Disable Stop/start - VCDS tweak

[DV52]

You're more than welcome to copy and paste tweaks - people don't hold copyright over these things, and if they choose to share their knowledge in a public forum, then that information should be considered public.

So by all means, create a VCDS Tweaks thread for the Mk7 if you like (we have this one for the Mk6: http://www.vwwatercooled.com/forums/...ary-50749.html), but please provide as much detail (not speculation) as you can, along with any relevant links where readers may find more information. Also be sure to point out that any VCDS adjustments are made at the owner's own risk, and may result in damage to control modules, etc etc.

AdamD. Thanks for the encouragement. I believe that VWW already has a place for VCDS tweaks at
Forum/Specialist/VCDS Technical Resources/Vagcom Codes for Golf mk7. I was first introduced to this thread by the venerable Ryan_R.

Thanks guys, have turned off the stop start and works well...

Any body found the coding to get the traffic or tmc working ... Can't find any thing anywhere...

Also those links posted above are great...

Yep, that thread hasn't had much visibility so I've moved it into the Mk7 section for now, and shifted your post into it here:

(Bear in mind that external links are only of use until a remote site goes down, is edited or otherwise changes to become less useful. It's also more difficult to quote remote references in context, so don't hesitate to post codes and suggestions in the above thread on VWW if appropriate.)

[Ryan_R]

Agreed. If you've got time get a copy of the codes/screenshots on these forums like I did for the Mk6. No-one has yelled at me for doing them

(Just put a thanks/credit link to the source websites at the bottom).

Hi guys

Im desperately trying to turn off start/stop on my caddy. however when i go into adaptation (mine actually says long adaptation) those channels aren't listed at all.

i found some other areas that relate to this under engine, but if i do it via coding, it does nothing, and if it turn it off via engine adaption it just changes the value to active again.

any thoughts??

thanks

sprint_ed: You probably don't want to hear this, but I've done the SS tweak on a number of cars and they have all been successful. However, all the cars have been mk7 Golfs. I'm not familiar with the Caddy and you didn't say which version that you have. Without a copy of the autoscan report it's difficult to make any specific comments, but a few things that you could try:

1. Are you using the latest RT software (perhaps the latest beta version 14.7.2)? I assume that you have done all the usual stuff like a search of the net (sorry, but I had to ask)
2. Has the VCDS software supplied "labels" for all the module control on yout car (i.e. as shown in the autoscan report). If this is the case, and if you have examined all the long-coding screens and found no mention of bits/bytes relating to the SS facility, then it's fairly safe to assume that the answer (if at all) lies in an adaptation channel somewhere.
3. Have you produced a complete suite of Adaptation maps for the car? I'm not sure if you are aware of these, but the RT instructions for these maps can be found here. Remember to select "adaptation" and "CSV" before running the map software and a note of caution: the maps on some of the controllers (like the CAN Gateway for example - I assume that the Caddy has a CAN bus) can take a long time top complete - so make sure that the laptop battery is fully charged.
4. Once you have a set of .CSV files for each controller, parse them into a spreadsheet application (like excel) and search for the term Stop/Start (or Stopp as per the term in the mk7 ). That should give you an idea if there are any adaptation channels in your vehicle for this purpose. Look here for the adaptation map spreadsheet for my mk7 - just as an example.
5. If you are not comfortable with excel, then you could try simply searching through the individual .CSV files using the "find" command in a text editor software like MS notebook. It's a bit more tedious, but it does the job.
6. failing all the above, the answer could be that the Adaptation channel for disabling SS on the Caddy is in one of those "hidden menus" what we all dread. Finding the coding byte to unlock this problem is a lot more tricky, but let's hope that this step isn't required!
7. Finally, you could make enquiries about the KUFATEC module. It's intended for MQB platform vehicles, but a email to the distributor might bring some joy. The link for this product is here

Good luck and my apology if you already know this stuff. Please let me know how you fare

Disable Start/Stop (Bluemotion) on Golf mkVII - VCDS tweak
EDIT: If you have a Mk7 Golf R then you could have Acc/Start Auth. Control module fitted to your car (address 05, HW:5Q0-959-435)
This controller has only one adaptation channel whose sole function is disabling Stop/Start. The adaptation channel descriptor is Deactivation of start-stop function and default setting is not active. Change this to active

Hey mate, trying to disable the start-stop but changing the above setting just constantly sets itself back to not active. Not sure if it matters but my HW is the same as above but suffixed with an "A"?

