      The seals are still supple, but they have the "cat tongue" feel to them again.

      I think you identified the key criteria, which is that the seals are soft, supple, yielding, and will conform around the top of the windows when the windows are lifted up.
      When seals are dry, they are firm and resist deformation. I don't think visual appearance (shiny, etc.) is significant.

      I've heard a lot of good things about www.1stvwparts.com. They don't advertise here on Vortex, but the parts manager there is a member here on Vortex. It seems that the company is actually a VW dealer, and they are creative enough to run an Internet parts business on the side. Based on what I have read in all the other forums, I think you can buy there with confidence.

      I mentioned this to 1stVWParts.com, and they said to me that they ARE a banner advertiser already
      Their banner is also listed in "Current Advertisers" page.
      just wanted to set this straight...
      BTW, they had a good price on Krytox, below MSRP from VW (as are all of their parts)
      That was also the cheapest source for VW Eos splashguards.

      Michael (and all)
      Following my post of 2 March my Eos was lubricated by the dealer today. They picked it up at 8am this morning and have delivered it back - a nice touch, even if they are only 1/4 mile away !!
      I haven't seen the car yet but I spoke to the Service Manager a few minutes ago. He told me that the procedure in your original post was followed carefully and he has warned me to expect some residue to appear over the coming days - they have wiped off what they could see. Judging by your comments about residues, that can only be a good sign.
      I can obviously post again once I've seen the car (I may not get home in daylight hours today!!) and I'll let you know my impressions. The SM did invite me to phone and ask them to collect the car "every couple of months" for a re-application if I wanted (he has a half bottle of oil left) - I'll see how things go over the summer.
      All the best.

      Peter,
      Good to hear your dealership is treating you well.
      Obliviously you will keep us posted, but we are all very interested to hear how the seals perform during the next rainfall.
      Hope it all works out.

      Hi Peter:
      Wow, I am honoured that a VW service department would read a post that I wrote for the purpose of getting direction about how to carry out a procedure. Please tell your service manager that if he or she has any suggestions or criticisms to improve the information contained in that post, to please write to me (click on my username to reveal my email address).
      If you do get some residual lubricant dripping from the roof, you can remove it easily either with a cotton facecloth that has been dipped in windshield washer fluid (my favourite technique, because it is quick and easy), or, just wash the car with normal car wash soap and water - presuming, of course, that the drip is on the outside of the car!

      thanks guys - will post again after the next rain (this is Glasgow so it ain't far away !!)
      I'll pass on your request to the Service Manager, Michael and ask him to e-mail any thoughts.
      On a very quick inspection of some of the seals tonight, I thought the rear sunroof seal still felt kinda rigid to the touch, whereas the side seals were nice and soft. But hey let's see how they perform - I'm just glad that the SM at the dealer is onside and keen to help.
      Cheers

      Hi Peter:
      That's normal, in the sense that different seals have different amounts of 'give' in them. By example, the seal that runs vertically up the forward edge of the two rear side windows is probably the seal that has the greatest amount of 'give' to it - it needs to have a pretty wide tolerance. On the other hand, that rear roof seal (the one just above the back window) doesn't need much give at all, because the assembly tolerance for the two roof panels that it joins is very tight.
      Be grateful you can expect rain in Glasgow - we had half a foot of snow in Switzerland today.

      I just had a scary phone call with the parts department of Martens VW of Washington (DC). For grins, I was calling for the price of a bottle of Krytox. The guy at the parts desk quoted a price of around $71 and said he did not have any in stock. He then asked what it was for and I told him it was for the Eos roof seals. He then said that they used an aftermarket product He had no clue if that product contained krytox or was safe for Eos roof seals....
      On another note, what, if anything, have you done to prepare the seals for the krytox? Washed them? Wiped the white stuff off, then apply?

      I am hoping that the price of the VW special lubricant (G 052 172 A1) will decrease in the near future... perhaps quite soon.

      When I did mine the car was brand new (1/2 hour after I took delivery) so I just applied the lubricant to the already clean, dry seals.
      I don't have the owners manual in front of me, but I believe it recommends cleaning the seals before applying the lubricant. This to me would be common sense, it would be advantageous not to be working dirt and foriegn material into the pores of the seals.
      I find that after washing the car the seals are wet enough that a quick wipe with a soft dry cloth will likely clean them up well enough. unless they have been subjected to unusual amounts of dirt and grime.
      I also believe that part of the routine service schedule laid out in the owners manual calls for cleaning of the seals by the service tech at certain intervals. I can't confirm this right now, but will check the owners manual tonight.

      Kevin:
      You are 100% correct with your observation. I am not sure if the owner manual actually suggests that you wipe the seals clean before you lubricate them, but the Eos Repair Manual makes this point very clear - it recommends that after washing the car, you first wipe the seal clean with a damp, lint-free cloth (e.g. a microfiber towel), then let the moisture evaporate, then lubricate the seal.
      Thanks for bringing that to everyone's attention.

