So I drive a 2013 F30 328i. When my car starts (ASS) the whole car actually shakes, and I have had multiple passengers, including passengers sitting in the back seat say "is your engine starting again everytime you stop? because i can feel it, its really rough"

This is from people who don't even care about cars which I believe says a lot.

Anyways, my car is now in the dealership to get the ASS recode and some other small issues looked at, and I have a loaner 2014 328i Gran Tourismo.

Has anyone here who has rough ASS tried a 2014 F30? This car (2014 328i GT) is rediculously smoother. I am afraid that the 2012 and 2013 F30's got the previous revision, and the newer revision to the ASS, released on the 2014 models, (unless this is specific to the Gran Tourismo, although I am guessing this is not the case) is a lot better.

I am going to test drive some other cars from the nearby bmw dealership to see how their ass feels compared to my 2013's ASS.

The 2014 328i Gran Tourismo is so much smoother, I had someone who doesn't care or know anything about cars (my mom) drive it, and she couldn't tell the engine was turning on and off.

I wish I could get my 2013 328's ASS to be like this car's ASS.

The ASS in my 2015 335 M sport is very smooth, ASS is so much better with a manual tranny because you can control when it comes on or off by letting out the clutch with the stick in neutral. I had a 2013 auto 328 as a loan and the ASS was very rough..

ASS absolutely sucks, minimal fuel saving with added complexity to an already complex system...not to mention working the starter and battery to death. I would disable it permanently if I had it in my car.

I must say I don't find it a problem in my 320. It's smooth, minor shudder with AC as mentioned but had no stalls and it's fast enough 99% of the time to allow me to do my thing in traffic.

As for its actual usefulness I don't know, but I would rather do something about Eco pro which remaps your accelerator pedal from normal or irritating.

What year is your 320i? I suspect 2014 and on have improved ASS as opposed to 2012 and 2013 F30's...

I used to hate it but I think that was mainly because I wasn't used to it. It took me a few months to get used to it now I barely notice it.

Is anyone else worried that the starting and stopping is harder on the motor than letting it idle?

I turned ASS off I'm not being too hard on the motor during break in.
