Description

Volkswagen Polo interior unit relay

All relays in the car are located on a separate mounting block, which is located in the dashboard on the left side of the driver.

• R4 - pressure gasoline supply relay.
• R3 - starter blocking relay.
• R9 - air conditioning relay.
• R7 - relay for headlights. See fuses 57 and 58.
• R8 - fuel pump relay.
• R5 - power relay.
• R6 - spare seat.
• R10 - relay contact “X”.
• R1 - reserve seat.
• R11 - R15 are reserved.
• R2 - windshield heating relay. See fuse 56.

Cigarette lighter repair

The standard device is a collapsible module - in fact, it can be repaired if a malfunction is detected. On a VW Polo, the unit does not need to be repaired. The parts are sold assembled and are cheap.

Usually the entire part is removed from the car and replaced with a known good one.

Causes of cigarette lighter failure

Among the common occurrences, factors stand out.

• Use of the device for purposes other than its intended purpose. Individual drivers often use the device as a charger or power source for powerful consumers. The device cannot withstand the load and fails.
• Short circuit in the network. Water ingress, damage to wiring and loosening of contacts provoke short circuits and failure of the unit.
• Careless use of the device. Each unit must be operated carefully. Over time, the fasteners and body of the device may become deformed.

How to remove and disassemble the cigarette lighter

The principle of the procedure is the same for cars 2011-2016. The bottom line is that the design of the part is quite primitive and does not require modification.

To disassemble the cigarette lighter you will need to follow a sequence of steps.

• Disconnect the car.
• Using a special tool or a “homemade device”, press out the core fastening terminals.

• After this, remove the cigarette lighter from the plastic socket.

• Next, you will need to disconnect the terminal of the contact group and dismantle the device.
• The next step is to remove the plastic casing of the device. To do this, you need to take an awl or a thin screwdriver and pry off the expansion clamps.
• After this, the socket can be removed and the contacts from the backlight bulb disconnected.

Troubleshooting the food chain

On 2022 cars, some users encountered problems with the cigarette lighter line. Similarly, faults can appear in older cars.

To find and eliminate the malfunction, the entire circuit must be completely checked. The procedure begins with diagnosing the fuse. Next, the power line and the cigarette lighter itself are diagnosed.

Changing the backlight bulb

In rare cases, the light on the cigarette lighter burns out. To replace the illuminator lamp, you will need to dismantle the device and disassemble its housing. A standard lamp of a fairly common standard size is used inside.

Block "B" and instrument panel relay block

The larger fuse box B is located inside the vehicle. It is located under the steering column. Access is not difficult. Just lower the lid and the sesame will open. For ease of working with devices, small tweezers are built into the socket of the mounting block of the Volkswagen Polo sedan.

The layout looks a little more confusing than previous configurations. Therefore, if you have to replace “plugs” in a block, it is better to have a drawing on hand with a detailed designation of each element.

It’s immediately worth noting the fuses that “go” to reserve: 1.5.28−31.41.60. In addition, slots can be “reserved”: 8 and 32. “Otto” can be used to protect engine injectors and connector “32” for the fuel pump.

Lighting devices include a group of devices that consume large amounts of energy:

• contact “21 °” is responsible for the interior lighting and luggage compartment (10A).
• The reversing light switch in the right lamp is switched off thanks to slot 27 (5A).
• "Fog" - 54 (15A).
• Brake lights and direction indicators - 43 (15A).
• The dimensions of the left headlight and left rear light are 57 (5A).
• Right headlight: high beam - 34 (7.5 A), low beam - 39 (10 A).
• Rear fog lamp - socket 18 (5A).
• Left headlight: high beam - 38 (7.5 A), low beam - 59 (10 A).
• The direction of the headlight beams is determined by special regulators. Two fuses are used for them: the “seventh” (also checks the glow of the numbers) and the “eleventh” (starts the gearmotors in the headlights). Both elements have a current strength of 5A.
• The dimensions of the right headlight and right rear light are 58 (5A).

Several fuses control the engine and drive at the same time: 3 (5 A), 13 (15 A) and 23 (7.5 A). The electrical circuit of the control unit includes fuses that control various vehicle functions. This group may include:

• Side light relay and main sound reproduction unit 19 (5A).
• Heated rear view mirrors - 24 (5A).
• Central locking and fuel filler neck - 48 (25A).
• Windshield washer motor - 47 (20A).
• Heated rear window - 53 (30A).
• Heated seats - 37 (25A).
• Automatic transmission and speed switch - 13 (15A).
• Sound signal - 46 (20A).
• Speed ​​sensor, ignition switch and automatic selector - slot 10 (5A).
• Heated windshield - 56 (40A).

