), take the original art. 4D0 951 253 or equivalent from Hella (art. 4RA 003 563-121). B Octavia Tour RS fuel pump relay (J17) often fails due to increased load - it is better to keep it in reserve.

FAQ: Frequently asked questions about fuses in Octavia Tour

Can I use a higher rated fuse if I don't have the correct one on hand?

No! This may cause a fire. For example, if instead F17 (20A) put 25AIf there is a short circuit in the cigarette lighter, the wiring will melt. As a last resort, temporarily use a fuse less denomination (for example, 15A instead of 20A), but replace it with the correct one as soon as possible.

Why is there no fuse F63 (parking sensors) in my Octavia Tour A7, although it is in the diagram?

This means that your car is not equipped with parking sensors from the factory. There may be a plug or an empty slot in the block. If you installed the parking sensors yourself, check whether it is connected directly to another fuse (for example, F42 for the radio).

How to remove the fuse box cover in Octavia Tour A5 if the latches are broken?

B A5 The lid is attached to two plastic latches, which break over time. To remove it without damage, carefully pry it from the side (from the door) with a screwdriver and pull it up. If the latches are already broken, the cover can be fixed with double-sided tape or replaced with a new one (art. 1Z2 937 501).

What should I do if, after replacing the fuse, the device still does not work?

Possible reasons:

1. The device itself (for example, a lamp or motor) is faulty.
2. The problem is in the relay (check for a click when turned on).
3. Broken wiring or oxidation of contacts in connectors.
4. Control unit malfunction (e.g. BCM or ECU).

Start by checking the relays (they are located next to the fuses) and visually inspecting the wiring.

Is it possible to wash the fuse box if water gets into it?

Yes, but carefully! Disconnect the battery, remove the unit and wash isopropyl alcohol (not water!). Dry with a hairdryer (cold air) or leave in a dry place for 24 hours. Do not use compressed air - it may damage the contacts. After drying, check all fuses and relays for corrosion.
