Nissan X-Trail oil filter: where is it located and how to get to it?

Changing the oil in Nissan X-Trail is a standard procedure, but many owners face difficulties when finding an oil filter. Its location depends on the crossover generation (T30, T31, T32), engine type (gasoline or diesel) and even the year of manufacture. In this article you will find exact filter coordinates with photos, comparison of access on different motors and practical tips on how to simplify replacement without a pit or lift.

Feature X-Trail — the filter is not always located in the classic place next to the pan. For example, on diesel versions with an engine M9R it may be hidden behind protection or require removal of the pipes. And on gasoline MR20DD (2.0 l) and QR25DE (2.5 l) access is complicated by hanging elements. We will look at all the options, including rare cases when the filter is installed in atypical place under the hood - this occurs on restyled models of 2017+.

1. Location of the oil filter by generation of Nissan X-Trail

Crossover generation is a key factor in determining where to look for a filter. Below is the data for the most common versions on the Russian market:

Generation	Years of manufacture	Engine	Filter location	Access Features
T30	2001–2007	QR20DE (2.0), QR25DE (2.5)	To the right of the pallet (in the direction of travel)	Requires removal of crankcase protection
T31	2007–2013	MR20DE (2.0), QR25DE (2.5), M9R (2.0 diesel)	On gasoline - under the generator; on a diesel engine - behind the right drive shaft	On a diesel engine, the intercooler pipe often gets in the way
T32	2013–2022	MR20DD (2.0), QR25DE (2.5), R9M (1.6 diesel)	On gasoline - to the left of the sump; on a diesel engine - above the sump, closer to the passenger compartment	On MR20DD the filter can be covered with a plastic cover
T33	2021–present	KR25DDT (2.5 turbo)	Under the hood, to the right of the engine	Access from above, but requires removal of the duct

On X-Trail T32 with engine MR20DD (2014–2020) filter is often confused with oil module - a plastic case into which a replaceable filter element is inserted. This is not a classic metal filter, but a collapsible design with a cover with 3-4 bolts. Nissan used this solution to simplify maintenance, but it requires careful assembly (it is important not to overtighten the bolts!).

2. Where to look for a filter on petrol Nissan X-Trail?

On gasoline engines X-Trail The filter is usually located at the bottom of the engine, but its exact location depends on the size and type of internal combustion engine:

• 🔧 Engines QR20DE/QR25DE (T30/T31): the filter is located to the right of the oil pan (in the direction of travel of the car). To see it, you need to remove the metal crankcase protection. The filter has a classic cylindrical shape with threads and gasket.
• 🔧 Engine MR20DE (T31): The filter is hidden under the generator. Access to it is complicated by attachments - it is often necessary to remove the generator belt or unscrew its bracket.
• 🔧 Engines MR20DD/QR25DE (T32): the filter is shifted to the left of the pan. On MR20DD This is a plastic module with a cover for 3 bolts (key size - 10 mm), on QR25DE - traditional metal filter.

On X-Trail T32 with motor MR20DD (2.0 l, 144 hp) oil filter integrated into oil module - plastic housing with a filter element inside. To replace it:

1. Remove the plastic cover (3 bolts on 10 mm).
2. Remove the old filter element and o-rings.
3. Install a new element (part number of the original - 15208-4M50A) and assemble the module in reverse order.

On petrol versions the filter is always located below the oil level in the pan, so when replacing it, some of the oil will leak out. To minimize losses, it is recommended to first drain the oil through the pan plug and then change the filter.

3. Features of the location of the filter on diesel X-Trail

Diesel versions Nissan X-Trail (engines M9R 2.0 l and R9M 1.6 l) have a fundamentally different arrangement of the oil filter. He is located above the pallet, closer to the cabin, and often covered with hanging elements. Main difficulties:

• 🔧 On M9R (T31) the filter is hidden behind the right drive shaft. To get to it, you need to remove the protection and unscrew the shaft mount (you will need a wrench 14 mm).
• 🔧 On R9M (T32) the filter is located above the pan, but access to it is blocked by the intercooler pipe. You will have to loosen the clamps and move the pipe to the side.
• 🔧 On both engines the filter has increased size (height ~15 cm) and is equipped with a check valve to prevent oil drainage when the engine is stopped.

On diesel X-Trail oil filter is often confused with fuel filter, which is located nearby (on M9R - to the left of the engine, on R9M - under the hood). To avoid mistakes, focus on:

• 🔹 The oil filter always has a metal housing with threads M20x1.5.
• 🔹 Plastic fuel filter, with quick-release chips.
• 🔹 There is a marking on the oil filter cover OIL FILTER or Nissan logo.

How to distinguish an oil filter from a fuel filter on a diesel X-Trail?

On diesel engines M9R And R9M The fuel filter is located above the oil filter and has a plastic housing with supply pipes. The oil filter is always metal, with a hexagon wrench (size 36 mm for M9R or 27 mm for R9M).

