While (still) boot leak chasing - what is this ? How to remove it ?

MK3 2007 plate

Just on the underside of the boot, black “grommet” looking thing

Sort of below the badge

I’ve tried (gently) prying with a flat blade, but it has not moved. I don’t like applying too much force when I don;t know how it is meant to come off (if at all).

I am presuming it is to see behind the badge, which is loose.

Any ideas ?

 

I have a theory water sprays up, gets behind at either the badge or the “grommet” and then flows into the boot as the panel is hollow here.

Either that or the rear light cluster needs a new seal, but that is not 100% conclusive yet.

Defo also got seepage around the high brake light, but that is for another day.

From your description, it’s the rectangular black plastic blanking plug between the two number plate lights. Lift boot lid and you need a small flat pry tool or screwdriver, looking at it with boot open, from left hand short edge push the plastic tang which you can’t see behind the blanking plate, horizontally from the left and prise out. Insertion is the reverse, engage on right side and just push it back in place. It’s outside the boot seal so water won’t get in via that, but just runs down the outside, behind the bumper panel. Is the boot seal itself OK, they can wear and split. Failing that, the rear light cluster seal possibly?

EDIT; just looked at your ppicture which doesn’t actually show anything? Are your roof drains clear? Is the carpet floor wet behind the seats? 

EDIT; just re read the last sentence, high level brake light seal  more than likely the culprit IMO.

 

Boot seal has a few nicks, but lower down. I’ve been hosing it to try and find the ingress :slight_smile:

I don’t think it is the light cluster, due to the water appearing 1/2 way down the boot. I used newspaper and there was no trail to it, it just dripped from above (left hand side, above “well”).

 

I’ve edited the post  again!

Behind seat is dry, high level light seal is on the culprit list (defo drops below that as well as over on the left).

 

Did the picture links not work ?

Hiya, yes but just shows a half open boot lid  no sign of your blanking plate image. If you use something like postimage to host your forum pics, you can insert the picture directly, so they show up on your posts, makes it easier for folk reading it rather than copy and paste into the search bar on theor browser, There’s a guide on here to help?

I read a thread where someone sprinkled talcum powder in his boot, this helped identify the source of the leak by leaving a trail where it had washed out.

Check your deck plate bolts are tightened down, i had one loose and had a slight drip there. Deck plates are the chrome strips each side on the rear panel behind the boot lid, they exist for the attachment of an hard top.

 

The black plastic blank can be prised out, here’s a picture of my boot lid after I removed it, gives you an idea how it fits, the hole on the left.

 

I’ve done the deck plates already, thanks. I had to use sealant on one :slight_smile:

Your boot lid looks different from mine  -->> Boot Lid

 

 

^^^ Yes it does, mine doesn’t have the usual paint blisters.

Sorry, it should be the same under there blank plate two plate lights either side of it.

It looks like yours needs treatment, paint lifting around the plate

 

Ah, yes, closer look yours has not got the bulb holder attached.

My plate looks to be a full rectangle and yours has a tab/lip to one side ?

I have a few places I need to treat the body work, this is what I get for going for a cheap one :frowning:

Don’t beat yourself up about it, the thing is, a lot of these cars suffer from these niggles, mine included it’s part of the joys of owning one I guess? If you like tinkering, these cars are great fun (until something goes wrong!) you’ll get to the bottom of it I’m sure, in the meantime, enjoy using it, better weather hopefully coming

Tinkering, oh yes Barrie!

Mines been up on ramps for the last two days, currently got a part off it (one of the engine/gearbox cover plates) looks worse for wear. Also doing some under body treatment, my missus told me I look like I’ve been down a coal mine too old for this now

 

I removed mine and drilled a 10mm hole through it and fitted a blue LED then fitted white LED’s to the number plate lights.
At night it throws a gentle purple and white hue across my number plate, looks rather interesting…and no you can’t see the blue LED unless you get your head below the boot lid.

hi , did anyone finally solve the water in boot problem?

 

In this case I have found it, just not solved it yet.

Resorted to the talc test. Very surprised to find it was coming from the cable clip, just below the tail light unit.

So, water is running behind the plastic cover, and down around the tail light then in the hole.

Not 100% sure if I should just pull the clip out, and block the hole then tape the cable to the body ?

Put some silicone sealant under theclip for now to see if that holds it back.
