How to Clean the Throttle Body on the Lancia Ypsilon

Model: Lancia Ypsilon 843, MK 2, Ypsilon 2, Y2 - Years 2003-2011
Part: Throttle body

To clean the throttle body, first remove the air box using a 10 mm hex key; it is best to perform this operation with the engine cold. If the air box does not come off, there may be a third pressure screw. At this point, you will have access to the throttle body. For cleaning, use a mechanical parts cleaner; if the throttle body is not particularly dirty, you can clean it without removing it. After the initial cleaning, perform another cleaning with the engine running and revving the accelerator; you can also clean the pressure sensor located on the intake manifold (use an electrical contact cleaner), spraying from a distance without using cloth. Afterwards, reassemble the part.

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.
