Changing the fuel filter on Renault Sandero yourself

When to change the filter element

According to the general recommendations of the manufacturer, replacing the fuel filter in Sandero (including the Stepway cross-version) is necessary no later than 120 thousand kilometers. However, this advice applies only to those car owners who use high-quality fuel. If the car is constantly filled with fuel containing impurities, the fuel filter will require replacement after 30-40 thousand kilometers.

The following “symptoms” indicate contamination of this element:

• reduction in engine power;
• the engine began to consume significantly more fuel;
• the engine is unstable;
• As the speed increases, noticeable clicks occur.

In advanced cases, the engine stops starting. This “symptom” indicates that the fuel filter is completely dirty and is not performing its function.

If your car drives normally and then the engine suddenly stalls and then won't start, the fuel pump button may have tripped, cutting off power to the pump and cutting off fuel supply to the engine. Unfortunately, like any sensor, this module can also fail. The first sign of a malfunction is the turning on and off of the fuel supply to the engine.

In this case, the fuel pump will make noise in the same way as it does when it malfunctions. At the same time, while driving, you will notice that the engine speed will float up and down. Be aware that this can damage the engine injectors as well as the automatic transmission because the transmission will not shift gears correctly (it will engage in a gear that does not match the speed of the vehicle).

If the fuel pump kill switch fails, the engine management system records this event in its memory as an error. The fact is that the fuel pressure sensor informs the computer about a decrease in fuel supply pressure, even at insignificant values. The fuel pump switch is powered from the battery to the ignition switch, to the vehicle's computer, and to the fuel pump. If the switch loses communication with one of the systems, the power supply to the fuel pump is cut off.

There are several error codes in the engine control unit associated with the fuel pump turning off. Here are the most common error codes:

P0005, P0006, P0007, P0087, P0230.

Step-by-step instruction

If you decide to replace the fuel filter yourself and did not pay money for this easy thing at a gas station, it will be more convenient for you to carry out this process in a pit or overpass. You also need to know where the object is. In Renault Sandero TF cars, it is located under the vehicle at the bottom of the fuel tank. That's why you need a pit. So let's get started:

1. The first thing you need to do is relieve the pressure in the fuel system. To do this, you need to find the relay on the fuse block that is responsible for the operation of the fuel pump. Next you need to disassemble it. Once this is done, sit in the driver's seat and turn the ignition key, starting the engine. When the engine starts, it should run for a while until it stalls. This will relieve pressure in the system.
2. Now take a previously prepared container to catch leaking fuel and place it under the place where the fuel filter itself is located.

Installation location of the TF under the bottom of the Renault Sandero car

• Next, you need to disconnect the fuel line hoses from the gasoline purification element. They can be attached to the filter using clips or clamps. If the pipes are attached to clamps, they only need to be compressed and then disconnected. If the pipes are secured with clamps, take a Phillips or flat head screwdriver, whichever is needed, and disconnect the pipes.
• Disconnect the fuel line on the other side of the TF in the same way.
• Grab the TF with a rag, lightly pull the pipe and remove the Renault Sandero gasoline cleaning element.
• Now you need to install a new TF instead of the old one. Please note that the arrow on the TF housing must point in the direction of gasoline flow through the system. Therefore, it is best to remember the direction of the arrow before disassembling the old TF. All steps must be repeated in reverse order. Connect the fuel lines to the TF until the clamps are in place or the clamps are loose.

• Don't forget to install the fuel pump fuse, otherwise your Renault Sandero simply won't start.
• Sit behind the wheel and turn the key in the ignition without starting the engine. You need to wait about a minute until the pressure in the system rises.

Having done all this, you need to go on a test trip and evaluate the performance of the TF. Then reach under the car again and visually inspect the fuel filter. This is done to detect possible fuel leaks. If necessary, repeat the operation of connecting the gas pipe fittings until they are securely fastened. If in this case the leaks are not eliminated, it will be necessary to replace the sealing gaskets of the fuel line tips. They are inexpensive and can be found at any car dealership.

If you are not confident in your abilities or have never encountered replacing this system cleaner, then it is best to entrust this task to professionals.

