Hello Board
While replacing my battery I noticed a minimum of 2" of standing water in the bottom of my trunk.
Does anyone know the source of this issue of:
1) how is the water getting in there?
2) why isn't it draining out?
3) Can anyone please explain where do I plug in the connector that is circled? While vacuuming out water I noticed it was disconnected.

 

That connector is supposed to be unplugged, it’s only used during shipping.

Yikes. There are a number of threads here about checking for plugged drainage holes, I’m not sure where they are.

 

Yes, that is entirely superfluous once the car is delivered…much more importantly, how did that much water get in, and why/how are the drains plugged?

 

I had water there too. It turned out to be a special sealing clip that wasn't sealing. I'd only get water intrusion during heavy rain, so it was difficult to track down.

First, you need to get that dried out thoroughly. Once that's done you'll need to put the car in a position to let water in again and find where water is coming in. For mine, I could feel the carpet was wet on the passenger side.

The liftgate has a seal that goes down both sides. It is held in place by pretty standard looking clips, like you'd find holding door cards in place. They do have a difference though. There is a rubber part that seals the hold the clip snaps into, and it wasn't sealing for me. I lifted the seal and put some 3-M strip caulk (often called dum-dum) around the clip and that solved the problem. I ran a piece of black vinyl tape the length of the seal at the outer edge to hold it back in place. If this is the problem for you, be advised that the weatherstrip tears very easily once it's a few years old. You might be able to push down on the place where the clip is to seat it better. I'd already torn things apart by that point, so used the strip caulk to be sure of a seal.

I hope this is helpful.

 

I don't think there are drains there, at least none like I expected (water can drip out through a slit in the rubber piece but it prevents water spray from entering. I vacuumed out the water and then used a "Metro Blaster" blower to get the water from under the battery tray. I propped it there for a while until no more droplets came out.

Seems like a similar situation.

 

Helpful thread on the UK forum covering potential points of water ingress

I had a similar problem, so it's something that Jaguar didn't address up to early 2020 cars at least. I followed some of those steps for sealing around the clips shown and, so far, it has survived all the car washings and severe rainstorms we've had since.

 

Hello, I read that you had a problem with water in the trunk of the F-type. Unfortunately I have the same thing. Can you help and tell me what needs to be done to seal the trunk? Which clips need to be sealed? Regards, Darek

 

See post #4 above for my remedy. Is that what's causing your trouble? You'll need to figure that out. Others have reported different points of water ingress. I took everything out of the trunk area and lined it with newspaper. That gives a pretty clear indication when wet and is much easier to spot than on the black carpet lining. You may even need to remove the side linings to isolate the cause.
