"Obviously, if we had been aware of Sabis's shortcuts in the testing programme, the TSB board and I would never have pressed ahead with switching to the new system at that time."
To turn this on it head, one wonders how much pressure was coming from the board for Sabis to be afraid to tell the truth?
One might naturally assume from the article title that at some point I'm going to be able to hit the teletext button on my tv and see ... teletext.
But what this is, is someone who has found a way to broadcast their own text service to their own tv. Kind of interesting of course, but not really the service coming back from the dead.
Slightly OT, but a group in the UK actually recently built a steam locomotive and operate it fairly regularly[0], so steam is kinda back from the dead…
Not in some parts of Europe at least. It was just carried over to the digital signal. I honestly don't know how, but there must be room for it in the DVB-T/C/S signals.
In DVB (and IPTV systems that use MPEG TS) Teletext is sent in its own pid, along with the audio and video pids of the program being watched ( for the details you can check ETSI 300 472).
vlc btw contains a decoder for teletext pages, you can tune in to a dvb stream and look at them.
Trivia: in some countries (for instance in Switzerland) subtitles for movies are sent sometimes as semitransparent teletext pages (in CH it is on page 777) even if DVB supports natively subtitles.
The software before the update was used to detect if a car was being tested for emissions/ fuel consumption. Then it lowered power and fuel consumption.
So it gave skewed figures.
Which means in normal driving it was always giving more than advertised figures.
So the fuel consumption has not changed from before update for normal driving. So you won't see any difference.
Edit: ah my bad.
Ah, it specifically relates to particulate emissions, that is not related to fuel consumption
> So the fuel consumption has not changed from before update for normal driving. So you won't see any difference.
Uh, I think you've got it backwards. Won't the updates mean it drives in 'test mode' (e.g. acceptable emissions that meet the standards) all the time? Meaning that it will result in some downside (which was apparently bad enough that they cheated in the first place)
Specifically, reducing NOx (without using DEF) pretty much requires the engine to burn a richer mixture. This means more fuel injected, so less fuel efficiency and more unburnt hydrocarbons clogging up the particulate filter. Without retrofitting DEF systems onto the older cars, any fix is likely to be a significant hit to efficiency and reliability. I think maybe performance would suffer too but I forget how that would work.
It will still pass, they were just pushing the emissions tests lower so that the car could fit in a lower tax bracket. I don't know about every country, but in the UK you get taxed on how polluting your car is.
I believe that various governments have made a promise not to increase the taxes on existing cars, as the consumers were unaware at the time of purchase.
Getting owners to go in for the fix is part of the problem. Some states will most likely require it to be done before renewing the license plate, or before allowing resale, etc.
