Boot of Toyota Auris keeps filling with water

krustydoyle

Well folks,

Bought a 2012 Toyota Auris recently and under the boot matt around the spare keeps flooding with water leading to a big build up of mould on the matt

Any idea what might be causing this?

Rubber seal around back door/boot.

Check for cuts or its sitting correctly.

There should be a rubber plug at bottom take it out until you solve issue at least water will be able to seep out.

It's been back to the garage to sort it and all but it's happened again.. I pull out the plugs to let the water out alright.. It's just so bad that I'm gonna have to replace the matt cos the mould is after building up a lot

Take the matt out and give a good rub. You could use likes of baking soda, mould and mildew or even vinegar(white) will help.

Give good scrub and leave out to dry should be able to save it.

Did they replace the seel?

Check for water around or inside the rear light clusters. My father had a similar issue with dampness in the boot of his Auris and water was getting in through the rear light cluster.

Some silicone could help solve it.

I find sometimes if an aftermarket fiiting is fitted they don't fit perfect like they should.

Yup two Auris in this family, sister in laws boot was filling so silicone around rear clusters and then before I picked up the one for the wife I got them to seal ours as they had some condensation and no issues.

Probably the seals around the,rear light clusters. They can be bought from toyota or you can get sealant from any motor factors. 3m do a sealant that doesn't harden so the lamps will be easy to remove if needed in the future.

Tiger seal/tec7 will do too but it will bond the lamps in place which will make them difficult to remove if they have to be removed in the future.

Do not use silicone, it is not suitable for cars.

Guaranteed to be the light seals. They're well reknowned for being poor and causing leaks. It's amazing Toyota didn't sort the problem for the facelift Auris as they knew about it since 2007 when the Auris was released. Piss poor design obviously.

Why not? whats the difference between Tec7 and silicone'

Ive used silicone before on cars for different jobs and it did what I wanted it to perfectly.

Never mind the Auris, leaky tail lights have plagued both the Starlet and the Corolla since the 90's:mad: Luckily its easily fixed.

Silicone is acidic, tec7 is not.

nothing to do with design, it's just a foam seal that is the culprit. It's something that is fitted to a lot of cars.

So you're saying silicone will eat your car paint/body away? What about silicone in car wax/polish?

Im not saying it will but it is corrosive and releases acid during the curing process. Silicone car wax polish is a different kettle of fish and isn't corrosive. You can get acid free silicone sealant too but your normal silicone sealant is not acid free.

The stuff for aquariums/fish tanks is acid free IIRC.

But does using regular silicone sealant actually do any harm?

Well it is corrosive so it has the potential to do so and it has been known to etch certain metals. Why even bother using it when there is more suitable alternatives out there?

I'm asking because I have used regular silicone, tiger seal etc over the years on painted metal on cars and haven't seen any damage. Tec7 is about €13 and cheapo silicone is €2-3

Tigerseal is fine to use on cars, it is not corrosive but it is in and around the same price as tec7. For the rear lamps though id use an alternative that stays soft and doesn't bond the lamp to the car. I used the 3m stuff many years ago which was perfect for this job.

I've only used tiger seal to stick stuff on to bodywork that was falling off!

Same, I've never seen silicone damage paint work when used. It's perfectly fine to use.

Except it's not. You might never have seen it damage paintwork but that doesn't mean that it doesn't happen. The fact is it contains acid so why use it on your car at all?

Had same issue with Avensis, it was the light cluster

johndaman66

Same problem for me with a 2009 Auris. Its bucketing in pretty badly. In fact every Toyota I've had and every one that has being owned in the family which adds up to a considerable few has had leaking boots. I have a full tube of tiger seal but would it be a nightmare altogether if used it and had to remove the tail lights in the future or more just an inconvenience?


Also is this video a good guide? (I assume the procedure doesn't differ massively between Corolla and Auris)

Same with mine. What I did to solve it was to use 2 foam tail light backs instead of one per lamp. Never a leaky boot/lamp since
