• Worth knowing A cap that vents and a cap that does not are visually similar, and swapping them gives a fault code or a pressure leak rather than a fit problem.

The photographs on a listing show the actual stock item, so compare the mounting points and the connector or fitting rather than the overall shape.

Check the number on the part you are removing before ordering. If it is worn off, send the VIN and a photo and we will match it.
