The glass which is the rear window on my 2003 audi a4 convertible has loosened from the cloth roof in the lower right and left corners. It has been glued a couple of times, but every time it loosenes again quickly. Water seeps in when it is raining. I have even been in touch with 3M to see if they have a glue strong enough to stand the strain from the roof going up and down. Tried one of their glues without luck. It only lasted a few days. Audi claims that a replacement roof will run me 5,000 USD... How can I fix this?
Well I went to Lowes and shopped for a construction adhesive. I picked PL brand Polyurethane Premium Construction Adhesive because it is (so they say) 3 times stronger than ordinary adhesives.
It is also water and weather proof
Bonds to wood, metal, stone, concrete, masonry, bricks, vinyl, plastics
It came in a tube (you know.. chaulking gun style)
How could it NOT hold glass to fabric??? Thats what I said to myself.. well when we have nothing to lose, we'll try anything.
I put a good bead about 3/8 of an inch in between the glass and fabric, waited 7 days and then razored the excess off the glass. Applied black permanent marker and I'm done. So, it's been about 2 weeks and it's holding well so far.
I'm a betting man, but I won't bet this is going to hold... would you?
I just had my top replaced due to the same problem (glass loose). Audi told me this was the first year karmann (I believe of karmann ghia fame) made the convertible tops and the 2003 models have had a bunch of failures in the 4+ year range. They also told me the newer tops last longer. Be careful if you get the top replaced, ask for Audi original. I didn't ask the repair shop for the true Audi top and got an OEM replacement. I notice there is no flat seam next to the rear window, so when it rains the water tends to pool up near the bottom of the glass and the top is wavy under the rear glass.

Look in owners manual,it will show you how to raise/lower roof with tool end of dash driver side
Once you have the tool the best way to reset roof is to manualy lower it and lock rear cover
Two people helps to lower as you have to lift front of roof and lift rear
When rear metal cover is unlocked push roof fully down and lock cover
The roof should then work with the switch
is the window snow or ice covered? if so, you'll need to scrape the snow or ice off of it. the wiper blade may only have frozen to the glass. after windows clear,try picking up wiper away from the glass and then turn it on. use your rear defroster to keep this from ocurring again. if none of this works, check for blown fuse under the dash. if this works,please accept my soltion and thank you for choosing fixya.com
try this,put the key in door and unlock/hold over key.windows will go down,then lock/hold over,windows will go up.this resets the windows auto trap mech.(kids fingers)if you still have a problem also try using silicon spray on the runners.NOT THE GLASS.....
I have the same problem and read that in some cases 3M Wind-o-weld has been used to fix it. I tried that, and as soon as I put the top down and back up, it pulled back away. looks like I'll be getting a new top
This has happened to my wife's 2004 A4 Convertible 2x's. I had to read the owner's manual several times to get the job done correctly (pages in the high 70's to low 80's) ...the following is offered from memory:
The handle/tool needed to accomplish the task 'manually' is located in the fuse box on the LEFT SIDE of the dashboard. A small flat blade screwdriver will enable you to pry open the fuse cover & gain access to the handle/tool. Slight twist the tool and it comes out easily. Tool is a "T" shaped handle.
Once you have the handle/tool IN HAND, simply turn the RED part (only) on the handle until it 'locks' in an open position. Leaves a small space on the handle. Can't recall if you go clockwise or counterclockwise, but it will be evident.
Now...move both front seats forward and tilt them to gain access to rear seat. Remove the ski boot cover in middle of the rear seat and put aside. Then, 'click' the interior boot cover panel down to gain access to a 'hole' (about size of a 50 cent piece) in the top of the boot space. This hole allows you to insert (upward) the above mentioned tool into a lock/unlock mechanism in the rear deck just forward of the trunk. The tool needs to be jiggled to go 'all the way' in...you will sense that. Once in, TURN the RED part of the handle to "LOCK" the handle into the mechanism. The tool will hang down by itself.
My approach is to 'store' the roof in the open convertible position first. The front portion of the roof should be partially forward as that appears to 'release' a lever within the roof's up/down mechanism to allow you to raise the rear window portion. Thus, lift (with that friend) the rear window portion up and forward (takes some effort). The roof now has a kind of 'clamshell' appearance front & rear. The front may even flop forward but tht's OK. This step exposes the rear deck.
Twist the tool to unlock the rear deck. It should click & release and a small space appears enabling you to use hands (that friend again) under it (the deck). Lift the deck up & back until the hydraulics kick in and keep the deck vertically open.
Now you are ready to tackle the roof & rear window for storage under the rear deck cover. Get a friend, if possible to help with the lifting...remember, this is a "Manual" job! Once here, gently push back & lower the rear window portion of the roof into the open storage area simultaneously followed by the remainder of the roof itself. Watch fingers for possible pinching in the levers, etc., during this part of operation
Hopefully you now have the roof & rear window stored in the area in front of trunk and be able to lower the rear deck to almost closed position.
If so, go back to the tool and twist it to 'lock' the deck in place with roof stored.
Remove tool from the ski storage area by reversing procedure above.
Now comes the "Moment of Truth"!
With the ignition turned on and car running, use the roof switch to bring the stored roof up and all the way to the closed position. Don't forget you must keep your finger on that switch until the operation completely finishes.
Then, reverse the process to open & store the roof for a good blow dry (drive)!
i can,t see why all these should need to be replaced,you need to get a more detailed report of what exactly they want to replace and for what reason in my experience dealerships dealing with roof faults will replace parts one by one untill the problem is fixed and surely the dealer should cover the cost of the repair if the roof faulted after only 3 weeks
I have the same problem with my 4 year old A4 cab, the seal has gradually broken over last 6 months and now the whole right & left sides of the window are exposed - tried glueing it myself with no success.
Audi tell me it is possible to have the window stitched into the fabric but I assume this involves replacing the original window with a plastic one and therefore losing the option of heated rear window.
I very much doubt Audi will cover the cost of a new roof once warranty runs out, I find it disappointing (but predictable) that they cannot simply re-seal the fabric to the window.
After reviewing the feedback on these postings I identified the problem them took it to my local car stereo shop. I showed them how by raising and lowering the trunk the signal went in and out. They fixed it for $60 by splicing in some new coax cable. It works great.
