Car owners Skoda Superb First generation often face the need to check the electrical system in case of problems with lighting, windows or tape. The main element controlling the supply of current to the various nodes of the machine is fuse box. Unlike more modern models, in Skoda Superb 1 (produced from 2001 to 2008) distribution modules have their own design and location, which is important to know every car owner.
The electrical circuit of this car is quite complex, and failure of one element can lead to the failure of a number of functions. If you find that you have stopped working cigarette lighter or not included window liftersFirst of all, you need to check the safety locks. Incorrect diagnosis can lead to replacement of working parts or, worse, to re-burning of the fuse due to a hidden short circuit in the wiring.
Location of the main protection modules
In the car Skoda Superb 1 There are not one, but several blocks that are responsible for protecting the electric circuits. The main module is located in the cabin, hidden behind a decorative cover on the dashboard from the driver's side. To access it, you need to open the driver's door and snap the plastic plug. Inside you'll see a compact one. fuse box with a diagram applied to the lid, which helps to quickly identify the desired element.
The second important unit is located in the engine compartment. This unit is responsible for high-current circuits, such as generator, cooling system and headlights. It is in a black plastic case next to the battery. It is important to note that some relays are also placed here, not in the cabin. When checking the electrician under the hood, special care should be taken because of the proximity to the working engine units.
Depending on the year of release and configuration, the location of some relays may vary slightly. In later versions Skoda Superb (Restyled in 2005) the scheme has become a bit more complicated. Always check the current instructions for your specific modification. Relay and fuses can be rearranged in places if the owner made independent modifications of the wiring.
Diagram and decoding of interior fuses
Each safety lock in the cabin has its own number and nominal value, indicated by color and number on the body. Standard values range from 5 to 30 amps. For ease of troubleshooting manufacturers apply color coding: yellow - 5 A, brown - 7.5 A, red - 10 A, blue - 15 A, green - 20 A. Understanding this color system allows you to quickly assess what current a particular node consumes.
Below is a table with the main functions of fuses located in the cabin of the car Skoda Superb 1. Please note that the numbering may vary depending on the year of issue.
| Fuse number | Denomination (A) | Protected node | Case color |
|---|---|---|---|
| 1 | 5 | Dashboard, relay. | Yellow |
| 3 | 10 | Left headlight (low beam) | Red |
| 7 | 15 | Cigarette lighter, socket | Blue |
| 12 | 20 | Window lifters | Green |
| 24 | 30 | On-board computer | Green |
Special attention should be paid to the fuse number 7, as it often fails due to overload when using powerful car chargers. If you stopped working cigarette lighter- Check him first. Also often burn out elements responsible for work. heated seats and rear view mirrors.
⚠️ Warning: Before removing any fuse, be sure to turn off the ignition of the car. Turning on the power under load can cause sparking and damage to the contacts in the unit.
Fuse box in the engine compartment
Engine compartment Skoda Superb 1 contains a powerful unit that protects power units and security systems. There are safety locks with a higher nominal value, capable of withstanding significant current loads. Access to this block is carried out by snapping the plastic cap locks. Inside you will find not only the smooth inserts, but also massive ones. power relays.
The key elements here are the fuses responsible for the work generator, electric fan cooling lock-lock. If the engine does not start, and the starter does not turn, the problem may not be in the starter itself, but in the burnt-out fuse that supplies power on the relay of the retractor. Checking these elements should be carried out first of all when diagnosing problems with the start.
Sometimes moisture enters the block body under the hood, which leads to oxidation of the contacts and false alarms of the protection. Examine the inside of the lid and the contacts themselves for traces of corrosion or white plaque. If oxidation is detected, the contacts should be carefully cleaned and, if necessary, processed. contact lubricant.

Rules for safe replacement of fuses
The process of replacing a burnt out element seems simple, but requires compliance with certain safety rules and sequence of actions. Never try to replace the safety lock with a higher-value element. This can cause overheating of the wiring and even fire. If the fuse with a nominal value of 15 A is burned out, put only the same one, and not 20 A or 30 A.
To remove the fuse, use special tweezers, which are usually attached to the block cover or located in the car tool kit. If you don’t have tweezers, you can use thin pliers with insulated handles, but you need to act very carefully so as not to damage adjacent contacts. Insert the tweezers into the holes on the fuse housing and gently pull up.
☑️ Preparing to replace the fuse
After removal, carefully inspect the metal jumper inside the plastic case. If it is torn or blackened, the element is faulty. Insert the new fuse until it clicks. Make sure it fits snugly and doesn't wobble. After replacement, turn on the ignition and check the operation of the unit that has stopped functioning.
⚠️ Caution: If the new fuse blows immediately after installation, there is a short circuit in the circuit. In this case, replacing it yourself will not help; you need to contact an auto electrician to find the wiring defect.
What to do if there are no tweezers?
If you don't have special tweezers on hand, you can use a thin bladed screwdriver or eyebrow tweezers, but be extremely careful not to bend the contacts in the block. Do not use metal objects with sharp edges, as they may short circuit the contacts.
Relay diagnostics and testing
In the fuse box Skoda Superb 1 Relays are also installed that control the switching on of powerful current consumers. Relays often fail due to burnt contacts inside the housing. Symptoms of a relay malfunction may be similar to a blown fuse: no clicking sound when turned on, a non-functioning unit with a working fuse.
To check the relay, you can use the method of replacing it with a known-good element from another circuit (if they have the same rating and pinout). For example, if it doesn't work windshield washer, you can swap the washer relay and side light relay. If the problem has moved, then the relay is at fault. You can also use a multimeter to test the coil and contacts.
The location of the relay is often indicated on the block diagram. B Skoda Superb they can be numbered as J-elements. Interlock relay and fuel pump relay have a unique design and require precise replacement.
Before purchasing new parts, take photographs of the locations of all relays and fuses. This will help you quickly restore the circuit in case you accidentally mix them up during diagnostics.
Common causes of burnout and prevention
Constantly blowing fuses in the same place indicates a serious problem in the electrical system. The most common reason is the use of non-standard equipment with high current consumption. Installing powerful subwoofers, additional spotlights or low-quality Chinese chargers often leads to overloading of circuits.
Another reason could be worn wiring. Over time, the insulation of wires in the engine compartment or door panels can fray, causing a short circuit to ground. Particular attention should be paid to the wiring going to door locks and window regulators, since it experiences constant mechanical stress when opening and closing doors.
Regular maintenance includes visual inspection of contacts for oxidation and checking terminal tightness. If you live in an area with high humidity, it is recommended to install additional moisture protection on the fuse box. Corrosion Contacts are a common cause of unstable electronics in older cars.
Regularly checking the condition of the contacts and avoiding the use of non-standard powerful current consumers is the best prevention of problems with the fuse box.
FAQ: Frequently asked questions
Where is the second fuse box located in Skoda Superb 1?
The second unit is located in the engine compartment, next to the battery. It is responsible for powering the power units, cooling system and headlights. Access is through a plastic cover with latches.
What should I do if the fuse blows immediately after replacement?
This indicates a short circuit in the circuit. Do not attempt to replace it with a higher rated fuse. It is necessary to disconnect the consumer and check the wiring for insulation damage or short to ground. It is recommended to consult a specialist.
How to determine the fuse rating if the numbers are erased?
The rating can be determined by the color of the case: yellow - 5 A, brown - 7.5 A, red - 10 A, blue - 15 A, green - 20 A, yellow/clear - 25 A. You can also use a multimeter to measure the resistance if it is not completely burned out.
