Octy-PHEV

On my 2023 Octavia, you can disconnect the link between the ACC and the traffic sign recognition, so I presume you can too. The setting is called "speed limit preview" or something similar. It drove me nuts too until I found how to avoid the ACC target speed changing automatically.

I'm curious to know how big a gap there was between the cars when yours came to its sudden stop, @croquemonsieur Was it a very near thing, or was there sufficient gap to give you confidence it would always be safe?

Yes, the setting for showing the speed limit has gone for me too (on v 1989). It must be always on now. It also shows a warning triangle if I've just passed such a sign, but with the speed limit roundel directly on top, so that only the corners are visible. Having a PHEV, the thing I do have to change after every update is to switch off the electric range indication (under the ... menu on the map). Otherwise it looks like I'm driving in a spot of wonderful sunshine, with murky grey clouds everywhere else!

I think the setting is off the three dots (...) on the map itself. I had trouble finding it last time. If that doesn't work, I'll have a look tomorrow.

Would you believe I've done this again! Am I really the only person who has ever done this? Assuming I'm not, here are some photos this time, as suggested by @CKO The first shows the problem (not as bad as last time, when a longer portion became detached with a larger gap). The second photo shows the wood strut firmly supporting the black part, and the L-shaped tool used to push against the inside of the body-coloured part of the bumper above (a canal windlass!), and the lower part snapped back in.

There are a number of threads where people are complaining that it picks up long removed temporary speed limits. There are no signs at all to see now, but on the M1 and M4 it comes up with 50 mph at places where there were roadworks many moons ago.

I've had it when reversing slowly if there's just a single blade of grass in the way. It's particularly annoying when reversing into a passing place on a single track road, as the driver waiting to pass must think I'm a total idiot.

I've found this to be a particular problem on single track rural roads. If I meet someone and need to reverse smartly into a passing place, there's nearly always a blade of grass there that causes the brakes to slam on (if I haven't remembered to disable that 'feature'). The other driver waiting to pass must think I'm a total wally!

The link between the ACC speed target and what TSR thinks the limit is, is controlled by a setting called "speed limit preview". See https://www.briskoda.net/forums/topic/538558-hows-this-for-good-range-but/?do=findComment&comment=6009108

You can disengage ACC from changing the target speed based on what TSR is reporting (at least you can on my 2023 PHEV). The setting is not well described. It's something like "speed limit prediction". I wasn't so bothered about it reducing to 50 when passing the site of long completed motorway roadworks ( with no signs now present). It was the automatic speeding up to 70 when it had passed the site that I found alarming. I set my ACC to 60 or 65. I think it is dangerous for this to ever get automatically raised to higher than you've chosen manually.

This works for an Octavia, so probably will also for a Superb: https://www.briskoda.net/forums/topic/538755-reset-oil-change/

I've found that, even in places where there are no traffic signs, the speed limit indication is markedly different if you have traffic sign recognition enabled. I know this, because I had a month's free trial of TSR, but was glad when it ended. With TSR it seems to be accessing a second on-line data set, different from the sat nav one. I was getting all sorts of phantom limits showing for which there were absolutely no signs for the camera to spot - mainly 50 mph on motorways for sections where there had presumably been roadworks in the past. If you do have TSR, it may be this second data set that's causing the problems, which would explain why an update to the sat nav data doesn't help. When my TSR trial ended, I found the normal sat nav data to be much more reliable.

I find Park Assist on my 2023 Octavia useful. When parallel parking, I think it can sense the kerb line (if distinct enough), not just vehicles either side. It seems to always put the tyres a neat 10 cm from the kerb. For 90° parking it's got me safely into really tight spaces I wouldn't have risked trying myself, with as many as 10 forward and back movements before it's happy! There does have to be a car either side for this - it can't interpret the white line around the bay. The problem then is how to open the driver's door sufficiently to get out!

I found during my one month free trial of Traffic Sign Recognition that the most noticeable effect was to pickup some remote data source different from the normal satnav. I also had phantom 50s where there had previously been roadworks, but now there was not a sign in sight ( on the M4 in my case). It also routinely gave me 70 mph when I was on a 30 mph road passing over a 70 one, and some other repeatable errors. It did also actually read some signs and was about 80% accurate in reading overhead variable limits on the motorway, and picked up a limited range of warning signs to show for just 7 seconds after passing them. Overall, I was relieved to go back to just the (pretty reliable) satnav indication of permanent limits.

I didn't need my email address or PIN, but it did revert my chosen measurement units. Is US gallons really the default for working out mpg?

I think that's a mild hybrid MHEV. You can't plug it in but it recuperates energy when decelerating into a smallish (48V?) battery.

Same for me. It was on version 1940 when I collected it in November 2023 and it's been perfectly behaved ever since, including getting 2 over the air updates.

Lots of cars of various makes have had the front radar sensor stolen, and they can still pass the MoT. Seems to be a particular problem with VW Golfs, and it costs £1000s to replace, so some people don't bother (particularly if they park in an area where such theft is prevalent).

Yes, good point. I really didn't expect to be successful when I started, so I wasn't thinking of recording my efforts as a tutorial 😕

I thought other Octavia owners might have had this problem, but couldn't find anything posted. So here's how I fixed it. The black plastic lowest portion of the rear bumper popped out from being connected to the body-coloured part immediately above, as a result of a light contact with a low barrier when parking. After levering up the tabs, so that they would engage with the slots in the coloured bit, no amount of pushing or thumping on the black bit would get them to re-engage, as the coloured plastic just deflected backwards. I thought I was going to have to take the bumper off, as access to the back of the coloured plastic is hampered by the steel reinforcing strut in the bumper. I managed to do if without by placing a suitable length of stout wood pressed tightly against the black plastic and secured to the ground behind the car, and then rotating an L-shaped steel bar from under the car against the back of the coloured plastic (just under the strut) as each tab position. It gave a very satisfying click when it re-engaged! Hope that helps someone (and it's a reminder to me, in case I ever need to do it again 😁)

When 100% charged, the highest electric range my 2023 Octavia iV has ever told me I have is 41 miles (=66 km). As others have said, that takes into account my driving style on recent trips (mainly level, fairly slow urban driving with the air con off). I do get roughly the range the car indicates with the same type of driving in the summer. With the heating or a few hills though, it drops dramatically.

Is it under warranty? Many years ago I had the battery fail on an 18-month-old Passat. Got it to the dealer by jump-starting it, and they replaced the battery for free. So they can fail early if there was some manufacturing fault.

On my 2023 Octavia iV I get a range of about 40 miles in the summer with the air con off and about 35 in the winter. The most electric range it's ever told me I have is 41 miles. This is on urban trips of up to 5 miles on fairly level roads. However on longer trips on just electric I've often had the car report consumption of 4.7 miles/kWh. That implies that if (say) 10 kWh of the battery is usable, the range ought to be 47 miles. It's very dependent upon gradients though - it's much lower if you have some hills to negotiate.

I found that for the month I was trialling traffic sign recognition on my 2023 Octavia, I was getting lots of phantom 50 mph warnings popping up (also mainly on M4) even though there were no such signs. Presumably it was remembering where roadworks were. But now the trial has expired, the speed indication on the satnav is correct. My conclusion is that 'traffic sign recognition' is doing more than just looking for signs. It seems to be accessing some static GPS-based dataset, separate from normal satnav one. The trial wasn't very effective for picking up variable speed limits on the overhead gantries. It only got about half correct.
