The Volkswagen Polo has a wide range of engines installed in the engine compartment.
It includes three-cylinder and four-cylinder engines with different volumes and a wide spread of power.
The main thing that unites all Volkswagen Polo power plants is the absence of serious design flaws, high reliability and great durability of all engines.
The engines comply with environmental requirements and are characterized by low fuel consumption.
Three-cylinder engines that power the Volkswagen Polo
The Volkswagen Polo is powered primarily by gasoline engines. There are also options with a diesel engine. They have not found wide distribution in the domestic market. The volume of installed three-cylinder power units ranges from 1.0 to 1.4 liters.
The most economical petrol engine is the 1.0 TSI Blue Motion. Despite its liter volume, it produces decent performance. Its power is 95 horsepower.
At the same time, the engine develops a torque of 160 Nm. The manufacturer has modernized the power unit, resulting in 110 horsepower and 200 Nm of torque under the hood of the Volkswagen Polo. These figures are very respectable for a three-cylinder engine.
One of the small engines installed on the Volkswagen Polo is the in-line three-cylinder EA 111. This is a Czech engine, the design of which began in the mid-70s. The engine was migrated from the Audi 50, so it is practically free of childhood diseases. It has a displacement of 1.2 liters and produces 70 horsepower. Volkswagen Polo was equipped with this engine until 2014. New cars have more powerful internal combustion engines.
In 2009-2013, the three-cylinder turbo diesel 1.2 TDI BlueMotion gained wide popularity. The engine consumed up to 3.4 liters of diesel fuel per 100 kilometers. The engine was subsequently replaced with a more powerful 1.4 liter TDI BlueMotion. In 2016, the power unit was modernized, allowing it to remain competitive today.
Design features of the motor
Initially, the car was equipped with an engine with two different boost levels: CFNA and CFNB with a stated power of 105 and 85 horsepower, respectively. The engine is an inline four in an aluminum block with thin cast iron liners, a long stroke crankshaft (86.9 mm) and cylinders with a nominal diameter of 76.5 mm. In 2015, the manufacturer introduced a new engine, labeled CWVA. The power of the power unit was increased to 110 horsepower, and the main purpose of the development was to replace the CFNA modification.
The modified power unit has the following characteristics:
- Torque equal to 155 Nm;
- Collaboration with various transmission variations;
- Vehicle acceleration up to 195 km/h;
- Consumption of up to 6 liters of fuel in mixed mode.
During the improvement of the engine, the manufacturer faced a difficult task - to reduce the nominal weight of the engine and bring its efficiency indicators up to Euro-5 standards. By reducing the weight of the crankshaft and cylinder block, the designers managed to achieve the desired result. The engine from the EA211 series has become lighter than the previous modification by as much as 10%, while distinguishing itself with decent efficiency indicators and a lower level of exhaust toxicity.
Four-cylinder powertrains of the Volkswagen Polo
Most Volkswagen Polo sedan and hatchback cars are equipped with four-liter power units with engines ranging from 1.1 to 1.9 liters. The most popular engines were 1.4 and 1.6 liters.
A cheaper option is Volkswagen Polo cars with 1.6 liter engines. They have a power of 90 hp, 105 hp and 110 hp. Power plants have positive reviews from car owners. They are reliable and durable. The latest design upgrade was carried out in 2022. The most popular today is the 1.6-liter CFNA engine.
Unlike the domestic market, the 1.4 TSI engine is gaining popularity outside of it. It is the most dynamic. The operation of these power plants is accompanied by the need to use only high-quality fuel and synthetic motor oil.
SALON
The driver's door window regulator often lives its own life.
This mainly manifests itself in the fact that when lowering, it only fires after holding the button for ten seconds.
The plastic steering wheel wears out pretty quickly.
Leather begins to give up only after 100,000 km. Some owners managed to change it under warranty at low mileage, but these were isolated cases.
The heating elements of the front seat cushions do not last long.
Over time, they give way under human weight. The original heating element for the pillow is available as a separate spare part, but it is expensive: the price is about 8,000 rubles.
Refrigerant pressure sensor failure
- a common malfunction. Because of this, the air conditioning compressor stops turning on. The sensor is sold as a separate spare part, and inexpensively.
It is rare to have to change the compressor clutch,
which reports a problem with an annoying rumble when it is turned off. For some unknown reason, this problem happens much more often with the Skoda Rapid platform liftback.
