We bought "Becky" (2010 Panda Dynamic Eco 1.2) shortly after the turn of the year and almost right away realised that water was leaking into the boot. I was fortunate enough to get her for a very good price so was not particularly surprised that the dealer (quite a small concern) whilst not being unpleasant about it, was not interested in doing anything about it. I browsed our forum and found quite a few entries on the subject, mostly from people who were not succeeding in curing the problem! As there were other, more urgent things to do (timing belt etc) I decided to just mop up as needed and come back to it later. Then the good weather came and it wasn't raining and we were going on holiday so it got put back again!? Last few days though the rain is back and the boot floor is swimming! So better try to track it down before winter sets in!

First I emptied out everything in the boot and found that the boot liner which sits on top of the spare wheel was soaking wet around the pull strap and foam pad which rests against the rear panel (just below the lock)

The boot floor had a good couple of sponge fulls of water in the wheel well

Which I cleared out. This was just after one night of moderate rainfall

P1070659.JPG

I had a really good look and feel round the boot and under the rear seat. Below the rear window seals etc, etc. All dry but as I was doing this I quickly noticed that there was water around the lock fitting and a small drop further down the panel inside the boot. There were also "witness" marks on the inside of the panel around the exit "flapy thing" which lets air out through the rear panel which indicated that water had been running down from the area of the lock

P1070647.JPG

P1070648.JPG

At first I though water was getting into the rear hatch somehow and running out through the lock to dribble down the inside. Strangely though, although the parts you can see in the pictures above were very wet there was no sign of water on the lock in the hatch or any sign of water leaking from inside the hatch. OK. Maybe it's something to do with the seal? So I carefully pulled the seal off all along the bottom of the aperture. Starting just to the right (Off Side) of the lock I was immediately greeted with wetness.

P1070658.JPG

If you look carefully you can see that there is dampness to the left of my thumb but not to the right of it. This picture was of the seal where it fits in the bottom right corner Continuing to pull the seal off until I had almost half of it off, up to about a foot vertically on the left (Near Side) and almost to the top on the right (Off Side) - because that was the side where the water seemed to be - it was obvious that water was lying inside the section to the right of the lock but not to the left or any higher up the sides. The inside of the "U" section of the seal was very wet as was the flange on the body, but only that bottom part, from the lock to the corner where the seal starts to go vertical. Oh, hello, do I see sealant in the bottom of the "U" section of the rubber seal?

P1070651.JPG

Looks like glazier's putty? And not very much of it either. As I look round more of the seal I've already pulled off I can see further evidence of it. Looks like someone else has been in here before me chasing this leak.

Water leaks can be very difficult to sort. I remember, when new to this game and being the "Laddy" who was often shut in the boot to look for leaks whilst one of the "men" played a hose on the outside, being amazed to learn that water can happily travel "uphill", by capillary action between seals and panel joints, to reappear quite some distance and "uphill" from it's entry point. So I don't like to rush too hurriedly, into action before considering all the clues. Went and made a cup of tea and stood looking at it for a wee while. Oh, wait a minute, just look at that panel joint.

P1070655.JPG

P1070656.JPG

If you look just to the right of the flange you can see an overlapping panel joint which runs downwards towards the left and is not completely flush so forming a very small "groove" through which water can run from the outside to the inside of the "U" of the seal. Interestingly this is where the wetness starts which you can see in the picture featuring my thumb! I'm about 90% sure I've found it now!

But why doesn't the other side (Near Side) have the same problem? It's completely dry and there is the same panel joint? Look carefully.

P1070660.JPG

The joint runs downwards towards the right so it's encouraging water to run towards the seal isn't it? well yes, but look at the witness marks (black) where the seal has been gripping. Continuous right through the area of the joint isn't it? Which seems to indicate that the seal deformed enough to effect a seal but also, just to the left hand end of the joint is a depression (it's clearer with the naked eye) which is not there on the right hand side joint, which I think will be encouraging water to flow down and away from the "groove" of the joint?

