Need some help & advice. The sunroof on my P38A (2.5 DSE) is leaking on one corner, also sometimes the central light fitting by the windscreen occasionally fills with water????However these leaks don't seem to happen if the car is parked facing down even a slight slope??? Had replacement sunroof fitted, Same Problem!!!!!! Any help / advice would be welcome at this point.

Hi,

Check the drain tubes are not blocked. Pour a little water in to each front corner of the
the sunroof frame and make sure it runs out of the drain tubes under the front wings.

Every sunroof will leak water to some extent, that is the reason for the drain tubes. Yours are certainly blocked, try to clean them with an air compressor or even better, with a length of wire.
