Stop start feature
My A6 TDI is about 5 weeks old with 1000 miles. Since day one the “stop/start” feature has only worked intermittently. I have read the manual and understand that the "stop/start" feature does not work under all conditions. I am talking about it not working during times when it should- – normal residential street driving after the car has warmed up. For instance, today I had the car out on a 12 mile trip, 6 miles each way; residential area; weather in the high 70's; a/c on for the entire trip. I counted 13 FULL stops at red lights and stop signs. Not once did the "stop/start" feature work. (and yes, the feature is ON). Since I purchased the car, I have noticed that the "stop/start" feature works about 50% of the time. Today was a fat ZERO.
Now, I know the problem cannot be all me. I had the car in for service earlier this week (for this complaint and several minor issues) and was given an A6 3.0 as my loaner car. I counted 6 full red light and stop sign full stops and each time the stop start feature worked.
Audi service found nothing wrong with the "stop/start" feature during the service.
Any ideas???

Assuming the other criteria is met, i.e. a/c, engine temp, etc., Stop/Start will only engage if the brake pedal is firmly depressed. It will not engage if you come to a gradual stop w/o fully depressing the pedal afterward.

There are a number of parameters which are considered in the operation of start/stop function, and not limited to HVAC (call for heat, or cooling), charge level of the battery, ambient temperature, and temperature of the vehicle (oil/coolant). On my Q5, I enabled the battery level meter and was surprised to see that the charge level varied between 70 and 60% of full charge. Stop/start never worked when the charge was below 80%. The alternator of this car has some "smarts" and it is not constantly charging the battery, as far as I can tell.

Just being reported on today. They say it will be available late this summer in the US. And it is being reported as HAVING the LTE.
I was wondering if you thought there was any chance that was, in fact, true. And if it is, whether or not we may see that on our MY15's.

Snag, completely off topic, but did you see the new A7 facelift?

Working in downtown Los Angeles and facing traffic on a daily basis, I use the Auto Stop feature alot. I was also wondering about when it works and when it doesn't. I have noticed that when the AC is running, the Auto Stop feature does not always work even when depressing the brake pedal fully. This does not happen consistently, however.
On occasion, with the AC off, I notice my Auto Stop does not work. Not sure why, but this has happened maybe 2-3 times where the Auto Stop does not work for the whole trip. I use it the next day and it works fine.

Well, I agree. At least about the believing it when I see it, but I guess it is "official".
