This seal helps maintain a weather-resistant fit between the sunroof panel and surrounding roof opening, reducing wind noise and limiting moisture ingress.

Over time, original sunroof seals can become brittle, cracked or compressed due to sunlight, temperature changes and general ageing.

What Does It Do?

The sunroof seal provides a protective barrier around the corresponding section of the sunroof assembly, helping reduce wind noise, water penetration and unwanted vibration.

Why Does It Fail?

Common causes of deterioration include:

• Age-related rubber hardening
• Cracking from sunlight exposure
• Shrinkage and loss of flexibility
• Compression from repeated sunroof operation
• Damage during maintenance or repairs

When Should It Be Replaced?

Replace the seal if you notice:

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

Checks & Diagnosis

Inspect the existing seal for damage, compression or incorrect positioning.

Check sunroof alignment and ensure the drainage channels are clear, as blocked drains can also cause water ingress.

Installation Notes

Remove the original seal carefully and clean the mounting area before fitting. Ensure the replacement is correctly positioned without stretching or twisting.

Check sunroof operation, panel alignment and drainage following installation.
