Read the fine print....i know it's not the same, but my dodge dealer sold Superchips programmers for their trucks....but the fine print said it is not backed by dodge and that warranty wouldnt cover issues incurred via it's use....bottom line is that your mfg warranty is at risk with any non mfg provided performance enhancer (dealers arent the mfg in this example)
...a common marketing ploy is that the tuner box is "undetectable" or "undetectable by the dealer"...read the fine print....sure, the hardware isnt detectable if removed, but tht ECM can log data outside stock parameters...codes can be cleared, but on some vehicles history cannot (no clue on bmw)....bottom line is if an injector goes south (example, assume not related to performance box) and it's going to be expensive to fix, if corp bmw investigates you can be more than screwed...they dont have to prove a box caused the issue, just that increased (above stock) fuel pressure was logged (example)....hmm, that's not a bmw issue if above stock parameters were used.
again, the odds are with you if you're doing mild power increase +40/+80 ish, or maybe more depening upon vehicle....but if you have a mfg defect in your trans, turbo, injectors or what not and it blows and they research and find alterations were present...they can screw you....bottom like is it's a risk no matter who's product is used....granted some companies may address this somewhat better than others.
It sucks, i really want a box for my x5d as i'm sure it will be wonderfull....but i cant afford the risk of a major issue being on my dime (esp on a lease)....
