Really poor quality cap
Really poor part, did not fit a 2011 Ford Fiesta despite the part umbers being the same. The thread on the cap does not go all the way around and instead in in four ‘sections’ with gaps in between. Terrible! Ordered the same part number from another seller, looked the same cap but their threads went all the way around and it fitted perfectly.

Fits a fiesta 2013
Perfect fit for my fiesta. The old cap broke off leaving the inside stuck. The garage wanted to charge me £100 for a whole new compartment. Got to old cap out and replaced with this one at a fraction of the price.

En adaptable pour poser sur un Ford Smax (moteur Peugeot), convient parfaitement, pour bine moins cher que la pièce d'origine.

Nicht funktionstüchtig, da die Abdeckung eine Überhitzung des Motors verursacht
