Water in boot lid

[Rolfe]

I just merged this thread in with that one to keep it all together, as it's a recurrent issue.

This might be a public service announcement as I'd no idea my car had a leak. Maybe next time you open your tailgate you should check yours.

Yesterday I needed to lift the boot floor on car. I was very surprised to see a puddle, loch, lake of water lying in lowest part of the boot. The attached photo shows what I'm talking about. The shiny bit is the puddle of water which was left after I'd taken the tray with the finilec, compressor, tools etc out. The boot floor carpet was obviously soaked where the water had collected but there wasn't any other wetness I could find. View attachment 38304

Anyone else had this problem? If yes, did you find where the water was leaking in from?

4 attempts at 2 different dealers with the final visit being a week. Exactly the same situation. There is a service bulletin to apply sealant to a panel (didn’t fix it). There were many many clips replaced getting to things but the leak was fixed.

Thanks. Was it replaced under warranty?

No. I pulled the seal out a bit and it's been fine since. Couldn't be bothered with the dealer and the potential crap.

I noticed today that there’s water collecting in my boot floor — probably a couple of pints or more. The entry point seems to be around the driver’s side storage pocket, as that area is soaked while nowhere else is affected.

Has anyone else experienced this issue?

Another merge, to keep it all together.

oh, never noticed any dampness before (over 3 years) but just joined the party.

I suppose I should really take out that padding stuff and look at mine, some day.

But ignorance is bliss.

dealer couldn't look at my water issue while it was in today (not unexpected), they will need it for 2 days to investigate and they have no courtesy cars for 3 months Oh, and rubber seals are out of warranty after 3 years so if it turns out to be the boot seal it won't be covered and the £160+ investigation fee will be payable - what a joy MG are. Best get my dehumidifier out and see if I can rule out the boot seal.

Dry the boot out, then use a hose pipe and starting from the lowest point of the car !.
Use the hose and slowly working from one side, progress to the the other side of the car.
Make at least two passes across the car at the same level and stop.
Have somebody checking for any water ingress.
When you are happy you have no leak, then repeat the process one one time, then raise the level of the hose pipe and make two more passes.
Now pause and check again.
Repeat the process systematically until you have reached the roof level.
Remember to bring the hose around each side, onto the rear wings.
Why included the rear wings ?.
Because behind the the rear bumper cover ( on both sides ) there are vents flaps, that allow air to escape when the doors are closed etc.
These one way vents / flaps have a habit of not closing properly when they age.
Therefore water ingress is allowed into the boot.
This is a common problem on many cars.
A relative of ours complained that he could hear, what sounded like water swishing inside the car in his 5 year old Ford Focus.
When it went into the garage, the boot had over an inch of water !.
The vent flaps had deteriorated and was allowing water into the boot, the frame distorts and allows water to pass behind the plastic frames.
Here is a photo of the vents / flaps on the Focus.
If you do a quick google search, you will see plenty of owners with this problem.

I had the same problem with my focus. The water used to run down the gutter surrounding the tailgate, get deflected by the light housing, down the side and onto the top of the vent where it made its way through the top of the now defective seal around the vent.
The cure was to remove the rear bumper and the vents, remove the now sodden sound deadening and then use a good quality adhesive sealant (I used Sikaflex 221) to stick the vents back in place.

Looks like purposeful design to me, keeps your spare tyre nice and clean for when you need it
