Renault Sandero Fuses: Complete Guide by Year and Engine

Artigo atualizado em 7 de August de 2026 por João Daniel

Where is the fuse box located in the Sandero, what does each fuse protect, and how to identify a blown fuse — separated by generation (2007 to 2024) and by engine (1.0, 1.6, SCe and RS).

What you will find in this guide

Before getting into the technical details, a quick summary for those in a hurry.

• The Sandero had Two generations sold in Brazil. between 2007 and 2024, each with its own fuse box and numbering.
• They exist two fuse boxesOne in the passenger compartment (next to the pedal, under the dashboard) and another in the engine compartment.
• THE The amperage of each circuit changes according to the motor. The 1.0, 1.6 8V/16V, 1.6 SCe, and 2.0 RS engines do not necessarily use the same values.
• The exact numbering of each position is always printed on the lid of the box itself This is the most reliable source available for your specific car.
• Below you will find tables by generation/engine, a list of symptoms x likely fuse, and a step-by-step guide to safely replacing a fuse.

Why isn’t there “one” fuse diagram for the Sandero?

If you came to this article looking for a single diagram that applies to “the Sandero,” the first thing you need to know is that it doesn’t exist. The Renault Sandero was sold in Brazil for almost two decades, between 2007 and the discontinuation of the Stepway version in 2024/2025, going through two complete generations, a mid-life restyling in each of them, and at least four different engine families (1.0 16V Hi-Flex, 1.6 16V/8V Hi-Flex, 1.0 SCe 12V, 1.6 SCe 16V and the 2.0 16V of the RS). Outside of Brazil, the story branches out even further, with the third generation (sold by Dacia in Europe and by other Renault networks in markets such as Colombia, Argentina, Morocco and Eastern Europe) bringing TCe turbo and dCi diesel engines that never arrived here. The Renault Sandero was sold in Brazil for almost two decades, between 2007 and the discontinuation of the Stepway version in 2024/2025, going through two complete generations, a mid-life restyling in each of them, and at least four different engine families (1.0 16V Hi-Flex, 1.6 16V/8V Hi-Flex, 1.0 SCe 12V, 1.6 SCe 16V and the 2.0 16V from the RS). Outside of Brazil, the story branches out even further, with the third generation (sold by Dacia in Europe and by other Renault networks in markets such as Colombia, Argentina, Morocco and Eastern Europe) bringing TCe turbo and dCi diesel engines that never arrived here.

Each of these combinations of body style, year of manufacture, and engine has its own electrical control unit, its own fuse box (sometimes two: one in the passenger compartment and another in the engine compartment), and its own circuit numbering. A fuse that protects the electric window in a 2010 Sandero may be in a completely different position in a 2018 Sandero, even if the function is identical. This happens because Renault revises the wiring harness and the multiplexed control unit (UCH) throughout the model’s life, and because the São José dos Pinhais factory adapted the car to Brazilian realities (ethanol, roads, local options).

Therefore, this guide was organized differently than you usually find: instead of pretending there’s a universal map, it separates the Sandero by generation and engine type, he explains. What each fuse family protectsshows typical amperage ranges for each circuit and teaches you to Read the label on your own fuse box correctly. — which is, ultimately, the most reliable source available, because it was printed specifically for your car’s chassis.

Where is the fuse box located on a Renault Sandero?

Regardless of the generation, the Sandero follows a logic of electrical protection on two fronts:

1. Passenger compartment fuse box. It is located behind a plastic cover on the left end of the dashboard, near the driver’s door, above the clutch/brake pedal. It houses the low and medium current circuits: interior lighting, radio, power windows, locks, horn, windshield wipers, ventilation, 12V socket, and dashboard instruments.

2. Engine compartment fuse and relay box. It’s located in the engine compartment, usually near the battery or firewall, protected by a larger cover. Here you’ll find the high-current fuses and power relays: fuel pump, electronic fuel injection (ECU), radiator fan, air conditioning, headlights (in some years), and the “master” fuse that powers a large part of the electrical system.

