  1. My wife would agree with you Ian! She has driven many cars and motorcycles since the mid-seventies. She is a smooth driver and can park a car in any space however minuscule. She has excellent clutch control, enough to roll a car back slightly on our steep drive and catch the car on the clutch with no revving or stalling. I just read your post to her and she said 'I know it's not me, but I'm just fed up of everybody telling me it is!' I don't think every car does this to the same degree and that is why some unaffected people think it's all a big fuss about nothing. I can say that my simple pedal mod has made a big difference to ours although it's still not perfect. I think we won't be keeping this car (which is a shame because it is immaculate and only 14,000 miles) because I like to hear perfect gear changes and certainly no stalling just as I do on my 15 year year old VW and my wife did on her 17 year Mazda previously. It simply is just not a pleasure to drive.
  2. Ah thanks. My comments only apply to cars without SS then. 🙂
  3. No stop/start on mine (thankfully as far as I'm concerned!) Hard to tell from the original poster but I think not on hers too.
  4. We have this problem with our 2014 Yaris 1.33 (14,000 miles). I'm a retired mechanic (46 years) and my wife has been driving for a similar time. To my mind there are two problems, the upper clutch switch and the electronic throttle, both of which work via the ECU so can't be simply adjusted. During some testing with mine I discovered that there was some slack on the clutch master cylinder rod. This is probably caused by the yoke being plastic and the connecting clevis pin is metal. This slack causes the clutch switch to slightly misread the point where you begin pressing the clutch to change gear. I have put a simple workaround for this problem (if your car is affected) in the 'How to do' section. On our car this has made a big difference to the drive. It's not perfect but it is much better. The second thing is the action of the throttle. Modern electronic throttles are made to 'hang' slightly as you lift off (for emissions reasons) and on our Yaris there is also a delay so that the throttle doesn't actually do what you tell it to, rather what it wants to! I think this is part of the stalling and combined with the clutch switch problem makes for an irritating and tiresome drive quite unlike any other Toyota I have driven since 1976. What it really needs is an ECU flash by Toyota dealers so that the throttle and the clutch switch work just as they do on the old model giving you the usual relaxing and easy Toyota easy drive.
  5. I've added the throttle fix as mentioned above. It's important to note that it is more about smoothing gearchanges rather than the actual throttle response (which is another thing that needs fixing) What on earth are Toyota doing to their normal lovely easy drive?
  6. Thought I’d post something I discovered whist looking for the throttle hang on our Yaris which is worse than any other drive-by-wire throttle I have come across. It is a normal feature on most petrol engined cars these days and you can normally drive around it. You can’t eliminate it completely because it is programmed into the ECU. I've noticed that some people barely notice but others (sometimes pretty experienced drivers like me) find it ruins the whole pleasure of driving. I think this because it is worse on some cars than others and I think I have discovered why! If you are not interested in the theory, just scroll down to the last bit! We already know that the ECU keeps the revs up slightly as you lift off, this is not really a problem unless you are lifting off for a gear change. The ECU ‘knows’ as soon as you press the clutch. There are two switches operated by the clutch pedal. The lower one stops the engine starting unless you have the clutch pedal fully down, the upper switch (and the critical one in this instance) is located on the clutch pedal box so that as soon the clutch pedal is touched the ECU ‘knows’ and changes the characteristic of the throttle perhaps allowing a fractionally quicker release of the revs. I took the switch off to see if any kind of adjustment was possible but it’s a fixed thing on the Yaris. It appears to be a straightforward normally-closed plunger type switch. It was at this point that I noticed that the pedal had slightly more slack on it than normal. It looks like the cause of this is that the clutch master cylinder rod and yoke is plastic but the clevis pin that connects this yoke to the clutch pedal is metal. I think some wear can occur between the two leaving enough slack to delay very slightly the release of the clutch switch plunger. I added two small packing washers under the switch and it completely transformed the way the car drove. This is only really a good workaround, the real cure would be a new master cylinder and pin and possibly in a bad case, the pedal itself. I should mention that the clutch switch has a locating peg so you should try the washers on the switch first (as in the pic) to make sure that the they are not to large enough to obstruct the peg and also (depending on how many washers your car needs) that they don’t stop the peg actually engaging in its corresponding hole in the pedal box. If the washers are thicker than the length of the peg, you will have to turn the switch to a reasonable position close to where the peg would have located. Make sure the switch wires are not under any stress. In order to try this simple 15 min modification you will need to first remove the small plastic panel below the pedals. This is just two Phillips screws and a squeeze of a small plastic clip, the panel then