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,

  • 2008 R36 - transmission jerk when moving off

    so...

    this car is turning out to be more problematic than i hoped...

    one of the things that annoy me is that when i'm moving off from the lights, doesn't matter if i feather it like i'm very gently trying to not squish some silky tofu under my foot, or drive it like a normal person would, it seems to jerk when moving off.

    it's not ALWAYS the case, but like a 50/50 chance.

    i'm hoping someone has come across this before and might know the answer

    right now, i'm thinking that the transmission mounts/bushings are not so far the end of life. which got me asking how much they'd set me back to get them replaced. come out to a little over AUD$1.3K

    but i'm keen to hear what other owners have come across before i go ahead and do it.

    what bushings/mounts i get is another discussion, assuming that i have to do it, so let's not go down that path for now.

    Sounds like a dsg clutch pack issue.

      I'd say its probably not the mounts or bushings. It's possibly the clutch pack inside the transmission. A faulty mechatronic unit can also cause jerky behaviour.

        So I’m guessing this isn’t going to be a cheap fix?

        Any guidance on what it might costs?

          How many KM's on your car?

          Keep in mind that this is one of the earlier DSG's. They were a very new concept at the time.

          I'm only guessing here but clutch pack would probably be a few thousand, mechatronics unit would be $5-7k.

          You mind find that the behaviour improves with a relearn, or if you try using the Auto Hold.

            It’s just under 240k. I’m the “no idea how many”th owner. So...

            How do I get it to relearn?

              At your kilometres I would expect the clutch packs to be well worn and probably in need of replacement.

              The DSG can be reset through VCDS

                Mechatronics is $2700ex from VW.
                Clutch basket complete is $900ex.
                Mechatronics can be replaced in situ. Clutches is gearbox out and requires a careful measurement procedure to ensure the correct clearancing shim is used.
                Add new filter and fluid plus labor costs.

                After clutch or mechatronics replacement basic settings needs to be performed in it's entirety to adapt the new parts:

                  thanks for the direction.

                  i've got the car booked in to get the AC compressor replaced next week. if i can't get that working, i won't bother with anything else.

                  if that works, then i'll do the mechatronics box n clutch n transmission mounts.

                    Interesting, those parts prices are surprisingly reasonable.
                    Do you know what the labour hours might be?

                      i've been quote 3.5 - 5.5 depending on if the mech unit needs to be swapped out. if i do it, will swap out all the mounts as well while it's apart.

                      kinda of a "might as well" situtaion.

                        Lots.
                        Mecha I'd say you'll be up for 3-4 hours, clutches is gearbox out so a day.

                          Hmm ok. Add $200ph dealer labour and 10% GST and that should give you the total cost.

                            so, i was wondering if gearboxes for VW are interchangeable? if so, might go hunt for a newer one?

                              Yes they are, but the ratios need to be same (ie engine/gearbox combination dictates the gear ratios).
                              So if you get a gearbox from any other R36 you will be fine.
                              R36 has shorter ratios than B7 FSI V6 Highline for example even though the driveline is essentially the same - for better 0-100 times.
                              So you can get a gearbox complete from any R36 and swap it over. Nothing further to be done in terms of calibration, coding etc.
                              Or you can get a mechatronics from any PQ platform DSG6 car, then flash it with the correct software for R36 and then perform basic settings to learn the clutch and gear characteristics.
