Point 3) Here is the translation from Autobild: "After all these improvements current 335i accelerate again nearly without turbo lag. Autobild has convinced itself of that fact with measuring trips and on the dyno. The Reason: Because of the improved wastegate hardware, the software of the engine control unit can regulate less restrictive.". In the U.S. statement, BMW says that "X6, 135i, and 3 Series/5 Series vehicles from March 2008 production onward are not affected."
Note the word "nearly" in the Autobild article. I understand your doubts about MSD81 cars. Never having driven one of these myself, from what I've read here, my feeling is that those are like MSD80 cars with v31.1.1., namely " less restrictive". Or as Shiv put it: "Maybe not as responsive but very close.". |
Many thanks for your helpful comments. I've been advised before that 31.1.1 should be better that the 30.0.2 that I have and you are further confirming this. Before trying again to get an update I might as well wait until v32 now. The problem will be that I'll be back to the car needing to throw a code for it to be updated. Unless BMW go all soft on us, maybe they'll say one thing in public but be more helpful in reality, hmmm I won't hold my breath.