Word to the seller
Polo Sedan is rightfully one of the top three class leaders. It has good liquidity and, in terms of its consumer qualities, is not far behind the first-generation Solaris/Rio pair. However, the “Koreans” of the second generation moved quite far from the Russified “German”.
Polos in almost any configuration are in demand on the secondary market. You should only avoid the basic versions without air conditioning and with derated 1.6 engines (85 and 90 hp) - they were bought mainly by taxi companies, and cars without air conditioning are now practically no use for anyone. Manual and automatic versions sell equally well. Cars with climate control are valued. Depending on the year of manufacture, this option adds up to 70,000 rubles to the price of cars with conventional air conditioning. By the way, this situation is typical not only for Polo.
I recommend considering cars with a manual transmission that cost no more than 500,000 rubles. A reasonable ceiling for versions with an automatic transmission is 600,000 rubles. It’s better to choose a car with good equipment: it will be more pleasant to drive and easier to sell later. Such cars, especially with an automatic transmission, lose less value than others. And carefully study the history of the car, because the Polo Sedan is one of the most popular taxis.

Main technical characteristics
Volkswagen Polo has a wide range of engines used. The range of volumes of fuel consumed per 100 kilometers is from 3.4 to 12 liters. In real conditions, many car owners note an increase in fuel consumption up to 15-17 liters. In most cases, this is due to difficult road conditions or malfunctions in the car.
Fuel consumption according to the technical specifications for the most popular engines equipped with automatic and manual transmissions is shown in the table below.
The best acceleration performance is achieved by Volkswagen Polo cars, which have 1.4-liter power plants under the hood. This characteristic for popular Volkswagen Polo models is given in more detail in the table below.

Boxes Polo Sedan
The Polo Sedan is equipped with a five-speed manual transmission or a six-speed Tiptronic automatic transmission. Transmissions have proven themselves in terms of reliability, but in the domestic market the version with manual transmission is more common. The manual transmission contains 2 liters of oil, which is advisable to change if you bought a car from the secondary market with a mileage of more than 100 thousand km. After all, lubricant tends to become dirty and lose its basic properties. The automatic uses 7 liters of ATF, and the working fluid must be replaced every 80 thousand km.
To extend the life of a mechanical transmission, we recommend using the RVS-Master Transmission Tr3 composition. This is a friction geomodifier that restores working surfaces and protects them from future wear. Thanks to the use of the composition, it will be possible to minimize the amount of noise and vibration, extend the life of the manual transmission, and achieve easy and precise gear shifting.
The RVS-Master Transmission Atr7 additive is suitable for a six-speed automatic transmission. It forms a cermet layer on the contact parts, thereby eliminating wear and characteristic kicks when switching.

Engine life
Many car enthusiasts are wary of three-cylinder engines. It is believed that their motor life is too short. Three-cylinder engines installed in the Volkswagen Polo can cover 300,000 kilometers before major overhaul. This figure is very impressive and debunks the idea of low durability of three-cylinder power plants.
Of the entire line of engines, the most reliable and durable is the 1.6-liter unit.
It is the least sensitive to fuel quality and maintenance compliance. For this reason, the Volkswagen Polo with a 1.6 engine has gained the greatest popularity in the domestic market. The engine life is 250-400 thousand km before major overhaul. According to reviews from car owners, the engines of cars produced in 2011-2012 are the most reliable.
The 1.4 TSI power units are characterized by the least reliability. They operate under high thermal load. The use of low-grade consumables or violation of maintenance intervals often leads to scoring on the cylinders. With proper treatment of the engine, its service life is about 230-250 thousand km.
Tips and tricks
Naturally, as in any other case, the service life of any engine will greatly depend on the first kilometers. We are talking about running in a new engine in compliance with all recommendations and regulations. In this case, the Polo sedan is no exception. And you shouldn't rely on the stated 2 or 3 year warranty.
Let's go further, for the accurate and correct selection of “consumables” the engine number and its markings will greatly help. On a sedan from Kaluga, the serial number is located on the cylinder block under the thermostat housing. Since the internal combustion engine is new, such information greatly facilitates the selection of engine oil, original spare parts or replacements from catalogs.
By the way, when choosing oils for this model, it is important to pay attention to the viscosity, which should be 5W30 or 5W40, as well as the tolerances. The oil must have approval VW 501 01, VW 502 00, VW 503 00, VW 504 00. ACEA A2 or A3 standard.