A large group consists of “plugs” that protect the heating and air conditioning system: 22 (5A), 25 (5A) and 40 (30A). The steering column switches include the following fuses: 2 (10A), 4 (2A), 20 (5A).

In total, the “plug” of the interior circuit has 60 connectors. It is difficult to remember the location of each element, so it is recommended to check the position of the fuses before replacing a damaged link.

An important condition when replacing contacts is the current strength, which must be observed during the procedure. In other words, a jumper designed for a different current cannot be inserted into the connector. It is also strictly forbidden to use the fruits of “handicraft” developments. The “homemade products” themselves will burn out, and some of the electronic equipment of the Polo sedan will also be “taken” with them. And in the worst case, a fire that could leave the owner of a German car with nothing.

Finally, the last part of the car's wiring is the relay, located on the side of the dashboard. To remove it from the panel, you need to lift the side cover with a flat-head screwdriver and remove it. Rock the device from side to side and carefully pull it out of the hole.

The relay has 15 contacts. The last five in the chain are not used. The rest is responsible for the operation of the starter, lobovukha heater, fuel pump, low beam headlights, air conditioning compressor, and so on. If the source of the problem is in this box, we find the broken contact and change the necessary relay on it.

Thus, two conclusions can be drawn. Firstly, if one of the car components fails, you should first inspect the fuse and relay blocks - perhaps the cause of the malfunction lies in their visibility range. This will save money spent on the services of specialists at the gas station. Secondly, replacing burnt out elements will not cause problems even for a novice polo expert. It is only important to have a traffic jam diagram at hand.

Helpful information

There are a few things you need to know about fuses:

• the machine should always have suitable fuses of each type in reserve;
• Repairing this part is strictly prohibited;
• installing an unsuitable or repairable fuse can cause a fire, electrical failure or an accident;
• You cannot install fuses designed for a higher current supply than the factory part.

To protect yourself, it is important to remember that you cannot replace a removed fuse with any available parts, even for a short period of time.

Checking the health of fuses

If any vehicle device fails, it is necessary, using Tables 1 and 2, to determine which fuses are served by this element. Then you need to turn off the ignition.

In some cases (failure of the engine control unit, generator, side lights, cigarette lighter, etc.), it is better to remove the negative terminal of the battery. Then, using special dielectric pliers (you can use pliers), you need to disassemble the necessary fuses.

Testing fuses without removing them from the block may give an erroneous result.

Fuses in transparent housings can be checked visually. It should be remembered that this method of fault monitoring does not have a 100% guarantee, since sometimes it is not possible to see a microcrack in the conductive insert.

It is best to use the multimeter in the "diode", "resistance" or "continuity" test positions. The resistance value of a good fuse is approximately zero. The resistance of a blown fuse tends to infinity (the multimeter displays “1”).

Removal and replacement process

To replace, you will need a multimeter, a slotted screwdriver and a 10 mm wrench.

Under the hood

To replace the fuse in block C, simply remove the cover from it, unfasten the plastic latches and pull out the blown element with your fingers. For block A the procedure is more complicated:

1. Press the latch and open the MB cover.
2. Check the condition of the fuses:

• Switch the multimeter to ohmmeter mode.
• Apply one probe to each terminal in turn, and the second to the L-shaped metal plate. If the device shows 1 or infinity, this means that the fuse link connected to the terminal has burned out.

1. Unscrew the 5 nuts securing the terminals and disconnect them.
2. Unscrew the nut on the C block side and press the plastic lock on the battery side.
3. Remove the power fuse block.
4. Install the removed elements in reverse order.

Fuses and relays in the interior of a Volkswagen Polo sedan

The fuse box is located at the driver's feet, at the bottom of the instrument panel, under the steering wheel. The block is closed with a protective cover, inside of which there is usually a circuit for the fuse box.

Fuse box diagram for Volkswagen Polo sedan

Identification of fuses from the block cover

Description

The interior relays are located inside the control panel. To access it, you need to remove the cover from the end of the control panel on the driver's side.

Location

In a 2012 car, the required element is located at number 42 and has a rating of 15 A. In other modifications, the fuse can be installed in a different location.

The photo above shows where the fuse is located in the most popular modification common in the CIS.

Connection diagram

Fundamentally, the connection diagram of the device is no different in the sedan, hatchback or station wagon version. Below is the electrical part and the complete connection cycle of all components of the cigarette lighter power circuit.

