Under the front hood, there is a sound-absorbing insulation made of sponge-like material that deteriorates over time until it crumbles completely; however, replacement insulation is readily available and should be secured with adhesive: it is recommended to use spray adhesive.

Start by removing any remnants of the old insulation from under the hood, thoroughly cleaning the surface with solvent; then spray the adhesive both under the hood and on the insulation evenly, allow it to dry, and apply the insulation by pressing it down uniformly to ensure a perfect bond.

Once the tyres are inflated, turn on the instrument cluster to check that the warning light has completely disappeared from the display. If it is still present, you may need to drive for a few miles to ensure it disappears completely from the screen.
