I know the fob switches off after a while, but not if walking across car park, so at risk if bag not working.
If the system is working correctly, you should be protected when walking across a car park. That is because, as I understand it, the Kessy system, and those from some other manufacturers, incorporate a time-of-flight signal as part of the communication between key and car, just as GPS does: time of flight determines distance accurately. So the reason touchless unlocking stops working when one is more than a few feet from the car is not because the signal is getting weak but because the car knows for sure the distance between it and the key (the real key, not the thief's device). That renders man-in-the-middle attacks useless -- unless someone invents a way to circumvent it.

I don't understand?
Doesn't the procedure where you lock the car with the button on the key and then within 5 seconds touch the 'lock' sensor on the handle not work with the motion sensitive keys? This disables Kessy and means the car can only be unlocked using the button on the key.
Yes, that procedure disables Kessy. But:
(a) you have to remember to do it;
(b) you have to assume the system is working correctly, i.e. that the button-press on the key followed by the touch on the handle really has disabled Kessy;
(c) you have to assume thieves have not (yet) developed a way to overcome that.Some will conclude that is quite secure enough. Others will be sceptical and prefer to add their own layer of security with a metal shield to block the radio signal.
It might be better to make sure keys are not kept on a hall table overnight, or anywhere else they can be easily found after a front door is breached.

A small tin with a well-fitting lid works perfectly for me and fits in my pocket if need be.

Is there a way for me to get the update to start?
You can look at Settings - System Information - Update Software to see whether any update is ready for you. But if it isn't, all you can do is wait. And when it is your turn, you'll be notified anyway.
To be fair, this is no worse as an approach than it is with most mobile phone OS updates. What makes it annoying is that Skoda seems to have cheaped out on renting bandwidth so that some people have to wait a very long time for their turn to update.

The fix for Android Auto that works for most people is when the infotainment system software updates itself to version 0330.
As updates happen over the air, the dealers don't get involved if they can help it, and many of them don't understand the issue.
My wife's car spent an entire week saying 'Software update in progress' and there was nothing I could do to control that. When the update finally completed, Android Auto worked properly for the very first time.
The whole update system is really badly implemented, but you can hope things will resolve at some point. In fact, hope is all you can do,
By the way, Skoda absolves itself of all responsibility by saying in all the brochures and other publicity for many months that Apple Carplay works wirelessly but Android Auto works wired. If you were to complain to Skoda UK I think you'd be told you are asking for a feature that was not offered. Neverthless they have been working, belatedly, to fix it.
Connecting via cable should get you going while you wait,

The problem and its solutions have been discussed on a 2-page thread here:

You are well aware of the pros and cons of each car. When I come across that situation, I resolve it by waiting for another car to come up that has fewer compromises. And I travel to get it if necessary, a long way sometimes.

Good luck with that. The usual complaint is that Android Auto constantly disconnects, but some people have trouble with Carplay too.
First thing is to make sure the infotainment system software has updated to 0330. That may or may not help, but there's no point in trying any other fixes until that is done.
Mind you, mine has been saying 'Software update in progress' for an entire week now. Speaking as one who developed and published successful software for 20 years, I can say the software on these systems is disgraceful, from small things such as a failure to indicate exactly what is happening and buttons that do nothing when you press them, to big ones such as stuck updates.

It was 0330 for the system software. But it was different to previous updates I have had as there was a message about applications update that I have not seen before. No other update numbers for android auto that I could see
Thanks

Finally, I had a large update come through on my infotainment system on my Karoq SL 1.5 2023 this weekend. It has fixed the bluetooth / android auto issues. Solid connection now without having to use a cable.
Would you be kind enough to post the version number following the software update? 0330, perhaps? Thanks.

I too have a 2023 Karoq 1.5 TSI Sportline. I live on the edge of a city. Yesterday evening I drove the 6 miles into the city centre and the 6 back again. This was from a cold start in cold weather, with light traffic, a few stops, and some parking manoeuvres. Consumption on the round trip was 42 mpg.
If I was getting late teens and low 20s I'd be as puzzled as you are.