For ease of perception, the highway is highlighted in blue.

Fuse blocks "A" and "C"

The fuse circuit is quite simple. Block A and block C are located on the Volkswagen Polo battery. Who did you miss? That's right, block B. It was hidden under the steering column in the car. In addition, inside the instrument panel on the left side there is a relay unit, an additional support for other control participants.

Has the generator stopped working or has the cooling fan stopped working on the Polo sedan? Then we go up to block A. It is in it that the fuses are located that are responsible for both parts of the car.

To access the mounting block, you need to press the lid latch and remove the “cap”. Under the cover we will find 7 fuses. First of all, the generator passes current through itself. Its power ranges from 150-175A. Next comes the ignition switch, steering column switches and various relays (low beam, fuel pump, etc.). The rated current of the fuse is 110A. Next comes the electric power steering control unit (50A), ABS and cooling system fan (40A each). Two places reserved.

Help with voltage redistribution is provided by block C. To access it, you need to disconnect the plastic clips on the sides in the engine compartment and remove the cover. 6 more fuses will burn out in front of us. Their circuit to some extent repeats that installed in block A.

Up to two slots: the first and fourth slots are responsible for the aforementioned ABS control section (25 and 10A respectively). The second and third slots control the cooling fan motor. The fifth is aimed at the correct operation of the electrical control unit. The last connector is a spare one.

How to remove and disassemble the cigarette lighter

A device equipped with such functions is found in any modern car, including the Volkswagen Polo sedan. Any car enthusiast knows where this device is. Drivers often use this device for purposes other than its intended purpose, resulting in breakdowns.

The locking device is simple. The cigarette lighter consists of:

1. Connector for connection.
2. A metal part that includes a special spiral.

The operating principle is also simple. When the button is pressed, the circuit closes, causing heat. The device has a special relay that turns off the system when the maximum temperature is reached. The circuit is open, heating stops.

Using the cigarette lighter, you can charge gadgets using special adapters. This element may fail if you connect devices that require high voltage.

The second most common malfunction is a loosening of the socket in which the receiver is located.

The cigarette lighter has 3 wires. Red is considered the main color. Another yellow wire is connected directly to the light filter, which is responsible for the correct operation of the backlight. The black wire goes last.

The most common malfunction is a broken wiring; the cigarette lighter will not work in this situation. In some cases, wires burn out due to sudden voltage surges.

The problem may arise due to oxidation of the contacts.

Sometimes the cause of a breakdown is a burnt-out element.

Repair

When the fault is resolved, the cigarette lighter must be replaced. Because of this:

1. The ignition is turned off, the hood opens to access the terminals and remove the negative terminal.
2. Small scissors with curved ends are inserted into the mandrel and removed along with the block. You can make the process easier if you press on the locking elements.
3. Then the filter latches are retracted.
4. Then a new part is installed in this place. Repairing an old element is rarely done.

Where is the fuse located

The Volkswagen Polo cigarette lighter fuse is located under the steering wheel on the right side in the first row from the edge. The fuse box is closed on top with a special plastic cover. Any driver can easily find this device without a hint. Fuse boxes in Volkswagen 2012 and 2013 problems are located there.

Check and replacement

It is difficult to replace a device without available tools if it does not work. To do this, it is more convenient to use pliers or tweezers. Determining where this part of the car is located is not so difficult - it is always blue.

The replacement procedure is as follows:

1. The cover is carefully removed.
2. Below is a fuse block, among which it is necessary to determine the one that is responsible for the operation of the cigarette lighter.
3. Its power is 15 A. The insert must be replaced with exactly the same part.

This car has a standard fuse for the cigarette lighter.

The most common malfunction of a device is the formation of a defect when it overheats. It's easy to pick out this little detail. A working fuse has a transparent body, so the metal wire is clearly visible through it. It will be complete. Faulty - wire break.

There are fuses with opaque housing. In this case, the element has a special window through which the spiral is clearly visible. If its integrity is damaged, the part must be replaced. You can repair the fuse yourself.

Improved Polo cigarette lighter illumination

Users of cars manufactured before 2010 often complain that the backlight of the standard device is not enough - the device is invisible in the dark. As an improvement, the modern market offers options.

• Replacing the standard lamp with a brighter one. In this case, a diode illuminator of similar power is ideal.
• Installing another cigarette lighter. In stores you can buy a factory version of the cigarette lighter, suitable for mounting under the car.
• Replacing the case with a model of a different color.
