How long

[t90ark]

Hi All

Just a general enquiry, if I may.
I am resolving the good old leaking boot problem. I think I've won - top boot seal seemed to be the culprit. We're due the first heavy rain since I did it later, so that'll be the acid test.

My question, for those that have suffered the same leaky boot scenario, how long can I expect water to keep coming up from the chassis rails? Obviously it'll depend how much water is in there, roughly, though.

There are 3 main areas of concern. The boot vents, light seals and top seal. The vents seals can go brittle and leak. Older light seals can leak; you should check they are seated correctly inside the boot, too. The top seal leaks due to degradation of the original sealant - particularly in the area of the 2 screws shown; you basically remove the seal and apply gutter sealant or similar. My leaking boot has cost a roof motor, aerial amplifier and failed ebrake.

Something never pointed out with water in boot are the rubber bungs in the back of the car.

When you pulled the bumper is there a technique for removal of the top part near lights rear wing etc taking mine off to fit reverse sensors and worried about breaking the top tabs on the bumper top edge

I think i just pulled.........and broke some tabs

Best do it on a warm day when everything is more flexible.
The bumper side has quite weak slots and they rip out.

Found a pic i took.

Try pushing bumper up before pulling out.
Perhaps try to remove near the wheel arch first, looks the weakest.

See round hole i seem to remember that was a screw you remove from below.

Cheers for that very helpful

Couple more views with grommets potential leak areas.

 

[peter2704]

Was this Nader the impression you could remove bumper and leave lights in place

 

[flybobbie]

Easier to remove lights so you have the edge of the bumper to grip in the light area.
Also save damaging the lights.
