Windshield Water Ingress: General
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:
- If water leaks are noted at the front end of the headliner, this may be as a result of windshield water ingress OR water ingress from the pano roof glass (if installed). To correctly identify the point of water ingress, lower the headliner and look for evidence of water ingress both from the windshield and the pano roof glass BEFORE continuing with the diagnostics described below. For guidance on diagnosis of pano roof glass (if installed) water ingress, see separate article in this information (REFER to: WATER INGRESS DIAGNOSTICS ).
- If water ingress is evident, perform the following procedures below.
If water leaks occur, the cause can be established using the checks described below. A systematic and logical procedure is required to locate water leaks. Before beginning extensive checks, a thorough visual inspection must be completed.
- Visual Inspection
- The following characteristics may indicate existing water leaks:
- Check the clearance and accurate fit of ancillary components such as the hood, tailgate, doors, and so on.
- Check for correct fit and possible damage to sealing elements such as blanking plugs, rubber door weather strips, and so on.
- Check water drain holes for unhindered flow.
- Various tests can be used to provide further information on possible leaks:
- The breaks in adhesive beads can be located by using compressed air from inside the vehicle. The leak location can be identified from outside by the escaping air.
- Water test
- Washer test
- Road test