      Kevin,Michael hi I just want to ask if the cleaning process of the seals that you mention are also in the European manual and if certain weather affects the seals more or less(Hot or Cold climates)....Andy

      Hi Andy:
      I believe that the European owner manual also makes reference to maintaining the seals. Have a look in Section 3.2 (booklet 3.2) of the owner manual. The page number will likely be different than the page number in the North American manual, but the information will probably be there. In fact, I think someone has already posted the page number for the European English owner manual elsewhere in this same 4 page discussion.

      A while back, I posted that I have had my sunroof seal replaced already. It was being pinched near the driver front edge. Also I had a leak, dripping on my left thigh during the snow storms. The regional rep inspected it, drenched the car with water for 30mins. according to the dealer service manager, and guess what, NO LEAK!. However, this inspection was done when the outside temp was about 70. So, if it isn't leaking at the pinch site, do you guys think that when it is very cold, snowing, raining, that there may be so metal shrinkage somewhere else along the line that is responsible for the leak when it is cold? Also, I have lubed the seals like crazy. It hasn't leaked again yet since the sunroof stuck in the open position and I had to take it back for that. Maybe the sunroof was out of alignment, I just don't know.

      I followed your directions and great pictures.
      Used my $87.00 bottle of magic on all of the seals... stopping the roof operation midstream (like you said) even though the owner's manual said to never do that. See how much I trust you !!!!
      Finally, the sunroof seal is not pinched anymore. When I purchased my Eos last August, the dealer said that was normal. Guess what... not so no more deformed seals!!
      Keep up the good work. I really appreciate all of the valuable information.

      The warnings in the owner manual against stopping the roof midstream are there for safety reasons only, not for any engineering reasons related to the roof. If the roof is stopped halfway through its cycle, it will eventually move on its own accord (by gravity) to either the fully open or the fully closed position... unless, of course, you manage to stop it right at the 'sweet spot' in the middle and it can't decide which way to go.
      The authors of the owner manual were concerned that someone might get injured if the roof started to close on its own, without any warning.
      Which means - when you stop the roof halfway through its travel to lubricate it, be alert to the possibility of the roof settling on its own to either fully closed or fully open. My experience has been that if it does not start to move on its own within a couple of minutes, it probably won't move on its own. But, your mileage may vary, so be alert. It doesn't move suddenly - it moves kind of slowly, however, you don't want to have your arm or some other part of your body stuck in the wrong place if it starts to move.

      A couple of weeks back, I lubricated my roof seals with the GPL205 Krytox grease (thanks of course to the valuable information found on this site). The results are as follows:
      Almost immediately, the grease, which at least a little of remains on the seal, catches road and environment "dust", including fine road sand. This did not make me happy, as a) it looked bad, and b) I felt it would not be good for the seal for sand and dirt to be squeezed between the glass and rubber. I have wiped and washed the seals a few times since then, which removes most, but not all, of this held dirt.
      I have also had one "pinch" since then, with very few openings (crappy Spring so far here in NY).
      I will say that the stuff is pretty amazing. I kinda get the feeling it will never wear off, since it has retained the exact same hydrophobic properties as the day I put it on.
      Haven't had any leaks before or since (except in my trunk, but that's in another post).
      Just curious if anyone else has had the dirt-trapping problem with the grease, and any idea how to remedy. Do you think I simply left too much on? I did try to spread it thin with my finger...
      Thanks.

      Do you think it was maybe because your application needed to dry for an hour (or some period of time) before you took the car out for a spin? I haven't used the lubrication yet so I'm not sure how "wet" it is to the touch right after application or an extended period afterwards. That's the only thing I could really think of.

      Hi Daniel:
      I think the specification for the lubricant calls for VW Part Number G 052 172 A1, which is an oil, not for a grease - perhaps this is the cause of your problem. The oil is pretty quickly absorbed into the seals of the car and it does not attract dust once it soaks in (about an hour or two).
      We had a pretty lengthy discussion about different forms of lubricant that are sold under the trade name 'Krytox' a couple of months ago. 'Krytox' is a trade name for a very broad range of lubricants made by DuPont - for the Eos, we need to use the specific lubricant that is provided by Volkswagen, not any other lubricant that might be sold under the trade name 'Krytox', and most especially not a grease.

      Can we make this topic a sticky? I keep referring back to it and have to search for it each time. I'm sure this is of great value to the other forum members also.

      Now would be an excellent opportunity to familiarize yourself with the "Table of contents" sticky thread at the top. An enormous amount of volunteer work was put into creating and maintaining it, and it provides a wealth of information. It will open a new world of understanding to you. You will find this thread there as well. Its in the 4th/technical category. Your searching days are over.

      This thread was sticky at one point in time, but PanEuropean brought up a good point. If threads are sticky too long, people tend to ignore them...you know, familiarity breeds contempt. Another problem is that sticky threads do not move as people add new posts, so your odds of getting a good response diminishes. Threads have gone in and out of "sticky" status to keep things interesting. Maybe it will be sticky again, who knows.
