Malfunctions
The VW 1.6 bfq engine is considered to be quite reliable, allowing you to drive more than 300 thousand km without major repairs, however, it also has a number of typical malfunctions, some of which are shown in the table.
FAULT | CAUSE |
The engine is unstable (the crankshaft speed floats in idle mode). | The injectors, throttle valve, and idle air control may be faulty. |
Increased engine oil consumption. | Worn piston rings. Oil seals are damaged. |
Extraneous knocking noises during operation of the power unit. | The intake manifold has failed. Faulty hydraulic valve compensators. |
An unpleasant feature that owners of cars equipped with a bfq engine often encounter is the strong vibration of the engine during operation. You can eliminate this defect:
- flashing the electronic engine control unit;
- increasing the crankshaft speed in idle mode.

Price in Russia
Unfortunately, there is no official information on the cost of the 2020 Skoda Kodiak all-wheel drive crossover in our country yet, but according to some rumors the price will be about 1,890,000 rubles. The main competitors can be considered:
- Kia Sorento price 1,594,900 – 2,154,000 rubles;
- Kia Sorento Prime price 2,249,900 – 2,609,900 rubles;
- Hyundai Santa Fe Premium price 1,844,000 – 2,397,000 rubles;
- Mitsubishi Outlander price 2,499,000 rubles;
- Nissan X-Trail price 1,409,000 – 1,999,000 rubles.
The advantages of Kodiaq include:
- practicality;
- spacious interior;
- comfortable seats;
- comfort;
- excellent touch display;
- dynamics;
- controllability;
- high quality of materials used;
- ergonomics.
Flaws;
- a cramped third row that can only accommodate children;
- controversial front design;
- high price.
To summarize, we can say that Czech manufacturers managed to create a good family car that is suitable for traveling long distances. To achieve this, the crossover has an economical and dynamic engine, a spacious interior designed for a large family and proper comfort. But unfortunately the car is not well suited for off-road use; the Kodiak has an excellent all-wheel drive system based on the 5th generation Haldex, but the overhangs and long wheelbase spoil everything. On the other hand, most potential owners buy such cars for driving in the city, for which the Kodiak is ideally suited.

