My Permanent DIY Fix for Toyota Avensis T27 Wind Noise

[UlleB]

Hey everyone

Recently bought a 2009 Avensis T27 with the 1.8 VVT-i engine. After purchase I noticed a wind noise coming from the driver's side vent area. I did a lot of trial and error and fixed the problem eventually. I wanted to share with everyone how I did it since it was a bit hard to find answers online, I had to piece together a lot of information to find a solution. If you have the same problem as me, this will be the solution. Please note you can apply my fix to both driver side and passenger side, if one side is bad then the other probably is too or is likely to fail soon.

What I did was buy some £3 liquid gasket (black) which I then applied around the quarter light on the outside of the car. I followed the the original seal all the way around. This fixed the wind noise instantly. You can apply the liquid gasket the same way you would do using acrylic grout or similar in your home. Use some painters tape to avoid getting gasket material all of the place. You just need to apply enough gasket to make sure the small window is sealed all the way around. It dries quickly and you should be able to get results instantly.

To be 100 % clear I'm talking about this window where the seal seems to go bad on many T27s: https://imgur.com/a/Xw9RUL7

If you do get some gasket material in unwanted places it's no big deal. You can easily scrape it off with something like a credit card, it's very easy to work with. 

The material I used was this: https://www.autodoc.dk/ma-profesional/15078113?gshp=1&gclid=CjwKCAjwhJukBhBPEiwAniIcNcZEJt4nvIXYUtgq1s3ysHa86ai2gulIPXmIos982VJHN_NYCrRazhoCM_4QAvD_BwE

"Black Hi-Temp Silicone Gasket Maker"

There's also an OEM solution you can choose by having the gaskets replaced by Mr. T or a shop. I can however guarantee you that it won't be a £3 job, more likely 50 times that. It will probably look nicer.

Good luck and let us know how it goes.

I was a bit sceptical to start with but invested a few coins in some silicon gasket maker.

I applied it yesterday all around the triangle windows on both sides.

I didn't have the time to test it, but my partner drove the car on the motorway today and asked why is it so much quieter inside her car. Job done.

Thank you for a great idea.

I do have this noise too, so will give it a try, thanks.

Happy it helped you too.

So where am I applying this, around the front door quarter panel glass?  What do I need to pull out, or can I just pull it open to apply and that will do? 

The Avensis is relatively noisy compared to other cars in the class. I'd absolutely love to give this a go, but I don't want to make a balls of it haha

Apply it around the inside edges of this little window where the original gasket is: https://imgur.com/a/Xw9RUL7

If you, like me, don't really care how it looks then just apply the gasket liberally. Otherwise you can mask off the area to make sure you only get new gasket material on top of the old one. What I did was first to apply material and then I ran my finger on top of the material to make sure it got into all crevasses etc.

I'm thinking you can also apply silicone (black) and move forward like this. It's just about using whatever material you have handy and method you prefer. If you want to do a test first then apply duct tape around the area where the gasket is. This should also provide results.

Has anyone tried this solution yet and if so, can you share a quick picture with how the window is sealed?