So what to do now. Well I think it's highly likely the water is getting behind the rubber in that right hand corner and then running along the "U" section to reappear at the lock where it's then running down the inside of the rear panel to collect in the wheel well. The person who tried to cure it before me had the right idea but maybe didn't actually isolate where the leak was as he/she applied sealant all round - or maybe just decided to cover all the bases? Also nothing like enough sealant was applied and the sealant itself was not the best choice and unlikely to be effective. I intend to use Geocel "The Works" which can be applied to dry and/or wet surfaces. Not the cheapest but wicked stuff! Just hope I don't have to remove it later!

Hope that others experiencing this problem find this useful. I'm needing to buy service items for my youngest boy's wife's Jazz so I'll stop by Screwfix on the way to buy the sealant. I'll give it a few weeks and report back on whether it's cured or not - "Cured", get it? Oh dear, I've been sat at this computer for too long! Keep your fingers crossed for me!
Regards to all

Could it be the sela was not properly fitted at some time and the gunk used to seal the original problem is what's now causing the leak?


It might be worth trying a used seal from a scrapyard / breakers and doing your bloke inside with a torch trick. Used door seals can't be expensive? Can they?


Also check the car VERY carefully for crash damage. It might well have been repaired solidly but that seal "upstand" might not be sitting totally correct. Or it might have had a minor bump that affected the seal upstand more than anyone realised.
 
Thanks Dave. In fact the seal looks to be in very good condition. It's nice and soft and grips the flange quite tightly. I'm guessing it's been replaced recently, still leaked so someone then tried the sealant?

The dealer from whom I bought the car was very obliging and let me use his ramp to fully inspect the underside. I did 5 years on car sales at one time before going back to life in the workshops (just love to be mucky!) I examined the car very carefully indeed before parting with my cash and couldn't find any body problems at all. It did need brake work and a cam belt and some other minor stuff which helped me negotiate. However I will carefully check the alignment of the flange (didn't think of that one).

Might just put one of my boys in the boot though and "play" with the hose myself!
 
Just felt a wee update on Becky's incontinence problem (wet boot floor) might be of interest?

Sanity has returned to our house with the departure of my daughter, her husband and children after their long weekend with us so they could take in Edinburgh festival events before it all finished. Our other grandchildren and their mums and dads were in and out like yo-yos too. All this activity has required transport and Becky is absolutely ideal for nipping in and out of the insanity that is Edinburgh traffic at festival time consequently she has racked up a few miles. There was just time last night, after returning our youngest grandchild home, for a quick check over before dinner.

It's not been long since I did a major service and renewed the timing belt (Inc water pump) so it was pleasing to find that everything, coolant level, oil level, tyre pressures, etc, etc were all absolutely spot on. Less pleasing to find a wee puddle in the boot though.

Got up this morning to a beautiful sunny day. Mrs Jock decided to do a big wash (yes I did help strip the beds!) So decided to do a bit of detective work on Becky's leak. Started off having a look round the joint between the hatch and rubber seal. It's definitely touching all the way round but compressing it more at the top than the bottom. Next I removed the rear door (hatch) seal and blew all round the sealing "slot" with my air hose. My compressor runs 130psi so this cleared out all the moisture and most of the fragments of putty - yes it was glazier's putty - from "whoever's" previous effort. I then played the old hair dryer I have along it to be sure and dried the flange edge on the car. Reinstalled the seal. Rigged up the garden hose by cable tying it to the aerial. Gently turned the hose on. Climbed into the back of the car with my led work light and nothing seemed to happen except that no leak appeared! However after about 5 minutes, just as I was about to call it a day, one wee drop of water appeared at the lock, ran down the inside of the panel and dripped on the boot floor. Considering there has never been more than about an eggcup full of water when I've previously checked, perhaps this is it! The long suffering Mrs Jock was having a quiet cuppa whilst she waited for the washing machine to finish so I got her to come out and play the water all over the back of the car whilst I kept watch inside. I paid particular attention to the rear light fittings (thanks Koalar) but all seemed dry. Oops! There's another drip at the lock! Looked very closely at this. The water is not appearing between the seal and hatch but is coming out between the seal and body.

