Hi there, thanks for adding me! We've had our 2016 X-Trail for just under 2 years and I noticed water coming in under the dash on the drivers side. Nissan looked at it and said it's the sunroof drain leaking, but want nearly £700 to diagnose and fix it. Has anyone else had this problem? Is there anything we can do ourselves to try and clear it? It may be that the drains are perished but I would like to try before spending that much money! Appreciate any advice, thanks.
