New Car - Leaking Boot/Water Ingress
« on: July 04, 2013, 04:03:17 pm »
Hi Guys,

I've explored the web both through Abarth and even normal Fiat topics but can't seem to find somebody in the same situation. I opened my boot one day and looked under the liner to find quite a substantial pool in my spare wheel well. Not investigating any further, I dried it up just in case I'd been over enthusiastic with the hose one day.

Now that it has been raining, I looked again to find another pool. This time I traced the water behind the left side wall liner right where the rear light sits. I removed the liner and found water trickling between the skin (see picture with added water droplets!). I've had a look behind the rear light and can't see anything that would suggest water entry though here. The only other thought I had was the plastic wire cover at the top left of the boot but that looks all ok too. It's definitely not the windscreen washer pipe, as it only happens when raining. Can anyone suggest an alternative? The car is a standard Abarth 500 and has covered only 1000 miles!!

    A leak in the boot is almost unheard of on this forum. May I suggest you go back to your dealer, being a new car it should be covered under warranty

    I thought that might be the case :(

    I've got it booked into Bauer Millett's but not until 15th, wondered whether it was something simple I could tackle myself.

    I was thinking the pins that hold the rear light might be letting water through, until you said otherwise  ???

    Have you tried leaving it parked in different directions on a slope? might help track down the source   ;)

    Not heard of boot leaks on the 500 before hopefully something simple when the dealer takes a look  :thumb:

    I always park upwards on a slope allowing the water to trickle down I guess.

    Judging by its drip position, it has to be coming from above but actually from the car itself and not the boot door as its between the skins.

    Maybe something to do with those black strips/runners?

    Or possibly the rear quarterlight seal?

    I would say its more then likely coming in through the light fitting, you could test this by getting the hose out and directing it to different parts of the car you suspect it could be starting from low to high and checking each time

    Could also be from the roof, where the roof bar fitting is. Maybe there is a seal underneath there that is not located properly.

    Best bet is get it sorted under warranty. The more you mess about with it, the less the dealer is going to want to touch it.

    Get a equivalent loan car F.O.C. and ge them to sort it out!  ;)

    why dont you sit in the boot and have someone hold a hose on your car for a while and see where its coming through from?

    but yep do what the other say and send it back to the dealer, they will probably just do the above anyways and replace and seals.

    Hi all just a quick question did anyone get a solution to this problem as my fiat is leaking water from between the 2 skins as shown in the photo! The rear light is fine it seems to be coming in from higher up the body of the car. Thanks kev price

    exactly the same issue, driving me mad lastfew days. my observations below Kev, tried to put pics on here but says too big.

    Hope my ramblings make sense bit in essence its leakinh between the skins as you say in the boot behind the light.

    OK I am baffled and frustrated, and also freezing cold 3 days in sub zero trying to find a leak in my daughters 500. Any thoughts on my observations and fixes below grateful welcomed.

    So initially noted that the spare wheel well was full of water and I mean full, so drained this and removed side carpets etc. to notice that drivers side boot lining was wet. Watching over the next few days I moted it dripping from behind the bottom right cut out at back of boot and dripping inside then running down into the wheel well.
    Naturally I removed the light cluster and sealed the grommet to test. Fault remains.  Having noted on here another member had suggested the antenna base I investigated that. Removing the headlining I noted huge amounts of condensation  up on the inside on the roof and inside of the panels/ cross members. If the antenna had been leaking for some time and that the car gets little use the condensation seems to be a reasonable result of these circumstances?
    Antenna base sealed with all-weather sticks like **** and tightened down.  Fault remains. Next step bumper removed having seen further articles about sealing the bumper brackets, so this has also been done.

    So as all side linings were out and back of headlining dropped I sat in the boot with an assistant with hose of full all over back of card. Nothing visible from underside of antenna base so ruled out.  Now here is the nuance, we couldn’t seem to replicate the fault. That is to say I expected to see water running from the cut out at the back of the boot but no. well not for a while then a trickle.

    So next step remove the black roof strips and examine the seal underneath, given they were very difficult to remove and that I can see no visible corrosion or breaks in the seal this seemed unlikely. To again remove this I ran seam sealer down the gullies either side and allowed to dry, fault remains.

    Next steps was an endoscope. I noted water trickle between the bowl shape panels behind the lights so under the out skin where the light sits but on top of the similar shape skin under that, this is where it then drips through the cut out. So how is it getting there. More research with the endoscope revealed that if the hose was placed over the top little black grommet where the peg on the rear lights fits water ran behind this. At last I thought, but the plot thickens. We covered the grommets with gaffer tape to isolate and continue investigating ( by the way £9 for n ew grommets’ from Fiat). Nothing coming in here but still a trickle in said area. OK we removed the rear side panel to look behind the speaker. Removing the sound deadening from over the wheel arch revealed the bottom of it was soaking wet.

    So one assumes that its getting in above the wheel arch and running either or in both directions? a reasonable assumption.
    Endoscope in hand and assistant spraying the window area nothing! cant replicate the fault , but then a large run of water from what appears to be below the back corner of the rear quarter light.

    Then it stopped and nothing. Keeping the endoscope in that area reveals a small drip now and then from around the area under the rear corner of the rear quarter light window, but running on the inside skin not the outside one? Go figure.

    OK so looking at observations and summing up my thoughts does anyone have a view? As a temporary measure I removed the bumper again and drilled to small holes under neath behind the cut out to allow water out , I blocked off the cut out temporarily with plastic to guide the water out, the holes can be sealed with grommets after.

    There is still loads of condensation left in the car and I wonder is it this that’s till running down? If it was just the light grommet given the spare wheel well  was full then that would cause a lot of condensation? Trying to dry it out in cold damp weather is just about impossible but leaving the back seats out for a while and the side panels seems prudent.

    I’m not reading too much if anything about the fixed panoramic roof leaking and there is nothing inside the cabin so im thinking this is also unlikely?

    In the picture below of the front side of rear wheel arch where does this lead? There seems no drain hole to allow any water ingress to escape, I also not there seems no permanently open drain holes on the sills on a 500?


    In removing the rear seat belts the bottom anchor bolt sheared off which I also read is a known issue on a 500 so need to get someone to drill that out.

    Frustrating indeed.

    I've just spotted a similar issue, with a small leak in the boot area, appears to be coming from the left side inside the panel behind the seats, possibly from the rear window. Not a major leak, just drips. Had the car a year and only just noticed that the underside of the boot mat was wet on the left side when looking for the wheel nut socket. Still to investigate properly, but might just pass it back to the dealer to look into under warranty.

    Thought id solved mine but still dripping, I just cant see how it can be the rear quarter window as its bonded from outside and the water would need to goover the lip. I cant see any evidence of this from sitting inside with the paenls out and a hose on it. However it seems to come from a seam between the panels further back from the window in the rear pillar in line with the bottom area of the window.  Its an annyoing mystery. Kev who posted earlier suggetss the seam on the roof gutters under the black strips. Let us know if you get a result

    Thanks for the suggestions. When I get a chance I'll take a look, hopefully don't have to take it apart too much.
