I will be taking my car back Monday to either get the Android auto reinstalled or removed so my on board GPS will work. The Tech there seems to not no much about the Navigation systems and the software updates. I have only had the car a week and a half. If I don't get some resolution, I will get with GM direct.

I hope other owners don't have this issue, for it sucks.

Yeah the starting not after the first 2 seconds worried me at firs, even asked the dealer and they confirmed it was normal on this engine.

Keep in mind I still don't own a 6th gen but I have now test driven 3 SS's with less than 10 miles on the clock. I have noticed that all of them seemed to have a misfire at idle. None of them had noticable misfires while driving and the last one seemed to have smoothed out after my test drive.

Have any of you others noticed this?

I wonder if its simply the engine hasn't been given enough drive time for the long term fuel trims to calibrate to iron out all the adjustments of the short term fuel trims.

Maybe this is only an issue for an owner who picks up a freshly delivered car with around 10-20 miles on it. I would assume that the car smooths out after a few drives since I haven't heard anyone complain of misfires.

If they are misfiring it would throw a code immediately. Are you saying they are idling rough?

Yes the car would have a mild hiccup or kick in the idle. Very easily noticed as a misfire by anyone who has experience in the auto repair field. It would kick maybe 1-2 times every 10-15 seconds.

Unless things have changed since I worked at auto shops, misfire codes are usually triggered by exceeding a predetermined number of misfires in a certain time span. Even an excellent running car with have the occasional misfire. Thats why misfire counters are usually displayed in OBDII scan tools so you can monitor if a cylinder is close to triggering a code but just shy of exceeding the actual number needed for a code to be thrown.

Right I agree, but if it's happening that often at idle it would definitely throw a code. I believe (but not stating this as fact) the miss is from DI. My 328i and my 2.0T Jetta both use DI. And both I would notice a subtle miss about as often as you do at idle. If fact I believe there were several on the BMW forums who complained about it and were told it was normal. So I wouldn't be concerned. Maybe someone can chime in with knowledge on the cause.

Interesting. Definitely seemed odd to me, but it didn't affect the actually drive that I noticed just the occasional bump at idle.

Is there a way to cancel cruise control on the A8 without turning it off or using the brake pedal. Seems strange that there is no cancel button...

My 2SS does exactly what you mentioned, but thats only at cold startup. It stops being harsh after the engine is warmed up for me.

From someone that would know a misfire, my 17 is fine with just 750 miles.

Yeah, I've noticed a small miss every now and then. So normal or not?

I have the M6 but I can't imagine the A8 being different. On mine the cruise control cancel button is the one in the middle between the Resume button and the Set button. It has the big X label on it.

2SS and 2LT cars don't get a cancel button because the heated wheel button replaces it

If someone is making a comprehensive list of items, perhaps add the oil consumption of the V8?