This division into two boxes is standard throughout virtually the entire life of the Sandero in Brazil, from the first to the second generation. What changes from one year to the next is… How many fuses fit in each box?, the order/numbering and, in some cases, the exact amperage from the same circuit — especially when the engine changes (a 1.6 16V with four fuel injectors draws more current from the ECU than a 1.0 16V, for example).

Before replacing a fuse in a Sandero: tools and precautions

Replacing a fuse is one of the simplest maintenance tasks there is, but some precautions can prevent headaches (and, in extreme cases, fires):

• Turn off the ignition. And if you’re going to work on the engine compartment, wait for the engine to cool down.
• Use the plastic extractor (that pincer-shaped piece) that fits into the fuse box cover itself — almost every Sandero comes with one from the factory.
• Never replace a fuse with one of a higher amperage. The fuse is designed to blow before the wire; installing one with a higher amperage can melt the wiring harness and cause a fire.
• If a new fuse blows immediately, Don’t insist on exchanging it for another one.There is a real short circuit or overload in the circuit, and the car needs to go to an automotive electrician.
• Fuses related to Airbag, seatbelt pretensioner, and ABS/ESP. These require extra attention — problems in these circuits deserve professional diagnosis, not just a fuse replacement.
• The numbering and colors of fuses follow a universal standard by amperage (this nothing changes between generations):

Keeping this color code chart is useful because, even if the circuit numbering changes from year to year, the color always indicates the correct amperage when replacing a fuse.

Sandero I fuses (2007 to 2014) — First Generation

Launched in December 2007 as Renault’s first global car produced in Brazil, the Sandero I was built on the B0 platform, shared with the Logan. It underwent a restyling in 2011 (more robust bumpers, darkened headlight and taillight masks) without significantly altering the electrical architecture.

Note about the Sandero I: Because it’s an older model, it’s common to find units with informal electrical repairs (spliced ​​wiring, accessories installed outside of factory specifications, such as sound systems and alarms). In these situations, the numbering printed in the manual may not match the actual vehicle in front of you 100% — always visually confirm before blindly trusting the table.

Sandero II Fuses (2014 to 2024) — Second Generation

The second generation arrived in June 2014, based on an updated version of the B0 platform, now sharing the front design with the Logan. This generation had a long lifespan and can be divided into three relevant electric phases.

Phase 1 (2014–2016): 1.0 16V Hi-Power and 1.6 8V Hi-Power

The launch brought revised engines: a 1.0 16V Hi-Power (up to 80 hp) and a 1.6 8V Hi-Power (up to 106 hp), with front airbags and ABS as standard across the entire line, as required by law. In September 2014, the EasyR automated transmission arrived.

Phase 2 (2016–2019): arrival of SCe engines

In November 2016, the SCe (Simple Combustion and fuel economy) family partially replaced the previous one: the 1.0 SCe 12V three-cylinder (up to 82 hp) and the 1.6 SCe 16V four-cylinder (up to 118 hp). These engines use a more modern, multiplexed injection architecture, which usually means… ECU fuses with different amperages from previous Hi-Power engines, plus an additional relay for the electronic throttle control.

In December 2015, it premiered worldwide. Sandero RSThe RS is a sporty version with a 2.0 16V engine producing up to 150 hp, developed by Renault Sport. Due to its more robust injection system (more injectors, individual coils, and potentially more complex torque management), the RS has higher amperage fuses in the engine compartment and, in some cases, an extra fuse dedicated to the sports management system.

Phase 3 (2019–2024): restyling and CVT transmission

In July 2019, the aesthetic update arrived (new front bumper, redesigned rear hatch with LED taillights) and, mechanically, the 1.6 versions began to feature the X-Tronic CVT automatic transmission, of Nissan/Alliance origin. The arrival of the CVT normally implies a proprietary electronic transmission module, with dedicated fuse and relay that are not present in versions with manual or EasyR transmissions.

