SUV owners Skoda Kodiaq sooner or later they are faced with the need to undergo the next scheduled maintenance. For many car enthusiasts it is fourth maintenance becomes a turning point when the list of required work expands significantly compared to previous visits to the service. This is due to the accumulation of mileage, which is usually about 120,000 kilometers or 4 years of operation, whichever comes first.
Ignoring regulations or trying to save money on critical components can lead to costly repairs in the future. In this article we will look in detail at what exactly is included in scheduled maintenance #4 for Skoda Kodiak, what consumables will be required and what hidden defects should be paid special attention to during diagnostics.
Correct execution of all procedures at this stage ensures that the dynamic characteristics of the engine and the smooth operation of the transmission are maintained. Let's get down to specifics and look at each item on the work list.
Replacing technical fluids and filter elements
The foundation of any scheduled maintenance is the replacement of used fluids. At the 4th maintenance, it is critical to change the engine oil, since its cleaning properties are significantly reduced, and the concentration of combustion products increases. For engines of the family EA888 and EA211 specification used VW 504 00 / 507 00, which provides protection for the turbine and piston group.
In addition to the oil, the oil filter must be changed. This is a simple operation, but it prevents metal shavings and dirt from entering the lubrication channels. Don't forget to also check the condition of the cabin air filter and, if necessary, replace it with a new one to avoid problems with the air conditioning and odors in the cabin.
- π’οΈ Changing the engine oil and oil filter (volume about 5-6 liters depending on the engine)
- π¬οΈ Replacing the engine air filter (recommended every 2 maintenance)
- π«οΈ Replacing the cabin filter (carbon or standard)
Particular attention should be paid to the fuel system. If you have a diesel engine installed 2.0 TDI, replacing the fuel filter is a mandatory procedure, since clogging can lead to a drop in pressure in the rail and stopping the engine.
β οΈ Attention: The use of non-original filters with a low degree of purification can lead to premature wear of the injectors and expensive repairs of fuel equipment.
The level and condition of the brake fluid is also checked. If more than 3 years have passed since the last replacement, even with low mileage, it must be renewed, since it is hygroscopic and absorbs moisture from the air, which reduces the boiling point.
Transmission and drive system
At a mileage of 120,000 kilometers, many owners are wondering about changing the gearbox oil. For a classic slot machine DSG (DQ381 or DQ500) changing the oil in the mechanical part (in the box) and the valve body is mandatory according to the regulations every 60,000 km, which means that at the 4th maintenance this is already the second or third time. Ignoring this point is fraught with failure of the mechatronics.
In all-wheel drive versions with the system 4x4 (Haldex) it is critical to check the condition of the coupling and change the oil in the gearboxes. The rear gearbox is often forgotten to be serviced, which leads to bearing jamming and costly replacement of the unit. The front differential also requires checking the oil level and quality.
- βοΈ Changing the oil in the DSG gearbox (full procedure including filter replacement)
- π Changing the oil in the Haldex transfer clutch
- π Changing the oil in the front and rear differentials
The condition of drive belts and rollers must be checked visually. Cracks, delaminations and signs of wear on the ribs of the alternator and air conditioner belts are a signal for immediate replacement. The tension rollers should have no play or noise when rotating.
What happens if you don't change the oil in the DSG?
If you ignore changing the oil in the DSG box, over time, metal particles will begin to clog the valve body channels. This will lead to jerks, kicks when shifting gears and, ultimately, to failure of the mechatronics, the repair of which can cost more than 100,000 rubles.
The condition of the CV joint boots is also checked. The rupture of the boot and the entry of dirt into the equidistant speed joint leads to rapid destruction of the mechanism. If you hear a characteristic crunching sound when turning, this is a sure sign of a malfunction.
Regularly changing the transmission oil extends the life of the DSG gearbox by tens of thousands of kilometers and is the best investment in vehicle reliability.
Brake system and chassis
The braking system experiences enormous loads, especially if the car is used in the urban cycle with frequent acceleration and braking. At the 4th maintenance, it is necessary to measure the thickness of the brake pads and discs. If the thickness of the pads approaches the minimum value of 2 mm, they must be replaced.