Any ideas?

Update: The temperate method also seems to be unable to be modified, I have disabled via the voltage method.

Now, how the hell can I turn off Driving School Mode? I have reversed all the instructed settings but it wont go away!!

Jonoz: Hi, you sound a bit frustrated!

The Acc/Start Auth is a relatively new control module (it's not in my car), so I can't provide much help (unfortunately). Perhaps someone else here that actually has the module in their car can lend some assistance.

Not sure why the temperature method was unable to be modified, because this is the way that I disabled Stop/Start on my car. I used the exact procedure in my post - worked first time without a hitch. Stop/Start has been disabled now on my car for almost 12 months without any problems.

I've had a few PMs from others and there are some posts both here and on the Golfmk7 site from members that have also been able to make the temperature method work. Yours is the first time that I have heard that the temperature method has been unable to be modified. But it sounds like the Voltage method has worked so all good I guess!

OK, now for the other problem of the attempted driving school mode roll-back.

Please provide more details about what happened when you tried to roll-back the settings. For example:

1. What RT software version were you using?
2. What type cable are you using and is it the same cable that you used to enable Driving School mode?
3. Have you looked at the three adaptation channel settings after you finished the roll-back procedure to confirm that the control module actually accepted the changes that you made?
4. Have you looked at the CodingLog.txt file in your debug directory to make sure that another adaptation channel wasn't inadvertently selected in the roll-back process?
5. I'm not sure that I understand your comment, "it wont go away". If I don't want to use the facility, I simply select another screen using the <, or > tabs. Driving school mode just stays in the background without affecting any other function. Does this work on your Discover media screen?

Thanks for the response DV, other Audi forums people are speculating in later models (MY15) the temperature method is locked out.

As for DSM, left the car powered off for 10 minutes after making the change and powered it back on and its gone. Reason for wanting it gone is that it was the default display when selecting the "CAR" option.

Johoz: Glad to hear that it's all ok now.

And you are correct, the Driving-Mode screen does become the default page when the CAR button is pressed (notwithstanding that you can still navigate to other screens using the < and > tags). I'll put a note on my tweak page instructions to advise others about this. Thanks for highlighting this point.

The voltage method is the only one that worked for me to disable the stop/start, was locked out from modifying the temperature. Mine is MY15 R, September 2014 Build.

Fontana: Thanks for the feedback. From what you and jonoz have said, it appears that the voltage method applies to later model cars. I'll add a note to my tweak instructions. Again, many thanks

This works perfect, relatively cheap, very easy to install and completely reversible

Coding interface disable start / stop MQB-40019

[dtpearson]

I had my MY15 Golf R VAGCOMed to disable the stop/start by the voltage method, and now i find that it sometimes interferes with launch control. I find that sometimes when i stop to do launch control the stop/start symbol comes up on the dash where the S1 symbol usually is, the car will not launch properly then.

I have to press the button to disable stop/start (even tho it never kicks in) to keep it from interfering, so no big problem, but i though i should let everyone know.

..EDIT: If you have a Mk7 Golf R then you could have Acc/Start Auth. Control module fitted to your car (address 05, HW:5Q0-959-435)
This controller has only one adaptation channel whose sole function is disabling Stop/Start. The adaptation channel descriptor is Deactivation of start-stop function and default setting is not active. It may be possible to change this setting to active (untested).
I've had two replies from forum members about changing the setting on this control module (thanks jonoz and fontana). Both have advised that they were unable to gain access to this module.

I dont have a MK7 but will shortly be collecting a new Touareg. I will be wanting to kill the start stop. Any thoughts on whether a MY15 Touareg will also have the Acc/Start Auth. Control module?

I am also wondering if lack of access to the module is related to number of KMs on their cars. I read elsewhere that the ability to disable S/S may be allowed initially, so the car can be configured for its specific market. Then this capability is removed after the first 50 or 100kms on the ODO to stop people like us from fiddling. I wonder if this is what jonoz and fontana were seeing. My car will have ~ 25kms on the clock when I get it home. My plan is to go looking for this or a similar module straight away to see if it is accessible.
