I’m going to reseal my C1 by your method tomorrow. Also the vents behind the rear bumper, poor seals there as well. Thank you for very informative films about the city bugs. Really helpful an easy to understand. Great!!!

My stepdaughters C1 had a boot full of water...I did not have a clue where it was coming from but found your KZfaq channel and took the advice as to deal; with this issue, so after a visit to the local hardware store and some silicone purchased I followed your instructions to the letter...and...EUREKA!" Problem solved! thanks a million for imparting your knowledge in an easy to understand manner, Easy to follow for us 'Lay people' Once again thanks aaanton11!

Thank you so much, my local peugeot dealer was going to charge me £300 just for a water check and no repairs. this has saved me ALOT of money! Thanks again! :D

I have just bought a 107 (06 plate) for my son and noticed this issue- so glad its such a simple fix. Thank you very much for your clear and useful instructions.

Discovered a boot full of water on the wife's car , it doesn't get alot of use but this video has helped a massive amount, job for the weekend, thank you

I did it two days ago after watching your video. And I applied a sealant not on the seal on the lamp itself, but on the body car. Adhesion to the metal of the body, I think, will be much better than to the dirty seal of foam rubber. It does not degrease does not work, and rubbed the metal with a degreaser. It turned out well. To speed up the drying warmed with a hair dryer. Now you can remove the lamp and quickly put it back when you need it. I wish you success! Я сделал это два дня назад после просмотра вашего видео. Причем я наносил герметик не на уплотнитель на самой фаре, а на кузов. Адгезия к металлу кузова я думаю, будет гораздо лучше, чем к грязному уплотнителю из поролона. Ее не обезжирить никак не получится, а металл протер обезжиривателем. Получилось хорошо. Для ускорения высыхания грел феном. Теперь в любой момент можно будет снять фару и быстро поставить обратно. Желаю успехов!

This was incredibly helpful, I'm about to about to sell one of these C1s to my mother in law, and thanks to a bit of rain the past couple of days, I realised that re-fitting the top half of the boot seal wasn't enough to solve my leak as the headliner was soaking wet and a puddles had formed in the boot and wheel well (AGAIN)... Thankfully I came across your video, so I sealed up the brake light and the two larger tail lights with clear silicone, so fingers crossed that's solved the problem. Keep up the good work

Most helpful how to fix water leak out of all the many I've watched

Our daughter's car is driving her crazy. Now we know how to fix it. Excellent video!!

Thanks for sharing - this could really help me as I have a 106 which is leaking in badly at the back on the passenger side. My husband keeps saying, ' get rid of it' but I love this little car, no tax, low insurance, low on fuel and easy to park. I can get all my cash carry stuff in it if I put seats down. So I will definitely investigate the light fittings - thanks again.

Oh what a relief. Fed up with mouldy rear seats and having to put towels in the boot!! Garage looked at twice, but wants me to have two new light housing units fitted. :( . Going to give this a go. Thanks so much for a very clear and informative video.

My Aygo had water leaking into the boot but fixed it after doing the same thing but on the top brake light, love the channel, im watching all your repair vids even though my Aygo hasn't got those problems, you never know...

WOW videos are great watched them all as the saying goes you learn something new everyday just done what you said in the video, to be on the safe side what did i find drivers side wet, SO A BIG THANKS FOR ALL YOUR HELP AND VIDEOS and better still the money you have saved me not sending the car to the garage.

Great video tip to solve the water leakage. I think another alternative to silicon sealer would be to use Plumbers Mait it would also work great to seal the lights from water leaking in and its a proper water repellent sealing compound and the bonus it doesn't set so the light lens can be removed for changing the bulbs without it being glued down by the silicon method to the car 👍

You could also make new seals , for the lights, with denser foam and glue it on. Use the old seals to cut to shape. Good video as these cars are prone to leaks at the back .

Aha..... guess what we'll be doing at the weekend!!! Been scratching our heads to work out where it might be coming in from! Cos we never use the back seats we hadn't even noticed how much water they'd soaked up from the boot until we needed to carry a passenger... then the investigations began... boot was soaking!!! Annnnd now I know why my windows were always running on the inside!! Sealant purchased and we'll be doing this at the weekend! Thanks for such an informative video... I'm confident this will solve my problems!!!😁

Thank you very much for your helpful video. I had water in the boot and damp rear seats. I have siliconed my rear light seals and just waiting for the silicone to set. No surprises thanks to your handy video . Merry Christmas.

Very helpful, I have exactly the same problem on my daughter's car and this should help sort the problem out without breaking the bank.

Glad I found your video as just been quoted £900 by the dealer to fix the exact same issue.

Brilliant video thank you and just frustrating you have to go to this trouble for this car in the first place. Very clear instructions and really appreciated.