Disks also have their own resource. The depth of the wear groove should not exceed 1.5 mm. Overheating of the discs can lead to their deformation (steering wheel beating when braking). In this case, you will need to groove or completely replace the discs, as well as the calipers if the guides jam.
- π Measuring the thickness of brake pads and discs (front and rear)
- π§ Checking the condition of guide supports and anthers
- π§ͺ Checking the tightness of brake pipes and hoses
SUV chassis Skoda Kodiaq It is quite reliable, but at high mileage some backlashes appear. Be sure to check the silent blocks of the front control arms, stabilizer struts and shock absorbers. Leaking shock absorbers or knocking in the suspension when driving over uneven surfaces require immediate attention.
- Every maintenance (every 2 years)
- Only when the sensor came on
- As it wears out (I check it myself)
- Once every 5 years
The steering rack must also be checked for play and leaks. On vehicles with electric power steering, it is important to check the operation of the steering angle sensor and the condition of the wiring.
β οΈ Attention: Operating a vehicle with worn brake discs can lead to their destruction and wheel jamming at high speed, which poses a direct threat to life.
Cooling system and exhaust
The engine cooling system operates in an aggressive environment of high temperatures and pressure. At the 4th maintenance, it is necessary to check the level and density of antifreeze. If the ethylene glycol concentration drops below normal (freeze protection less than -25Β°C), the coolant should be completely replaced.
Particular attention is paid to pipes and clamps. Old plastic and rubber become brittle and can burst due to sudden temperature changes. Antifreeze leakage from the cooling system is one of the most common problems at high mileage.
- βοΈ Checking the density and level of antifreeze G12++ or G13
- π Inspection of cooling system pipes for cracks
- π‘οΈ Checking the thermostat and cooling fans
The exhaust system checks the condition of the catalyst and particulate filter (for diesel versions). Soot filter DPF It should be cleaned or replaced if it is clogged. Also inspected resonator and silencer for burnouts and mechanical damage.
Before replacing antifreeze, it is recommended to wash the system with distilled water if there are traces of emulsion or rust in it to preserve the properties of the new liquid.
Electrical and diagnostics of on-board systems
Modern Skoda Kodiaq It's full of electronics. At the 4th scheduled maintenance, it is necessary to conduct a complete computer diagnostics of all control units. This will reveal hidden errors that may not be manifested by the Check Engine indicator, but affect the operation of systems.
The status of the battery is checked. Even if it still holds the charge, at large runs, its resource often comes to an end. The test under load will show the real condition of the plates and the ability of the battery to start the engine in the cold.
- π» Error reading from all control units (engine, box, ABS, Airbag)
- π Testing of the battery under load
- π‘ Checking all external and internal light sources
Driving assistance systems such as adaptive cruise control and lane assistant are also being checked. Sensors and cameras must be clean and calibrated. Errors in these systems can result in the driver assistance being turned off.
List of recommended additional checks
In addition to the mandatory items, experienced professionals recommend carrying out a number of additional checks that will help avoid sudden breakdowns on the road. This is especially true for vehicles operated in difficult climatic conditions.
It is worth paying attention to the condition of the timing belt (if your engine has one). On some engines, the belt life is 180,000 km, but a visual inspection for cracks and delaminations at 120,000 km will not hurt. If the belt is worn out, it is better to replace it preventively.
| Node/System | Typical problem at 120,000 km | Recommendation |
|---|---|---|
| Brake discs | Deformation and runout | Replacement or grooving |
| Oxygen sensors | Reduced efficiency | Checking readings with a scanner |
| Spark plugs | Electrode wear | Replacement (for gasoline internal combustion engines) |
| Particulate filter | Soot clogged | Flushing or replacement |
Checking the condition of the drive gears in the transfer case is also important, as wear on the gears can lead to noise when driving in a straight line and poor directional stability.
βοΈ Checklist before the 4th maintenance
Don't forget about the condition of the interior. The seats, steering wheel and pedals may show signs of wear after 4 years of active use. If you are planning to sell your car, cleaning up the interior will significantly increase its liquidity.
β οΈ Attention: Changing the oil in the DSG box at a mileage of 120,000 km is a critical procedure that prevents failure of mechatronics costing more than 100,000 rubles.
Regular and high-quality maintenance is the key to a long and trouble-free life for your SUV. Donβt skimp on consumables and trust your car only to certified specialists.
