After reading this back-n-forth the past few days, I have to say I'm with DallasBoosted on this one. He is being told to "loose [sic] the attitude," when he hasn't had one and is being called a liar and a troll and told to "read the manual."
I don't see why that's necessary when he has been detailed about his limp modes and what has helped him fix them. All of that is anecdotal and is perfectly reasonable to post in order to refute the position that tracking the 335i is impossible. Could he be wrong? Sure, but that wouldn't make him a liar nor a troll. If the goal of this thread is to figure out what causes limp modes in an effort to help correct them (like the OP states), then his information should be welcomed.
