Roof opening panel - sliding central glass panel

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

In the case of the sliding central glass panel, the rubber seals and the lock actuator or latch mechanism must be checked first of all.
Make sure to follow the diagnostic steps outlined below to rectify any issues with water ingress around the roof opening panel first, BEFORE resorting to any alternative action (for example, replacement of the roof opening panel frame assembly).

Check the seals on the sliding central glass panel, rectify as necessary (for diagnostics for roof opening panel seals, refer to appropriate service information.)
Check the correct adjustment of the sliding central glass panel, adjust as necessary, replace any worn or damaged components as necessary.
Check the internal seal of the roof opening panel frame, realign or install as necessary.
Check the water drain channels and holes for blockages, clear blockages as necessary.
The roof opening panel frame incorporates drain holes in each front corner allowing water to drain through the A-pillars and each rear corner allowing water to drain through the roof panel channels. Check the drainage system for unhindered flow and rectify as required.