Engine housing – Sandero II (reference, by engine type)

Why does the engine influence so much? Engines with more cylinders or more fuel injectors (the 1.6 SCe 16V four-cylinder versus the 1.0 SCe three-cylinder, for example) demand more simultaneous current from the injection control unit, so Renault commonly uses a fuse with the next highest amperage in this circuit, even while maintaining the same physical position in the gearbox. The RS, on the other hand, due to its electronic torque management and a more sophisticated exhaust/injection system, tends to have the highest amperage reserve among all Sandero versions sold in Brazil.

Sandero III fuses — international versions (not sold in Brazil)

Renault decided not to bring the third generation Sandero to Brazil, keeping only the second-generation Stepway in production until 2024/2025, when the Renault Kardian will take over. Even so, for those who imported the vehicle, live in another country, or own the version sold by Dacia in Europe (and through Renault networks in Argentina, Colombia, Morocco, and parts of Eastern Europe), a quick overview is worthwhile:

If that’s your case, Do not use tables from previous generations as a reference.The third generation runs on a completely new CMF platform (shared with the Renault Kardian), with a different multiplexed power unit and its own fuse box layout. The owner’s manual specific to your market is essential here.

Sandero fuse blown: common symptoms and likely circuit

A quick diagnostic chart, valid for any generation — the goal is to give you a clue as to where to start, not to replace the label on your box:

Step-by-step guide to locating and replacing a fuse.

1. Turn off the vehicle. and remove the key (or press the start button twice without pressing the brake, in versions with a Card).
2. Open the lid of the corresponding box. — compartment for internal components, motor for high-current components.
3. Locate the printed diagram. On the inside of the trunk lid itself. That’s where your car’s official serial number is located, not on any website.
4. Identify the circuit number. related to the problem (use the symptom table above as a starting point).
5. Remove the suspect fuse using the plastic puller. And check the inner filament: if it’s broken, it’s burned out.
6. Replace with another of the same amperage and color. — never superior.
7. Test the circuit. If the new fuse blows again, stop and call an automotive electrician: there is a real overload in the system.

Frequently Asked Questions

Are the fuses in the Sandero 1.0 and 1.6 interchangeable? Physically, yes (the fuse format is universal), but the recommended amperage for each circuit may change depending on the motor, as shown in the tables above. Always replace it respecting the original amperage for that specific position, and not the “generic” amperage of another motor.

Why does my 2018 Sandero have a different fuse box than the one in the manual I found online for a 2015 model? Because Renault revises the wiring harness and multiplexed control unit throughout production, even within the same generation — especially when a new engine (like the SCe) is introduced mid-life cycle, as happened in 2016.

Is there a separate fuse for the hazard lights and turn signals? In most versions, the hazard lights and turn signals share the same relay/fuse, but in some newer configurations with a multiplexed control unit, this control is done by software within the CHU (Capacity Control Unit), without a traditional dedicated fuse.

Can I use a glass fuse that I bought separately, that isn’t a genuine Renault part? Yes, automotive fuses follow international standards (mini, standard, or maxi), and the brand does not affect safety, as long as the amperage and shape are identical to the originals.

Where is the fuse box located in a Renault Sandero? There are two: one in the passenger compartment, behind a plastic cover on the left side of the dashboard (near the pedal), and another in the engine compartment, near the battery or firewall.

How many fuses does a Renault Sandero have? The number varies by generation and version, but it usually ranges between 25 and 40 fuses, including both boxes (passenger compartment and engine), not counting the relays. The exact count is always on the label on your car’s fuse box cover.

Conclusion

The Renault Sandero’s fuse system is essentially simple and well-divided between the passenger compartment and the engine compartment — but the variety of generations, restylings, and engines the model has received over almost twenty years in Brazil means there isn’t a single map valid for all years. The safest way to work is to use this guide as a general guide to circuits and amperage ranges, but always check the label printed on the fuse box cover of your own car — it was made specifically for the chassis and engine of the vehicle you have, and is the only 100% reliable source when it comes to exact numbering.
