Diagram ref no 5A

Fitted along the rear section of the sunroof panel, this seal helps maintain a weather-resistant fit between the sunroof and surrounding roof opening.

Over time, original rubber seals can harden, shrink or crack, potentially allowing increased wind noise and moisture ingress.

What Does It Do?

The rear sunroof seal helps reduce water and air entering around the sunroof panel while providing a protective seal between adjoining surfaces.

It also contributes to reducing wind noise and maintaining the original sunroof fit.

Why Does It Fail?

Common causes of deterioration include:

Age-related rubber hardening Cracking from sunlight exposure Shrinkage and loss of flexibility Repeated sunroof operation Damage during removal or repairs

When Should It Be Replaced?

Replace the seal if you notice:

Cracked, brittle or distorted rubber Visible gaps around the sunroof Increased wind noise Water entering around the roof opening Deterioration during sunroof refurbishment

Checks & Diagnosis

Inspect the seal for damage and check the sunroof panel alignment. Ensure the sunroof drainage channels are clear, as blocked drains can also cause water ingress.