Types of fuel pumps

First, let's look at the types of fuel pumps for diesel cars, since each of them has its own characteristics and typical fuel injection pump malfunctions. So, knowing what type of pump it is, you can better understand the principle of operation and the immediate cause of the breakdown. Regardless of the type of high-pressure pump, you need to understand that the main unit is the so-called plunger pair - a piston (plunger) and a cylinder (bushing).

There are two main types of injection pumps:

• with direct action and mechanical action of the plunger;
• with battery injection.

However, high-pressure fuel pumps are still divided into classes according to their design. In particular:

• In-line. As the name implies, their working sections are arranged in one row, and fuel is supplied to each cylinder in turn.
• Distribution. With such pumps, one section can supply fuel to several different cylinders. Such devices can be single- or double-plunger.
• Multi-sectional. Another name for them is V-shaped or hydraulic accumulators. They are used for highly powerful, but low-speed engines. They are quite rare.

With direct injection fuel pumps, pumping and injection occur simultaneously. The mechanical drive of the plunger is responsible for this. With battery pumps, fuel is supplied in separate cycles, first it enters the pump accumulator, and only then into the injectors. The most modern systems are controlled electronically and are called Common Rail. They work based on information from numerous sensors located in different parts of the car.

Another injection system is a pump injector. In this case, they are combined into one mechanism. This system simplifies pressure control and also increases reliability, because if one injector fails, the engine will continue to operate, albeit with less power.

High-pressure fuel pumps were also invented for gasoline engines. They are used in engines with direct fuel injection. The pump's job is to supply gasoline under high pressure into the cylinders, where the fuel is directly mixed with the air mass, forming a mixture that is ignited by the spark plug.

Proven fuel filter replacement option

Let's connect a new filter bypassing the old one. The main thing here is not to make a mistake and not to confuse the accessories.

Fuel pump module

One fitting is located at the top of the module cover and two at the bottom. She's a shirt. One of the “bottom” fittings is connected to the filter outlet, the other to the return line valve. The latter is in the “glass” below.

The rubber band is the input of the “return” valve.”

Replacing the fuel filter on Renault Logan is not provided. Therefore, a "traversal" is performed:

The reader will tell you whether there are too many difficulties to overcome to do a trivial filter bypass.

The result of all actions

Judge for yourself: there is an “entrance” in the lid and we will need a couple of fittings (at least).

How to relieve pressure in the fuel system

To avoid accidentally taking a gasoline bath, before touching the fuel system, you must first relieve the pressure in it. If you cannot wait 3-4 hours after stopping the car, proceed as follows.

• With the engine stopped, open and latch the hood.

• Remove the wire from the negative battery

• Remove the mounting block cover by pressing the left and right latches
• Pull out the relay located in the pump mounting block (indicated by the arrow in the figure)
• Connect the wire to the negative side of the battery and run the engine until it stops on its own after the remaining fuel has run out.
• Then turn off the ignition and disconnect the fuel lines.

How to replace the fuel filter on a Renault Sandero car and a video with an overview of the required part

After completing the preparatory work stage, you can proceed directly to replacing the filter element. This requires precise execution of the following transitions:

1. Disconnect the fuel lines. If the attachments are attached to the clamps, you need to squeeze them with your fingers and disconnect them. If the pipes are secured with clamps, you will have to use a screwdriver and then again remove the fuel supply pipes. This is done the same way on both sides of the filter.
2. Pull back the clamp securing the fuel filter and remove the faulty unit.

3. Install the new element, focusing on the position of the arrow on its body. Demonstrates the direction of fuel movement in the system.
4. Connect the pipes until the clamps click or tighten the clamp bolts.
5. Replace the fuel pump fuse, turn on the ignition, but do not start the engine. After increasing the pressure in the system (approximately 30-50 seconds), start the internal combustion engine and take it for a test drive.

After completing the simple steps, you should visually verify that there is no fuel leakage from the joints. Only after this can we consider that the replacement of the fuel filter on a Renault Sandero car was carried out efficiently.

If a fuel leak is detected, it is necessary to double-check the reliability of fastening of the pipes and, if necessary, install new gaskets covering the gas pipeline connections.

