How to clean the throttle body without removing it

Model: Vauxhall Astra Astra J - Years 2009-2016
Part: Throttle body

Let's see how to clean the throttle body of an Opel Astra (specifically with LPG system) using a specific cleaning spray, such as Ambro-sol A469, which can be found on Amazon with the code B078Y2JXD1 for £11.49, without removing the component. First, warm up the engine for a few minutes, disconnect the air hose connecting to the throttle body, start the engine, and hold the accelerator pedal at about 1,500/2,000 RPM. Spray the product directly onto the throttle body for about 5 minutes, in intervals, ensuring the engine does not stall. Then turn off the engine and let it rest; repeat the operation. Reattach the hose and take a test drive for 20/30 minutes, revving the engine to expel dirt and residues through the exhaust. This cleaning should be done every 30,000 miles (or even 20,000 for those with LPG).

How to Reset the Central Locking of the Volkswagen Golf 4?

If the central locking system of the Volkswagen Golf 4 is not working, it is likely necessary to reset the system: to do this, open the driver's door and detach the side panel of the dashboard next to the steering wheel. Under this panel, you will find the fuses, including the one for the central locking, which is indicated in the manual as number 14. To reset the system, remove this fuse from its housing, then reinsert it or replace it with a new one of the same amperage: this will reset the central locking system.