As for the manufacturer itself, some sources contain information that Castrol oil is poured into the Polo sedan engine during production. To change the oil, you need to buy about 4 liters; the manufacturer himself recommends pouring 3.6 liters into the engine, and the rest can be stored for topping up. This also needs to be monitored, since overfilling the engine with oil can cause certain problems.
We also recommend reading the article about what an FSI engine is. From this article you will learn about the advantages and disadvantages of motors of this type, as well as what features this power unit has.
There is also information that power units undergo a so-called “cold run-in” of the engine right at the factory. Managers at car dealerships emphasize that it is for this reason that engines do not need additional running-in. However, in practice, experts pay attention to the fact that the engine, even the most modern one, still needs to be broken in.
The rules are quite simple: you must avoid driving without warming up, abrupt starts, active braking, driving at a constant speed and at the same speed, driving in high gears, too high and too low speeds, driving uphill in high gear, engine braking, towing a trailer. etc.
In other words, during break-in there is no need to “load” the engine for at least the first thousand km. Also, after the first thousand, the oil and oil filter need to be changed, and always use high-quality gasoline not lower than AI-95. Then the next oil change is expected at 3 thousand km, and the 10 thousand km mark can be considered the complete completion of the break-in. After this, the oil is changed again, and the engine can continue to be gradually loaded.
Typical problems of power units
The most common problem, typical for the entire line of engines, is the presence of extraneous knocks during engine operation. The reason for this is the design feature of the pistons and the tightness of the intake manifold. A knocking sound appears after 20 thousand kilometers on a cold engine. Gradually, extraneous sounds begin to be present when the engine is warmed up.
The updated 1.6-liter engine with 110 horsepower received a timing belt and a plastic intake manifold. This brought shortcomings to the motor. Many car owners complain that cracks appear on the manifold and that the engine bends the valves when the belt breaks. The chain drive of the 105-horsepower unit is many times more reliable.
The most common power plant breakdowns that Volkswagen Polo car owners encounter are:
- sensor damage;
- cracks in the supports of the power unit;
- occurrence of piston rings;
- increase in crankcase gas pressure;
- The valve cover is sweating.
Exhaust manifold problems, configuration errors and mechanical defects
One of the CFNA powerplant's glaring weaknesses is the poor design of the exhaust manifold. The exhaust channels are of different lengths, and the catalyst is located too close to them. As a result, the following difficulties in the operation of the system are observed:
In addition to the indicated disadvantages associated with design features, the CFNA motor has another disadvantage. In some cases, the exhaust manifold cracks between the 2nd and 3rd cylinders. The best option is to replace the collector; even with high-quality welding, the crack appears again after some time.
The feasibility of repair and replacement with a contract motor
When the power plant completely exhausts its resource, the car owner is presented with many options to revive his car. Some of them are:
- superficial engine repair;
- major overhaul of the power plant;
- purchase of a contract motor;
- purchasing an engine from a domestic car wrecker.
As a result of superficial engine repairs, problems that interfere with engine performance are eliminated. At the same time, breakdowns occur at regular intervals, since most of the elements have exhausted their service life.
The cost of such repairs is no more than 10,000 rubles. This type of restoration is recommended only in case of the next sale of the machine or in case of irregular use of it.
Major repairs allow you to restore up to 70-85% of the service life of a new unit. It is recommended to carry out it in the absence of difficult to eliminate consequences of operating the power plant. The cost of major repairs is about 30-50 thousand rubles.
Purchasing a contract engine from a foreign dismantling site is one of the radical ways to solve problems with the exhaustion of the power plant's resource. The price of such a motor ranges from 20 to 60 thousand rubles. It is quite difficult to estimate the residual life when purchasing an engine. It is worth noting that among the contract power plants there are quite a lot of units capable of covering 70-120 thousand km without serious financial investments for repairs. The photo below shows a typical engine from a foreign car wrecker.
Purchasing a motor at domestic car dismantling yards is quite a risky endeavor. In most cases, it is impossible to know the actual mileage, since it is repeatedly twisted, passing through the hands of intermediaries. Therefore, you can purchase a used engine from domestic car dismantling yards only after a personal inspection with a familiar auto mechanic or motor mechanic. The cost of such a unit is 15-35 thousand rubles.
Wear resistance of Hyundai Solaris
Of course, the so-called factory resource is very different from the actual one. And if one driver can easily drive a Hyundai for 200, or even 300 thousand km, then another will manage to kill the engine in 50.
The situation is aggravated by the fact that for the engine of this model there is no such thing as a major overhaul. If there is no proper care for it, you will simply have to replace it with a new one, paying at least 50 thousand rubles for this pleasure.
