Oooh. My first "RTFM" here in this forum. Thanks! You should know I did read the manual and I have yet to find where it says the engine WILL shut off when simply placing the shift lever into Park. In fact, shifting into Park is only step 3 of the "Stopping the engine" procedure and step 5 is press the Start/Stop button. So as best I can tell it shouldn't shut off unless I press the button but it does some time.I imagine if the OP looked, he'd find in the manual that this is nothing more than part of the stop-start mechanism
Not really the point here but it's definitely cheaper to ask if someone knows the answer first.OP, if you don't want to invest $200 in your $40,000 car to have the opportunity to know what's going on then just take it to a dealer.
That's only partially true. I expect a car to work *normally* and not do one thing one day and another thing the next day when I didn't do anything different. In my case, different days bring different outcomes which is not how a car should normally work.This is clearly a problem with expectations.
That is not what I said. I said it's doing what it wants when it wants to and I'm trying to understand what that is. It should not necessarily shut the engine off if I put it in Park. However.....The OP believes that the car divines when you want to shut the engine off and when you just want to put it in park.
Perhaps this is what's happening. I will experiment by stopping in my parking spot and see if it shuts off before I put it in Park (though it shouldn't if I'm in Race.) If so, it's the driving stop/start function. If it stays on but goes off when moving to Park, that's different.The car believes that you've stopped for a light and has activated start/stop.
Yes, this is part of the confusion here. I drive from work to home with only the radio on so should not be drawing too many amps (partly why I asked in the other thread about a voltmeter) and the regular driving around start/stop should work normally. All the criteria in the manual are being met as far as I can tell and the only one I can't check while driving is the battery voltage (no voltmeter readout!)Try parking with no accessories on such as your ac. The start stop feature on your car works with a lot variables to make sure you are not drawing too many amps for the feature to work.
I expect a car to work *normally* and not do one thing one day and another thing the next day when I didn't do anything different. In my case, different days bring different outcomes which is not how a car should normally work.
In reality, there probably is a scenario where - if in stop/start - the car has figured that you actually want to shut down (opening the door?) and actually turns the car off but I'm not sure that I'd trust that.

You're OK with a car doing something different with identical criteria but I'm not. Two identical trips with two different outcomes is not EXACTLY how a car should work and I'd like to understand the reasons it's doing this. Apparently the car is very specific about one or more of the criteria and it's not something obvious which is determining what's going on.But that's EXACTLY how start/stop works on a car with a normal 12v battery under the hood. And that was my ENTIRE point on RTFM: you were looking at putting the car into park and getting out of the car and somehow it divines that you're leaving the car. We were pointing out that it's no doubt somewhere else in TFM, part of the start/stop mechanism--and the manual should explain, in great detail, how the start/stop mechanism works, including the conditions under which it won't work.

The manual does describe some of this but not in as great a detail as you think; there are only two sections I can find that address start/stop and not one of them says anything about the engine shutting off when moving to Park. As far as I can tell, it should not turn off when moving to Park.
This is not what's happening here in sunny Southern California - I assure you my two reference trips were identical. One was not sunny and the other freezing.One trip at below freezing temps and another trip at the height of summer--those are not "identical" trips no matter how hard you want them to be.
Pretty much what I've been saying but I want to know why so *I* can adapt to it and make the car do what *I* want it to. Yes, if this is scattershot and esoteric functionality, shame on VW for not being more precise in the manual. I shouldn't have to try to understand it. It should just work and work consistently.Nonetheless, it is what's happening.
So earlier you kind of called me out for appearing to expect the car to divine what I wanted which you indicated was somewhat foolhardy on my part but here you are using that very idea to explain what the car is doing! So if we pretend for a second the car is not doing that but rather following a logic diagram of cause and effect, I'm basically trying to discern the causes that arrive at an effect and KNOW what to expect. Sadly the manual does not do a good job of providing that information and, based on my reading of it, the car does not do what I expect in spite of the manual's verbiage.But frankly, I can easily see the system shutting the engine down when you put it into Park. If the 12v battery is fully charged and the climate control system doesn't need to run much if at all, then your putting it into Park is a clear signal that We Will Be Here For Awhile.
I just got out of a C6 Corvette that did not shut off completely unless you put it in Reverse. Otherwise the system remained charged until the battery was depleted. I'm well aware of this paradigm.The system is not the engine. That's old school. Old school was different....
Not correct. I'm an aerospace engineer and well aware of how all forms of technology work. But thanks for assuming I'm unable to adapt to new technology.I think the technology has surpassed your willingness to accept it.
That's only part of the equation here. One - the car sometimes shuts the engine off when shifting into Park and other times not when I can see no valid reason that should happen at all. Two - the start/stop function sometimes works and sometimes does not even though the conditions are the same in each trip (again, not sunny/freezing.) And I never suggested the car was ever completely off and I could simply walk away from it without pressing the Start/Stop button. The original premise was "Hey, the engine shut off when shifting into Park but now does not. How do I do that again?" but now it happens or doesn't happen and there's no clear reason why. Why my frustration at that seems to annoy you I do not understand.Engine off does not mean system off. Does not mean that you can get out of the car and go inside. You, the pilot, must *actively* turn the system Off.
I have not yet looked at any VW videos but will. At some point I'll have to bring it in and ask though I don't have high hopes anyone at a dealer or dealer service center will know any more than anyone else given how lame most dealers are these days.Have you looked at the relevant section of the Know Your VW web site? They have a video. I know, it's more RTFM. So be it.
Plus, were I you, I'd be bugging my dealer service department for any documentation *they* have on all of this.

Yeah, I'll have to try this. Thanks. Seems the electronics are pretty convoluted in certain circumstances and there's no full logic tree or table to follow to set it all up with the right outcome. Have to figure it out on your own. I'll see if setting it this way makes this function return.
Mine does it randomly in the garage, at the parking lot at work, on the driveway at home, etc. and sometimes it doesn't! No real rhyme or reason which is why it's so frustrating. But thanks for the data points.My car did the same thing a few times. It only shuts off when i put it in park if my front sensors are going off i.e. in my garage and the car senses the garbage bags close to the bumper. This is the only time it shuts when I put it in park.
Ouch. I'm so humiliated. Thank you for putting me in my place.Perhaps your car is too complicated for you? May I suggest this?
And I never suggested the car was ever completely off and I could simply walk away from it without pressing the Start/Stop button.
So the first week I have had my 2018 R it was set right - stop the car, put it in Park and the engine shuts off. I get out, lock it and go about my day. Today, after driving around with the wife for a while, it no longer does that and I must press the Start/Stop button to turn off the engine.
Ouch. I'm so humiliated. Thank you for putting me in my place.
Too bad there are forum rules otherwise my First Amendment rights would not currently be infringed.
It's both. The car is not being consistent. I'm attempting to get to the bottom of it. So it's OK for the car to be inconsistent but I can't?No? From your very first post that started this thread: So which is it?
Snarky replies like yours don't help. Instead of berating the person who is simply asking questions and trying to have a positive discussion, maybe your replies should be a bit more helpful. Instead your only two replies implied I was cheap and stupid. So forum rules require I be civil and can't appropriately reply. Suffice it to say, if you don't have any helpful solutions perhaps you should be the one moving along.Not following. You wrote whatever you wanted. So did everyone else. Am I missing something, or are your rights more than anyone else's? It's not like anyone called you something nasty. If your feelings are that easily hurt, this is not the forum for you.
