Problem with a non-working cigarette lighter or 12 volt socket on a car Skoda Superb second generation - this is one of the most common complaints from owners. A sudden power outage to the dash cam, charger or pump can turn a trip into a real headache, especially if you are far from the service.

Model owners Skoda Superb Often faced with a situation where electronics stop receiving power through the center console. The main reason lies in the burnt-out fuse, which protects the circuit from short circuit. However, it's not always just the fuse link; Sometimes the problem may be hidden in the contacts or the connector itself.

To solve the problem yourself, you need to clearly understand the design of your car's electrical system. Skoda Superb The second (torch) has a complex energy distribution scheme, where separate fuse blocks are responsible for different functions. Knowing the exact location and denomination of the desired element, you can restore the efficiency of the cigarette lighter in a matter of minutes.

Location of fuse boxes and their access

By car Skoda Superb The second generation (body 3T) provides several zones of installation of protective elements. To find a burnt-out cigarette lighter fuse, you need to focus on two main places. The first and most likely is a block of fuses hidden behind a removable panel in the end of the dashboard from the driver's side.

To reach this block, open the driverโ€™s door and find a plastic plug on the dashboard end. It is mounted on special latches, so it should be pressed carefully, using a plastic blade or a flat screwdriver, so as not to damage the trim of the cabin. After removing the lid, you will see rows of fuses and relays, each of which is numbered.

The second important unit is in the luggage compartment, but for the cigarette lighter it is used less often. It is located behind the skin of the left or right rack of the trunk, depending on the configuration and year of release. However, in the vast majority of cases, the fault lies in the front block. Pay attention to this. fuse ratingSince the use of a high-current element can cause the wiring to ignite.

Cigarette lighter fuse diagram and identification

Determine the desired element without a schema can be by exclusion, but it is long and inconvenient. It is much more effective to refer to the official documentation or table below. Depending on the year of issue Skoda Superb II and body type (liftback or station wagon) Superb Combi), the fuse number may vary slightly, but the current value usually remains stable.

Most often, a fuse with marking is responsible for the work of the lighter 30A (amperes) It's protected by an orange hull. If you see that the plastic lintel inside the fusible insert is broken or melted, then the element must be replaced immediately. It is important to check whether the adjacent element responsible for the 12B outlet has also burned out, as they are sometimes combined into a single circuit.

Below is a table with basic data for quick search. Please note that in some versions Skoda Superb There may be two separate fuses: one for the lighter, the other for an additional socket in the trunk or armrest.

Fuse number Rated current Case color Purpose
SB19 (or SB20) 30A Orange Cigarette lighter, 12V socket
SB14 15A Blue Lighter (in some configurations)
SB33 40A Yellow Socket control relays
SB5 10A Red ECU of the engine control system (connected circuit)

If you are not sure about the marking, visually inspect all the elements in the block. The floating insert should be whole. If you do not have spare fuses on hand, you can temporarily use a lower-denomination element, but only for a short time to check the performance of the chain. Never install a safety lock with a higher nominal value than it should be in the scheme.This will cause the wires to burn and a possible fire.

Step-by-step instructions for replacing the fuse

The replacement process is extremely simple and does not require special skills or expensive equipment. The main rule is that before starting work, be sure to turn off the ignition and remove the key from the lock. This will eliminate the risk of short circuit when removing the element.

In the fuse block located at the end of the dashboard, you will find a special tweezers that are designed to extract fusible inserts. It is usually fixed on the inside of the block cover or lies next to the block itself. Take tweezers, pinch them the body of the burned fuse and carefully pull it out of the nest.

After extraction, carefully examine the element. If the metal bar inside is torn or traces of soot are visible, the element is faulty. Insert a new fuse with the same face value (usually 30A) before the characteristic click. Make sure it sits tight and doesn't stagger.

If after replacing the fuse, the cigarette lighter worked, the problem is solved. However, if a new element burns instantly, it indicates a short circuit in the circuit. In this case, further attempts at replacement are useless and dangerous. You need to look for the cause of the closure in the wiring or in connected devices.

Diagnostics of socket and cigarette lighter

Sometimes the problem lies not in the fuse, but in the connector itself. During operation, the contact inside the cigarette lighter may weaken, oxidize or deform. If you plug in a device and it doesnโ€™t warm or charge, check the status of the central contact.

