Just to help settle your mind. Here is a Polish website showing the base model gets ESP with ABS, EBD, MSR, ASR, EDL, HBA, DSR, RBS, ESBS, TSA, XDS+ as standard: https://www.wyborkierowcow.pl/nowa-skoda-octavia-2020-opis-wersji-i-cennik/

That is very interesting and the text from the Polish spec is encouraging. The mention of XDS+ suggests that an upgraded version this is now standard on all Octavias rather than just a fitment on the 4x4s when my current vehicle was new. Why can't Skoda UK be as informative now as they were then?

 

The video however, I think, shows the Haldex in operation rather than the EDL, but maybe it shows the interaction between the two.

Best drive one and see if there is actually a case of 'less good handing' 

?

Drive the car up a 60 mph NSL road and go around corners and then tell us if you are getting understeer.

Up that a few MPH and see how any 'Emergency Services' drivers / crews will be getting on if they are driving standard models and not 'Blue light' specials.

 

Thanks for your helpful comments.

Well - I can't clarify or verify anything because I just don't know. That's exactly why I have been asking.

 

You asked the dealer a question and got the following answer:

I asked the salesman at a local dealership whether it was fitted to the 4x4s and he has just come back with an answer that it is NOT fitted. Apparently it is only fitted to the 245PS petrol engined models.

 

It's not clear what 'it' was in your question. At a guess, you asked which models get the E-LSD (aka VAQ or mechanical diff) in which case yes, I'd agree that only the 245ps has it fitted.

 

EDL and XDS are separate and distinct functions, please stop using them interchangeably as it's only confusing matters. To recap from earlier in this thread:

- EDL uses the brakes to transfer power to wheels with grip (brakes the spinning wheel to transfer power to the non-spinning wheel)

- XDS (torque vectoring) is an extension of the EDL+ESP systems, it'll use the inside brakes while turning to reduce wheel spin and maximise control/drive through and out of the corner

It is showing both the haldex and EDL in action.

- The haldex is responsible for moving power to the rear diff, it does not and can not transfer power left/right.

- The front and rear diffs are open so EDL is responsible for transferring power left/right across each axle by braking the spinning wheel.

 

When only the rear left wheel has traction (46 seconds), the haldex is moving power to the rear but as it's an open diff, the power takes the path of least resistance to the rear right wheel and the car doesn't move.

When the offroad mode is selected, this makes EDL kick in more aggressively, braking the rear right wheel to transfer power to the rear left (62 seconds) and the car moves.

 

Sorry for the long post, but I feel it's important to understand what these systems are as it'll help you find the right question, and hopefully answer.

 

I think your question should be, do the MK4's (specifically the 4x4) get XDS, bearing in mind that:

- XDS is just software on the ABS module

- by the end of the MK3 production, it was standard on all models

- the Polish site states all MK4 models have XDS

- there is no mention of ABS or ESP in the UK brochure but both are fitted

 

I would be amazed if the entire range doesn't have XDS, especially those with a haldex fitted

Firstly, yours if the first answer which really helps.

 

I know you took slight exception at my confusion of EDL and XDS, but this is in the absence of any clear information previously about the difference. You appear to know the answer which is great, but that is what I have been seeking and not finding anywhere. You can't know stuff until you do!

 

It is encouraging that you believe that XDS is fitted to the entire range, but I feel like we are back at the beginning of my question, albeit with a better understanding of what I am asking - that is, does the 4x4 have XDS fitted? I have never seen it said that anywhere it was standard on all Mk 3 models.

 

I do understand that you think I am being unreasonable in expecting to know this for certain, so probably there is no point trying to know the answer other than to accept people's assertions that it is likely that it is fitted. And indeed why should one bother trying to find anything out for certain? A fool's errand obviously!

It's in the Nov 2017 brochure where the S was the base model:

 

 

And the Nov 2019 brochure where the SE Drive was the base model:

Don't let me dissuade you from your quest! I'd love to hear a confirmation from Skoda that these technologies are fitted across the range

 

I'm just highly cynical of the knowledge of some VAG group staff when it comes down to spec. Even more so when VAG seem to deliberately use misleading or confusing terminology that can change between brands or models.

 

If nothing else, hopefully by explaining what some of these technologies are, you'll have a better chance of getting an answer rather than just being fobbed of with misleading or incorrect info

Roll on to the present and I have been trying to find out whether the modern equivalent of XDS is fitted to the new 4x4s. I believe that this is called EDL or EDL+, but there is an absolute absence of information about what these amount to.  2014 4x4 Diff lock.pdf 25.6 kB · 3 downloads

 

As I understand it, the current version is XDS+ which brakes the inside rear wheel, as well as the front one, when cornering.  It's fitted to my wife's current Karoq 190 TDI and it rotates with considerable alacrity and ne'er a trace of understeer when driven briskly or otherwise. 

 

HTH

Wouldn’t the best thing to do be to test drive the various versions? Then you can compare with your Mk3?

I'm sure the carwow review said something about 90% of the traction being sent to one wheel if needed but could be making that up. I'm sure they're all individually controlled should traction be an issue.

As always I'm late to the thread, but I remember seeing this a while ago. It's quite interesting seeing how the different wheels get traction when two or more wheels spin freely.

It's not as quick a transfer of grip as I'd been led to believe.

EDIT: Just noticed Langers beat me to it with the MK4 test. Bah!

Hat tip to langers for beating me to the video.

Bump. For @Mattyboy91

Interesting to see that there's quite a big improvement between the MK3 and MK4 Octavia Scout, so if you need the off-road ability, the MK4 is definitely the one to go for.