So, pulled of the seal up to about the level of the back window, both sides, and again, as I originally reported in earlier post, there's wetness, inside the "U" section, from that seam joint on the OS down to the lock. Nothing on the NS or higher up. The water's got to be getting past the inside of the seal, at that seam and running along. The "U" of the seal is completely dry higher up so, with the bottom two thirds of the seal pulled off already, I repeated the cleaning and drying up to the level of the back window and injected bathroom silicon (left over from recent reseal on the bath) into the "U" section of the seal and pushed it very firmly back onto its flange. Surprisingly I seem to have used just the right amount of sealant as it "squished" out just a little but not too much and with Becky being white it blends beautifully!

As I was inspecting my handiwork I noticed the air flap valve which is on the rear panel of the boot, just above floor level. I ran my finger around it and it came away wet! I think this is almost certain to be water that has run down from the seal above it but, as this fitting proved easy to remove (four little plastic clips) I did so, cleaned it all up and sparingly applied a little of the sealant to the foam seal around it's perimeter before refitting it.

Finally, just as I was about to walk away, I remembered that I had noticed the seal was not being compressed quite so much at the bottom than at the roofline. Winkled out my trusty 10mm socket and "T" handle, slackened off the hatch striking plate and adjusted it inwards slightly until the hatch, when closed, is compressing the seal evenly all the way round. Gently fully tightened the two striking plate nuts. The immediate and unexpected result of this is that the hatch, which previously closed with a bit of a rattle, now closes with a quality whump and no rattle!

So now I suppose it's a case of standing by, with fingers crossed, and waiting for the next rain storm (sure I won't have to wait long). Feeling quite confident though that I've probably "got it". Oh please let it be! I really don't want to have to clear off a whole lot of solidified silicon sealant! Hopefully I'll be able to report a happy outcome, within the next week or so, to close this thread.
 
Well, it's been raining since the wee small hours and really quite heavy mid morning. More like a Scotch mist just now (the idea of a Scotch mist as against a Scots mist interests me. Would the Scotch mist be alcoholic?).

Anyway, it means Becky has got very very wet! Just went out and opened the rear hatch, with fingers crossed! WhooHoo! Not a trace of water anywhere. No puddle in the wheel well, No water on the rear panel or around the lock. No water under the wee bit of rubber seal which I carefully peeled back, maybe shouldn't have done that in case it's disturbed the silicon? Oh well, too late to regret!

Although maybe a bit early to be absolutely sure, I can say that previously there would definitely have been a puddle after this much rain! So, looking pretty hopeful I've got it!
If I don't post again you'll know she's behaving herself.
all the best.

So (forgive me), but was the eventual fix in getting the door lock alignment sorted out?
Nothing to forgive Dave, happy to clarify.

Adjusting the lock may have contributed, difficult to say as I did both the sealant and adjusting at the same time. My own feeling is though, that the water was traveling along that panel seam in the right (off side) bottom corner and getting inside the "U" section of the seal where it then travelled along to reappear at the lock. I think this because there was never any sign of water on the outside of the sealing face between the hatch and seal and there was always wetness inside the a"U" of the seal when you pulled it off the flange on the body. Also you could see the wee drips coming out from under the seal at the lock.

All the best

I've slightly lost track of time as there's been lots of "stuff" (kid's birthday party, autumn onslaught on my garden, lawnmower which wouldn't start - faulty spark plug, been a long time since I had one of those - and sourcing 4, yes 4! new tyres for daughter in law's Fabia Scout. I think it's been almost two weeks since I tackled Becky's leaky boot. As you can see from the above the outcome seems good so I thought that, if it was still dry (we've had some quite short but heavy showers recently) I'd put the spare wheel, floor mat and emergency spares box back in.

Very pleased, ecstatic actually, to be able to report she's still absolutely dry! And I've been thinking, after Dave (above) asked for clarification, about what was the most likely reason for the leak in the first place. The more I think about what I found and the fact that there was wetness right under the seal, I am convinced the problem was water getting past the seal at that panel joint on the OS and travelling along inside the "U" section to reappear at the lock. The adjustment to the tailgate lock was very small, in the order of 1 or 2 mm. But I wasn't able to see any evidence of a leak between the tailgate itself and the seal (the seal can be easily seen from the inside with the tailgate fully closed so you would see if it leaked).