A common cause of fuse burnout is the use of poor-quality adapters or devices with high current consumption. For example, cheap inverters or powerful compressors can create a peak load that exceeds the protection face value. Also, the problem occurs if a metal object enters the socket, closing the central contact with the side walls.

To check the efficiency of the outlet itself, you can use a multimeter. Set the device in constant voltage measurement mode and touch the central contact and side wall with probes. When the ignition is turned on, there should be about 12-14 volts. If there is no voltage and the fuse is intact, then the problem is in the wiring or relay.

โš ๏ธ Attention! When checking contacts with a multimeter, be extremely careful. Short circuit of the probes can cause spark and damage to the socket contacts.

If a visual examination shows that the central contact has been omitted or oxidized, it can be gently lifted with a thin screwdriver or tweezers. However, this should be done very delicately so as not to break the plastic part of the connector. Cleaning oxides is better to carry out a special contact spray, not sandpaper.

Common causes of frequent burnout

If the fuse burns out regularly, even after replacing it with a new one, this is a signal of a system malfunction. One of the most common reasons is the use of devices with current consumption above 30 Amps. Many drivers are connected to the lighter. Skoda Superb powerful heaters or vacuum cleaners that create a load close to critical.

Another reason is the violation of the integrity of the insulation of the wiring. In the area of the fuse block or under the plastic dashboard skin, wires can rub against the metal frame of the body. This creates a direct circuit on the mass, which instantly burns the fuse. Carefully inspect the wiring in the block area, especially if the car has gone through serious road bumps or repair work.

It is also worth paying attention to the state of the relay that controls the power supply chain of the socket. The relay may stick or have internal damage, resulting in unstable supply of voltage and surges of current. In some cases, it helps to replace the relay located next to the fuses of the cigarette lighter.

๐Ÿ“Š What do you most often connect to the cigarette lighter?
  • DVR
  • Phone
  • Compressor
  • Heater
  • Other

Do not ignore the quality of the safety lock itself. Cheap analogues may have an inappropriate denomination or poor quality of a fused insert, which leads to their premature failure. Always use original parts or certified counterparts from proven brands.

Additional nuances and tips

Owners Skoda Superb II is sometimes faced with the fact that the lighter is working, but the 12B socket in the trunk or armrest is not. This is because in some configurations, these chains are separated. In this case, you need to look for a separate fuse for each connection point. The scheme of electrical equipment may differ depending on the market.

If you plan to use a lighter to connect a powerful car audio system or amplifier, it is highly recommended to lay a separate power line directly from the battery with the installation of your fuse. Connect such devices through the standard chain of the cigarette lighter prohibited because of the risk of overheating the wiring.

Regular check of the condition of contacts and fuses will help to avoid sudden breakdowns. If you notice that the fuse has started to warm or smell plastic, stop using the device immediately and contact a specialist. Ignoring these signs can lead to serious consequences.

Before buying a new fuse, measure the current strength of your device with a multimeter to make sure that it does not exceed the nominal value of the standard protection (30A).

โš ๏ธ Attention! If you do not have the skills to work with the electrical equipment of the car, entrust the diagnosis and repair to qualified specialists. Errors in connection can cause the engine control unit or multimedia system to fail.

Remember that safety is a priority. Never use paper clips, wire or other items as a temporary fuse. This is a gross violation of operating rules that can cost you a car. Always have a set of spare fuses of different denominations in the glove compartment.

Frequently asked questions and answers

Where exactly is the lighter fuse on the Skoda Superb 2?

The main fuse of the lighter (usually 30A, orange) is located in the block on the end of the dashboard from the driver's side. To access, you need to remove the decorative stub.

What should I do if the new fuse burns out immediately after installation?

This indicates a short circuit in the chain. Check the outlet for foreign objects, inspect the wiring for insulation damage, and make sure the connected device does not create an overload.

Can a fuse with a lower face value (e.g. 20A instead of 30A) be used?

Technically possible, but it is not recommended for long. The device may not start due to lack of current, or the fuse will burn up at peak loads. It is better to find the right element of value.
