  1. As well as the above, is there any chance that your tyre pressure gauge isn't that accurate? Just out of interest, what brand of tyres are you using? I'll throw this one in as an extreme outside chance, but anyway, has the car had uprated springs fitted to the back in the past, to cope with a permanently full boot of rep's gear, whatever that was? ( I must add that I don't know if uprated springs are even available, but these cars often look heavily laden on the back end, even when they're not full of passengers). The original shockers are Kayaba brand (KYB), made in Spain, if
  2. Yes, I think that is entirely possible - from what you've just added, most probable! Is it safer (if there was a mechanical failure somewhere) that you force the transmission brake on, or off, with the cable operation in tension, from a designer's viewpoint? That is what I was trying to guess. The gear lever on the Corolla looks much more conventional than the older style, perhaps to make the hybrid drivetrain more 'mainstream' from a controls point of view. The older control, this one is from a late model Auris, is like this:- So the transmission brake is separate
  3. This is a very valid point that Catlover makes, perhaps you could see if the effect is only evident where the lorries create these grooves - in the left hand lane? The feeling of having your wheels climb up the sides of these channels can be quite disconcerting. And a brisk crosswind might make this effect much more obvious. Also, how and who checked the wheel alignment? I think that the Yaris, as almost all cars, will have the wheels set with some very slight toe-in (wheels pointing towards the centre of the car very slightly). If the car has a some toe-out (wheels pointing away from
  4. The transmission brake parking pawl is driven by an electric motor on the Auris and Prius, the newer models don't have this, they have a Bowden cable arrangement I'm just speculating here, the electric motor type could be designed to push and pull the pawl into and out of engagement, that would be very simple to design. With the Bowden cable operation (like a bicycle brake cable, or handbrake cable) the gear selector cable will forcibly engage the pawl, but I presume its withdrawal is done by a spring, (it is not usual to have a Bowden cable used in a 'push and pull' fashion, but not
  5. The 2 litre hybrid engine has a GPF (gasoline particulate filter) fitted in the exhaust. I would imagine that this is another part of the exhaust that will draw heat from the exhaust gases, leaving the rest of the exhaust running cooler, and thence more prone to condensation, perhaps? I don't believe that these devices are likely to suffer the bad reputation that their diesel equivalents have got. As I understand it, they are necessary to clean out particulates that are a byproduct of the 2 litre engine's direct injection system. As engine emission regulations get tighter then they wil
  6. This is most likely the cars transmission brake (the one that isn't the handbrake) releasing. You have probably released the handbrake before the 'system' turned on properly, or it wasn't on hard enough, and the car is then being held by the transmission brake only, in which case it can release with an abrupt operation, as its tension is unloaded. Or, it's the rear brake pads, after having got wet beforehand, that have lightly rusted to the disks, and are then becoming unstuck when you move off. Neither of these situations need be of concern to you at all. Note that the 12v battery doe
  7. If you can't do with waiting for a Corolla to turn up, the Prius gen 4 (2016 ->) has the same engine and transmission as the 1.8 Corolla, so you could judge if this is to your liking, as an idea of how the Toyota hybrid system operates in practice. It's worth asking the salesman where to find the dash mpg reading. Make a note of what it was reading, and then re-zero it for your test, to see what you get out of it. The rear seat accommodation of the hatch isn't very generous (the estate is bigger - it has a longer wheelbase), so sit in there as well. The interiors are a bit d
  8. "Caross" = car body, no? As in carrosserie. :-)
  9. I think the criteria that have to be met for it to work are the same as other manufacturers'. In the government tests of the time (I'm uncertain the latest ones), the cars must be stored at a regulated temperature of 25 celsius for 24 hours before the test commences, so not like anyone's 'real' usage at all
  10. This thread answers some of your concerns, I think.
  11. Exactly, I can quite understand if it's not there. On our 2013 Auris (Corolla), there is no dash access to this setting, (but I have adjusted it with Techstream from '3' to '5' as it happens). I don't think the previous model Auris (->2012) had it, though. It doesn't list that option on the Carista 'sample customization' page: (note the near-invisible slider on the r/h, btw.) https://caristaapp.com/vehicles/toyota/avensis/3rd-gen
  12. Whilst there is only a vanishingly small chance of this being the case in your car, there is an option of selecting that feature on many Toyotas that are sold up this end of the world. Access to the menu is through Techstream, and doubtless many other 'tools', and also dashboard menus on the latest cars. I think it's called the 'comfort indicator' setting (or maybe that's VAG?). From memory, the settings are: on/off, 3, 5 or 7 flashes. Perhaps yours is set 'off' ?

    If it's of any use, there are some slightly bigger pictures in this thread from 4 years back. I didn't notice an obvious joining of two pieces on mine (taken off ~ 2015 Auris). I can't see why the manufacturer would allow them to come apart that way, although it would suit your situation! I think just the valve core can come out, and that's it. I'll check the one in my garage shortly.

    I understand it to be around 5 years. I have an idea that if there is no wheel movement detected then they may consume less power, so they would last longer with less mileage. The button cell powering this is potted in an epoxy compound - I have an old one in my garage! The potting compound is not meant to ever come off. I have no experience of them, but I believe there are aftermarket ones readily available, for less money.
  15. Just a few thoughts to add: Whilst this might offend some people, I think all cars are a bit of an environmental disaster. In an Auris hybrid, as I understand it, the batteries are about 45kg, so there aren't as many as there are in an electric car. The electric motors etc. account for about another 45kg, if I remember correctly. The car seems puts to put them to good use for the extra environmental footprint they present. Whilst this may not reflect the use the OP is planning for, the preference for hybrids amongst taxi drivers must count for something. There is some comfort
