I have successfully installed an electronic start stop memory device which remembers the last over-ride switch setting (enabled or disabled) the next time that the ignition is turned on.  In my case I prefer it normally OFF (illuminated) without having to remember to deactivate the dreaded start stop function by pressing the over-ride switch every time I start the car

 

I used a Start-Stop Automatic deactivation with memory function module from an eBay seller for under £30. Beware as some sell it for up to three times that price. Search eBay for "NEW! Start Stop Memory module with SERVICE MODE! / Start-Stop SSA memory". NB The Octavia Mk3 needs the MINUS, not the plus version. It was dispatched from Hungary but arrived in the UK quite quickly. It seems very well made utilizing SMD technology and also includes the option to override the device before taking the car in for service. Here's what it looks like:-

 

 

The seller has uploaded a video to show exactly how  it works here:-

 

 

The prototype device is described in German (which Google can translate) here:-
https://www.nicomania.de/auto/start-stop-automatik-deaktivieren

 

That site includes tips on how to build the device yourself (which I have to say is not for the faint hearted - though I was tempted  but gave up at the PCB creation stage). It gives the wiring colours (confirmed by me from the official Skoda wiring diagram) to connect the start stop switch for the Octavia lll except that in my case I did not have a black and grey lead to pin 4 on the 10 way connector (maybe the higher spec models do) and this may be indeed be a +15V ignition feed but I can’t confirm that. In my case as I could not find an ignition feed in the vicinity of the switch I connected  ACC (ignition) - the Red lead on the device - to a piggyback 1A fuse in fuse-box position 48 which is otherwise unused unless trailer electrics are connected. The Signal lead (SSA) was attached to the Black and Green lead at pin 10 (Blue on the device) and Ground to the brown lead on pin 3 (also Brown on the device) - though the earth could be taken from another suitable earth point. The 10 pin plug on my 1.5 TSI SE L 5 door hatch is illustrated below where – Pin 1 is top right on the picture and pin 5 bottom right with pin 10 bottom left. The pins are numbered on the plug itself too.

 

 

Physical access to the switch unit was straightforward by inserting two plastic wedges firmly alongside the plastic lugs at the positions shown in the diagram (the lug on the right is just visible at the bottom of the picture) to create a decent gap between the cover and the housing then levering up the gearshift cover (2) using a thin metal ruler in between the wedges. The switch block (1) can be pushed up from below in the direction of the arrow and out of the cover to gain access to remove the 10 way wiring plug.

 

 

Whoopee. I'm now looking forward to activating the stop function myself as and when when I judge that it's needed - for example at long change traffic lights - rather than at silly short and unnecessary times and will enjoy re-starting the engine myself by pressing the over-ride switch to keep it illuminated - and ready for the next journey. I am still puzzled as to why the last state of the switch is not remembered by default but I do hope that this posting will be of interest to others who might hate that default start stop function in the way that I and many others do!

 

 

I'm not keen on start stop but what is wrong with pressing the switch as you drive off.?

 

It does deem a lot of work just to avoid pressing a switch.

It depends on how much you hate that particular function and can't be bothered to keep pressing the over-ride each time you drive I guess Thanks for reading my post.

Nice work Welsh Boyo.

I think you've done a great job of explaining that so that others will feel happy to have a go.

 

Thanks for your comment freedom - much appreciated - and actually it's not too much trouble to install in fact

 

why not use obdeleven to disable it without all that faffing around plus have functionailty to tweak other stuff as well? - only a few quid dearer

It's just another option for you to use it if you want I also tweak using VCDS but I didn't like fully disabling start stop - this option gives more flexibility. Thanks for reading my post!

 

it's a good device if you want to switch the stop / start back on sometimes, say in traffic  jams etc

but remember if you code it out with vcds,  you can still stop the engine the old way , just turn the key off  

I prefer not to turn off the ignition as I have front and rear dashcams to record activity around me and these would stop recording if I did that   Anyway, thanks for reading my post.

turn the engine off

keep the key in ignition on position

In my case leaving the key in doesn't keep my cameras recording as they need ignition feed.

I guess it all comes down to preference. Turning ignition off then on again is not a sensible option for me, sorry.

fair enough, not knocking the device

but for me, coding it out is best as I would never turn it back on.

 

if you didn't have vcds, then it would also work out cheaper, with the added benefit of being able to turn it back on.

" coding it out is best as I would never turn it back on" - I have a lot of sympathy with that view! It may well be the most dangerous innovation dreamt up in recent years. Some evidence for that if you search on line. As for automatic driving cars - I'm with Clarkson on that one (and I rarely agree with him on everything - LOL).

I don't think on the 2019 this function can be turned off with a OBD reader correct me if I'm wrong

It can't - from maybe 2018 model year onwards (maybe even some 2017 MY cars) as VAG have made the previously known tweaks no longer work and nobody has found tweaks that do work.

I was afraid of that    but I have seen a wired chip interface that goes between the stop start switch on the console and it turns the switch on permanently me personally I don't want to go down that route unless I have to to I rather just cold it out but you have also corrected my suspicions that VAG group have now messed with this switch stopping people coding it out

At least with a hard wired switch there is still that option, but where it's a soft switch on the HVAC screen (like on the Octavia 4) there's no way to disable/remember stop/start.
