Common problems when searching for an engine number and how to solve them

Owners Škoda Octavia A5 often encounter difficulties when finding the engine number. Here are the most common problems and how to solve them:

🔧 The number is hidden under dirt or oil: Clean the surface of the cylinder block with a solvent (such as 646) and a soft brush. Do not use metal tools as they may damage the markings.
🔍 The number is worn out or corroded: Try shining a flashlight on the area at an angle - this will help reveal the engraving marks. As a last resort, use chemical reagent for restoring numbers (sold in auto stores).
🚗 No access due to attachments: For engines 1.8 TSI and 2.0 TDI It may be necessary to remove the air filter or crankcase guard. On 1.6 MPI the number is usually available indiscriminately.
📄 The number is on the plate, not on the block: Check if the plate has been unscrewed by the previous owner. If it is not there, contact the service to check against the database Škoda.

⚠️ Attention: If the engine number is completely missing or clearly altered, this may be a sign of theft or an illegal replacement of the engine. In this case, we recommend checking the car through the traffic police database using the VIN code before purchasing.
