Thanks, I got it done. I needed to put the unlock choices in the MFD, for some reason they were not there.

Default Help with 2014 Passat HHC and seat-heater settings?

I figured out the seat heater / car restart question, but my hill hold control confusion remains. Fixing the problem I had that the seat heaters wouldn't turn on when I started the car to the same settings they were at before turning the car off was fixed by either the recent firmware update Ross released for the HEX-NET, or something that changed in the VCDS software between versions 14.9 and 14.10. I'm not sure which of these updatws corrected the problem, because I applied both at the same time. I simply re-saved the "on" values after the updates.

Having read the TDI-Club FAQs, messages in this forum, the Ross-Tech VCDS manual and the results of several Google searches, I still don't entirely understand the differences among the three hill hold control settings, "normal", "low" and "high".

Since the hill hold control can't be entirely disabled on the 2014 Passat, can someone explain the difference between the 3 settings, "normal", "low RPMs" and "high RPMs"? I'm confused between whether low means that HHC is disengaged (lets go of the brakes) at low RPMs or engages (sets the brakes) at lower RPMs than the high setting. Normal seems to cause my 2014 Passat to wait for fairly high RPMs even when stopped on a level street.

Basically, I want HHC to stop "helping" me as soon as possible, because it's a pain in the butt. I just need help understanding whether the "low" or the "high" setting in VCDS will achieve that goal without wasting more fuel than I have already by trial and error...

Thanks for any help!

Hey does this adjustment also correct for speed? I've checked my speed with 2 different GPS's and they both confirm that while the car indicates 100km/s I'm only doing 93km/h!!

Set your hill hold to low, for a low amount of assist.

I wish they could find a way to stop the 39F indicator. It becomes quite annoying when you have to hear it every single time you drive in the winter.

Does that freeze indicator default on? Never heard ours, although the little "snowflake" appears in the MFI. These cars don't really appear to come set up the same from the factory. Our remote start doesn't work and the automatic wipers don't either (although I realize these can be turned on with VCDS).

Are you sure you are using remote start correctly? On my 2013, you have to push lock-start-start, and it won't work if the CEL is on. Not terribly intuitive, but it does work.

If you start the car with the temperature already <40F, the MFI will only flash a few times. However if the temperature is >39F when you start the car (like in my garage), then you go out driving and the temperature drops the MFI will ding, go to full brightness, and flash.

Solution: don't park the car in the garage.

Why does the car feel the need to tell you that it is below 40 anyway? I am pretty sure most people don't care, unless they have to be outside in it. Once the car warms up who cares.

Because of the potential for slick road surfaces.

On the way home from dinner last night at about 9 pm, my 39 degree dinger went off as the Polar Express swept through. Really, does it need to announce itself that way! I thought something was wrong with the car! Just one little beep will do. Plus at 39, the roads are still warmer than the air. Let's see what happens on my drive to the office this morning.

39F on the shade with wind have a good chance of being slippery.

Yes, I've tried that repeatedly. Made sure all the criteria in the manual are met, etc.
