Fitting an Additional Chip Tuning Module

Model: Fiat Doblo 223, MK 1, Doblo 1 - Years 2000-2009
Part: Control unit

Open the bonnet and locate the pressure sensor on the rail: it is on the left side (when facing the engine) near the oil level dipstick. At this point, using a small screwdriver, unclip the connector's safety catch and then the connector itself: install the additional module by creating a bypass, connecting the original connector to the module's wiring and the outgoing connector from the module to the pressure sensor; then find a location to mount the module without interfering with moving parts and excessive heat.

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.
