Owning a diesel crossover Skoda Kodiaq It requires special attention to the engine lubrication system. Diesel powertrains, especially families EA288 evoThey generate more soot and combustion products compared to gasoline counterparts. This puts an increased strain on the filter element, which must hold the smallest particles capable of destroying the oil pump or clogging the turbine's oil channels.
Many owners mistakenly believe that the interval of oil and filter change can be extended to 30,000 kilometers, following the LongLife system. However, for Russian operating conditions, taking into account the quality of fuel and urban traffic, this approach is unacceptable. Timely replacement oil filter It is a critical procedure for preserving the turbocharger and piston group life.
In this article, we will discuss in detail which filters are suitable for different modifications. KodiaqHow to properly carry out the replacement procedure and what errors mechanics make when servicing diesel engines. You will learn why cheap analogues can cause expensive repairs and how to distinguish the original part from the fake.
Design features of the diesel engine filtration system
Diesel versions Skoda Kodiaq equipped with engines of 2.0 liters (engine codes) DKBA, DHMA, DQXA and others. These motors use a filtration system integrated into a plastic case that is fixed directly to the cylinder block. This solution differs from the classic barrels, where the filter changes as a separate metal element.
The plastic case of the filter has a built-in oil pressure sensor that transmits a signal to the electronic control unit. When the filter clogs, the pressure drops and the system can limit the engine power or shut it down for protection. That is why the use of a poor-quality filter with poor throughput is unacceptable. It is important to note that diesel versions are often installed. fine filter I'm packing gaskets.
The design provides for the presence of a reverse valve, which prevents oil from draining from the system when the engine stops. If this valve in the new filter is not working correctly, when starting a cold engine, the turbine is oil starving in the first seconds. This is the main reason for the premature failure of the turbocharger on cars Skoda.
Original parts and high-quality analogues: what to choose?
When selecting consumables, owners often face a dilemma: overpay for the original or save on a branded analogue. For diesel. Kodiaq The original filter has an article 04L 115 562 (or similar modifications depending on the year of release). The original part undergoes rigorous factory tests for rupture pressure and filtration efficiency.
However, the market offers decent alternatives that are not inferior to the original in characteristics. Among the proven manufacturers should be highlighted Mann-Filter, Hengst and Mahle. These brands are often suppliers to the Volkswagen Groupβs conveyor belt, so their products have identical parameters. The main thing is to make sure that there are no fakes, since the market of filter elements is saturated with counterfeit.
- π‘οΈ Mann-Filter Article W 712/94 is a standard of quality, often superior to the original in paper density.
- π‘οΈ Hengst (H100W02) - German quality, excellent resistance to high temperatures.
- π‘οΈ Mahle (Oc 1196) - a reliable filter with high-quality compression of the body.
It is not recommended to buy filters of unknown Chinese brands or products labeled βfor all diesel enginesβ. Incorrect geometry of gaskets can lead to oil leaks under pressure, which is dangerous by fire in the engine compartment.
Replacement Package: What else to buy
Replacement of oil filter on diesel Kodiaq It is not limited to installing a new cartridge. For quality maintenance, all sealing elements must be replaced. The filter is usually complete with a set of gaskets, but often it is incomplete or poor quality. It is recommended to purchase a separate repair kit seals.
A critically important element is the laying of the oil pallet drain plug. The copper washer is deformed after the first use and loses its sealing properties. Repeated use of such a washer often leads to oil leakage after a trip. Also, do not forget to check the condition of the sealing ring of the filter housing.
βοΈ Necessary consumables
Some owners ignore the need to replace the oil pressure sensor gasket located in the filter housing. If the seal is old, it can leak a couple thousand kilometers after being replaced, creating a dirty trail on the engine. This looks unaesthetic and can lead to corrosion of the sensor contacts.
Please note that the volume of the diesel engine oil system 2.0 TDI It is about 5-5.5 liters (depending on the type of filtration and the availability of an oil cooling system). When buying oil, always take a canister with a margin to be able to add the level in the future.
β οΈ Warning: Never use a sealant instead of a filter cover! This will damage the plastic case during subsequent disassembly and expensive repairs.
Step-by-step instructions for replacing the filter yourself
Filter replacement procedure Skoda Kodiaq With a diesel engine, no complex special equipment is required, but access to the unit may be limited. It is best to work on a lift or pit to ensure free access to the bottom of the engine. The car should be plugged and cooled to avoid burning with hot oil.
First, you need to unscrew the drain plug of the pallet and drain the old oil. After that, you can move to the filter body. It is located on the top of the engine, closer to the passenger side. Open the hood, remove the plastic decorative engine casing if it interferes with access to the filter cover.
- Every 7-8 thousand km
- Every 10-12 thousand km
- Every 15,000. km (LongLife)
- Only by sensor signal
The cover of the filter body is unscrewed using a special remover or a large hexagon (depending on the year of release). Unscrew it carefully, as there is residual oil inside, which will pour out. Put a liquid-collection tank in. Remove the old filter cartridge.
Before installing a new filter, be sure to clean the seat on the lid from dirt and remnants of old oil. Check that the old rubber gasket does not stick to the lid and does not remain inside the case. Install a new cartridge, lubricate the sealing rings with new oil for better tightness.
Twisting the filter cover with the recommended tightening moment. This value is usually about 25 Nm. Excessive puffing can lead to a crack in the plastic cover, which will require its replacement. After assembly, pour new oil and start the engine, checking for no leakage.
Common mistakes when replacing
Error 1: Plastic cover (crack) is pulled. Mistake 2: Forgot to remove the old gasket (oil flows). Error 3: Not replacing the copper washer cork (leaking from under the pallet). Mistake 4: Low-level oil (low-grade).
