Golf mk7: Auto Start/Stop disable switch - who wants to help?

[halfmillion]

OBDeleven - sorted

?? What do you mean?
(I also have OBDeleven, by using it you may however only disable the start/stop function)

[DV52]

Octavia RoW has exactly the same pinout used in Golf (minus version, earthed). I used for a while a copy of this circuit born2bastel >> Start-Stop Automatik deaktivieren mit Memoryfunktion, which stopped working at the beginning of our summer (poor construction quality maybe)

halfmillion: What an excellent device -it's exactly what I was thinking of doing, but couldn't !!! Big kudos to the inventor.

Can you still get the parts for this unit? If so, I'm more than happy to build it for you

Yes, I suspect that SloAu is referring to either the Voltage method tweak, or the Temperature method tweak for disabling Stop Start. It's an OK method if you only want to disable SS and if you are prepared to tolerate the "tell-signal" on the MDF every time that the car stops

If you volunteer...I'm more than happy

I may either send you components via mail, or eventually buy them on the web using a local (australian) ecomm company and have them delivered to you (maybe it is faster). Your choice!

let's do this via emails - I'll PM

That looks fantastic. Nice layout. obviously a pro. Do you want to make one up for me.This Auto Engine Stop is driving me crazy.
How much would you charge to make one for my 2017 transporter ?
I know lots of people who want to buy one of these.

^^^ frimpiny: Hi. There's been a hiccup getting the components - apparently sourcing the PC board at a reasonable price has proven to be problematic for halfmillion. So, no progress !!!

Just wanted to show off my efforts...



Many thanks to DV52 (and others).
My circuit has been installed for approx. 6 months now and makes the car far safer.
DSG with stop/start is incredibly dangerous in my opinion.
Yes, you can always try and remember to press the button...
I also agree that VW should have coded the car to remember the last setting or provided a disable option in the car settings menu.
oh, well it was a lovely little project and works perfectly for me.

For those who aren't handy with the soldering iron, I can turn the stop start off now with the software tweak on any model. It takes only 5-10 minutes and it's done over the OBD2 port, no need to remove anything.

I have my car coded for start/stop disabled
Highly recommend it well worth the cost

and what is the cost?

[Kachingg]

If your in Adelaide transporter can do it for $60
I used a kufatech module that plugs into obd port cost me about $72 with delivery
There is a thread on the kufatech module if you want to check it out

Might there be some unintended consequences of disabling auto start stop (or switching off every single time you get in the car) ? Ie if the engine/ battery etc is expected to operate in this manner multiple times in every trip and doesnt, could something else go askew as a result?

Just thinking aloud...

You use a slight (.1-.2 ltr/100) amount more fuel

Apart from that less strain on your battery/starter motor is all. I know that they are engineered to withstand the constant use but i hate the jerk you get from a start up and dsg engaging at the same time plus it does add in a slight delay off the line which could be hazardous in the right(wrong for the user) circumstance

Negative? No. Except perhaps 0.1L/100km fuel used and in return you get much longer life out of that AGM battery that cost ~$400+.
Positive? You will save on battery cost which will greatly overcome any negligible extra fuel your engine used, then later you might save on starter motor and ring gear that may need to be replaced. The stop/start system when used is not really save you money if you keep your car outside of the warranty period. If you buy a new car every 3-4years and the stop/start system is not annoying you, then leave it alone.

But, there is absolutely no harm when you push that switch every time before you start driving.

Hey Dv52, ive had a request from a few people in the US to see if we can do the same with the ESC button,

Basically pressing it for like 4 seconds after start.

Ive had a look, the button is low when in neutral state, and HIGH when pressed.
the weird thing is, when testing continuity with a multimeter, this also acts as pressing the button,

Its between VCC and PURPLE, or the wire right next to VCC

I Was wondering if you had the wiring diagram or knew where to get it to see if this is possible at all.

Cheers.
