Powerchip remap voids warranty?

Hi, I have an E92 2008 M3 with a powerchip remap of the ECU.
Question is, when I go in to a BMW dealer for inspection i (or even just the 15,000 mile oil change) do they notice the remap?

If they do, does BMW void the warranty on the engine? Do they keep it on record so that even if you later brought the car back in for service and you remap to OEM settings, they'll know you have had the engine modified at one point?

Warranty is a big concern for me. Prestige BMW hates mods! (Even non BMW wheels, they'll shake their head at!)

as long as they didn't change the redline you should be fine. most dealers flash you back to stock with the latest ECU "fix" after any service. unless you report an issue with the engine they aren't going to hunt for a tune. I wouldn't worry about, just don't tell them.

any tune WILL void warranty. but as long as they dont find out, they wont know bout it and your warranty will stay intact. if you do have huge engine trouble, and they find something on your ecu that is not according to spec, they will blame your engine troubles on the tune and your warranty will be void.

If it happened to you, you'd be the first one. This question is asked on a fairly regular basis and the fact is, dealers up to this point can't tell if your ecu has been modified. It behaves just as a stock ecu should, just with more power

Also look up the magnusson moss act, the dealership can't void your warranty just because your car is modified, that's a common misconception.

Incorrect. Programming not done just because the dealership feels like it.

There are 4 parameters for programming a vehicle:
1. Part replacement (ex. replacing a nav drive requires programming to make it work)
2. Adding a part (ex. adding satellite radio to a car that didn't have it, requires programming to make it work)
3. PUMA authorization (techs are stuck on a problem.. and BMW authorizes programming)
4. Bulletin (programming is listed as a repair procedure or in conjunction with part replacement)

Routine services are not part of this list. Now, if you walk in and complain about bluetooth connectivity, and there is a bulletin or PUMA recommends programming, there is a chance the DME might get flashed. All of this depends on the current integration level.

100% Correct.

You don't get to pick and choose what components you program. If there is a new software version, it will program that control module automatically.