When replacing a filter on a diesel engine, be sure to check the condition sealing washer on the drain plug of the pan. On M9R it is often deformed due to the high temperature of the oil, which leads to leaks. The original washer has an article number 11026-01M02.

4. Step-by-step instructions: how to get to the filter without a hole

Not everyone has access to a lift or inspection hole, but replacing the oil filter with X-Trail It can also be done on a flat surface. The main thing is to jack up the car correctly and provide yourself with room to maneuver. Below are universal instructions for gasoline models (on diesel engines the process is more complicated due to attachments).

Jack up the front of the car and place jack stands on the rear wheels.

Remove the crankcase protection (4–6 bolts per 10 mm)

Place a container under the drain plug and unscrew it (the key is on 14 mm)

Wait until the oil is completely drained (10–15 minutes)

Unscrew the filter counterclockwise (use a puller or rubber gloves) -->

To unscrew the filter without a puller, you can use:

• 🔧 Belt or rope: place a loop over the filter housing and pull sharply (the method works if the filter is not “stuck”).
• 🔧 Screwdriver and hammer: pierce the filter housing with a screwdriver and unscrew it like a lever (this method is only suitable for metal filters!).
• 🔧 Rubberized gloves: If the filter is not too tight, you can unscrew it by hand.

On X-Trail T32 with plastic oil module (MR20DD) the process is simplified:

1. Drain the oil through the pan plug.
2. Unscrew the 3 module cover bolts (key on 10 mm).
3. Remove the old filter element and o-rings.
4. Install a new element (original - 15208-4M50A) and assemble the module.

After installing a new filter (or assembling a module) necessarily:

• 🔹 Lubricate the O-ring with new oil.
• 🔹 Tighten the filter by hand until it stops, then tighten it 3/4 of a turn (do not overtighten!).
• 🔹 Fill the oil, start the engine and check the leaks.

5. Common mistakes when searching and replacing a filter

Even experienced car owners sometimes make mistakes that lead to oil leaks or engine damage. Here are the most common:

⚠️ Attention: On X-Trail T32 with engine MR20DD Do not use pullers for metal filters on a plastic oil module! This will lead to housing cracks and oil leakage. Unscrew the module cover only with a key 10 mm.

• 🚨 Mixed up filters: on diesel versions it is easy to confuse the oil filter with the fuel filter. The consequences are fuel getting into the oil or vice versa, which leads to engine jam.
• 🚨 The filter was not tightened or tightened enough: Under-tightening will cause leakage, over-tightening will damage the threads or body. Optimal torque: hand tightening + 3/4 turn.
• 🚨 Forgot to lubricate the O-ring: dry rubber will stick to the seat, and the next time you replace the filter it will be difficult to unscrew.
• 🚨 Used the wrong filter: for example, they installed a filter from QR25DE on MR20DD. This will lead to oil starvation due to the difference in bandwidth.

On diesel X-Trail with engine M9R often forget to check check valve status in the filter. If it is faulty, oil will drain into the sump when the engine stops, which will lead to dry start and accelerated wear of the turbine. Signs of a problem:

• Long operation of the oil lamp after startup.
• Knock of hydraulic compensators in the first seconds after start.
• Increased oil consumption (more than 1 liter per 10,000 km).

Another common mistake is ignoring oil stains after replacement. If after 1-2 days oil drops appear under the car, check:

• 🔹 Tighten the drain plug (torque - 30–40 Nm).
• 🔹 Condition of the filter sealing ring.
• 🔹 Integrity of the filter housing (on diesel engines it can crack due to vibrations).

6. Articles and analogues of oil filters for X-Trail

Using a low-quality or unsuitable filter is one of the main reasons for premature engine wear. Below is a table of original articles and proven analogues for different engines Nissan X-Trail:

Engine	Original article	Analogs (brand + article)	Notes
QR20DE/QR25DE (T30/T31)	15208-65F0A	Mann W712/73 Bosch 0 451 103 316 Framm PH7317	Filter with check valve
MR20DE (T31)	15208-4M500	Mann W712/94 Mahle OC506 Sakura C-1028	Filter height - 90 mm
MR20DD (T32)	15208-4M50A (element) 15208-4M51A (module)	Mann W713/90 (element) Blue Print ADM52301 (module)	Module includes 2 O-rings
M9R (2.0 diesel)	15208-4M50E	Mann W713/85 Hengst E299L Filtron OP643/3	Filter with increased capacity
R9M (1.6 diesel)	15208-BM40A	Mann W713/95 Bosch 1 457 429 637 Knecht OC630	Requires replacement every 15,000 km

When choosing an analogue, pay attention to:

• 🔹 Presence of a check valve (critical for diesel and turbocharged gasoline engines).
• 🔹 Filter sizes: Height, diameter and thread pitch must match the original.
• 🔹 O-ring quality: It should be elastic, without cracks.

On X-Trail T32 with plastic oil module (MR20DD) often save on O-rings by reusing them. This leads to oil leaks and air entering the system. Always change your rings when replacing the filter element (article - 15218-4M50A).