The following video provides an overview of the gasoline filter element on a Renault Sandero.

DIY replacement

Before replacing a part that has become unusable, you need to find out where the filter component is located. As stated above, to answer this question, you need to decide on the generation of the car and the type of engine installed.

To find the filter, you need to go under the fuel tank. This part is presented in the form of a cylinder, to which tubes with fuel fit. On models manufactured after 2007, the filter is combined with the pump and other components in a separate unit, fixed in the fuel tank on the right front lower part.

What you need to prepare for work

To change the fuel filter, you will need not only a new part, but also a container into which fuel will be drained during the manipulation. It is also recommended to prepare a rag and a set of screwdrivers, including slotted ones.

Preparatory stage

The procedure for preparing for this procedure depends on the version of Renault Sandero. It is recommended to drive first-generation cars onto an overpass or inspection hole, thereby opening access to the filter element. Later versions of the hatchback can be repaired on a flat surface.

You can start replacing after at least three hours have passed since the engine stopped. During this time period, an increased level of pressure inside the fuel line remains.

1. After this you need to do the following:
2. Remove the cushion from the rear seat and open the cover.
3. Start the engine at idle speed and wait until it stalls due to fuel exhaustion.
4. Turn on the starter for 3-4 seconds to reduce pressure.
5. Disconnect the terminal from the negative terminal of the battery.

Upon completion of the described manipulations, it is necessary to place a prepared container under the area where the filter element is located. The above algorithm can also be used in relation to Renault Sandero Stepway.

Step-by-step instruction

Having understood the features and location of the part, you need to figure out how to change the fuel filter to a new one on a Renault Sandero. To do this you will need:

1. Press the fuel line hose clamps and disconnect the pipes. On first generation models, the fastening is made in the form of clamps. In this case, you will have to resort to using a screwdriver.
2. Remove the second fuel line hose located on the other side.
3. Remove the filter from the holding structure and drain the remaining fuel into a container.
4. Install a new filter element.

The last point will be performed in reverse order according to the following algorithm:

1. Secure the part to the clamp and place the fuel line hoses onto the fittings. At this point, the latches should snap into place. If the replacement is carried out on a first generation Renault Sandero, then you need to tighten the bolts on the clamps tightly.
2. Connect the block to which the wires fit to the connector of the block cover with the filter element.
3. Return the negative terminal to its place.
4. Turn the key in the ignition without starting the engine. Thanks to this, pressure is created in the fuel lines necessary for normal fuel supply.

After 2-4 seconds, a characteristic sound will appear, indicating that the fuel pump is starting. After the latter turns off, it is necessary to check the connections of all components, noting any fuel leaks.

After completing all the manipulations, you need to start the engine and make a short trip. After this, it is recommended to check the specified connection points again. If a leak is detected, you need to tighten the fastenings (fix them more firmly) of the hoses. If this does not help, then the gaskets in the pipes should be replaced.

When is it necessary to replace the fuel filter on a Renault Sandero with a gasoline engine?

Some car enthusiasts believe that the filter structure in the fuel system of any car is designed for its entire service life. This concept, to put it mildly, does not quite correspond to our realities. Even if the owner is confident in the quality of the fuel and follows a gentle driving style, symptoms of fuel shortage will sooner or later appear.

It is possible that replacing the fuel filter and a video of operating moments on a Renault Sandero will help the car owner understand the processes of simple repairs, but it will not hurt to find out the symptoms of a clogged filter element. Signs of such a malfunction are:

1. Unstable operation of the power unit.
2. Reduced power.
3. Increased fuel consumption.

Experienced car enthusiasts can identify the cause of pollution at an early stage, even if it is not so obvious. The inability to start the engine indicates an extreme degree of clogging, but you need to understand that this can also lead to the need for quite complex and expensive repairs.

Judging by the manufacturer's recommendations, replacing the fuel filter on a Renault Sandero with an eight-valve engine should be carried out no more often than every 120,000 km. However, experts strongly advise owners of domestic cars to change this unit more often after driving 45,000 km. In any case, during operation you should listen to the behavior of the car, because in practice the interval between gas filter replacements can be reduced to 10-15 thousand kilometers.

