Finding the Powertrain Identification Number on a Vehicle Nissan Qashqai often causes difficulties for owners, especially if the car has significant mileage. Unlike European counterparts, where markings can be engraved in a visible place, Japanese manufacturers often hide this information in hard-to-reach areas. It is important to understand that knowing the exact location is necessary not only for selling, but also for obtaining insurance or passing a technical inspection.
Many car enthusiasts mistakenly believe that the engine number always duplicates the body number, but this is not the case. On modern crossovers Nissan a complex marking system is used, which includes the motor model index and a unique serial number. If you cannot find the numbers right away, do not panic and contact forensic experts - the problem can often be solved by a simple visual inspection using additional tools.
Main marking areas on the engine
On most modifications Nissan Qashqai first and second generation numbers are stamped directly on the cylinder block. However, access to this area is limited due to the tight layout of the engine compartment. You'll have to open the hood and take a close look at the front of the powertrain where the unit connects to the transmission. Often the markings are located at the bottom, closer to the subframe, which requires the use of a mirror and a flashlight.
Depending on the engine type (petrol or diesel), the location may vary slightly. On gasoline engines of the series HR16DE and MR20DE the number is often stamped on the back wall of the block, in the area where the flywheel is mounted. Diesel versions YD25DDTi are marked in the area where the high pressure fuel pump is attached. If you see dirt or oil stains, cleaning the surface will be a must for a successful search.

- π§Ό Prepare carburetor cleaner or solvent to remove oil film
- π‘ Lighting should be directed so that the shadows do not hide the deep notches of the numbers
β οΈ Warning: Do not attempt to remove engine or transmission mounts for better access without specialized equipment. You risk damaging the sensors or depressurizing the cooling system.
Features of search on petrol modifications HR16 and MR20
Gasoline engines HR16DE, installed on Nissan Qashqai with a volume of 1.6 liters, have a characteristic feature of the location of the room. It is located on the cylinder block, but is often covered by the generator bracket or cooling system pipes. You will have to carefully inspect the right side of the engine (if you look in the direction of travel), where the block joins the gearbox. Sometimes the number is visible only after removing the decorative plastic engine cover.
For series motors MR20DE (volume 2.0 liters) the situation is similar, but the numbers can be stamped on the protruding part of the block on the gearbox side. In some cases, the markings are located on a horizontal plane, which is easy to disguise with plaque.
If you do not find the number on the cylinder block, check the vehicle's technical documentation. The service book often contains information about the replacement of the unit, which can help with identification. Also pay attention to the VIN plate, where sometimes there is additional information about the type of power unit, although this is not a direct engine number.

- 2.0 Petrol (MR20)
- 1.5 Diesel (K9K)
- 2.0 Diesel (YD25)
Marking cleaning and visualization technology
Often the problem is not the absence of a number, but its complete unreadability due to corrosion or dirt. Cleaning surface requires care so as not to erase the numbers themselves. Use a soft wire brush and special chemicals. Do not use files or coarse sandpaper, as this may damage the metal structure and invalidate the license plate for the traffic police.
After mechanical cleaning, you can use contrasting paint or chalk to emphasize the relief of the numbers. Apply a small amount of the substance to the surface and carefully remove excess. This will allow you to see even the smallest notches that are not visible to the naked eye. This method is especially effective for older cars where the markings have worn off over time.
- π§΄Use a penetrating lubricant to remove old rust
- ποΈ Soft brass brush will not scratch the surface of the cylinder block
- πΈ Take a macro photo of the cleaned area for detailed examination on the screen
If the engine number is severely damaged by corrosion, it is better to contact professionals at a service station who have experience in restoring markings and can restore legibility without compromising the integrity of the metal.
Diesel units: nuances of YD25 and K9K markings
Diesel engines Nissan Qashqai, such as YD25DDTi and K9K, have their own peculiarities of room placement. On the motor YD25 (2.5 liter) markings are often located on the flywheel side of the cylinder block, under the heat shield. This area is exposed to high temperatures, which can lead to deformation of the metal or complete erasure of the numbers.
On a more compact diesel K9K (1.5 liter) number can be stamped on the gearbox housing or on a special plate attached to the block. In some cases, the manufacturer places duplicate markings on the generator bracket. It is important to check all possible places, since the design of a diesel unit is more bulky and requires a detailed inspection.
If you are the owner of a diesel version, pay attention to the condition of the fuel system. Diesel leaks often lead to the formation of soot, which completely hides the number. Cleaning in this case requires more aggressive means, but this must be done with care so as not to damage the rubber seals and sensors.