Diagnosis of problems and signs of filter clogging
To determine the clogging of the oil filter can be not only according to the regulations of the maintenance, but also by indirect signs of engine operation. If an oil pressure lamp is lit on the dashboard or a warning signal is sounded, this may indicate that the filter does not allow oil to pass in the desired volume. In diesel engines, this is often accompanied by a decrease in power.
Another sign of filter problems is the noise of the hydropushers or the timing system circuit at cold start. If you hear a metal knock in the first seconds of the engine, it is possible that the oil does not reach the lubrication zone due to a clogged filter or an inoperable return valve. In this case, you need to immediately shut down the engine and conduct a diagnosis.
- π¨ Error appears
P0087(low fuel system pressure) β may be indirectly related to the overall state of the lubrication and operation of the turbine. - π¨ Increased oil consumption β if the filter lets dirt through, it accelerates wear on the rings and turbines.
- π¨ Smoke from the exhaust pipe is a sign of engine wear due to poor lubrication.
It is important to understand that a modern diesel engine EA288 Very sensitive to the quality of the lubricant. Any deviations in oil pressure can lead to bullying in the cylinders or the destruction of the turbine bearings. Therefore, at the slightest suspicion of problems with filtration, it is necessary to carry out an unscheduled replacement.
β οΈ Warning: If the oil pressure lamp catches fire while driving, stop immediately and turn off the engine. Riding with a burning oil pressure lamp on a diesel engine Kodiaq It can lead to a wedge of the engine in 30-60 seconds.
Maintenance specifics for LongLife systems and replacement intervals
Plant programme LongLife It involves an interval of oil change up to 30,000 km or 2 years. However, for diesel engines operating in Russia, this regime is disastrous. Diesel oil accumulates soot faster than gasoline oil, and the filter simply cannot cope with the amount of pollution by the end of a large interval.
Experts and experienced owners Skoda Kodiaq It is recommended to transfer the car to fixed maintenance mode. This means that you set the interval of oil and filter change, ignoring the readings of the onboard computer. The optimal interval for a diesel engine - 7,000 β 8,000 km mileage
When using LongLife mode, the monitoring system may not take into account the real state of the fuel and engine operating modes. Electronics counts operating times and revs, but does not analyze fuel quality or frequent short-distance travel when the engine is not warming up. This leads to the accumulation of condensate and soot in the oil.
Fixed-mode transfers often require resetting service intervals through a diagnostic scanner or specialized software. This is a simple procedure that will extend the life of the engine by tens of thousands of kilometers. You should not save on oil and filters, as the cost of repairing a turbine or engine will many times exceed the cost of frequent replacements.
Always write down the mileage and date of oil change in a service book or phone notes. This will help you to track your actual service history and avoid errors when you replace it next.
It is also worth considering that at short intervals of replacement, you can use oil with tolerances of VW 507.00, but with less viscosity if the engine is new. For engines with a mileage of more than 150,000 km, it is recommended to use oil with slightly higher viscosity to compensate for the wear of gaps.
The influence of fuel quality on filter life
The quality of diesel fuel directly affects the life of the oil filter. At low-level gas stations, water, sulfur and mechanical impurities can enter the fuel. Water, getting into the crankcase, forms an emulsion, which clogs the filter pores and reduces its effectiveness. Sulfur contributes to the formation of acids that accelerate the oxidation of oil.
Diesel engines Skoda Kodiaq They are equipped with a complex Common Rail injection system, which is extremely sensitive to the purity of the fuel. If the rough cleaning filter (in the tank) does not cope, the dirt enters the fuel system, and the wear products of the nozzles and TNVD enter the crankcase back through the crankcase ventilation system. This puts a huge strain on the oil filter.
- π Use only proven gas stations of federal networks with a good reputation.
- π Keep an eye on the condition of the diesel engine fuel filter - its replacement should occur more often than the regulations.
- π In winter, use antigels and additives to prevent the formation of paraffins that can clog the filter.
If you notice that the oil filter changes too often or clogs up quickly, itβs worth checking the fuel system for excess soot. Perhaps the problem isn't the oil, but faulty injectors or the EGR system, which throws soot into the intake.
Regularly replacing the oil filter at intervals of 8,000 km is the cheapest way to extend the life of the Kodiaq diesel engine and turbine.
FAQ: Answers to frequently asked questions from owners
Can I use a filter from other VAG models?
Yes, filters from other Volkswagen Group models with 2.0 TDI engines (e.g. Passat B8, Audi A4, Seat Ateca) are often suitable for landing sizes. However, before buying, be sure to check the article and make sure that the filter parameters (valve opening pressure, filtration area) meet the requirements of your engine.
Do I need to change the filter cover separately?
It is recommended to change it always. Even if it seems whole, rubber loses its elasticity over time. The filter is often complete with a gasket, but if it is not available or it is of low quality, buy a separate remake. Leaking oil from under the lid is a frequent problem when saving on gaskets.
How often should the fuel filter on a Kodiaq diesel be changed?
The recommended interval for a diesel engine fuel filter is 60,000 km. However, when operating in Russian conditions, it is better to change it every 40,000-50,000 km. A clogged fuel filter can damage the high pressure fuel pump (HPPP).
Can I add oil from another brand?
It is allowed to add oil of another brand if it has the same manufacturer tolerances (VW 507.00 for diesels) and similar viscosity. However, it is best to avoid frequent mixing of oils from different manufacturers, as their additive packages may not be compatible.
What to do if the oil pressure lamp lights up after changing the filter?
Turn off the engine immediately. Check the oil level (you may have overflowed or under-supplied). Check the place of installation of the filter for leaks. If there are no leaks, the problem may be incorrect installation of the return valve or defect of the filter itself. Check the oil pressure sensor as well.