Mine was supposedly fixed on a recall. It's now worse than it was before they "fixed" it. Going to do it myself using your method. Cheers mate

I'm currently having the same issue with my 107, so I will be doing this tomorrow. Thank you for this video, very easy to follow.

Good video, think I’d have changed the bulbs while it was out though. Caravan dealers sell non setting mastic sealant in tubes or rolls, it would be perfect for this job !

Nice video (again!). Noticed today my daughter's C1 right rear light cluster has about 2" of water collected, probably after the monsoon we had on Friday! Left hand carpet a bit wet too so will follow your steps to cure both issues.

My Wife has had her C1 from new within 8 months she was complaining that the car was steaming up and felt a bit damp, it was mentioned to the dealers but they said they couldn’t find anything wrong and told her to use the heater more often. A month or two on and after a heavy rain storm the boot floor was soaking wet. Back to the dealers and it was fixed under warranty, problem was the high level brake light gasket had failed the water comes in on the left hand side (near side) all the way down behind the head lining and trim arriving onto the boot floor under the carpet. Easy to miss in the early stages as small amounts are soaked and dispersed in the carpet. Today six years on, water in the car again, the boot carpet soaked but this time the parcel shelf was also soaking wet. I thought I’d investigate myself, took the carpet and parcel shelf out, dried them in the house, folded the back seats down shut the tail glass and ran a hose pipe over the roof . Watching from inside the car I could see the water getting past the main rubber seal at the top which explains it getting as high as the parcel shelf, there was also a smaller amount getting in through the push button assembly at the bottom and onto the boot floor and a tiny bit coming in from that high level brake light again. From the outside with the tail glass up, a few conifer leaves stuck to the rubber between the glass when closed was all it needed to allow the water to get in . Dirt around the rubber also slowing down the flow, how did the designers think this was going to work,the rubber uses all the metal seam so effectively blocking the water channel you would see on other cars. After a very detailed clean I have this working but will need to keep on top of this to keep the rain out. I checked out the light clusters as per vides but they seamed ok, the high level brake light that had been replaced by the dealers is stuck to the car so I can’t get it off without damaging it, looks like some sort of black windscreen glue so they mustn’t have been happy with just fitting just the original gasket. As it’s just a tiny leak in this I will pipe in tiny amount of silicone,masking off the car, hope we don’t need to change a bulb but if we ever do the fitting is a goner anyway due to the dealers glue. Thanks for your information we still like the car and will persevere.

I just got an 107 today, I find the video very helpful..

The space for the spare wheel was full of water on my C1 when i bought it, i newer got it fixed during the months i owned it. Just drained it with the plugs mentioned in the video. Found a 2008 107 with only 24000 km on the odometer instead and i will definitely seal my car up before i get an issue with water. Saw an other channel where they put another foam gasket on the metal side so there was foam against foam when the light was reassembled.

Thanks, had this problem with my friend's 107 and fixed it with help from this video. Garage (official Peugot dealer) said they had to replace the rear light assembly completely... Nope.

i fixed the leak problem 😃 ! very helpfully your video! Thanks a lot ! 🙏

Thank you from France for this very useful video ! :)

Great video, thanks. I've had a leak recently and was struggling to find the exact cause. This video was easy to understand and I'll get on the case of repairing it

Excellent video. Thank you so much. My 107 needed this badly as it was leaking from all 3 lights!!!

Great video , thanks. I sealed the foam behind the light clusters some time ago and it wasn't a complete success. I've done the top brake light as well though I'm not sure that was necessary. With our car I think the culprits are the air vents behind the bumper. The seals were pathetic and water running down past the light cluster will run round and under the rear window then pass down and should go around the air vents but I reckon in our case it was getting in there.

Grande Punto 2008 similar design with sponge. Used clear silicone. Much better but still a little trickle down the side but minimal really to what it was like before. Went to take the light off the sponge stuck to the car! Glued it back on the light back and reapplied silicone. I may try the White plumbers paste you mention in the Focus video if it persists.

This has just happened on the Mrs car, we thought it was because of the recall last year, where they replaced the window and seals in the rear, just rung the garage up and they mentioned the seal around the rear light, its mainly on the passenger side on the rear, but thanks for this i will seal them all over the weekend and that should do the trick.

Great tips and techniques - thank you.

I had to go through this twice, finally it worked out fine. Thanks!

My wife's Citroen C1 has the same issues and I suspected water was getting in through the light clusters. I'll give your fix a try tomorrow! Cheers!

On a Peugeot 308, I applied silicone to the foam light seals and those on the air vents under the rear bumper, but still water getting in. Also, need to look at leaks around the front windscreen / wiper scuttle. The car is a nightmare for keeping dry and full of crap body finishing.

