I have a leak in the boot area of my XF, is this a common fault with this model, looking like a minimum repair of £2500, very disappointed in what I thought was a class car

 

Welcome to the forum Mcarey61,

I've moved your post from XK8/XKR to X250 forum and deleted the other identical one from Jaguar Forums Feedback & Suggestion Centre forum. This is the place for posts about your model.

Please follow this link New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum to the New Member Area - Intro a MUST forum and post some information about yourself and your vehicle for all members to see. In return you'll get a proper welcome and some useful advice about posting to the forum.

My guess is its the rubber seal around the edges of the trunk. Take a hose, wet the back of the car, open the trunk and check the rubber gasket sealing the trunk aperture - you will be able to see the line where water is stopped by the seal when the trunk is closed - as well as where water is getting by.
I replaced the seal on my older Audi A4's trunk two years ago when it developed a trunk leak and it's working great ever since. Usually these seals are not very expensive and you can fit it yourself. Jaguar will sell them in meter lengths so you just buy enough to go around your trunk and pull the old one off, and clip the new one into place - they usually have a bit of silicone sealer holding it on and you can also put some on if you want it to really stay in place and protect the body from rust.
If your car has a sunroof, then it could be the water channel from the sunroof that has become disconnected in the trunk area.
The sunroof has channels that channel water from the roof and down little pipes that come out in the C-Pillar of the car behind the carpeting - there is one on each side of the C-pillar - each plastic pipe (usually white) has a rubber connecting hose which channels water down and out the car at the rear and these rubber hoses can become disconnected which means, water will now just channel into the trunk instead and well up on the spare wheel well.
To check that these hoses are connected properly, you gotta pull the carpeting away from the sides of the trunk and you should see them (IF you have an XF with a sunroof).
My 2010 Cadillac CTS had this issue and it turned out to be the rubber hose pulling away from the plastic drain channel hose half way down the C-pillar. Reconnected it, pulled all the carpeting out the car and let it dry in the sun. Had to suck all the water out the spare wheel well with a water vacuum. It never leaked again!
Hope this helps.

 

What MY is your car? Older models had a factory issue where the panels aren't properly glued together on the back at one point and the seal leaks. The water seeps in from beneath/near the right hand rear tail light. Had that on mine, cost ab. 150€ to fix at a specialist shop. Take the boot trim out, it's easy enough to do, and look for any signs of a leak/run. They look "dirty".


Also it could be the rear window. Mine had a spot with sealant missing on it. Again, an issue with the older cars. Took Jag a bit to dial in the robots, I guess..
