Clean the Throttle Body Without Removing It

Model: Fiat Punto MK 2, 188 - Years 1999-2011
Part: Throttle body

If there are fuel delivery issues with fluctuations in engine RPM, it is necessary to clean the throttle body adjustment system. The first step is to loosen the air hose clamp. Once the hose is removed, you can observe the dirtiness of the regulator. It is possible to clean the regulator without needing to disassemble the entire unit, simply by using a special spray. Initially, clean the inlet of the regulator using a cloth soaked in the spray, avoiding contact with the throttle plate. Start the vehicle and, while the engine is running, spray the cleaner into the inlet with small bursts, ensuring not to draw in any foreign objects during this process. If the throttle plate is not touched, calibration is not necessary. Refit the hose.

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.