People in the trade. Are these fitters at Tyre & Exhaust centres?
An old friend of mine owns a tyre supply and fitting company and has contacts in the same trade all over the UK. He deals with the wholesalers and has contacts with manufacturers. We speak most weeks. He has a more wide-ranging overview of the business than any fitter.
I too liked Michelins made in Dundee and liked going round the factory, but they were mostly the smaller, cheaper sizes and PCP deals killed them as nobody is going to fit top-quality tyres when they are due to hand a car back.

Sorry, only just caught up with this thread..... my wife's B-max has been fitted with Goodyear Vector 4seasons gen 2 all round and, 2 years ago when her front tyre was flattened by a pot-hole, I remember thinking at the time how thin the side-wall looked. This is not a scientifically measured observation, just my impression at the time.
Maybe when I come to replace the tyres on my Karoq, I'll go for the Bridgestone Turanza all-season 6s
Yes, people in the trade, who see far more tyres than any of us here, are seeing too many Goodyears being scrapped because of big bulges in the sidewalls. In other respects many of their tyres remain excellent.
Goodyear develops its tyres for the European market at Hanau near Frankfurt and Colmar-Berg in Luxembourg. They don't have many of our crater-like potholes and vicious speed bumps in those parts.

The 4*4 version has 225/45/19 tyres as standard so can't see any issue with fitting those.
The 4x4 version has 225/45/19 tyres as one of the standard fitments. 245/40, as I was proposing, is another. Both the Crater and the Vega 19-inch wheels on the Karoq come from the factory with any of the following: 225/40, 235/40, 225/45 and 245/40 tyres.

I'm not sure that I would risk fitting a non recommended/ non homologated size tyre.
Nobody so far on this thread has suggested that.

The Goodyear Vector 4Seasons is still a good tyre and I used them on a Yeti a few years ago. However, when buying all-season tyres for our Karoq Sportline 1.5 last month, I decided against them for 3 reasons:
1. They are said by some people in the tyre trade to have thinner sidewalls than the competitors, making them more susceptible to pothole and kerb damage.
2. When I was shopping last month, the 4Seasons Gen 3 (the current tyre) was on sale in very few places; most places were still selling the 4Seasons Gen2. Moreover, according to this page, the 4Seasons Gen 3 is not being made in the 225/45 R19 size: https://www.thetirelab.com/goodyear-vector-4seasons-gen-3/
3. Compared to more recent designs, the perfomance of the Goodyear 4Seasons is now a bit middling. See https://www.tyrereviews.com/Article/2023-Auto-Bild-All-Season-Tyre-Test.htm
Instead I bought the Bridgestone Turanza All Season 6, the newest of the all-season designs, having gone on sale in 2023. It is nothing like the rather hard summer tyres that one is used to seeing from Bridgestone. Our Karoq with 19-inch Vega wheels came on a set of those summer Bridgestones (225/40 R19 Turanza T005) and I couldn't wait to get them off. On the Turanza All Season 6, the ride is transformed as well as the grip. For one example, sometimes I can't feel cats' eyes, only hear them.
Some will say why not go for the obvious choice, the Michelin CrossClimate 2? The original CrossClimate revolutionised the all-season tyre market and is the best-selling all-season tyre in Europe. It still wins many comparative tests -- on several criteria but not all. In particular it beats all competitors on snow perfomance. Michelin optimised snow performance to a remarkable extent in moving from the original CrossClimate to the CrossClimate Plus and then the CrossClimate 2. They know their market. The tyre is aimed at all those parts of Europe that get more snow than we do and appeals to people who can use it to get snow performance almost equal to a winter tyre without the bother of swopping from summer to full winter tyres. But - and it's a big but - Michelin optimised the tyre's snow performance by reducing performance on cold wet roads, both in braking and in lateral grip. Does that suit the UK market? How many days of snow per year do you get where you live? Maybe none, maybe two or three? Now how many days are there with cold wet roads? Fifty? A hundred? The Turanza All Season 6 beats the CrossClimate 2 easily for wet braking and wet handling. That makes it a better choice for much of the UK, I suggest.
However, I did not replace the 225/40 R19s with 225/45 as you are contemplating. Instead I went for 245/40 R19. That size is a Skoda-approved tyre as one of the factory fitments to Crater wheels for the 4x4 Karoq.
Some dimensions:
225/40 R19 -- 89 mm sidewall height, 481 revs/km
225/45 R19 -- 102 mm sidewall height, 465 revs/km, a 3.46% increase in circumference
245/40 R19 -- 99 mm sidewall height, 469 revs/km, a 2.55% increase in circumference.A tyre does not get its final width until mounted on a rim. Widths when mounted on 8J rims will (I think - open to correction!) be 230 mm for the 225 tyre, 242 mm for the 245 tyre. So the 245 in use is 12 mm wider than the 225, not 20 mm as one might think.
Thus if you choose 245/40 instead of 225/45 as you were contemplating, you will get 12 mm more width at the rim (6 mm each side) for better kerbing protection, only 3 mm less sidewall height than the 225/45 but still 10 mm more than the 225/40, so adding a useful amount to the ride improvement given by the softer all-season tyre, and a bit less of an unwelcome speedo error. 245 tyres will use a little more fuel than 225 but that will be offset by the small increase in gearing, not that you'd notice either change.
In conclusion, the Turanza All Season 6 tyres in 245/40 R19 suit our 1.5 Karoq perfectly and have transformed its comfort and its grip on winter roads. I also regard their size as looking better suited to the car. You could of course get an even softer ride by fitting smaller wheels, but I didn't have the money to spend on that as well as tyres. With the right tyres the 19" wheels are quite OK.
I must thank those who have posted here in the past on the tyre threads for helping me reach a good decision, particularly Carlston.

