    Hi folks, my door blade has just come loose at one end and I'm wondering do I need to take it off to repair it?

    I see this thread here has instructions on how to remove it http://www.audi-sport.net/vb/a3-s3-...ttempting-door-blade-removal-later-today.html
    But I'm not sure if I have the same problem as this thread. You can see a pic of mine below. The white plastic piece the the blade is attached to is still attached to do the door.

    Does anyone know if this thread is describing the same problem I have? Or did their white plastic piece come away from the door?

    I'm wondering if I can just put some sikaflex 252 sealant directly on to the white plastic bit without taking it off the door and just seal it to the blade?

    You can try glueing it but I'm unsure how long it will last. They're easy to remove. There are four bolts you access from behind the door. Two are covered up by rubber bungs.

    So do I have the same problem as the thread I referenced? I just couldn't tell if their blade came away from the white plastic part or the screws stopped holding the white plastic part.

    I tried unscrewing the two screws either end but my electric screwdriver was just wearing out the screw head. So left it for now.

    Do I just need to get it all off. Then seal the white part to the blade. Then screw it all back on again. That simple or am I missing something?

    Yes, just follow the instructions in the thread you linked to. Your screws are fubar'd by now, so probs need to drill them out to get the blade off.

    I had the same problem the screws seize and break out of the plastic as it's the end you can get some grips on it then drill the screw out. I glued mine then as an extra used a longer screw that actually bit into the blade which has worked for me. Been like it about a month so far and appears to be holding so don't hurt to try. I was a bit worried just dropping one new blade on might show a colour difference and other bits can use the funds more at the minute.

    I'm wondering how I just take the blade off. Do I need to remove any screws?

    It sounds like the four screws are holding the white plastic bit on. None of these screws go into the blade? So can I just pull the blade off?

    there are little fixing mounts on the door which the door blade slides onto.

    If you undo all the screws and open the door the door blade should slide a little towards the back of the car and you can then remove it to repair.

    It should unscrew and slide off as said above. But all mine had seized and the things they screw into come loose so a case of drilling them out.

    Yes, the problem you have is that the white nylon insert is coming away from the outer grey plastic moulting, which is what happens to these fixings over time. Essentially the rubber material between the white nylon and grey plastic perishes and causes the parts to separate. This is what had happened to my blade.

    In my original thread above, I used a self-tapping screw to re-attach the white nylon insert to the grey moulding, and then also sealed it in place with Sikalfex. Once dry, I then filed the exposed head off the self-tapping screw and re-attached the blade to the car with the original screws (which were luckily OK).

    It's been back in place now for 2 years and hasn't shown any signs of coming apart again, so I'd recommend following the same route.

    Drop me a PM if you have any questions & I'll try to help.

    As mine is only slightly off at one end. I'm thinking I will just do the following:

    1) Take out the screw
    2) Drill a hole into the door blade
    3) Put in a longer screw

    What you guys reckon? Is there enough in the end of the door blade to take a screw?

    Yes there is enough in the end of the door blade BUT in the long run it will only get worse as the reason it's done that is because the white nylon strip has started to unbond from the blade itself.

    Thanks. I think I will go for the quick fix for now and try a longer screw.

    When you say the nylon strip has started to unbond from the blade, I thought that the blade wasn't bonded to anything - it just slides onto the fixings?

    This is what I have done on the passenger side. Let me warn you the blade itself is made of a very soft plastic, so I used a longer screw with a blob of superglue on the end, and didn't over tight it. I drilled a small hole through the door hole as a guide aswell, it's still in place.
