Mein Auto: 2011 BMW 528i
Took my car to the dealer today. Went for a drive with the shop foreman in the service department. He said the slight lag I felt was "normal". The TSB everyone seems to be refering to in this thread is for the N55 engine, which I understand to be the turbo charged version. My 528i has the N52 engine, which is naturally aspirated. Apparently there is no TSB regarding it, at least that I am aware of. They offered to reflash the adaptive driving memory to start its process over again and said they would check the electronic specs for the throttle movement. As long as they are within their parameters, the tech said there was nothing else he could do.
He gave me the "drive by wire" speech and explained it would not respond like cable or linkage actuated mechanisms. I told him I have a Honda that is also "drive by wire", and the throttle response of that car is instant and consistent throughout its entire pedal travel, not at all like the laziness of the BMW. Again I was told that as long as the readings he got were within specs, there was nothing further he could do. I'm not real happy with that. This is my first experience with BMW and their service procedures, so I'm not sure where to go from here. I did compare it to a loaner 528i they gave me and the throttle response on that car was about the same......still lazy, but maybe a hair better from a dead stop. I guess their take will be since all our cars have the same problem, yours is "normal" and compares with any other new 528i on the lot.
Has anybody with a 528i on this board dealt with this issue? It seems most on this thread have the 535i. Any advice would be appreciated at this point.
