Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before. We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

    400 Bad Request

    I've been reading up on the Auto Engine Start/Stop feature on the new Tiguan.

    Apart from being annoying, it doesnt really sound like it helks with fuel efficiency.

    Is there a way to have this feature off on default?

    Someone with a VCDS cable or OBDEleven dongle should be able to assist. Not really switching it off but changing the voltage of when the feature kicks in so it never kicks in.

      I don't find it annoying at all but people who haven't used it seem to think it is. I agree with you though that it most probably saves bugger all on fuel.

        My understanding is that this feature is used by pretty much all manufacturers these days and contributes to their claimed consumption figures based on certain driving conditions. To be competitive in the fuel economy area which is pretty hotly contested, manufacturers enable the feature, but in order to be able to use start/stop in their figures, it can't be disabled by default, leaving pretty much every manufacturer to have it enabled without an option to disable it. To be honest though, it doesn't really bother me now that I've got used to it.

          C'mon ... who said to you guys it is about fuel saving?

          It's about CO2 emission, especially important in city traffic. When you drive out of cities, you can always switch it off.


          About changing voltage to disable S/S - it's worst method. You can invert it action, in way that S/S is off by default, but you can always turn it on.
          Not tried on Tiguan, but few months ago my friend asked me to do some coding in his Audi A4 2014 - he had step by step instruction.

              I can't begin to imagine how it could annoy anyone that much, 1st world problems I guess. Actually if you brake gently enough the start/stop does not detect the stop and the motor continues to idle. I suppose it does not annoy me because it usually does not engage due to soft braking and if it does engage I don't mind sitting there without the motor running.

                This is also my standard operation, WHEN I REMEMBER TO DO IT.

                It not only annoys the crap out of me, it has proven to be dangerous on a number of occasions, when, not being use to the slow response, I have gone to move into a break in the traffic at a roundabout and nothing happens and then the Tig takes off, putting me in the worst possible position.

                This is the only feature on the Tig I do not like.

                  You don't need to turn it off, just brake fairly softly and it does not work and so it won't annoy you. I must admit the angst this causes amuses me somewhat but each to his own. I have never had it cause any delays on take off, nail the throttle to the floor and it just leaps off the mark.

                    drivesafe: I entirely agree. SS is without a doubt the most dangerous aspect of VW's vehicles - especially when completing a right hand turn against on-coming traffic. Those few seconds that it takes the engine to crank-over, start and then accelerate can be the difference between a near-miss and a catastrophe!

                    Sure (as some have mentioned here), it is possible to "trick" SS into not switching-off the engine by not turning the steering wheel too far, or by doing the "SS soft-shoe-shuffle" (i.e. finding the sweet-spot in the brake press where the car is stopped, but SS is not engaged) - but IMO, it's far better when driving to concentrate on the road conditions, rather than to have to think about how to defeat SS.

                    And yes - it is possible to defeat SS, by remembering to switch it off before starting the journey- but this shouldn't be necessary in the 21st Century and in a car that is...........well........... not cheap! Why the f#ck didn't the boffins @ VW design the SS off/on button so that it remembers the position at the last ignition switch-off - this isn't difficult to do and it is done with some of other buttons in the car!

                    Anyhow, rant over - solution mode now! There are 3 x ways to fix the SS problem: First if you have access to a diagnostic cable/dongle (VCDS, OBDeleven,VCP etc.) there are a couple of tweaks that will work on MQB platform vehicles like the Tiggy. Second (and much better in my view) is to build and install an auto-Start/Stop kill switch - it's not difficult and it's relatively inexpensive see HERE. Or, you could buy and install a commercial product like THIS (it simply plugs into the OBD port under the dash-near your right foot pedal)

                    Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is in the forum proper. That way you get the benefit of the wider expertise of other forum members! Thank you.

                      The braking method that defeats it is the correct way to brake any car and is taught by or used to be taught by the best instructors. I used to teach advanced road craft and competition track driving and it was the first thing we drummed into the students for road driving. I understand that very few people get taught driving properly and I bet none of the L plate schools teach it either. The plus side is that the passengers do not feel the vehicle jerk to a stop and have a far easier ride. Don't knock what you haven't tried. BTW track driving is the exact opposite, jump on the pedal and try and bend it then modulate to avoid lock up.

                      I dispute the SS causing problems in traffic and my experience is drawn from three different drivers, two of them used to compete and using two different cars over at least 60,000k. I think that if you know that the system is unreliable you should allow for it in your driving and not expect the car to come to you but as I have said before my experience is that there is no delay and that is from more than one driver in two cars. I used to drive Ford Transits with auto and they had delay deliberately programmed into them so the drivers had to adjust to the delay, this was a deliberate ploy from Ford to eliminate abuse of the transmission and it is curious how anyone who drove one quickly came to the conclusion that they had to adapt or die.

                      My further observation is that without exception every one of us thinks we are perfect drivers, I have never met anyone who thinks otherwise until shown they are not, self included. I have sat beside drivers that amazed me how good they were over many hours and wished I could emulate them but it is never going to happen. Sorry to go off topic and rant over, subscription ended as there does not seem to be any point looking at this thread any longer.

                        Hi Ozsko, and each to his own, but I, like most people, do not buy vehicles to to drive them to suit the vehicle’s needs.


                        I buy them to drive them to suit my needs.




                        Hi Don and thank you very VERY much for the info you put up in the link to your other thread.


                        I had contemplated the VCDS route but I am testing some equipment and will occasionally actually need to have the STOP/START operating so I can compere the results under different operations.


                        To this end I had already started to design an electronically activated over-ride for the STOP/START switch, using the same type of mini reed switch, and your post has just made my job so much easier and quicker.


                        Again Don, thank you very much for taking the time to post up that thread.

                          If you don't use the brake hold, the engine starts as soon as you take your foot off the brake. I've never been caught out in about 6,000 k's of driving, admittedly mostly medium traffic.

                            This a really bad thing to do with dual clutch gearbox. Don't creep forward in traffic. Remain stationary and let a gap appear in front of you and the go forward. Yes, someone might jump onto the gap but I am only talking about the gearbox. Creeping forward place strain on a DCT with clutch slip the same with a manual.

                              Drivesafe: I'm intrigued by your project and I hope that it's a generational improvement on my amateur effort!

                              Not sure if you are into programming Arduino chips, but an embellishment to the third incarnation of my Auto SS kill switch is to include a facility to shut-down the device entirely by holding down the SS console button for 5 seconds on ignition switch-on. This is useful when taking the car to the dealer for maintenance (I have to repeatedly explain to the dealer service manager at every service that SS disabling is not a fault - regardless of VW's continuing belief that it's not possible to automatically disable SS)

                              The code shouldn't be difficult - just a matter of sensing the console SS button at ignition switch -on. The newer version of the Digispark chip now contains an EEPROM, so this is an ideal application - the maintenance state can be toggled ON and remain in that condition until the console button is held down again for 5 seconds (after maintenance has been completed) - thereby re-energizing the auto SS kill switch.

                              Anyhow - just a suggestion for you to consider and I hope that you will include details of your device here
