I was experiencing the same as many others where if you are at a complete stop and you go to accelerate the car doesn't respond right away and you naturally apply more gas and then the car jumps ahead of you. If you were to move to the D/S position, the car was perfect and you didn't experience any lag in acceleration... it was almost like the car was set to start off in 2nd gear vs 1st.
Don't know how to explain it....seems pedal has to be pressed more than it should before getting an immediate throttle response. Like a small dead spot, I suppose. Only in normal mode. No lag in sport mode. Response is immediate.
It has scared me a few times when pulling out from a stop sign into traffic, thinking you have plenty of time and ease onto the accelerator only to find yourself moving like a snail, then having to stomp on it to get moving as traffic nears.
It's not the engine's response I am worried about. It's the ability to drive smoothly. I cannot, and neither can my wife, get this car to pull away from either a dead stop or a slight rolling stop smoothly and with consistent speed, more than 20% of the time.
You have three options normally for takeoff in this car: you have to feather the throttle and creep away like a cat burglar; tromp on it and leave like Don Garlits; or use normal throttle input, have nothing happen for 2 seconds, and then feel like a garbage truck just rear ended you.
I have a 2009 528i w/ Sport Package. My 5th BMW. They gave me a loaner 2011 528i for my last service and I still can't get over how differently they drove. The 2011 felt bigger but not just that the throttle tip in was much more agressive and combined with the loose electric steering it was very disappointing.
If this car was being used for a limo service, the driver would have no repeat customers. If your kids take their driver's exam in this car, they'll fail. It really is that bad.
I noticed this with an F10 528 loaner. That throttle lag is not fun, especially if you need to get out of a situation.
It's not a delay which decreases a transient surge. It INCREASES the transient surge as the car does not respond to the throttle for a half second then bolts forward with an awkward lurch and a slam. It's much rougher than a normal takeoff would be. It's not at all smooth. Some have described it as being rear-ended.
For the sake of clear discussion, let's not call it lag. Let's call it a "lack of a linear response to the throttle pedal".
I can't figure for the life of me why BMW would design it this way intentionally. It just makes the car hard to drive smoothly from a standing start. It's stupid. It's not the end of the world but it is stupid.
I have demonstrated to my tech that I get a 2 second lag when stepping on it as I coast down to 20mph. He readily agreed that it was an issue. My approach is that it is a safety issue (which it seriously is) and I have been presenting it this way.
Edmunds Inside Line has noted the same issue with their long term 528 as well. Its not the turbo, its the throttle and transmission programming. Its not related to actual engine power at all.
