Owners Skoda Octavia A7 (2013–2020) often encounter the problem of a non-functioning cigarette lighter - the device does not heat up or supply voltage to charge the phone or DVR. In 90% of cases, the culprit is a burnt-out fuse, which protects the circuit from short circuit. But where to look for it in the fuse block, what is the number of the required element, and how to replace it correctly?

This article will help you understand the intricacies of an electrical circuit. Octavia A7, avoid typical diagnostic mistakes and learn how to change the fuse yourself without contacting a service center. We will take a detailed look at the location of the blocks, markings, and also give advice on choosing spare parts and checking the circuit with a multimeter.

Where is the cigarette lighter fuse located? Skoda Octavia A7

B Octavia A7 (including restyled versions 2017–2020) the cigarette lighter fuse is located in main fuse box, which is located inside the car. Exact location:

  • πŸš— Under the glove compartment on the driver's side β€” the block is hidden behind a plastic cover, which is secured with latches.
  • πŸ”§ To open the cover, pull it towards you from the bottom corner (pedal side).
  • πŸ“Œ The cigarette lighter fuse is marked as F37 (face value 15 A for most trim levels).

Important: in some versions Octavia A7 (for example, with the option Cigarette Lighter Package) a fuse can be installed on 20 A. Check the markings on the unit body or in the instruction manual.

πŸ“Š Where did your cigarette lighter fuse blow?
  • In the main block (F37)
  • In an additional block (if available)
  • I don't know, haven't checked yet
  • I have another problem

If your car has additional cigarette lighter in the trunk (optional for some configurations), its fuse may be located in another block - F60 (also 15 A). Check this in Electrical diagram your modification.

Fuse box diagram: how to find F37

Fuse box Skoda Octavia A7 has a standard layout, but the arrangement of elements may vary slightly depending on the year of manufacture and configuration. Below is the current diagram for most versions:

Fuse number Denomination (A) Purpose Notes
F37 15 Cigarette lighter, 12V socket in center console Main fuse for front cigarette lighter
F60 15 Additional 12V socket (trunk, rear row) Only for vehicles with the option Rear Power Socket
F42 10 Cigarette lighter illumination Responsible only for the light bulb, does not affect the power supply
F50 20 Audio system, USB port Sometimes mistakenly confused with the cigarette lighter fuse

To avoid confusion F37 with neighboring elements, focus on fuse color:

  • 🟠 15 A - orange body.
  • 🟑 20 A β€” yellow (if installed in your configuration).
  • πŸ”΄ 10 A β€” red (for backlighting).
πŸ’‘

If the fuse F37 burns out again after replacement, the problem may be a short circuit in the wiring or a malfunction of the cigarette lighter itself. Check the circuit with a multimeter before installing a new element.

Step-by-step instructions for replacing the fuse

Replacing the cigarette lighter fuse in Skoda Octavia A7 takes no more than 5 minutes, but requires care. Follow the instructions:

  1. Turn off the ignition and make sure all electrical appliances are turned off (including the radio and climate control).
  2. Remove the fuse box cover under the glove compartment, pulling it towards you.
  3. Find the fuse F37 (orange, 15 A) and remove it with special pliers from the kit or tweezers.
  4. Check the fuse for integrity: if the thread inside is burnt out, replace it with a new one with the same rating.
  5. Install a new fuse and make sure it fits tightly into the socket.
  6. Turn on the ignition and check the operation of the cigarette lighter.

Done: 0 / 4

If the cigarette lighter still does not work after replacing, check:

  • πŸ”Œ Contacts in the fuse socket - they may be oxidized or deformed.
  • πŸ”‹ Socket voltage multimeter (should be ~12 V when the ignition is on).
  • πŸ”§ The cigarette lighter itself - sometimes the spiral inside the device burns out.
What should I do if the fuse blows immediately after replacement?

This indicates a short circuit in the circuit. Do not install a fuse of a higher rating (for example, 20 A instead of 15 A) - this may cause a fire! Contact an auto electrician to diagnose the wiring or replace the cigarette lighter with a new one (original part number: 5E0 919 141 B).