Safety recall- I watched the video yesterday and was all set to give it a go and then today I received a letter saying there was a safety recall- to do with the hinges on the back window not being correct and could be letting in water,vibrating and a possibility of the window coming free. So it's being booked in to put right .

Thanks for the video....I was thinking it may be the tailgate rubber seal but now I shall have a look towards the lights

Wow! I never thought of that. I was looking in the wrong place. Thank you so much. Merry Cristmas.

Such a common issue, oddly they never bothered to correct it with better seals. Other cars have the same design flaw. Thanks for sharing, doing this fix right now on our C1, as the in car swimming pool is no longer needed.

Nice. They all got the same problem ^^ I just removed my 3rd breaking light and just put some duct tape over the hole. Then left the car outside for 2-3 rainy days and checked every day the boot for water incoming. It was pretty dry, so i think main problem is the 3rd light and the others are just the "bonus". Also i saw on the 3rd light, that it is pretty much pressed on left and right, where the screws are, but got a little, just a tiny, hole on the mid section. But i'm stil aware of "glueing" the light to the car, as you need to remoe it every time a lamp is broken. I'm still working on a nice solution for this.

how exciting it is to have car knowledge! If l had been a man l would have trained in car repair

Thanks for this video,I have the same problem as you ,so I`m going to have a bash at it myself.I recently changed my front break pads and discs thanks to your other video and the car just sailed through its M.O.T. Keep up the great work!

Hey... thanks for this... great. I've a Toyota Aygo... daughter was running it and kept saying for a long time that it seemed misty inside. Having just checked it out I found a good inch of water in the tyre well. I'm gonna do as you have.... but with plumbers Boss White jointing compound. It's like a maliable putty... ... that way it's easier come new bulb time. I'll see how it goes... if all else fails... bring out the silicone. 😊👍 Thanks again.

Spot on iam gonna try that on my i20 today,looks easy enough to do. Got a small puddle on mine..

another method instead of silicon would be a good thick spread of grease around the seal surfaces, that way it is still easy to disassemble to replace bulbs, great vid btw.

Brilliant. This pushed me to try and sort the leaking car out. Thanks

Great information. That was very useful and a great test afterwards with the pressure washer.

thank you mate that leak was doing my head in !

id use butilic mastic the kind you use under the kitchen/or for sealing headlights (the one in a roll) its flexible and creates a water seal , yet if you pry its easy to take off in the future

My Toyota Aygo which is a similar design has the same problem, I never understand why they don't actually put a rubber seal between the chassis and actual light? Anyway your video is very helpful. Many thanks.

I have owned my Aygo for 12 years and chased this leak, it got worse with age, I found that the leak got worse when snow was on the roof, a clue, I found the high level brake light, the oval one above the rear window was at fault, If you look closely at the top of the light and the area it seals against, you can see a gap where the foam seal has shrunk and would allow a large amount of water in behind the roof liner, Either the red plastic of the lens warps over time or the foam seal shrinks due to UV, I took it out cleaned both sides put masking tape around the light and put a bead around where the light would sit, Just the top half of the light should be enough as water normally doesn't travel upwards, I then lightly screwed the lens in position and used a lolly pop stick to profile the silicone, Then when it dried i could do it up to "squish" the sealant for a better seal, When i bought my car in 2009 i knew about the reported leaks, It was not clear where the leak were coming from, but that high level brake light looks like it was the reason, on Aygo at least, The Pug, and Citroen have the same high level light, It would also make it look like the rear lights were leaking as the water would flow past the rear of the light clusters to make it look like that was the fault, Great video as always, hope this helps someone as left it will start to send your rear seat and seat belts mouldy, I also pulled off the sodden recycled fabric off the back of the boot carpet and threw it away.

Top class videos on this stuff!

Good informative video. I am going to give it go. Thanks 👍

I’ve got the FlexSeal ready to tackle those 2005 Buick LaCrosse tail lights! Thanks (and I’ll check sunroof drain tubes while I’m at it)!

Thank you. This helps me. Having the same issue with water getting in.

Thanks for the video. I've been looking at the Peugeot 107 / Citroen C1 as a little cheap runaround. WAWAW

Cheers for this. I'm hoping it will solve a similar problem with my Fiesta Zetec S.

aynen benim arabada da aynı sorun vardı bu video sayesinde çözdüm (peugeot 107 su alma sorunu)

Very informative video thankyou

Really helpfull! Exact same car, exact same problem here! Thank you ever so much!!!

I’m here after a £300 new immobilizer and £400 Toyota bill all because my boot was full of water. Even worse they’ve quoted me £600 for new seals to which I’m going to give this video a try

Thanks for the vids,I’m subscribing - your content is brilliant and I’ve passed on links to them.