Engine Skoda Octavia A5
Skoda Octavia cars are equipped with transversely mounted four-stroke four-cylinder petrol injection 8-valve engines with a displacement of 1.6 liters. as well as 16-valve engines with a displacement of 1.4 liters with turbocharging and 2.0 liters with direct injection. The engines are highly efficient and meet the requirements of the Euro-5 standard.
The operation of a piston internal combustion engine is based on the use of thermal expansion work of heated gases during the movement of the piston from top dead center (TDC) to bottom dead center (BDC). Heating of gases in the TDC position is achieved as a result of combustion of fuel mixed with air in the cylinder. At the same time, the gas temperature and pressure increase. Since the pressure under the piston is equal to atmospheric pressure, and in the cylinder it is much higher, the piston will move downward under the influence of the pressure difference, and the gases will expand, doing useful work. In order for the engine to continuously produce mechanical energy, a mixture of air and fuel must be periodically supplied to the cylinder through the intake valve. The products of fuel combustion after their expansion are removed from the cylinder through the exhaust valve. These tasks are performed by the gas distribution mechanism, which controls the opening and closing of the valves, and the fuel supply system. The engine operating cycle is a periodically repeating series of sequential processes occurring in each cylinder of the engine and causing the conversion of thermal energy into mechanical work. Car engines typically operate on a four-stroke cycle, which is completed in two revolutions of the crankshaft or four strokes of the piston and consists of intake, compression, expansion (power stroke) and exhaust strokes.
Features of the design of the 1.6 liter engine The design features of the engine are considered using the example of a 1.6 liter engine as the most common.
The engine is mounted transversely at the front of the car.
Engine (front view in direction of travel): 1 - oil sump; 2 - oil filter; 3 — auxiliary drive pulley; 4 - generator; 5 — thermostat housing; 6 — knock sensor; 7 — intake manifold; 8 — oil filler neck; 9 - bypass valve; 10 — additional air pump; 11 — automatic transmission selector position sensor; 12 — oil pressure sensor; 13 - starter; 14 — crankshaft position sensor; 15 — gearbox sensors
Engine displacement (displacement) is one of the most important design parameters of an internal cropping engine (ICE), expressed in liters (l) or cubic centimeters (cm3). The engine displacement largely determines its power and other operating parameters. It is equal to the sum of the working volumes of all engine cylinders. In turn, the working volume of the cylinders is determined as the product of the cross-sectional area of the cylinder and the length of the piston stroke (from BDC to TDC). According to this parameter, a distinction is made between long-stroke engines with a piston stroke length exceeding the cylinder diameter, and short-stroke engines with a piston stroke less than the cylinder diameter.
Engine (rear view in direction of travel): 1 — gearbox; 2 — automatic transmission heat exchanger; 3 — mounting area for the left suspension support of the power unit; 4 - water distributor; 5 - bypass valve; 6 — throttle assembly; 7 — oil filler plug; 8 — adsorber valve; 9 — intake manifold receiver; 10 — timing belt flap; 11 — bracket for the right suspension support of the power unit; 12 — control oxygen concentration sensor; 13 — cylinder block; 14 — crankshaft pulley; 15 — oil drain plug
The engine cylinder head is made of aluminum alloy according to a transverse cylinder blowing pattern (intake and exhaust channels are located on opposite sides of the head). Valve seats and guides are pressed into the head. The intake and exhaust valves have one spring each, fixed through a plate with two crackers.
The separation plane between the head and the cylinder block is sealed with a gasket, which is a plate molded from thin sheet metal.
The cylinder block is a single casting that forms the cylinders, cooling jacket, upper crankcase and five crankshaft bearings designed as crankcase baffles. The blocks are made of aluminum alloy with cylinders bored directly into the body of the block. The main bearing caps are machined together with blocks and are not interchangeable. The cylinder blocks have special bosses, flanges and holes for fastening parts, assemblies and assemblies, as well as channels for the main oil line.
The crankshaft rotates in main bearings that have thin-walled steel liners with an anti-friction layer. The axial movement of the crankshaft is limited by two half-rings installed in the grooves of the middle main bearing bed.
The flywheel is cast iron, mounted on the rear end of the crankshaft and secured with six bolts. A toothed rim is pressed onto the flywheel to start the engine with a starter. In addition to it, the flywheel has a gear ring that ensures the operation of the top dead center sensor of the engine control system.
The pistons (Fig. 5.3) are made of aluminum alloy. On the cylindrical surface of the piston head there are annular grooves for the oil scraper ring and two compression rings.
The piston pins are installed in the piston bosses with a gap and pressed with interference into the upper heads of the connecting rods, which are connected by their lower heads to the crankpins of the crankshaft through thin-walled liners, similar in design to the main ones. The connecting rods are steel, forged, with an I-section rod.
The camshaft is driven from the crankshaft by a toothed belt. The camshaft support covers are combined into a monolithic frame structure. The intake and exhaust valves are closed using coil springs and move in guide bushings pressed into the cylinder head. The camshaft cams drive the valves through roller oscillating arms supported by hydraulic lash adjusters.
Combined type lubrication system. Lubricant enters the engine from an oil pump driven through a chain and a sprocket from the toe of the crankshaft. The pump takes oil from the oil pan through a strainer and forces it through a full-flow replacement oil filter mounted outside the engine. Next, the oil flows through the channels into the cylinder block, from where it is distributed to the support (main) bearings of the crankshaft and the camshaft to the cylinder head. Oil is supplied to the connecting rod journals through drillings in the crankshaft; oil is supplied to the camshaft bearings and hydraulic compensators under pressure. Cams and valves are splash lubricated, just like all other moving engine components. To cool the oil, an oil-liquid heat exchanger is built into the lubrication system.
The closed crankcase ventilation system does not communicate directly with the atmosphere, therefore, simultaneously with the suction of gases, a vacuum is formed in the crankcase under all engine operating modes, which increases the reliability of various engine seals and reduces the emission of toxic substances into the atmosphere.
The system consists of two branches, large and small.
When the engine is idling and at low loads, when the vacuum in the intake pipe is high, crankcase gases are sucked into the intake pipe through a small branch of the system.
At full load conditions, when the throttle valve is open to a large angle, the vacuum in the intake pipe decreases, and in the air supply hose it increases, and crankcase gases through the large branch hose connected to the fitting on the cylinder head cover mainly enter the air supply hose, and then through the throttle assembly into the intake pipe and engine cylinders.
The engine cooling system is sealed, with an expansion tank, and consists of a cast cooling jacket surrounding the cylinders in the block, combustion chambers and gas channels in the cylinder head. Forced circulation of coolant is provided by a centrifugal water pump driven from the crankshaft by a timing belt. To maintain the normal operating temperature of the coolant, a thermostat is installed in the cooling system, which closes a large circle of the system when the engine is not warmed up and the coolant temperature is low.
The engine power supply system consists of an electric fuel pump installed in the fuel tank, a throttle assembly, a fine fuel filter installed under the tank, a fuel pressure regulator installed in the fuel pump module, injectors and fuel lines, and also includes an air filter.
The engine ignition system is microprocessor-based and consists of an ignition module, high-voltage wires and spark plugs. The ignition module is controlled by the electronic engine control unit. The ignition system does not require maintenance or adjustment during operation.
The power unit (engine with gearbox) is mounted on two supports with elastic rubber elements on the right and left side, which absorb the bulk of the power unit. The lower jet thrust compensates for torque from transmissions and loads that occur when the vehicle starts, accelerates, and brakes.

Body
The car appeals to several of the latest styling trends, meaning a fairly neutral design. There are no fireworks, but it's also hard to talk about boredom - everything is made to order and looks very good. The lighting that looks best is made up of tiled headlights with dark filling and taillights that span the tailgate. The headlights are also covered with plastic covers that run along the lower edges of the housing.

Photo report It all started with the fact that the car began to start worse. The battery seems to be normal, it’s not cold outside. Having measured the charge with a tester, I saw 14.3-14.4. I calmed down, but in vain. Symptoms of undercharging continued. I decided to measure the charge not after starting the car, but after 30-40 minutes of driving and everything became clear - the tester showed 13.78-13.85. And this is not enough. If it's a short trip and I turn off the car several times, it's already difficult to start. Solution: generator analysis...
