Nissan Qashqai engine number: where is it located, how to decipher and check

Engine number Nissan Qashqai is a unique identifier that is required to register with the traffic police, purchase spare parts, check the car’s history or diagnose faults. However, finding it is not as easy as it seems: the location depends on the generation of the crossover (J10, J11 or J12), engine type (HR16DE, MR20DD, K9K etc.) and even the year of manufacture. In this article, we will look at where exactly to look for the number, how to read it correctly (including “blind” zones), and why the data from the plate under the hood may not coincide with the real number on the block.

We will pay special attention common mistakes: for example, many people confuse the engine number with VIN code or body number, and some “craftsmen” specifically remove the markings before selling. We will show you how to distinguish the original engraving from the interrupted one, and what to do if the number is erased or unreadable. At the end of the article - current table of correspondence between engine numbers and models Qashqai for Russia and Europe, as well as answers to frequently asked questions about checking through the traffic police databases and Nissan.

Where is the engine number on a Nissan Qashqai: step-by-step instructions

The location of the number depends on the engine type and generation of the crossover. On Qashqai J10 (2007–2013) and J11 (2014–2021) with gasoline engines (HR16DE, MR20DD) the number is usually stamped on the cylinder block right (in the direction of travel), next to the gearbox. On diesel K9K (1.5 dCi) and R9M (1.6 dCi) markings can be hidden under pipes or protection.

On Qashqai J12 (from 2021) the manufacturer has moved the number to a more prominent place - left side of the block (from the radiator side), but it is still difficult to see without a mirror. To avoid wasting time searching, follow the algorithm:

• 🔧 Gasoline engines (HR16DE, MR20DD): the number is stamped on the flat area of the cylinder block on the right (interior side). It is often closed by the cooling system pipe - it must be carefully removed.
• ⚙️ Diesel engines (K9K, R9M): Look for the marking on the front of the block, below the oil filter. You may need to remove the protection or use a flashlight.
• 🔍 Turbocharged versions (MR16DDT): The number is located on the back wall of the unit, closer to the box. Access is difficult - you will have to lie under the car or use an endoscope.

If the number is not visible from the top, try looking from below (from a pit or lift). On some copies the markings are duplicated on metal plate under the hood (next to the VIN code), but this is not the official engine number, but only reference information for services.

What the engine number looks like: photos and examples

Original engine number Nissan Qashqai is a combination of 7–9 characters, where the first 2–3 letters indicate the motor series (for example, HR16 for HR16DE), and the rest are a unique production code. Characters are knocked out dot engraving (not with a deep cutter!), without burrs or uneven edges.

Examples of real numbers:

• HR16DE-1234567 — petrol 1.6 l (J10/J11).
• MR20DD-89ABC12 — petrol 2.0 l (J11).
• K9K-7654321 — diesel 1.5 l (J10).

Please note engraving quality:

• ✅ Original: The symbols are even, of the same depth, without traces of stripping.
• ❌ Interrupted number: uneven edges, different font depths, sanding marks all around.

Below are photographs of typical locations (clickable for enlarged views):

On petrol HR16DE, the number is located on the right side of the block, under the cooling pipe. On diesel K9Ks - on the front part of the block, below the oil filter. Turbocharged MR16DDTs have markings on the rear wall, which can only be accessed from below.

⚠️ Attention: Found on the market Qashqai with “gray” engines (for example, counterfeit K9K from China), where the number is stamped crookedly or does not correspond to the database Nissan. If the symbols look suspicious, check the vehicle history through VIN.

How to decipher the engine number of a Nissan Qashqai

Engine number Nissan consists of two parts:

1. Prefix (motor series): 2–4 letters/numbers identifying the model (for example, HR16 - series HR, volume 1.6 l).
2. Unique code: 5–7 characters - production number, by which you can determine the year of manufacture and plant.

Decoding prefixes for Qashqai:

Prefix	Engine model	Type	Volume	Years of installation
HR16DE	HR16DE	Gasoline	1.6 l	2007–2021
MR20DD	MR20DD	Gasoline	2.0 l	2010–2021
K9K	K9K 732/734	Diesel	1.5 l	2007–2017
R9M	R9M 404/409	Diesel	1.6 l	2014–2021
MR16DDT	MR16DDT	Gasoline turbo	1.6 l	2017–present

The last characters of the unique code may contain information about:

• 📅 Year of manufacture: for example, letter A — 2010, B — 2011, etc.
• 🏭 Manufacturer: 1 — Japan, 2 — Great Britain, 9 - Russia.
• 🔧 Modifications: additional letters/numbers after the main code (for example, HR16DE-123456A, where A - version for Europe).