7. Pro tips: how to make filter replacement easier

Experienced craftsmen know several tricks that save time and nerves when replacing the oil filter with Nissan X-Trail:

• 🔧 Warm up the engine before draining the oil: warm oil flows faster and the filter is easier to unscrew. Optimal temperature - 40–50°C (do not overheat to avoid getting burned!).
• 🔧 Use a chain puller for “stuck” filters. It is more reliable than cup pullers and does not slip.
• 🔧 Apply marks onto the filter housing and seat before unscrewing. This will help you install the new filter correctly (especially important for diesel engines, where the filter has an asymmetrical shape).
• 🔧 Check the drain plug magnet: metal particles accumulate on it - an indicator of engine wear. If there are a lot of chips, diagnostics are required.

On diesel X-Trail with engine M9R To make access to the filter easier, you can:

1. Remove the right front wheel and fender liner.
2. Loosen the clamps and move the intercooler pipe to the side.
3. Use the wrench extension to unscrew the filter from the bottom.

If the filter is stuck and cannot be unscrewed, do not use excessive force - this may damage the fitting on the engine block. In such cases:

• Treat the joint penetrating lubricant (For example, WD-40) and wait 10–15 minutes.
• Use ratchet pullerto avoid jerking.
• As a last resort, carefully drill the filter housing and unscrew it using a screwdriver.

8. When to change the oil filter: regulations and signs of wear

Nissan recommends replacing the oil filter every 15,000 km or once a year (whichever comes first). However, this interval is only relevant for ideal conditions operation:

• 🔹 High quality pure oil (e.g. Nissan Strong Save X 5W-40).
• 🔹 Calm driving style (without sudden accelerations and braking).
• 🔹 Absence of extreme temperatures (frost below -20°C or the heat is higher +35°C).

In real conditions (city traffic jams, frequent cold starts, dusty roads), the filter clogs faster. Signs that it's time to change it:

• 🔹 Extended interval between oil changes (more than 10,000 km).
• 🔹 Increased oil consumption (more than 500 ml per 5,000 km).
• 🔹 Dirty oil on the dipstick (dark color, visible particles).
• 🔹 Knock of hydraulic compensators after starting the engine.
• 🔹 Oil pressure light comes on at idle speed.

On diesel X-Trail The filter requires more frequent replacement due to:

• 🔹 Increased soot load (especially during urban use).
• 🔹 Higher oil temperature (Diesels run hotter than gasoline engines).
• 🔹 Availability of a turbinewhich requires clean oil to lubricate the bearings.

⚠️ Attention: On X-Trail T32 with engine R9M (1.6 diesel) oil filter has reduced resource due to its compact size. Change it every 10,000 km, even if the oil is still “fresh”.

If you are using long lasting oil (For example, Mobil 1 Extended Performance), this does not mean that the filter can also be changed less frequently. The filter element becomes clogged with mechanical particles that the oil cannot dissolve, so its resource is limited 10–15,000 km regardless of oil type.

FAQ: Frequently asked questions about the Nissan X-Trail oil filter

Is it possible to change the oil filter without changing the oil?

Technically yes, but this not recommended. Remains in the filter up to 200–300 ml old oil, which will mix with the new one and worsen its properties. An exception is if the filter is damaged (for example, during installation) and requires urgent replacement. In this case, after installing the new filter, you should drive 500–1000 km and change the oil completely.

Which filter is better - original or analogue?

Genuine Nissan filters are manufactured by Mann or Hengst and are of high quality. However, their analogues from the same brands (for example, Mann W712/94 instead of the original 15208-4M500) are not inferior in any way, but stand on 20–30% cheaper. The main thing is to avoid cheap no-name filters that may fall apart or fail to retain oil when the engine is stopped.

What happens if you don't change the oil filter?

A clogged filter leads to:

• 🔹 Oil starvation engine (the bypass valve opens and uncleaned oil enters the system).
• 🔹 Accelerated wear turbines, crankshaft and camshafts.
• 🔹 Increased oil consumption (due to stuck piston rings).
• 🔹 Rotation of liners (in critical cases).

On diesel engines M9R/R9M ignoring filter replacement also leads to clogging of oil channels in the block head and overheating.

Is it possible to wash the oil filter?

No, it's useless and dangerous. The filter element is made of special paper, which after washing loses its properties (the pores become clogged with dirt and the fiber structure is destroyed). In addition, particles of old oil remain in the filter, which, when mixed with new oil, worsen its performance. The only correct way is to replace it with a new filter.

Why does the oil pressure light come on after replacing the filter?

The reasons may be as follows:

• 🔹 Insufficient oil level (check the dipstick).
• 🔹 Faulty oil pump (especially if the lamp lights up at high speeds).
• 🔹 Air in the system (typical for diesel engines after replacing the filter; bleeding is required).
• 🔹 Filter defect (for example, the check valve does not work).
• 🔹 Clogged oil channels (engine flushing required).

If the lamp stays on longer 5–7 seconds after starting, turn it off immediately
