z4 stalling problems

[ymdd]

has anyone had this problem before ? its the first to hapen to me today. i was at a complete halt at a street light while getting ready to move it stalled, key in my pocket its battery is low which could have caused it that was my first assumption but then I read that this seems to happen a lot any ideas?

I've never stalled. BUT at times whenever I come to a slow rolling stop the car will shake a bit right before coming to a complete stop. Feels like it's going to stall. The second I take my foot off the brake it's fine. It's worse when making a sharp turn pulling into a parking spot.

I feel this has to do with the double clutch right?

I don't think so, because this hasn't happened in my car and i have the DCT....

It isn't normal to almost stall when coming to a stop regardless of what gearbox you have... unless it is a 3 pedal manual and there is user error

My car has a history of recurring issues. I reported similar issues:
1. After stopping at a stop light and ready to go, the vehicle hesitated to move
2. Another time, I stopped at a stop light and when ready to go, the vehicle didn't respond (I did hit the gas pedal :-))

When I took for service, they didn't find any faults. So they reset some adaptation values and cleared faults. They said no faults and also cleared faults. What are they I don't know. But I didn't notice these issues after that.

I don't have a DCT and it's certainly not normal. I'm dropping her off this weekend to get it checked out. Curious to hear what they have to say.

Interesting. It's worse in high temps and the A/C on. Which I pretty much everyday here in So Flo.

Same thing happened to me last month. Car stalled at the traffic light, most of the time, the rpm drops to 400 when it comes to near complete stop. Went to dealer, they updated the software, adjust to 100 rpm higher. Never stall again. But sometimes still have the rpm drop, not as low as before tho. not even near the stall point anymore.

Below were the errors before went into dealer:

See the recall notice concerning stalling just posts. Coincidence?

My car has had a rough idle and long crank at start up. No codes though. going into dealer on Saturday.

Thanks for the heads up on the recall

Rough idle is one of the reasons I dropped her off this morning. Also, every 10-15 starts my starter would make a loud grinding noise. Same sound a car makes if you ever double started one by accident. We'll see.

They didn't even get a chance to look at my car today. Still sitting at the shop. Gonna be a long weekend! I did I get a 2014 X1 28i for a loaner. Guess I'll have some fun with that while I have it.