unhooks from the front. The clutch switch is held on by a single 14mm nut. You can leave the wires connected. For the amount of wear on my (24,000 miles) car I found, I used two washers amounting to 2.5mm in thickness. It is now easy to drive around the very slight throttle hang which is probably now back to what it was when the car was new. In effect, I have simply moved the switch very slightly so that clutch pedal switch can respond as originally intended when the clutch is pressed. During experimenting with the switch I discovered that it is normally-closed, so the circuit is broken by pressing the clutch. I got some odd results by removing the switch and driving with switch plunger out (as if the clutch pedal was down all the time) and also driving with the plunger pressed in and taped. I won’t bother to go into why this might be but I think the timing of the switch is more crucial than it seems, possibly including a calculation involving the moment of the release of the throttle. Anyway, my fairly crude ‘washer method’ transformed it. All at your own risk of course! So to sum it up: 1. Take the lower panel off. 2. Lightly press the pedal slack up and down whist watching the clutch master cylinder-to-pedal connection. 3. If slack is present, remove the clutch switch and add a washer or perhaps two underneath it. (You will have to experiment with what works best on yours) In order to replace the switch you will need to press the clutch pedal down. You could do with three hands at this point! It is possible to hold the pedal down with one hand and hold the switch and get the nut started with the other but it does take good coordination. If you decide to use a stick or any other device to hold the pedal down be very careful that it can’t slip! 4. Enjoy a completely different drive!
  7. Well, I feel your pain but I don't have the answer to your problem. I have replaced a few squeaky belts on older Yarises over the years . They were mostly much quieter afterwards but not all perfect.. I agree that it's some kind of design fault (or characteristic!) but I don't know why all similar models are not affected in the same way. You could try spraying some silicone belt dressing for temporary respite..
  8. I don't know what size tool Toyotas use. I have only VW. Most garages have a large kit that comprises of most of them. You could do some research and find the correct sized tool individually or take the alternator off and pay a small friendly garage to fit the freewheel for you. Or you could just replace the whole alternator since they (usually) come complete with a freewheel. If the freewheel has been seized for a long time it may have damaged the alternator anyway. There is a video that gives you an idea here.
  9. I can't hear enough from the videos but from the symptoms the alternator freewheel could be the culprit for both cars. Most modern alternators have a freewheel as part of the pulley. (sometimes known as an overrunning alternator pulley) If it fails, it usually causes belt slippage on revving, noises on starting and/or the belt bouncing around. A special tool is needed to replace it and you would need to remove the alternator first but these tools are available reasonably online if you like to do your own work. 🙂
  10. Well I have kind of answered my own question. Yesterday I had a look and found a good cheap/free fix for the throttle hanging on gearchanges. I understand that a small amount of throttle hang is by design but some Toyotas are worse than others really affecting the normal pleasant drive of the earlier cars and making proper crisp, smooth gearchanges every time (even with 47 years experience of driving hundreds of different cars) all but impossible. The difference was obvious immediately. I will add a post if allowed to the 'How to' guides with pics when I get time.
  11. I have the wheel lock key (even took a pic of the lock number just in case). I spent a long time in the motor trade so a spare socket and breaker bar is no problem, 🙂 The original wheel brace supplied in those tool kits are next to useless anyway.
  12. Got a spacesaver from ebay. It's a 2014 unused wheel and tyre. I paid £40 in the end after using the 'Make An Offer' feature for only the second time. 🙂 Bartered down from £54! 😈 Thanks again everyone for your help. Kudos to Parklands Toyota here in Cornwall who have agreed to replace the missing 'goo' (belt and braces now!) I already had a jack lying around.
  13. I think I will just get one from ebay. There are quite a few second hand but unused with tools for £40 ish. I'm not going use it unless absolutely necessary anyway and not for long either! The sealers are useless for many punctures especially if the tyre has run flat for any distance at all or cut on a kerb. Thanks all for your help. 🙂
  14. Hello all, first post here! I have a 2014 13.3 pre-facelift. When I picked it up from the dealer it was missing the tyre sealant in the boot. I have complained about that but I was thinking that I will get a space saver anyway. I have read most of threads I can find here but I want to be really certain before I buy one, My questions are: It has 15" 4-stud alloys on it so can I just assume that a 15" spacesaver listed for my model will fit? And does anyone know if the well is big enough? The car is immaculate and I'm quite pleased with it generally but the throttle response drives us both nuts! Both the lack of feel on the pedal and the hanging. We can drive around it but the hanging is particularly bad, much worse than on any other car I've driven since they started using drive by wire throttles. I'm wondering if I could do something about it, or if mine is worse for some reason?
