l had my front windscreen taken out and re sealed, 18 months ago, but the leak is back again in same place. lt is running along the small seam,adjacent to the windscreen, on the left of the parcel shelf, on the passenger side and splashing down onto the side window switch. Has anyone had this problem?, be grateful for any advice.

Has a similar leak on Mrs_G's Doblo. If left facing down hill in the rain there would be water trickling down the inside of the windscreen.

This started about a year after the windscreen was replaced - I guess the fitter did a poor job and over time the sealant failed.

After a new screen was fitted the leak was cured.

I guess you could try using some "Captain Tolley’s Creeping Crack Cure" although this may make eventual replacement of the screen harder.
