I've read that before but I don't really understand how. If the piggyback has been removed, then they would have to see the car's log for max HP and torque right? But how can they prove that the car didn't make its own mistake and allow that boost? Seems like a lot of work for them considering that even if it was tuned, they would have to prove that the tune itself caused the malfunction.
Even so, this is a good reason why the extended warranty that's offered is a good idea. It actually is underwritten by a 3rd party and is only used if BMW denies the first claim. They don't have access to BMW's computers so they wouldn't be able to pull those logs. At least, this is what a BMW financing guy told me