Relationship between engine number and VIN code and documents
It is important to understand the difference between the engine number and the vehicle's VIN. VIN - this is a unique identifier of the body, which is duplicated on the nameplate and in documents. The engine number is the identification number of a specific power unit. On modern cars Nissan These numbers may not match, especially if the engine was replaced under warranty or as a result of repair.
The documents (STS and PTS) indicate the engine number, which must correspond to the markings on the unit itself. If they do not match, this may result in refusal to register or re-register the vehicle. In such cases, it is necessary to provide documents confirming the legality of replacing the engine, for example, a purchase and sale agreement for the unit or a certificate of completion of work from the service center.
| Parameter | Description | Place in documents |
|---|---|---|
| VIN code | 17-digit body number | PTS, STS, nameplate on the rack |
| Engine number | Unit serial number | PTS, STS, on the cylinder block |
| Model index | Engine type (HR16, MR20) | PTS, plate under the hood |
| Release date | Month and year of construction | As part of the VIN code |
β οΈ Attention: If the engine number is not readable or does not match the documents, do not attempt to clear or restore it yourself. This may be considered document forgery, and you will have to prove your innocence in court.
What to do if the engine number is completely lost?
If the engine number is completely erased or missing, you must contact a specialized expert bureau for an examination. They can restore the number based on residual characteristics or issue a conclusion that the number is missing. With this conclusion, you can contact the traffic police for registration or deregistration. However, this process is long and requires a significant investment of time and money.
Problems with rust and marking corrosion
One of the most common problems of owners Nissan Qashqai is corrosion of the place where the number is stamped. In areas with an aggressive climate and frequent use of reagents, the metal quickly oxidizes. Rust can completely cover the numbers, making them unreadable. In such cases, simple cleaning does not help and a more in-depth approach is required.
Sometimes it helps to use chemical reagents that dissolve iron oxides without affecting the base metal. However, this requires a professional approach and precise adherence to dosages. Incorrect use of acid can lead to destruction of the cylinder block and the impossibility of further restoration of the number.
- π‘οΈ Use a rust converter to neutralize oxides
- π¬ Consider ultrasonic cleaning in the laboratory
- ποΈ In case of severe corrosion, contact marking restoration experts
Restoring the engine number is only possible if there are remaining numbers. If the metal is completely rotten, an official expert opinion will be required and the unit will be replaced with a similar one with a readable number.
Legal aspects and interaction with the traffic police
When passing a technical inspection or registering a car, traffic police inspectors must check the engine number. If it is not readable, you may be denied the procedure. In this case, you will need to undergo an examination at a specialized institution, which will issue an opinion on the condition of the number. This conclusion will be the basis for the inspector's decision.
It is important to note that recently the requirements for the readability of numbers have become more stringent. Even small abrasions can be a reason for refusal. Therefore, regular inspection and cleaning of the place where the number is stamped is not just a recommendation, but a necessity to avoid problems with the law. If you are planning to sell your car, make sure the engine number is in perfect condition.
If you are faced with a situation where the engine number has been altered or tampered with, this may result in criminal liability. Never try to change numbers or fake a number yourself. Use only official methods for restoring and documenting changes to the unit.
