Loss of power, illusion or real.

Hello all. Shortly after I bought my 2013 335i, I went back to the dealer and disabled engine auto stop feature. It's the one that stops the engine at the traffic lights. Now the car remembers the last state of the feature. If it was OFF, it stays OFF after I start the car next time. Since the dealer reprogrammed that button, the car doesn't seem to accelerate as fast as it used to. Maybe this is an illusion or maybe it is not. Has anyone experienced a similar problem?

Not in the e9x series since we don't have auto start/stop. You may want to check with the F30 forum.

It is entirely possible that the dealer accidentally accidentally may have removed an M badge and that is the source of your problem. I hear those account for a 3-5 hp gain each.
