Toyota Avensis T27 ticking sound

[BNZ-1992]

Hi everyone,

I just recently bought a used Toyota Avensis sedan from 2010 where the odometer is around 165.000km. The car is an automatic and drives very well. Though I have two concerns that I’m hoping someone can help with:

1. Ticking sound from engine bay (I will attach video). I have trouble figuring this out and have booked an appointment with the shop to locate and hopefully fix it. Does anyone have an idea of what it could be?

2. A lot of wind noise from A pillars at highway speed. I’ve read something about the smaller windows and their seals being the cause of this. Can anyone verify and if so please provide how much this costs to fix?

When I turn on mine there a anoying buzzing sound and comes threw my tweeters on my dash it's annoying as hell also I must take a video also show .I'd love to stop it as it's like a anoying ground loop noise threw my speakers

This is what I did to diagnose the wind noise from the A pillar area:

That proved it was the seal around the front quarterlight window (the little window at the front of the window in the front door). My local Toyota dealer replaced it under warranty, so I do not know how much it cost.

If you have the Valvematic petrol engine, then at idle the vacuum pump will be heard. The vacuum pump is located on the end of the camshaft at the transmission end. Due to the nature of the way Valvematic engine works, there is not enough vacuum provided for the brake servo, just like diesel engines. Because the petrol engine is not as noisy as a diesel engine, the vacuum pump will be more audible.

I made post on this a few years back -

I see. The car has a 1,8 VVT-i engine so that may very well be the sound you mention. It just sounds unusual. Based on the video you’d say it’s that vacuum pump?

I’ve also got this weird almost whistling noise. Any idea what that could be?

I must say you have a very nice car, the engine noise is the plastic engine cover you need to play with diy rubber feet or so, the whistling noise probebly the wheel bearings....

I have played both videos. The first one sounds different to the vacuum pump. You need to the bonnet and record the sound closer to the engine. Listen close to the source and point to where you think the sound is coming from.
The whistle sound I am not sure, but your car has CVT, so it could be related to that.

Here’s a video from engine bay. It’s more difficult to distinguish the ticking sound from here, but it seems to be located further back toward the cabin and a bit lower towards the ground.

I don’t believe it’s the engine cover. Just tried removing it and the sound is still there.

as to the whistling sound, it’s mostly present when decelerating. Would that also indicate wheel bearing? I’m suspecting something related to the CVT gearbox as Konrad also mentioned

Hello

I have a 2009 Avensis 1.8 VVT just like you, recently bought it. The wind noise was driving me crazy but I did a lot of trial and error and fixed it eventually.

What I did was buy some liquid gasket (black) which I then applied around the quarterlight, following 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 in your home. Use some painters tape to avoid getting gasket 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

Many thanks for your tip/advise UlleB!

I'm not sure if you removed the original seals before applying this gasket. Or did you apply it on top of the existing seals?

In my recently bougth 2009 Avensis I've much more wind noise compared to my 2006 (latest T25 model) Avensis.

I just applied it on top. You can use transparent silicone as well if that's cheaper and easier for you. Since doing this I haven't had issues with wind noise coming from those areas of the car so I'll say it's fixed. Obviously the proper way to do it is buying the gaskets from Toyota and fitting them but in this case I fixed the problem for a fraction of the price and I don't really care that much how it looks as long as I'm not selling the car.
