      I'm driving a b6 Passat with auto trans and the auto hold feature that holds the car when you come to a stop. I"m looking at a later model sportwagon which does not have the autohold feature due to a traditional handbrake. Is there any way to add autohold?

      Do you mean hill hold so the car doesn't roll back? All GSW/AT in north america have that, I think.

      theres lots of discussion as to whether its "autohold" or "hillhold" in my actual vehicle, its called "autohold" and it is used anytime, in stop and go traffic etc, no hills have to be present for it to work. The purpose is to ease your leg in stop and go bumper to bumper. It works on flat or hills.

      Oh yep that's not the same then but I get the idea. My alltrack doesn't have it and I don't think my family's 16 GSW had it either, but every MK7 I've driven does have hill hold for what it's worth, even with the mechanical handbrake.

      GSW & Alltracks don’t have Auto hold feature from factory. As everyone here already knows they have only hill hold. Now they CAN be retrofitted with EPB system if someone wants to go down that path.

      As the OP and I both have a B6, we have both Auto hold and Hill hold.

      I’m in a Euro B6 R36 wagon with full Euro B7 electronics.

      On the RoW Passat B7 EPB4 3AA907801 there is an adaptation channel, which enables the Auto-Hold menu in MFA, which lets you choose between having autohold on by default, off by default or the default behavior which includes Hill-Hold. Late-model B6 with it's 3C8 EPB3 might or might not have it.

      In the CCM (I believe) there is a long coding to turn on autohold always on. There is a separate coding to make it an option in the MFD if you have an MFD.

      When you get in the car you have to click the seatbelt and it turns off. The same feature seems to hold the car when stopped - for me- as I have a manual, it also does hill hold. I think these are all built into the master cylinder - i.e. its not the EPB engaging the motor like when you turn on the EPB.

      Most in North America have it turned off by default - mine certainly was.

      I could also be mixing this up a bit but I’ll try to find the long coding for the autohold “always on” and post.

      Yes, but can someone answer my original question as to whether its possible to add it to a vehicle with a traditional handbrake. I know you said its not tied into the "E brake" but a function of the the master cylinder. Am I on a fools errand, or is this something someone with proper knowledge could accomplish. Also since there is no dedicated "autohold" button, I assume a button or switch would need to be added somewhere on the dash or console.

      Not sure about the programming, however cars without electronic parking brakes have hill hold which uses the abs system. In theory, its possible.

      Sorry bro, Hill hold is yes accomplished thru the ABS but Auto-Hold is accomplished by the EPB system. You need EPB in order to have Auto-Hold.

      The Passat uses a TRW ABS pump/controller, not an ATE that is on the Golf.

      auto hold on the b6 Passat is accomplished through the ABS. I had a B6 Passat with 6MT and rarely used auto hold.

      We have a 2015 Golf Sportwagen and 2017 Alltrack. Both have manuals, traditional hand brakes, and the hill hold feature. I have been driving VWs with manuals since 1972 and it is a great feature! But it isn't an addable feature, it has to be built-in from the factory. Between the cost and possible malfunctions it isn't worth trying.

      The OP isn't asking about hill hold, he is asking about Auto-hold - where you come up to a stoplight, stomp on the brakes and you can remove your foot. The brakes will remain on until you want to go.

      Exactly, and by the way, Hill-Hold can be added too.

      No it's not accomplished through the EPB system. You don't hear the EPB whirring into action every time you come to a stop and the motors whirring when you go.

      It is the TRW ABS controller applying line pressure to all 4 calipers to hold the car.

      If you're at a stop with auto hold for a long enough time (3 minutes), then eventually the auto hold shuts off and the EPB engages.

      If you remove the seatbelt with autohold, the EBP turns on.

      After some testing in my wagon & Tig, You are correct and I am mistaken. It’s also funny that only cars with EPB have Auto-Hold available.