When is self-repair possible?

Do-it-yourself electronic board repair without the involvement of specialists is possible in case of the following breakdowns:

• Malfunction of the control sensors. As a rule, this failure occurs due to clogging or greasy contacts in the adjustment knob. Signs of damage:
• Malfunction of the programmer sensors. Mainly occurs due to clogging and clogging of the contacts in the adjustment knob. Main symptoms: the regulator rotates quite tightly, there is no distinct click when it rotates. To eliminate the breakdown, clean the regulator knob.
• Presence of carbon deposits. As a rule, this applies to old units. Carbon deposits usually accumulate on the filter power coils. You can fix the problem with a brush or a regular rag;
• Malfunction of the sunroof lock sensor. Mainly occurs due to its being washed out or greasy. Cleaning it is also enough to resolve the issue;
• The machine does not start or the drum speed is unstable. To eliminate this breakdown, it is necessary to tighten the pulley;
• The metal part of the washing machine receives an electric current, as a result of which the control module can block the operation of the unit. To solve this problem, you should ground the washing machine.

Replacing the fuel filter for Renault Sandero up to 2007

Instructions for replacing the autonomous fuel filter:

• The first step is to relieve the pressure in the fuel line. It is necessary to start the engine with the fuel pump de-energized. To do this, remove the fuse from the pump or disconnect the terminal on the fuel module.

• Squeeze the clamp and remove the tee from the fitting.

• Remove the fuel line.

• Remove the filter.

• Install the new filter, checking the direction of fuel flow.

Conclusion

The engine ECU is perhaps the most critical element of a car's on-board electrical system. Thanks to it, the power unit has optimal performance, exhaust composition and high stability. ECU malfunctions occur frequently, but in most cases they are caused by a problem with some electrical or electromechanical element of the car. If the problem lies precisely in the ECU, then often the only way to solve it is... an expensive replacement of the unit. We advise you to contact trusted specialists for diagnostics, and only then make plans for purchasing the necessary spare parts and their further installation.

Which to choose

Renault Sandero has been produced with various engines throughout its history, each equipped with its own filter elements. In this regard, when choosing components for a French sedan, it is necessary to take into account both the year of manufacture and the type of engine installed.

Sandero until 2007

The first generation Renault Sandero was equipped with two petrol engines. The filter element in the first modifications of the sedan was located separately from the other components of the fuel system. Components with the following codes are suitable for this version of the sedan:

• 7700845961;
• 15270370579;
• 6000591768;
• 7701068107.

In addition to the original fuel filters for Renault Sandero, produced before 2007, components from Bosch 0450902161, Knecht KL248 and WIX WF8034 are suitable. It is also possible to install similar components on the French model for Opel Vivaro (4408101), Smart (4534700400) or Peugeot 106, 206 and 306 (156793 and 156785).

Sandero after 2007

It is not possible to purchase a separate fuel filter for Renault Sandero produced after 2007, since this part was installed in a separate unit along with sensors, float and other components. This design is produced under article number 6001547605. Due to the fact that this module costs about 17.5 thousand rubles, owners of French sedans often install the following analogues:

• France FCR210113;
• Period 775120;
• Asam 30290.

For diesel versions of the first generation Renault Sandero, a fuel filter with number 164002137R is suitable. As a replacement, you can purchase analogues from WIX (WF8455), SCT (ST785) or Purflux (FCS772A).

Starting from the second generation, all Renault Sandero cars are equipped with the above module with a main filter element. This version of the sedan is equipped with the same set of components as the first generation model.

Diesel Sandero

For diesel modifications of the second generation Renault Sandero, a cassette filter is used, sold under article number 164039594R.

The cost of the original component is approximately the same as that of its analogues. But if the specified details could not be found, you can use the following:

• 1640000Q2D (from Nissan Note);
• A6070900752 (from Mercedes-Benz Citan);
• F026402825 (Bosch);
• C11574 (FRAM);
• KX338/26D (Knecht).

When purchasing filters for Renault Sandero that are suitable for other cars, it is recommended to take into account the year of manufacture of the latter. New versions of these models may be equipped with components that are not suitable for the French sedan.
