The first question has to be - does this still happen when you have the key in the front with you? Either in a pocket, or in the centre-console cupholder which has the key logo on the base of it?

As far as I can tell, it's a combination of sign recognition via the front-facing camera, and map data. The sign recognition seems pretty reliable. The map data, though, is of wildly variable quality - in some areas near me (northeast Wales), the data is wrong more than it's right. And unfortunately, when there's a discrepancy between what the car 'sees' and the data it's pulling from the onboard maps, it seems to give preference to the map data a lot of the time, so the correctly-detected limits from roadside signage are overridden by the incorrect speed limit data from the map.

2L diesel in a 4x4 L&K.... since I've owned it (almost exactly a year), average is 48.92mpg across all the fill-ups in that time. Best tank-full was 57.21mpg (mainly motorway miles), worst was 41.35mpg (almost exclusively stop-start local journeys). Common issues? Well, a trawl through this section of the forum will reveal most of them. Mainly software related...

As you predicted - reply from Parts In Motion saying that they'll refund for the A335H, and to not bother sending it back. Can't argue with that!

A384H blade (Bosch part no. 33970160F2) fitted to rear wiper - sweeps the window perfectly. Parts In Motion are advising incorrectly on their website - they say the A335H is the right blade (it has the right fitting, but is shorter than the replacement) ; and they advise that the A384H is not the correct part (Bosch say otherwise, and it works perfectly when fitted). I've asked them to initiate a return for the A335H, with them paying the postage seeing as it was bought based on incorrect advice given by them...

Nope, diesel 4x4. Don't know which version I'm now on - not near the car to look - but it updated a couple of days ago which is when the new and unwanted ACC behaviour began.

Looks like there's been an OTA software update of some sort in the last couple of days. I noticed the behaviour of my ACC changed, and it started responding to the detected speed limits. Luckily, there's an option to turn that off (go into the Driver Assitance menu, go to ACC, and turn off Speed Limit Response) - the 'off' setting of which persists through a shutdown and restart. The main reason I pretty quickly turned off Travel Assist when I first got the car is that the speed limit data on the in-built mapping is so woefully bad, and so keen to override what the car is actually 'seeing' on roadside signage, that it's almost dangerous. Around my part of the UK, at least, the mapped speed limit data is dreadful - to the extent that, if Travel Assist had its way, there are locations where the car would think a limit had dropped from 60 to 40, or 50 to 30 (or even 20) and would slam the anchors on in response even though the actual limit was nowhere near what the map data thinks it is. Borderline dangerous, if someone's driving too close behind.

Just had a response to the e-mail I sent to Bosch (asking why they appeared to make a blade which is too long, and a blade which is too short, but not one which is just right - maybe they read Goldilocks too often as kids!). Their response - "We also make a A384H blade, which is a few mil longer than the original fit but pretty much the right length". So I've ordered one of those from PartsInMotion too, to see what the fit is like. If it's a better replacement than the A335H, they'll be getting a request for a return of that one, with postage at their own cost on the basis that the advice given by the 'fit checker' on their website is wrong.

I've just ordered one of the Bosch A335H blades too. Like yours, the one fitted to mine is 355mm along the rubber - the Bosch options with the right fitting are either 330mm or 400mm. Looking at how close the sweep of the blade currently gets to the top of the glass, I suspect the longer one might be too long - so sacrificing a few mil either end seemed like the best way to go. It's bizarre that either Skoda have fitted something which isn't a standard off-the-shelf blade length - or if it is, why it's seemingly almost impossible to find a direct replacement without paying silly money for a genuine Skoda part.

Thanks, Foster91 - but that looks to be a kit of all three blades, I just need the rear. Also the clip shown on the rear blade in the photo is completely different to the one fitted to the mk.4 - it looks like the clip which fitted the rear wiper on the mk.3 before Skoda changed the design of the wiper arm in, I believe, 2022.

Yeah, as I said, I've Googled it. That's the problem. Contradictory results suggest either the Bosch A335H (blade length 330mm) or A405H (blade length 400mm), depending on who you're inclined to believe. The blade currently fitted measures 355mm, so doesn't really match either. So I was kind of hoping for an answer from someone who's actually bought a blade and can tell me what they bought and whether or not it fitted.

Can anyone confirm that 3V9955425A is the correct part number for a rear wiper blade for a 2024 mkIV Superb rear wiper please? I'm fairly sure it is, but Google seems to suggest that there might be two different part numbers depending on build year...

