    VW T6 4motion esc disable

    I would like to disable ESC on my VW T6 TSI but when I go on abs module and ask for long coding help it says that my car is not supported.
    Attached a scan of it.I’m using vcds 16.6

    On that one I have a lot of DTC because I try to change the last two digit from 00 to 01 ( 04 also do the same all the other digit are rejected). with that ESP is disable but I get orange light on dash for no esc,no abs, tyre pressure and all sort of DTC because of disable ABS.
    Will you bring the Long coding helper for the T6 in futur?
    If so when do you think it will be available?

    The Esc on the T6 is very intrusive and you can't disable it with ASR switch like I could on my old T5.
    I'm going crazy with that thing as on mountain road it activate the brake in every curve because it think's i'm too fast.
    Also on snow when pulling brake to make tight curve the ESC make the Van pull straight. Already end up in a snow wall.

    I would also like to know if it's possible to change some setting so that I can left foot brake?

    First of all, please change the coding back to it's factory setting - playing randomly with the values is really a stupid move.

    Yes. ESC cannot be disabled via coding though.

    Once we're satisfied that it covers all options/models and is ready to be in customer hands.

    All T6s have driven so far (incl. my own) have actually a very good ESC setup and I have not had a single case where it acted up! Since you emailed us the full scan, I went through it but couldn't find anything obviously wrong with it.

    Based on your description, I may be stating the obvious here - but did you consider that the problem is you and not the car?

    Hi Thank's for your answer.

    So I just went for a test with the T6 on a dirt road with the ABS, esc, disconnected by putting 01 at the end off the long code and now it's finally nice to drive.
    I can pass curves side way drifting on the dirt with no interference from tarction control.
    I try to pull e-brake to take some tight curves and it's also finally reacting naturaly ( opposed as with esc on where it doesn't want to turn with e-brake).
    So i think, like that it will work perfect for the winter where I leave in the french alps.
    I'm fifty year's old and in the winter the e-brake turning on snow and left foot brake have save me so many time when having spirited drive on snow/ice on my 34 year's of snow driving.
    Last week I went up to the alp's and in every tight curve driving fast it was breaking before me and when I want to go WOT at the apex their is no power until wheel's are straight.
    My van is on OZ ultaleggera 19' with 4 michelin PSS 255/40 and KW V3 coilover's and at the moment it's making 280hp and 420Nm on Oem turbo waiting to fit a LOBA LOCO-04 turbo to get some real power.

    Before that T6 I had a T5 V6 3.2 24Valve 4motion with schrick cam's, supercharger, AWIC, Methanol injection... running with E85 making 450 Horse power. On that old T5 when I pressed the asr switch it will also disconnect the ESC. that was great.
    Could enjoy driving sideway's on snow and a bit fo drift on dry B roads
    That's what I would like to be able to do with the coding, having ESC/ASR disable when I pressing ASR switch
    Because at the moment it's so frustrating when you arrive full speed in a curve and that you want to brake at last moment to have a good weight transfer to front to initiate a bit fo drift and then go WOT at apex but the esc decide to brake before you!
    So at the end it's not you who is driving and you get super slow compare to what you are used to.

    My Esc have nothing wrong it's just that VW set it up for people who don't enjoy driving or don't know.
    At the moment it's not even possible to have 5 degree of oversteer on snow without having the ESC kick in to put it back straight so if you are used to drive with some drift to initiate curve the ESC can then become dangerous
    because it will open your trajectory.
    So the solution I find now is not perfect but so much better for me than OEM.

    Before that I try some other solution:

    -removing ABS 30 amp fuse in engine bay. It was really bad as then I also didn't have airbag and fuel gauge.
    - disconecting one of the Abs sensor same effect as 01 in the coding but more time consuming to change.

    You say:
    "Yes. ESC cannot be disabled via coding though."
    But I see they can do it on Golf 7, their are different option off ASR switch.

    Thanks for giving us some more background. It would have helped if you filled us in a little earlier than that, if the customer doesn't state otherwise we normally assume that a system is faulty - and start looking for the culprit. In your case it's working exactly as designed - except the problem is you and not the car.

    As for your solution/questions... What you changed in the coding is the type of wheel speed sensors, which results in an error being detected and the system going into failure mode. In that case, everything related is normally shut off - so ABS, ASR and ESP/ESC should now be completely offline. On MK60EC1/MK100 (Golf 6/7), there are options for different types of shut-off switches and their behavior - the reason for the existence of such options is simple, there are Audi/Seat models which have a rather aggressive target market while VW/Skoda is more on the conservative side (GTI/R models excluded). So while those systems need to cater to a broader audience, they contain options to do so. The T5/T6 doesn't have such variants/models, so there isn't a need for such options either.

    That said, VW/Audi has always had the ability to disable systems when needed and since the T5/T6 is highly popular for all sorts of conversions those need to meet the requirements and also have proper ESP/ESC setup if required by law. An interesting read in that regard is the "Volkswagen Nutzfahrzeuge – Aufbaurichtlinien T6" (see chapter 2.2.6 for general information & chapter 2.2.6.5 for ESC disabling), which also explains what is possible (and possibly legal) and what isn't. To sum things up, what can be done is disable ESP/ESC but keep ABS/EDS/ASR working, if unavoidable this can be further degraded to ABS/EDS. Neither of these is done via coding though.

    That said, any of these changes must comply with the European Union's regulations. In your case, disabling the system like this is simply not legal and while this may be your personal desire - you probably should take your driving skills to a closed track instead.

    Please understand that Ross-Tech will not assist you with any of these steps for liability reasons and we specifically discourage others to use the above method as it has way too many unwanted side effects (aside from the legal concerns).

    Exactly the problem is obviously me wanting to use this Van as a rally car as I need to carry lot of ski's in winter. when I'm not carrying big stuff I have

    - Audi RS2 full modded with V8 Torsen in rear wide front tyre and narrow rear tyre.
    -Toyota GT86 with shitiest tyre I can find in rear and michelin PSS in front for drift.
    - Toyota Hilux 3.0 D4D 310HP 620 nm rear wheel drive with rear LSD that one is in thailand where I go for work often.

    From what I understand when I google translate this is no option to desacitvate the ESP.
    So I guess the best for me is to put a switch on the dash that cut the connection of one of the 4 ABS sensor like that when I switch it off the ESP, ASR and ABS are out of order.
    Perfect for slippery road's or when I want to have spirited drive.
    And when back on highway cruising I flip that switch that abs sensor back on to get all the driving help's back.
    I had something like that on An old Subaru STI

    Took a while to find, but try this instead...

    Volkswagen Commercial Vehicles: Body Builder Guidelines for T6

    ...before you install the switch you may want to do a dry run, I doubt that it will work that easily as you will at least need an ignition cycle or maybe even to clear fault codes.
