Thank you very much Ipwrslv !!!

Some codes tell about factory numbering and the main thing is J series and L series because of two year production time difference...it could mean different design or electronic parts, off course socket is part of pcb and electronics, so it could also had this body/teeth changes. I think that 04S and 05S marking tells gateway model type. On my gateway the pin 28 is missing, also possible difference....

@ALL please if you have schematic of gateway circuit for octy 4, send me on pm, i would like to figure out this 4 signals from Ali SS electronic where is ment to be connected, to possibly prevent ecu fail that was reported. This is the reason why i dont want to connect this cable in car, because the plastic connector can be modified to fit...but if it burns my ecu than f*ck it...its not worth it...

@Djadjo78 All gateways in Octavia IV (Continental in older ones and Bosch in new ones) have missing pin 28. The 4 signals in the Ali module are for power (1, 16) and CAN BUS (8, 9).

Okay great! But how come these CAN signals can screw up gateway, on people reports not to able to power up car after connecting ali cable. I still did not connect this cable due to 6 months old car, and plastic pins that prevent connecting gray socket to car connector. Did you try Ali cable on any my23 octavia ? Tnx

I am 99 % sure the car didn't start because the Ali wire harness was faulty (short circuit, missing terminals, or terminals in the wrong position) or because it wasn't installed properly. Generally speaking - if the connector doesn't fit, don't try to connect it. I don't have experience with the Ali cable but It's difficult to "fry" or permanently damage the gateway unit, I wouldn't be afraid of that. I would be afraid that the CAN bus communication would stop working while driving.

By the way, one CAN bus consists of 2 wires (CAN low & CAN high) and must always be twisted together to prevent noise. Notice that there are no twisted wires on the Ali cable. Imho that beautifully illustrates the overall quality 😃

I was thinking to cut off 4 wires from Ali cable, and connect them to same wire numbers in oem cable that enters gateway box. But i need to try connect the scope to this 4 wires from ali electronic to see what comes out from two wires that are signal ones for Can. So in general i dont need cable/connector/socket harness. If this gets good results, than i will connect it.

The producer from your link, did the same thing…all those harness is just bypass, main thing is small black box with 4wires and can protocol controler and some ic which affects can to has some state at car power up, and listen to nine times signal to turn off memory function.This four wires are also only added to , i mean connected to current wires on cable connector to gateway.

I feel like it would be better to adjust the existing Ali cable harness and connect it to the gateway than cutting into the original harness in the car. If you really want to go this way, I recommend using the CAN bus lines behind the infotainment unit (on passenger side). There is way easier access to the cables so you will not break your back while doing it and also there is smaller risk of damaging wires important for safety.

The pin 8 on Ali harness is CAN low and the pin 9 is CAN high (same thing on the gateway), if that's what you are looking for. But probably good idea to double check, if you have the scope. If you have lab power supply, you can also try to put 28V (load dump - norm VW80000) into the Ali module to make sure it doesn't burn. If it does, it's better it happens on your work table than in the car 😃

Had the car since April and this weekend realised that there is a way to manually control the stop/start whilst driving. 
 

Apologies if it’s in the manual somewhere but I’ve never seen it or seen it mentioned anywhere on here or in other Facebook Groups. 

 

You can control whether the stop/start activates each time by the amount you press on the brake pedal. If you only press lightly on the pedal, enough to keep the car held, the start/stop doesn’t kick in but if you press harder on the pedal it will then kick in. Since realising this I’m pretty much able to stop the stop/start kicking in when I don’t want it to and let it kick in when I do. 

 

Again apologies if this is common knowledge and just me that was in the dark about it. 😉😁

Hmm never heard of that. Will definitely try it out. Thanks.

Hi my car will shutdown engine with roling wheels anyhow, i dont even need to press brake hard, i can just put weight of my foot on pedal, and it will shutdown the engine evne tho the car is still moving.

Pressing on the pedal so lightly that the start/stop doesn't kick in keeps the transmission clutches engaged, increasing the wear and tear. You can check that using the OBD tool, eg OBD11, VCDS, or ODIS.

I drive a petrol 1.5 TSI Manual gearbox if that makes any difference.

I drive the same, MY23 and the start stop is horrible. I was close to being hit on a roundabout because of it cutting the engine upon entry.

 

Not to mention it kills a new battery within 12m and these are pricey.

^^^^ rubbish on killing new batteries in 12 months.  There will be plenty here that do not just switch off stop start when they start a trip and have batteries lasting the period of the Manufacturers Warranty on the car.

I've owned 4 cars with stop/start, done ~60k miles in each over a 4 year period and never had one battery fail....

Ballcocks! A mate of mine taxied a Superb with Stop/Start in urban traffic and the battery lasted 3 years before the Stop/Start ceased to operate.

I've had 2 Octavias with start/stop, first one was on original battery when sold at 7 years old and second one is still on original battery at 8 years old - start/stop worked/works correctly on both.

My original AGM failed within 1 year - symptom was non-functioning stop/start, dealer eventually diagnosed faulty alternator and replaced both under warranty. The replacement EFB is still showing at least 85% health on test after 8 years and I always use idle stop apart from stops of less than around 10 secs.

I had a Passat with start / stop for 10 years, 80k miles and it was still on the original battery.

anyone try the burteq one yet ?

I've had it for two months now and works well. Driving mode always retains in individual, as well as lane assist off works really well and start stop is off too. You can also disable the memory module while it is still installed.

 

Installation took around 10 minutes and it worked right away. Only thing I feel like is missing that start stop would disable shutting off engine while coasting, however it is not possible without ECU remap.

Just fitted one of these for the sole purpose of not having to switch the drive mode into individual every time I start the car and it works perfectly.  Not cheap but worth it for me.

I think we have finally cracked it!!

 

I ordered one of these last week from Burteq in Chechia.

I installed it today and followed the instructions like disconnect the battery first and expect loads of scary faults on reconnection! I have only driven it a couple of times but it seems to be working!!

 

It sets the memory for stop/start and lane assist when they are disabled via the touchscreen. I haven't tried the driving mode or forward assist as they don't bother me but the stop/start was massively frustrating.

 

It took about 15 minutes to install on my 2023 octavia VRS diesel estate, quite fiddly due to the position of the module but really straightforward after watching the video.

 

Here is to just getting in a car and driving it again without having to reprogram it before every journey!!