How to check the engine number using the traffic police and Nissan databases

Checking the engine number through official databases helps to identify broken markings, theft or mismatch of documents. Here are the working methods:

1. Check through the traffic police (for Russia)

Use car history check service:

1. Enter VIN or license plate number.
2. In the “PTS Data” section, compare the engine number with the one stamped on the block.
3. If the data does not match, the car has a suspicious history.

2. Request to Nissan Russia

Official dealers can check the number using their internal database. To do this:

• Contact the service center with VIN and engine number.
• Request compliance report (paid, ~1,500 rub.).
• The report will indicate the production date of the engine and the model of the car for which it was intended.

3. Online services (CarVertical, Autocheck)

Paid services like CarVertical or Autocheck aggregate data from European databases. They will show:

• 🔄 Mileage history (if the engine number has changed).
• 🚨 Facts of theft or accident.
• 🔧 Service history (if the engine was officially replaced).

⚠️ Attention: If an inspection reveals that the engine is 2+ years older than the vehicle, this may indicate contract motor (not always legal). The PTS must contain a note about the replacement.

What to do if the engine number is erased or unreadable

Abrasion or corrosion of the license plate is a common problem, especially on diesel engines. Qashqai (due to its close location to the oil filter). Here's what you can do:

1. Cleaning and restoration

If the number is barely visible:

• 🧹 Clean the area soft brush (no metal!) and WD-40.
• 🔦 Light it up oblique light — symbols will become more visible.
• 📸 Take a photo at close range and enlarge it on your computer.

2. Chemical manifestation

For heavily corroded plates, use metal etching reagent (For example, Gun Blue):

1. Apply the reagent to the numbered area.
2. Wait 5-10 minutes - the symbols will appear dark.
3. Rinse with water and take a photo.

3. Contacting an expert organization

If the number is not readable at all, you will need forensic examination (cost ~5,000 rub.). Experts use:

• 🔬 Microscope for analyzing microcracks.
• 📡 Ultrasound scanning (to identify broken characters).
• 🖼️ Comparison with the base Nissan by VIN.

Important: if the number is erased intentionally (traces of grinding, welding), the car cannot be registered with the traffic police until the marking is restored.

Frequently asked questions about the Nissan Qashqai engine number

Is it possible to drive if the engine number does not match the title?

No. The discrepancy between the number on the block and the data in the PTS is considered design inconsistency (Article 12.1 of the Administrative Code). The car will not pass inspection, and when stopped by the traffic police, the license plates may be confiscated. To legalize an engine replacement, you need to:

1. Receive a certificate from the service center regarding replacement.
2. Pass an examination at NIIAT.
3. Make changes to the PTS through the traffic police.

How to distinguish the original number from the interrupted one?

Signs of a broken number:

• Symbols of different depths or with “tails”.
• Grinding or welding marks around the area.
• The number is knocked out deep (original - dot engraving).
• Paint or sealant on the area (an attempt to hide marks).

To check, use a magnifying glass and a flashlight - the original symbols have microscopic burrs from the factory stamp.

Where else can I find the engine number other than the block?

Duplicate information may be:

• On metal plate under the hood (next to the VIN).
• B service book (if the car was serviced by an official dealer).
• On gearbox (sometimes part of the number is duplicated).

But this data are not official — for the traffic police, only the number on the block is important!

What to do if the seller refuses to show the engine number when purchasing?

This red flag. Possible reasons:

• The engine is stolen or counterfeit.
• The number has been interrupted (for example, after an accident).
• The car is pledged (traffic police restrictions).

Refuse the deal or demand:

1. Provide a photo of the number (from your side, check through CarVertical).
2. Carry out an inspection at a service station with a lift.
3. Conclude an agreement with a return condition if any discrepancies are found.

Is it possible to restore the engine number yourself?

No. Any interference with labeling (even “restoration” with chemistry) is equivalent to counterfeit (Article 326 of the Criminal Code of the Russian Federation). If the number is erased, the only legal way is examination by an accredited organization (for example, Research Center "Avtoexpert").
