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.

How to Open the Bonnet of the Ford Transit Custom

On many Ford vehicles, opening the bonnet is not done using the traditional lever located in the cabin, at the bottom left on the driver's side. Instead, you must use the ignition key to unlock a lock positioned at the front of the vehicle, usually beneath the manufacturer's badge. The reason for this choice is unclear, but it can pose a difficulty if the lock becomes jammed, risking damage to the key. You can try to disengage the lock by inserting a long screwdriver through the grille of the front panel. Once the first opening is achieved, spray some unlocking fluid on the lock to allow subsequent activation with the key.