And I suppose, now that I've put all the gubbins back in the boot, I'll find it all soaking wet tomorrow morning!
 
OK, this is my last post on this subject - probably?

We've been away for 10 days and Becky has been parked nose in to our house, so her back end has been fully exposed to all the weather. I believe there's been some quite wild weather whilst we've been away - part of my neighbour's fence is down! We have just been out to the local supermarket for milk bread and other essentials. Before we set off I removed the boot floor mat and spare wheel and I'm more than pleased to be able to report there's still no sign of water leaking into the boot!

So. I think it is reasonable to say that I've stopped the water leak! (for now anyway). Also, whilst sitting in the sun sipping at my lemon soda (can't take alcohol anymore after my tummy op - BooHoo!) I've convinced myself that all the evidence points to the water traveling along inside the U section of the seal as mentioned above.

Whilst it was easy to see that water was collecting in the spare wheel well, it was not at all obvious how it was gaining entry. I hope my exploration of this problem has been helpful and, due to the way that the offending body seam is joined, I would not be too surprised to hear that some of her brothers/sisters suffer from wet backsides attributable to the same problem.
 
I'm not sure if I should apologize for reawakening this old thread of mine? but bodywork water leaks are such a faff and often so difficult to find a cure for that I thought you might all be interested to know that Becky still has a wonderfully dry "backside" (boot).

The reason this came to mind was that yesterday it absolutely poured with rain for most of the afternoon - I mean windy and gutters like rivers. I hadn't had reason to lift the boot floor for nearly a year so I just thought I'd have a look. Delighted to see it all dry.
 
Good to hear it's (she's) still leak free. Its good to hear from you, your absence on the forum is noticable, well by me anyway ;)
Thanks Kronkron. In fact I have been around and have posted mostly in the Leisure Lounge and Tech Talk. Unfortunately we've had three family members suffer very serious health issues, one of which started before Christmas. Two could have gone catastrophically wrong and it's been very stressful but the wonderful people in our local hospitals have saved the day and only now are we on the up. Thankfully all are now recovering well although with one it's going to be a long haul.

We joke that we just cancelled Christmas/New Year (and New Year is a big family thing up here of course quite apart from all the stuff you see about the partying on TV) and postponed it 'till next year. I do a wee yearly info sheet (half an A3 usually) which I tuck into the Christmas cards to the older friends who, because they live down south, we don't see so much now. Mrs J is joking to friends that it'll have to be at least a whole sheet next year to get everything in.

Thanks for your kind words.
best regards
Jock
 
Its been similar in my end of the world, from illness through to the celebrations! There is a big Scottish (and irish) contingent where I live, in fact most of the other side of the family are from Greenock.

Fingers crossed that everyone makes a full and speedy recovery. I have genuinely missed your input and contributions.

All the best.

Happy new year Pal!
 
I saw the title and thought, "Hey Jock had hassle with that, lets find the link".

Here's hoping 2020 is a better year for your family. (y)

I probably need to apologize for resurrecting this thread but I just mentioned it in a post in the "grumpy" thread with Max about water leaks and got distracted into rereading it.

First off, I'm very glad to be able to say that the absolutely hellish time we had at the beginning of the year with illness in the family is greatly improved. We've had a lot of contact with services provided by the NHS during this time and my respect, admiration and deepest gratitude to these over worked and dedicated people is bottomless. Saying thank you seems so totally inadequate.

I say in the above post that we "just cancelled Christmas and New Year and will postpone it 'till next year" Well, that's really not looking like a "goer" at this time is it? Also that next years Christmas letter to our friends might have to be expanded to a whole page to catch up - I'm going to be scratching to think of things to say. Maybe I could describe the difficulty I had painting round the radiator in the wee toilet? Or enthuse about the new Henry Hoover I've just bought (we've named him Norman, but I won't go into that unless someone asks). Of course there's the table lamp I rewired too! Strewth, I really am loosing it aren't I