How to check a fuse without removing it from the block

It is not always convenient to remove the fuse to check, especially if you do not have a spare one on hand. B Skoda Octavia A7 it is possible to diagnose its integrity without dismantlingusing a multimeter or a simple test light.

Method 1: Multimeter

  1. Set the multimeter to test mode circuit integrity (diode or beep icon).
  2. Connect the probes to the metal contacts of the fuse F37 (without removing it!).
  3. If a beep is heard or resistance is close to 0 ohm - the fuse is OK. If not, it's burned out.

Method 2: Using a test light

  • Take any 12V car light bulb with two wires.
  • Connect one wire to mass (for example, to a metal part of the body).
  • Touch the second wire alternately to the two fuse contacts F37.
  • If the light comes on on both contacts, the fuse is intact. If it’s only on one, it’s burned out.

Before checking, make sure that the ignition is turned on (position ON), otherwise no voltage will be supplied to the fuse and the diagnostics will be incorrect.

Typical mistakes when replacing a fuse

Even something as simple as replacing a fuse can be done incorrectly, leading to further problems. Here are the most common mistakes owners make Skoda Octavia A7:

⚠️ Attention: Never install a fuse with a rating higher than 15 A (for example, 20 A or 25 A) - this may cause the wiring to overheat and cause a fire! If the standard fuse constantly blows, look for the cause in a short circuit rather than increasing its power.
  • ❌ Using "bugs" (homemade wire jumpers) instead of a fuse. This is extremely dangerous and may cause a fire!
  • ❌ Replacing the fuse with the ignition on. Always turn off the power before working on electrical equipment.
  • ❌ Installing the wrong type of fuse. Use only blade fuses standard Mini Blade (not to be confused with Maxi Blade for the battery!).
  • ❌ Ignoring oxidized contacts. If the fuse socket is dirty, the new element may quickly burn out.

Another common mistake is confusion between cigarette lighter and USB port fuses. B Octavia A7 they are different:

  • πŸ”Œ F37 (15 A) - cigarette lighter.
  • πŸ“± F50 (20 A) - USB/aux input (does not affect the cigarette lighter!).

How to choose a quality replacement fuse

The reliability of the cigarette lighter and the safety of the car's electrical system depend on the quality of the fuse. B Skoda Octavia A7 It is recommended to use original spare parts or certified analogues.

Original fuses:

  • πŸ”Ή Article: N 908 132 03 (15 A, orange).
  • πŸ”Ή Manufacturer: VW Group (suitable for all models of the concern, including Skoda, Volkswagen, Audi).
  • πŸ”Ή Average price: ~50–100 rubles per piece.

High-quality analogues:

  • πŸ”Ή Bosch (series Mini Blade, article 1 987 314 115).
  • πŸ”Ή Hella (article 8FL 005 141-811).
  • πŸ”Ή Littelfuse (article 0ATM.15A).
⚠️ Attention: Buy fuses only from trusted stores (for example, Exist.ru, Autodoc, official dealers Skoda). Cheap Chinese analogues often have poor-quality contacts, which leads to repeated burnouts.

Important: in Skoda Octavia A7 since 2017 (facelift), fuses with reinforced contacts are sometimes installed (series Mini Blade Plus). They are visually similar, but have a tighter attachment in the nest. Check with the dealer if the fuse falls out or warms up.

Frequent questions about the lighter safety Octavia A7

Is it possible to drive without a cigarette lighter fuse?

Technically yes, but highly not recommended. Without a fuse, the lighter chain remains unprotected from short circuit, which can lead to a fire. If you urgently need to use a cigarette lighter, temporarily set the fuse at 15 A and as soon as possible eliminate the cause of its burnout.

Why does the fuse blow immediately after replacement?

This indicates short circuit in the chain. Reasons:

  • πŸ”Œ Damaged wiring (furnished wires under the glove compartment).
  • πŸ”₯ Faulty lighting (closing inside the spiral).
  • πŸ’§ The water is then stained (for example, after the stain).

Solution: disconnect the lighter from the wiring and check the chain with a multimeter in mode calls.

Where to buy an original fuse for Octavia A7?
