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,

  • Mk7 Stop/Start System - Issues and Questions

    For the last two days I have been unable to get this function to work. Usually it defaults to being on unless you turn it off. I have turned the switch on and off several times, driven with A/C on and off. I have driven the car often enougn to know I have a problem.*I know some of you hate this function but i'm a fan of it. Anyone else had problems with this feature?

    Man, many would pay for it, to get that to be switched off.

      Out of interest, has it been hot where you are the last couple of days? I know with our Touareg, at one stage we thought it was broken, but then realised that it wasn't turning off because the aircon was running..

          Maybe your battery isn't fully charged? It won't work if the car hasn't been driven for some time.

          Is the car up to full operating temp?

            Mine comes and goes — I suspect it's controlled by measuring the current draw and comparing it to the state of the battery.

            It must always be certain of a restart — if the conditions are not met the engine continues to idle.

            I've noticed that VW systems in general seem to maintain the battery at about half to two-thirds charge, which I've heard (though I've yet to see it proven) makes the battery last longer.

              Thanks for the replies. Yesterday I was driving for 90 minutes so I woild hope the battery got a good charge. It hasn't been warm in SA so I've only used tne air some of the time.i am going to VW on Monday to get the waste gate clip installed so if it's still not working I will get them to check it out.

                RTFM - Read the manual, there is a list of requirements that have to be met in order for the blue motion to work. If it's hot in the cabin, AC on high, heaters on high, battery voltage, moons of jupiter in alignment……...

                  could also be the DPF doing a regenerate if it's a diesel... our Passat doesn't turn off when it's regenerating...

                    And just like that it's working again. 4 days of nothing and then it starts working again.

                      Mine comes and goes. On occasion I will attempt to turn it on when I am stuck in traffic and get a message on the dashboard "engine must be switched on" - it's no the end of my world but it is another of the frustrating issues with this car.

                        Just took an Audi A3 and and S3 out for a test drive, both cars had that function stop/start, we had the air-con running on both test drive, in the A3, it didn't stop the engine at the lights until we turned off the air-con, but was surprised when the S3 shut down the engine even though the air-con was on, that's a strange feeling given it was a manual, basically as soon as you engaged the clutch, the engine fired up again.

                          How is it an issue?... if it is working as intended?

                            ????? if motor is not running lift your foot off the brake a bit

                            My aircon is never turned off and the stop start works all the time.

                            If I don't want it to work I just don't hold the brake down so far and engine keeps on going.

                            Or if I want it to start before the lights change I just lift my foot a bit and we are ready to roll.

                            Just a matter of getting used to it.

                              If you go into the car menu on your centre console there is a screen that will tell you why the Start-Stop system isnt turning the car off.
                              Can't remember exactly where at the moment because I'm not near my car.
