Localization and cleaning of the MAF sensor of the Opel Astra J 1.7

Model: Vauxhall Astra Astra J - Years 2009-2016
Part: Checks and maintenance

In this video, we see where the MAF sensor is located (which is used to measure the amount of air entering the engine): it is located right behind the intake manifold and can be easily removed. It is important that it is always clean, for optimal measurement, and to clean it effectively and safely, it is necessary to use a specific product designed to remove oily residues without damaging the delicate sensor filaments. For example, the code 146384678023 on eBay at a price of 16.89 euros, with free delivery. Alternatively, you can use an electrical contact cleaner, making sure it does not leave residues. Never use gasoline, solvents, or other aggressive detergents, as they could irreparably damage the sensor. Also avoid using compressed air, which could damage the sensor filaments.