The problem is that the manufacturer does not produce spare parts for many motor elements. If aluminum pistons or cylinder walls fail, there will be nothing to replace them with.
Recommendations for choosing a Volkswagen Polo car with various power plants
According to reviews from car owners, it is best to purchase a Volkswagen Polo with a 1.6-liter gasoline engine. The most modern engine has 110 horsepower. This is quite enough for comfortable driving both in heavy traffic and on the highway. The motor is not whimsical and has a good resource.
If the car owner’s priority is the car’s dynamics, then you should take a closer look at the 1.4 TSI petrol engine or 1.9 liter diesel engine. They have excellent technical characteristics and are able to provide a sporty driving style for the driver.
For those who want to save on fuel, there are three-cylinder versions. It should be borne in mind that you should not expect good dynamics from a 1.0-1.2 liter power plant. Despite this, the low power engine will not cause problems when driving in city traffic.

When I bought the car, I didn't read the forums well. But it turned out that everything was very serious with the engine. This topic https://vwts.ru/forum caused sadness. pic=201365&st=0 , and then this one https://www.polosedan. php?f=39&t=8549 I don’t know, maybe you can’t give links to these forums here, but it seems to me that people should know what kind of hemorrhoids they can buy. Now the machine doesn't make me very happy.
Honestly, right now I just don’t have time to read everything from beginning to end. Did they get to the bottom of the reason for the knocking, or did they stop at complaining and collecting signatures?
Look, with TSI motors they didn’t immediately find the cause of the phase shift. there must also be some reason here, because most of the Polosedans still do not suffer from this.
but in general: the less you know, the better you sleep! and one of my friends - when he bought a Honda at one time, and they told him, they say, take a Toyota, it’s easier and cheaper to repair - he said that he chooses a car not so that it is easier to repair, but so that it drives better!
Design
The structural differences of the CWVA from its predecessors (CFNA, CFNB) lie in the layout of the exhaust manifold with the cylinder head (now it is a single whole), equipping the intake camshaft with a phase shifter, a modified cooling system, changing the timing drive to a belt drive and an improved exhaust gas cleaning system.
Changes in the mechanical part of the internal combustion engine increased its power to 110 hp. s, and torque up to 155 Nm. At the same time, the unit has become more reliable in operation and easier to maintain, which is important for the Russian consumer. It is appropriate to note here that CWVA is not supplied to the European market, since it was developed specifically for the CIS market.
The engine is configured according to the MQB modular system. In other words, all motor components come in modules. In addition to simplifying the design, this approach significantly reduced the cost of producing the unit.
CWVA engine modules (without turbine and intercooler)
The cylinder block is made of aluminum alloy. Cast iron sleeves are mounted inside. Hon is applied to the working surfaces.
Aluminum pistons. Floating type piston pins. Secure with locking rings.
The connecting rods are steel, stamped.
The cylinder head is aluminum, with two camshafts and 16 valves. Compared to its predecessors, it has been rotated 180° (the inlet is located at the front). The valves do not require manual adjustment of the thermal gap, as they are equipped with hydraulic compensators. The exhaust manifold combined with the cylinder head ensures rapid heating of the catalyst, which in turn reduces the degree of pollution of the exhaust gases.
The timing belt is belt driven. The manufacturer determined the belt resource to be 120 thousand km. But experienced car enthusiasts and service station mechanics recommend inspecting the belt every 50-60 thousand km. At the same time, according to reviews from car owners, with proper operation and timely maintenance of the engine, the declared resource is significantly exceeded. The timing belt requires close attention, since if it breaks when it meets the pistons, the valves bend. And this is a serious and quite expensive engine repair.
The power system is injection type, with multi-point distributed fuel injection - MPI (Multi Point Injection). The peculiarity lies in the mandatory presence of a cooling circuit for the air-fuel mixture (structurally included in the engine cooling system). The need to solve the cooling issue is caused by a rather impressive difference in the temperatures of the injected gasoline and the upper part of the cylinder liner associated with the combustion chamber in the cylinder head. The cooling circuit prevents the occurrence of gas-air plugs. Another distinctive feature of the MPI internal combustion engine is the absence of a turbocharger.
The engine cooling system deserves special attention. The pump is of interest. It is made of plastic, has an individual drive and two thermostats. Despite its apparent fragility, it easily maintains 200 thousand km without breakdowns. Structurally, the pump is monoblock and cannot be repaired. The total service life is 8-9 years.