Thnx for the video, helped me out a lot

Nice job, going to sort mine tomorrow 👍

Brilliant video, can you not buy a separate seal,? Will anyone DIY silicone work?

The idea is correct, but you can do better. Silicone should be allowed to dry, then collect back. Even dried silicone will be elastic and resilient. And the next time you replace the lamp, it will be possible to remove and reassemble it without problems. I'm going to do it that way. If you immediately glue after you smeared with silicone, then it will be impossible to unglue. Or, most likely, you will remove the lamp (lantern) and the native seal will break. And each time you have to smear with silicone again. Good luck! Идея правильная, но можно сделать лучше. Силикону надо дать высохнуть, только затем собирать обратно. Даже высохший силикон будет упругий и эластичный. И при следующей замене лампы можно будет снять и обратно собрать без проблем. Я собираюсь это сделать именно так. Если сразу приклеить после того, как ты намазал силиконом, то потом отклеить будет невозможно. Либо, скорее всего, ты снимешь лампу (фонарь) и родной уплотнитель порвется. И каждый раз придется мазать силиконом заново.Удачи!

I really want to fix the leak in my Aygo, but if using silicone, what happens when it is time to change the light bulbs? How will I remove the headlight? (will it not be stuck to the metal?) Thank you for the help!

Thanks man, I`m going to try this on my 107.

i love your vids! i've noticed this on mine yesterday! thanks so much for what you do! MERRY XMAS TO YOU AND THE FAMILY

what i do with these is clean behind the light autoglym it so the water runs off it instead of slowly running down it then use heavy grease round the lamp foam to stop it getting in so light comes out easy agian :D or use red never dry sealer altho its expensive

Well explained Bud.

Great video. My mrs 107 is wet through so will give this a try. UTO!

I would've put a smear of Vaseline on the body part (or grease). The silicone would set and take up the shape but when set, it wouldn't stick to the body and tear the foam.

Really useful video

I used gasket on a tube. it dont stick as hard as silicone, pro tip right there :). but the foam looked so "dodgy" that i covered them all over withe gasket on a tube. i still got a tiny leak but that becouse one skrev does not work, maybe a bigger one can grip the damaged plastic hole? as you propably guessed my native lanuguige is not english.

Good job !

Got same leak in my car been wondering where coming from . Will have to try this my boot on driver side wet . Also has anyone had leak on the inside light think it’s comeing from Ariel .video very helpful

good morning, i followed your interesting interventions on peugout 107 and i would like to ask you how to repair srs air bag spy exploded steering wheel and seat belt pretension store i would be very grateful to help me to visualize the sensor and the cable behind the front bumper thank you very much

Hey good explained video. But... Did it solve the problem? Or did you also have to reseal the vents behind the rear bumper? Best regards from Germany

While you're on with it, they leak from eye level brake light and the boot vents under the bumper.

Nice one, I'll try that next day off

Great video which I will follow and apply on the wife's C1 but we also have water inside the car mainly on the passenger side rear, the carpet is soaking so would the water getting in the boot be working its way into the car as well do you think ?

Thanks for the video. Is it possible that this problem would also cause the water to run into the main cabin? I'm seeing it in the footwell of the rear seats and by the sides of the front seats...

aysun ay Hello. Thank you for the video. Could you please tell what time of seal you use..? Water proof or another time, if you can give an example of make please do that I can look for it as I have no clue..? Thank you

Yeah, the biggest problem with these leaks is that when you get in the thing on a cold morning there's more water (in the form of condensation) on the inside of the screen than on the outside. Stop the leaks, make sure the other seals are ok, and it isn't a problem.

Hi there thanks for video 🙂because of the leak in the boot my back seat bench is damp do you have a video on how to remove so I can dry it out many thanks Pauline

I try use vaseline instead of silicone. And also remove bumper and seal off the 2 airconditioners holes.

I've got a leak have the spare wheel well slowly filling nothing major ...but the rear passenger footwell had inches deep water after all the rain and snow ....car is parked on an upwards facing incline so doubt it's a rear light issue any other ideas at all ??? 👍...it's a 5 door 05 107 btw

I own the Citroen C1.....thanks for the video

So not the actually seal needs replacing.. just a bit of silicone on those areas should sort it you think?

thx Really help full very good demo

Is so much cheaper just to buy a replacement foam and replace it. Is a standar air polyurethane foam with 12 mm thickness and cut by size. However I am interested if there is any othe cause of this happening on a Barlingo B9...

Hi there Would spraying silicon spray over the seals work to repel the water / or sticking some self adhesive sponge seal on top of the existing one ? Many thanks 🙂

Great tips

Sorry for all the questions.. should I use a silicone lubricant before applying
