Honda Jazz Mk1 2002-2008 / Re: The engine doesn't hold idle if engine is cold

Your current problem points to the ECU not really realising that the engine is cold and that it needs to increase the opening times of the injectors to squirt more fuel in to get a rich mixture while the engine is cold. It's almost like it always thinks the engine is warm enough to "come off choke".
First thing I would do is get an OBD2 reader and monitor the engine water when the car is started. Even a very cheap reader will do this.
The value that you'll see on the reader is the value that the ECU is reading from the sensor and will confirm whether there's an issue with the temperature sensor.

Honda Jazz Mk4 2020 - / Re: Question about the shifter trigger/release button on the Crosstar
« Last post by Lord Voltermore on July 11, 2026, 09:22:55 AM »My strategy has been to not think too deeply about it. 
Now it just happens instinctively with no special thought about whether or not I am pressing the button.
I have had to go out to the car to experiment
To come out of P you must press BOTH the foot brake and the trigger. If you dont press the footbrake the trigger button is locked. Presumably as a safety measure.
Once out of P you can move the lever between R N and D without pressing the trigger .But you have to press it to go from D to B. . IIRC you can shift both ways between R, N and D (and from B into D ) without pressing the trigger whilst the car is stationary. But the trigger may be locked to prevent you accidentally going from D to R or R to D while the car is moving. (I didnt check for that) IIRC you can slip out of B,D or R into N without pressing the trigger , perhaps as a safety measure.
So many variations . Also the car is able to detect even a slight rotation of the wheels. If for instance you reverse then select D it might still detect slight movement and exceptionally lock or require the use of the trigger when normally it would not.

If you ask me, extending the warranty from 3 to 8 years—given Honda's current situation in Europe—looks like a desperate attempt to escape a precarious and virtually irreversible predicament.
For instance, there are only 9 (nine!) dealers left in the Netherlands, whereas here in Poland there are still 16 remaining, plus a number of "service points."
And just look at that new Chinese brand BYD: already 22 dealers in the Netherlands; in Poland, 29 operational dealers by June 1, 2026, with a target of 60 (sixty!) by the end of 2026.
It is a real shame
to see things going this way for Honda in Europe. We are genuinely happy with our Jazz and were pleased with the dealer too (until we discovered they had simply vanished...).Unfortunately, our next car won't be a Honda....

« Last post by zdan on July 10, 2026, 07:46:42 PM »Digging a bit more into the car sales from this year. I looked at the official data from SMMT that provides the monthly number of cars sold in the UK.
Year to date. Up to June (so first half of the year).
Honda has 10k sold compared to 13k (this time last year) => about 22-24% fewer cars than the already bad last year.
Some interesting data:
Company / cars sold / compared to last year
BYD / 38k / +95% more than last year (pretty much double)
Chery / 18k / +9999% (they sold 0 cars in the first half of last year)
Geely / 6.5k / +9999% (they sold 0 cars in the first half of last year)
Jaecoo / 34k / +305%
Omoda / 18k / +170%
Source: https://www.smmt.co.uk/vehicle-data/car-registrations/
Sales look a bit grim, but I still have hopes that they could somehow come back. Hopefully, the new warranty boosts their sales.

Honda Jazz Mk1 2002-2008 / The engine doesn't hold idle if engine is cold
« Last post by daros on July 10, 2026, 07:28:50 PM »Hi to all. I have a problem with my Honda Jazz 1.4 2011, which I bought two years ago. The symptom is getting progressively worse as the months go by.
Symptom: The car always starts first time, but then it won't hold idle and stalls if you don't keep the engine at a minimum of 2500 rpm. After two minutes, shortly after the blue cold engine light goes off, it holds idle again.
Furthermore, before warming up, the engine has no power and I can't make it up the hill in front of my house. As soon as the engine is warm, everything works perfectly.
I have changed the spark plugs and replaced the throttle body, but the behavior is the same.
It reminds me of the behavior of some cars from 40 years ago, which needed to have the "choke" pulled out and be warmed up before you could ask the engine for any effort.
Thank you for any help.

Honda Jazz Mk4 2020 - / Question about the shifter trigger/release button on the Crosstar
« Last post by ione on July 10, 2026, 06:24:45 PM »Hi everyone!
I've been wondering about a specific detail regarding the gear selector on my Crosstar, and I wanted to check how you guys use it in your daily driving.
I was recently reading the car manual's section on "Shifter Operation." On paper, it says that to move the lever between certain positions (like N to R), you are required to press the release button—the "trigger" on the front of the knob—while for others (like D to B or N to D), it's not necessary.
To be honest, I find it quite confusing and hard to memorize exactly when I need to press it and when I don't while driving so I've just started pressing the trigger every single time I move the lever, regardless of the gear.
However, I've also noticed that even if I don’t press the trigger, I can still move the lever through the gate pretty much the same way (I have noticed it doing it by mistake)
This leaves me with a couple of questions:
Does it actually lock for you? If you try to shift from N to R while stationary, or from D to R, does the lever hit a hard physical stop if you don't touch the trigger? Or does it give way and let you shift anyway if you push it with a little bit of force? I wonder if the spring in my shifter is just a bit soft.
What is your habit? Do you also find it much easier to just press the trigger by default every time to avoid overthinking it, or have you actually memorized the specific rule for each transition?
Looking forward to hearing how your selectors behave and how you use them. Thanks!

Why is that? History repeats itself: after the Japanese and the Koreans, it’s now the Chinese.
And if they can deliver good cars at reasonable prices, they’ll be successful—especially if they come out with inventive small cars like the new BYD Dolphin G. A good looking and spacious supermini plug-in hybrid with an all-electric range of 65 miles—and significantly more than that in city traffic.
Long (holiday) trips without charging anxiety or (long) charging stops; it simply runs like a fuel-efficient "standard" hybrid on E10.
And all that for a very reasonable price? We haven't seen anything like that from Europe, Japan, or Korea!
Just as an example: our driving profile consists mainly of (short) city and urban trips, all of which can be covered in pure electric mode. We have charging facilities (a simple grounded socket is all that is needed) in our garage. At a cost of € 0.16 (not quite 14 pence) per kW.
Is it any surprise we’re planning to take that car for a test drive soon as a potential replacement for our five-year-old Jazz?
And IF we would go for a BYD Dolphin G, it’ll definitely be orange...

The German car giant, which has been battling a downturn in performance, announced the measure after the board failed to agree on job cuts of up to 100,000 roles in a crunch meeting.
VW said that halving the number of models it sold would allow it to focus on its best-selling and most profitable vehicles.
It did not say which brands would be affected or when the changes would be made, but the move raises the prospect of dozens of popular models being scrapped.
