Default Eos Roof & Water Woes

Hello all,

I've had my 2006 eos since last summer and it behaved very well. Loved the car, only mod was to add some daylight running lights.

Then it started...3 months of uk rain....then a warning, close convertible top. Okay, check boot, appear dry but smells a bit damp so decide to take out the panels. Discovered swimming pools both sides behide the ECU's (centre boot area dry as are the front swimming pools where the pillars are stores. While I'm at it notice the main rams are missing the circlips and pins about to fall out! Easy to remedy. Then notice the top latch is very loose, take off boot/trunk underside panel to tighten up and the underside ins completely saturated....how the hell, did it seep through the trunk lid?? Oh well, tighten up latch and dry the whole boot out. Tighten up the lights and treat the boot seals. Hose over and no water coming in now. (Fingers crossed!). Roof still not budging VCDS throwing a G558 sensor fault. Wonder if it because the ECU is playing up as showing signs of water damage, try a second hand one, clear fault but it returns.

So.....is it likely to be the sensor packing up....or a broken/wet wire or connector.....can see the diagram where the sensor is but man this is a mission!!! After reading many forums don't see many people actually getting in to fixing sensor issues, or have leaking boots as opposed to A or C piller seals.

I will fix this thing!

Well my leak was due to the boot latch being loose so not closing all the way, never heard of anyone else having that! Wish my ECU was the problem, I have a spare now. Will try and have another look next weekend, will try and uncover the bad signal sensor and check the wiring back. As for your leak, if it's coming into the boot but the front is fine will most probably be the C pillar seals, check out if you have puddles under the flaps by the rear seats! Good luck!

Question

Can anyone recommend a really good VW/EOS specialist in Surrey/Hants or Berkshire that can "fix" EOS roof/seal issues at all please??

Thank you

Angry leaking roof

hi my wifes eos went to garage today for the minor problems we had when we bought it ,leaking roof on the drivers a post which drips on leg ,annoying,also cam belt was squeaking ,so garage advised a new belt and water pump ,which we had to pay half as garage said was wear and tear,after 2 weeks dont think so,dealer said hed pay half.Got car back and soaked with hosepipe still leaked,beginning to think was this a good purchase ! So back to garage next week to redue leak.

Default Roof pump submerged in water!

Tried to put the roof down for the first time after a cold, record snow fall New England winter. Windows went down, everything stopped. Windows wouldn't go up, trunk wouldn't open. Dealer discovered the roof pump and harness submerged in water near the spare tire. Never saw signs of leaking as the trunk is dry. Dealer wants $2000 for parts and labor but have to find the leak first or it will happen again. spent two hours looking for leak, no clue. Now they say can't find the leak with the roof up but guess what can't put the roof down without the new parts!! And the leak happens when the roof is up so why do they need it down to find it? any suggestions. I loved my 208 EOS, until now. Only 64k miles

I don't know if this helps because roof and trunk leaks can be individual and a bit 'personal'. There rarely is a one fix all solution.

What I do know is the trunk seal at the front is rubbish. The sides are o.k and the roof seals should only let through small amounts of water if leaking. When you lift the trunk go to the front and check out the black channel that runs straight across the car. That is the 'gulley' that takes water off the roof of the car and sends it down 2 drains at either end.

I parked my EOS on front wheel ramps and had that gulley over flow into the trunk in just modest U.K rain. That is the ONLY time I have ever seen water in my trunk. Now that says to me that the seal running the width of the trunk at the back is poor because it only has to work when the gulley over flows.

You talk about the car being snow covered in record snow. If that gulley gets blocked or with thaw and freeze the drains are blocked, roof water can only be held back by that seal which I don't think is that good. The trunk is quite flexible and the seal is very long. Normally I would check seal contact with thin paper, but I do not know how you would do that on this seal and I don't think it is that good anyway as mine didn't seal. The best answer is to use a half top cover if the car is laid up outside in Winter snow.

If you really want to test that front seal with the hose, you must get so much water in the gulley channel that it fills to overflow. But I think water will pour into the trunk!

What appears to be a common problem with movement of the rear boot seal is documented in the following thread:

Hi, I followed your link Silvershadow but unless I am seeing photo reflections, I couldn't figure it out. My EOS 2006/7 Roof seals were replaced under warranty circa 2010. I have attached a marked up photo of what mine look like. If the black channel fills with water and overflows, the only thing stopping water entering the trunk is the seal along the top edge making good contact with the inside of the trunk lid all the way around.

Now I have had a second look at it I do think I could slip in some thin paper at that back edge with the lid closed to feel for friction all around. The reason I think snow might have caused this problem, is it is a key seal to hold back what could be a very large amount of water draining off the back of the roof. Other seals in the roof connecting components would probably produce much smaller leaks into the car.

OK - the seal I was referring to is a flap fitted immediately under the chrome [stainless steel ??] trim strip immediately under the rear window glass. This is the "flat strip" covering the boot rim channel on the LHS of the photograph.

This additional seal undoubtedly is one of the enhancements VW incorporated in the MY09 modified seal upgrade as a consequence of problems discovered after release of the Eos. The role of the flap appears to be one of sealing the gap between the boot lid and the car body to stop water running into the channel and forcing it to run across the boot lid instead before falling to the ground. I suspect this would divert around 80% of the water coming off the roof section at the rear of the vehicle.

With the roof up, locked and the trunk lid open I see no flap. But I will have a closer look. As far as I have shown in my photo, water runs down the rear screen, over a rubber molded strip at the bottom of the glass surround, then into the channel to go left and right into the drains.

The trunk seal at the back is only making edge contact when the trunk cover is closed. I haven't yet worked out if you can increase contact pressure. I do Krytox the new trunk seal and it has a nice firm springy feel to it. Most car door positions are set using the hinge bolts in oval holes, re-adjust the door lock keep, then check the 'shut' dimensions are correct to spec. and even. I'll poke around the shop manual for any adjustments on the trunk pivot hinges. But I suspect they will be marked with VW white or yellow paint!

..........The adjustments for gaps/shut lines are made at the lower bolts of the hinge.

There are also a couple of adjustable sprung rubber 'buffers', But I think those are just for the front edge. The objective would be to use thin paper and ensure even seal pressure all around. But I don't have any leaks yet!

Currently in Sydney till late next week so cannot photograph the flap seal to show it in more detail.

As always, one look will be better than 1000 words!!!!
