Problem with cigarette lighter not working Skoda Octavia A5 - This is a classic situation that many owners of Czech cars face. In most cases, the reason lies not in the connector itself, but in a burnt-out protective element of the circuit. Cigarette lighter fuse is responsible for powering not only the socket, but also additional devices often connected to it, such as navigators or video recorders.
If you find that the outlet has stopped supplying current, do not immediately run to the store for a new part. The first step should be a thorough diagnosis, which includes checking the visual condition of the contacts and searching for the element responsible for the circuit in the mounting block. Octavia A5 has several fuse boxes, and choosing the wrong place to look can waste a lot of your time.
Finding the right element of protection is not difficult if you know the exact markings and location. In this article we will look in detail at where fuse box in the interior of your car, what the circuit looks like and what specific rating is required for the normal operation of the cigarette lighter.
Localization of fuse blocks in the Octavia A5 interior
In the car Skoda Octavia A5 engineers have provided two main locations for placing electrical circuit protection elements. The first is located in the engine compartment, but it is primarily responsible for powerful consumers such as headlights, cooling fan or battery. To find the cigarette lighter fuse, you need to focus on the indoor unit.
The second unit is located in the cabin, directly on the driver's side. To access it, you need to open the side cover of the dashboard. This is usually done by unscrewing one or two screws that are located at the bottom of the panel, or by carefully unsnapping the latches. Be careful not to damage the plastic when removing the cover.
After removing the cover, you will see the unit itself with a transparent or black cover, which is often marked with fuse diagram. This is where the elements responsible for the cigarette lighter, interior lighting and 12 volt socket are located. It is important to understand that the location may vary slightly depending on the year of the vehicle and engine type.
- 🔍 Open the unit cover using a screwdriver or a special key, if included.
- 🔍 Find the decoding of the symbols on the inside of the cover.
- 🔍 Look for a symbol that resembles a rosette or the words "CIG" (Cigarette Lighter).
⚠️ Caution: Before attempting to remove any fuse, be sure to make sure the vehicle's ignition is turned off. Working on a live circuit may result in a short circuit or electric shock.
If there is no diagram on the lid, don't panic. You can find official documentation online by entering your vehicle's VIN, or use the universal table below. However, remember that even the slightest deviation in the configuration can change the purpose of the contacts.
Markings and denominations: how to find the right element
In the fuse box Skoda Octavia A5 elements vary in color and size, which is directly related to their current strength. For the cigarette lighter, a fuse rated for a current of 15 to 20 Amps is usually used. Most often this is a red (15A) or yellow (20A) element. Fuse rating critical for protecting wiring from overheating.
You need to carefully inspect each item using block diagramto determine which one is responsible for your task. Sometimes one fuse can control several devices at the same time. If one element burns out, this may mean that the permissible load has been suddenly exceeded in the circuit.
The table below shows the most common data for the Octavia A5 model, but it may vary depending on the year of manufacture and the market. Use this information as a reference when searching.
| Designation | Denomination (A) | Color | Purpose |
|---|---|---|---|
| S138 | 20 | Yellow | Cigarette lighter, 12V socket |
| S139 | 15 | Red | Cigarette lighter (alternative version) |
| S140 | 30 | Green | Power seats (for comparison) |
| S141 | 10 | Red | Cigarette lighter illumination |
| S142 | 25 | White | Central lock power supply |
Pay special attention to the fact that sometimes it is not the power fuse that burns out, but the element responsible for lighting the socket. This means that you can light a cigarette, but the light in the socket does not light up. Cigarette lighter illumination has its own separate protection element, which often has a lower value.

The process of replacing a blown fuse
Replacing a security element is a procedure that you can perform yourself in a matter of minutes. You will need a special plastic clip, which is usually found in the fuse box, or thin tweezers. Do not try to remove elements with bare hands or metal tools to avoid shorting.
Gently pinch the legs of the blown fuse and smoothly pull it out of the socket. Inspect the clear plastic part of the element: if the metal bridge inside is torn or blackened, then it is really burned out. Visual inspection - the most reliable way to check without using a multimeter.
Insert a new fuse of exactly the same rating as the old one. Under no circumstances try to replace a burnt-out element with a more powerful one, for example, by installing 30 Amps instead of 20. This can lead to melting of the wiring and a car fire. Skoda Octavia A5 has reliable protection, but only if the correct components are used.
☑️ Replacing the fuse
- 🛠 Use only the standard clamp to remove elements.
- 🛠 Check the integrity of the new fuse before installation.
- 🛠 Make sure the new element fits snugly in the socket.
⚠️ Attention: If a new fuse blows immediately after installation, this is a clear sign of a short circuit in the wiring or a malfunction of the cigarette lighter itself. In this case, further replacement of elements is pointless and dangerous. Electrical diagnostics required by a professional.
After installing the new element, check the operation of the cigarette lighter. Insert the cigarette or adapter and wait a few seconds. If the heating element starts to get hot, then the problem is solved. Don't forget to close the block cover and return the dashboard to its original place.