This is more about the facelift in general than the Sportline in particular, but may nevertheless be of interest:
I may have time to say more later.

As per my reply above you can have the speed sign displayed on the map screen. It is done purely by sat nav position and not by the optional traffic sign camera and works well.
Kenny R is of course right. Tick the box to show traffic signs. The maps do not always have the correct speed lmit data, so it is not 100% reliable, but the car changes its display promptly after a change of speed limit.

Traffic sign recognition is part of the optional 'Travel Assist Package' (£1,145) and the 'Travel Assist Package Plus' (£1,590). Automatic headlight control is part of the 'Light Package' (£2,075).
There are some phone apps that can display the current speed limit.

Indeed. Cunning tweaks that people apply when they're trying to achieve fractional extensions to the performance envelope for a few laps on a racing circuit have vanishingly little relevance to good practice for day-to-day driving on public roads.
And yet ten per cent more or ten per cent less inflation pressure has a very large effect on the way any car handles, even day-to-day on public roads. If you are not interested in understanding all the various factors that contribute to that big change, fine, just move on. Tyres are just boring black round things, aren't they?
-
I suggest that the reason for using a bit more pressure in winter is that a bit more pressure makes for a significant increase in tyre temperature, and a higher tyre temperature makes for a significant increase in grip. Even though winter tyres are meant to work in low temperatures, these principles still apply, since there is no getting away from the pressure-temperature law of gas physics.
Here is a discussion of the matter as it affects racing tyres. But again, the principles are the same for road tyres, even though effects may be less dramatic. http://www.tal-ko.com/getting-the-best-from-your-tyres

I'd guess the legal requirement never went beyond 'wings' and later 'spray suppression devices', i.e. mud flaps never became compulsory, but as you say the Construction and Use regs would provide the definitive answer.

Car Mechanics, November 2016 issue, had an article on whether to use grease or not. There was an authoritative contribution by someone who as far as I can see was a quality assurance engineer with the Ministry of Defence. It's a two-page spread, so too long to quote here. In short, he does not grease bolt threads but does grease their taper section. He greases the centre spigot. As for the hub face, he greases it lightly but then wipes it off with a cloth, leaving some grease in the valleys but not on the peaks of the metal surfaces. And he uses lithium grease, never copper. He gives reasons for all of this.
