• 🔍 On the platform under the thermostat (you will have to remove the air filter). Characteristic for 1.6 MPI (CFNA, CWVA).
• 🛠️ On the clutch housing (requires access from below or a lift). Relevant for 2.0 TDI (CFFB, CRTD).
• 📌 Under the oil filter (the most inconvenient option, requires draining the oil). Found on rare versions 1.2 TSI (CZDA).

Below is a table with exact coordinates for each modification:

Engine model	Volume/Type	Room location	Do I need to remove parts?
CZDA, CZEA	1.4 TSI (140–150 hp)	In front of the cylinder block, under the pipe	No (mirror is enough)
CFNA, CWVA	1.6 MPI (90–110 hp)	Area under the thermostat	Yes (remove air filter)
CJS, CJX	1.8 TSI (180–192 hp)	Cylinder block, left side	No (visible from the pit)
CFFB, CRTD	2.0 TDI (150–184 hp)	Clutch housing or block on the right	Yes (lift/pit)

⚠️ Attention: On some Octavia A7 after 2017 the engine number may be duplicated on badge under the hood (next to VIN). But this is not the official engine number, but only a service marking for assembly! It is not suitable for the traffic police and insurance companies.

How to read the engine number: decoding by symbols

Engine number on Škoda Octavia A7 consists of 14–17 characters (letters and numbers) and carries encrypted information about the model, year of manufacture and even country of assembly. It is deciphered according to the following principle:

1. First 3–4 characters - engine model code (for example, CZDA = 1.4 TSI 140 hp).
2. Next 6–8 characters — serial number of the unit (unique for each motor).
3. Last 2–3 characters - check digits or plant code (for example, VW for Volkswagen Group).

Example of number decoding CZDA1234567VW:

• 🔹 CZDA — engine model (1.4 TSI, 140 hp).
• 🔹 1234567 — serial number (to check for theft).
• 🔹 VW - manufacturer (Volkswagen Group, Czech Republic/Germany).

⚠️ Attention: If the engine number contains Latin letter "O" (not the number "0"), this is a sign of a fake! Original numbers Škoda never contain the letters "O", "I" or "Q" - they can easily be confused with numbers.

How to distinguish the original number from the interrupted one?

A broken number often has jagged character edges, putty marks, or mismatched fonts. Original numbers are applied with a laser or impact method - touching with a finger does not feel the protrusions.

Step-by-step instructions: how to find and read the engine number

In order not to waste time on useless searches, follow this algorithm (the instructions are universal for everyone Octavia A7, but taking into account the nuances for each motor):

1. Remove the decorative engine cover (if equipped).
2. Shine a flashlight on front part of the cylinder block (from the radiator side).
3. The number is stamped on a small area under the cooling system pipe. Use a mirror for convenience.

For 1.6 MPI engines:

1. Disconnect the mass air flow sensor (MAF) connector.
2. Remove the air filter housing (unscrew the 4 bolts).
3. Under the thermostat (to the right of the block) you will find a pad with a number.

Common mistakes when searching and reading engine numbers

Even experienced car owners make mistakes that lead to problems with registration or purchasing spare parts. Here are the most common:

1. They confuse the engine number with the gearbox number. On Octavia A7 the gearbox has a separate marking (usually on the right side of the crankcase). It is not suitable for documents!
2. Read partial number. Sometimes the last digit is hidden under the pipe and is easy to miss.
3. Ignore duplicate tags. On some engines the number is duplicated on gas distribution mechanism (for example, on 1.8 TSI). If the main mark is erased, check the take.

📌 Tip: Always photograph the engine number from different angles and in good lighting. This will help avoid mistakes when filling out documents.

• 🔗 8th character — body type (for Octavia A7 this is usually 5 — liftback or 6 - station wagon).
• 🔗 10th character - year of manufacture (for example, E = 2014, F = 2015).

Example VIN for Octavia A7 1.8 TSI 2016:

TMBJJ7NE6G0123456

• E6 — 2016.

• 🔧 Replacing the engine after an accident (legally, if registered through the traffic police).
• 🚨 Replacing the engine after theft (illegal, check the history!).