Any reason why you're not just coming out of the USB-C on the centre roof console?

For this very reason, I've turned off the "virtual pedal" foot sensor which opens/closes the boot. Don't miss that particular function in the slightest, and can now lean into the boot without it trying to eat me.

As above. The sound you're hearing is likely the overspeed warning (exceeding what the car thinks is the speed limit). It can be turned off easily (right-hand thumb-wheel on steering wheel) - it's become a habit for me now, first thing I do after starting the car, takes a second or two to do. As far as I know, there's no audible warning for a change of speed limit. And yes, the car's onboard mapping of speed limits is woefully bad - so many errors around where I am (north Wales). Even recognition of a clearly-posted speed limit sign can be overridden a few yards further along the road by the map data's incorrect speed limit - followed by a correction as you pass a repeater, followed almost immediately by the car again reverting to the incorrect mapped data 😂

Nextbase are indeed bull****ing you - just as they've been bull****ing me for the last 10 months about the fatal bug in their MacOS viewer software. My Nextbase is mounted on the windscreen of my Superb, next to the rear view mirror, and locks onto GPS with no problem.

Regardless of any issues you might be seeing with the ambient lighting package (and that sounds odd - I thought it was an 'all or nothing' kind of thing, not a situation where you could have some elements of it but not others)... if I was in your shoes I would absolutely not be happy that a) I was driving a car which had suffered significant collision damage in the recent past, and b) that car had been sold to me by a dealer who hadn't disclosed the fact to me. Personally, I'd be rejecting the car, looking for a replacement of the same or higher spec/quality at no additional cost.

If it was me, and I'd been sold a car by a Skoda main dealer without being told that it had been involved in a serious collision and had undergone major repairs, I'd absolutely be rejecting the vehicle and raising a complaint with the local council's Trading Standards department (and probably also getting a solicitor involved). You don't say where you are - but in the UK, if you ask a dealer whether a car has ever sustained any accident damage, they have to declare it. Not doing so (and by the sound of what you say they subsequently told you, the absolutely knew about it) would put them on extremely dodgy ground legally-speaking.

I have a NextBase in mine. They used to be my go-to brand for dash cams - I've had three in my vehicles, and I got them for my daughter, partner and mother too. However, I'm not sure that I could, in all good conscience, recommend them now. Last spring they made some changes to their Dashcam Viewer software which introduced a fatal bug into the Mac version - rendering it un-runnable on MacOS (certainly for me, and I'm aware of lots of other people who have the same issue). Their customer service has been shocking - they told me last April that "a fix is imminent", and that turned out to be the first of many lies. Bottom line is that, 9 months on and many "an update to fix the problem is just around the corner" untruths, there still isn't a fix. At least they've stopped saying it's "imminent" now, and are being more truthful by telling me they have no idea when it'll be resolved! So, basically, not-too-bad cameras, awful aftersales service.

I guess I got lucky - mine was only in for two days, all went well with no issues. There seem to be quite a few instances of this update taking a lot longer than anticipated due to unforeseen problems, though.

... Neither of which are 'my' tyre place. I've got my local independent tyre-fitting shop who I've been using for years.

I don't think they'll care either way, to be honest - they're competent enough to be able to deal with any sort of TPMS system they might encounter. If anything, I think they were probably more put-out when I got the 4-series - the previous 3-series did like to go through tyres! Its replacement was much better. The Superb is, as far as I know, still on its original tyres out of the factory. Currently at about 12k miles, and they've got a good bit of life left in them yet...

In 7 months with the Superb so far, mine's only done this twice - both times while reversing at low speed (walking pace or less). Once it was the car being over-cautious about the proximity of a low brick wall. The second time it was some long grass behind one of the sensors 😆

I think that's more to do with the driver's choice of tyre fitter than the TPMS system! I came to Skoda after two BMWs which, combined, saw me through about 16 years of motoring. They both had TPMS. Multiple tyre changes, and my local trusted tyre place never had a problem with the TPMS valves. I guess it depends on whether the fitter knows what they're doing.

Have to admit, I was a tiny bit disappointed that the Superb (mines a 2024 L&K) doesn't have active TPMS - just seems to be a passive system which, once set, monitors wheel rotation through the ABS sensor and throws a warning if there's any imbalance across one of the wheels. Coming from a 2016 4-series with active TPMS, I sometimes miss the ability to check actual pressures on the screen. Seems like a strange thing to sacrifice when looking for things to value-engineer out of a new model.
