2016 Auris fuel cap

Hi,

I recently picked up a 2016 1.2T Auris touring. 

Unfortunately the toyota main dealer hasn't actually been of much help so far (issues with creaking suspension within 100 miles of driving) and no interest despite the toyota approved used warranty etc. However now the fuel cap doesn't appear to want to tighten up. But I'm not so sure.

I thread it into the fuel filler and as I tighten it, it just stops and barely clicks. My previous car was admittedly a 1999 toyota corolla which the fuel cap would click a few times when tightening, but atleast it felt like it was actually tight. This one doesn't it takes little effort to unscrew it

Is this normal?

 

Thanks,

Taylor

Ok, 

so basically all you need to fix your problems is a can of wd-40 silicone spray. You need to spray your suspension arm bushes both sides and cricking will disappear immediately. For ten fuel cap undo and keep away from the filler spray some silicone spray on the inner side on the thread end where the cap mushroom is and try to rotate by hand , wiggle a bit then replace to the filler and try to see if it clicks better. If no success repeat the process. Spray that area all around as shown on the picture.

With the Used Certified warranty, you must ask them to replace the control arms.  But check your term and condition first because most warranty do not cover rubber parts and bushing.  Relax-Warranty also does not cover rubber bushing and worn rubber.  Just clean it with pressure washer on car wash, spray the rubber bushing with silicon or teflon (bike chain) spray that has no petroleum base.  Do not use WD40 because it degrades rubber parts.  Always use only Silicon or Teflon PTFE spray.   Just like Gates CDX belt in my bike or Treadmil, we can always use silicon spray that has no petroleum

I agree with what you've said.

But, contrary to what I expected, WD-40 brand Silicone Spray does list mineral oil as an ingredient!

I did try to ring them a few times over the last couple of weeks about this and some other stuff; their enquiries/helpline number goes to a voicemail, which tells you that it is full and no further messages can be accepted.  Cool!

I've only got a very old can of the WD40 Silicone, so old that it has no ingredients on it.  I've been using other brands over the years which don't list mineral oil as an ingredient, as it happens. The WD40 Silicone spray I've got does seem to have a scent added to it to make it smell fragrant (!?).  The one in the photo has 'aromatics' as an ingredient.

Just an FYI really!

This is an up-to-date picture of one in Homebase:-

WD40 is just a brand, it has different kinds of lubricants/sprays.  What I found works the best for rubber is generic Silicon or PTFE spray for £2 from Lidl or Aldi.  They are great generic brand and super cheap.  it contains some mineral oil/petroeum base but it is short carbons and evaporate very quickly.  The original WD40 (formula 40) for penetrant seize screws and bolts have long chain of petrolium and not recommended for rubber parts.  So, it is still ok to use the one in your picture (Silicon WD40), it is as good as the one fom Aldi/Lidl brands with better built straw.

Yes, I've used those before.

Curiously, the 'not specialist' WD-40 silicone spray (cheaper, and in the larger tin), doesn't list mineral oil in its make-up.

I finally decided to email my questions to the designated email address at WD40.

They sent an email reply the same day.  It said to telephone their helpdesk instead, that's the one that doesn't get answered (see above), this time on an 0844 number.  Superb.

Just something to watch out for with regards lubricating the petrol filler cap with silicone, back in 2007, there was this, where silicon is mentioned :

https://en.wikipedia.org/wiki/2007_United_Kingdom_petrol_contamination

An extreme example perhaps, but oxygen sensors don't get on well with silicone that much.  It's the same with silicone RTV gasket compound, (if ever you needed it) - one compatible with O2 sensors is available instead, I see.

Thanks for sharing Gerg. 👍

For the petrol cap there is no risk of using silicone spray as this will only clean and lube the moving parts and any excess will evaporate before refitting the cap back. Can clean with carb cleaner or contact cleaner, anything that is thin and goes out under pressure plus evaporate quickly. Can do also with soapy water bath if removed completely and needs to be dry well before fitted back. I don’t remember how I cleaned mine previously but for sure I had same problem.

Yes, Silicon spray stay much longer on rubber components than penetrating oil (original WD40) and harder to remove.  However, brake cleaner and electronic clener can strip silicon pretty easily.  

WD40 silicon spray is the same as other silicon spray.
