Replace Remote Key Battery

Model: Fiat 500 312 - Years 2007-2024
Part: Key

The battery for the remote key of the car model in question is located on the side of the remote itself, in a compartment that remains concealed when the key is closed; therefore, detach the mechanical key and open the covering shells of the remote. At this point, unlock the battery compartment, remove the battery holder, and insert the new battery, ensuring the polarity is correct; then re-secure the battery compartment and snap the remote shells back together.

How to Change the Diesel Filter on a Renault Captur 1.5 dCi

The diesel filter on the Renault Captur is always of the immersion type, but instead of being located at the top of the engine bay, it is positioned lower, inside the front right wheel arch (passenger side), practically under the headlamp. To replace it, it is advisable to lift the vehicle, remove the front right wheel and the corresponding inner lining to access the filter location. Unscrew the fastening nuts of the support clamp to extract it from its housing and disconnect the connector and pipes. At this point, unscrew the fixing screws of the cap, remove the old filter and insert the new one, also replacing the O-ring seals, and then reverse the steps for installation. Before starting the engine, turn the ignition on and off several times to allow the filter to fill.
