Yes, that is exactly what I am talking about - TURBO LAG.When I test drove the W166, one concern was a short list of complaints I had with the W164.
The major complaint was the time to get going from start as in a traffic light derby (of which I never participate of course). With the W164, I could time myself happily with the Pirrelli calendar. It was actually much faster off the line at half throttle than full throttle.
But on test with W166, I was quite pleased. The limiting factor was turbo lag (which the W164 never showed as it was not quick enough), but that was only for a brief moment until the turbo was on song.
The standing start is now acceptable to me, and the rolling pick up as always, is brilliant.
I had the original bucking problem and the 1st update seemed to fix it. Then, over time, it started to come back. They recently did an "new" update and that seems to have fixed it. I do notice that the throttle response when cold is very touchy. Meaning that just a little throttle gives it a big punch.Katiesdad,
Was that update done on the W164?
I had one done (by head office) and it fixed the problem, but introduced a bucky drive. Before I managed to take it back to get it undone, the trans relearnt itself and went back to the original way.
My local dealer never heard about that update.
The W166 test drives made me feel happy that the problem was solved.
