Here's a funny one - I thought I had somehow lost a bottle of water in the back of the car - searches never found it and it was only in the recent cold weather that I realised the water is inside the rear tailgate! Removed the two bungs from the underside and litres of water came out! Spoke to the main dealer and they booked it in for water ingress without even a murmer. Seems like this is something they already know about as they said it would need to be booked in for a week! This is a 2023 SQ7! Anyone else had this on a Q7?
