You're positive that dinan software doesn't void the warranty right?
Personally, I'd check with BMW. Voiding your warranty isn't worth it. While I'm sure folks are trying to help here, saying that "anything from Dinan won't void your warranty" may not be a 100% correct statement.
"The installation of Dinan Performance Products and systems may affect the vehicle manufacturer’s new car limited warranty. The vehicle manufacturer’s new car limited warranty may not apply to modifications to a vehicle or the installation of any performance accessories or components attached to the vehicle which substantially alter the original engineering and/or operating specifications or which result in damage to other original vehicle manufacturer’s components."
However, Steve Dinan in a Eurotuner interview said: "What came out of that was an agreement to warranty our products for the same term as the BMW warranty: four years/50,000 miles. We self-warrant; we don’t have an outside insurance company. If a Dinan product causes a BMW component to fail, we’ll pay for that, too. Then BMW covers what we don’t affect. You bring your car into a Dinan-authorized dealer, either Dinan or BMW gets the repair bill, and you get your keys back at the end of the day and drive off."
I don't know if they have a similar arrangement for CPO warranties, but it does mean that YOU MUST have a Dinan dealer do any warranty work (many BMW dealers are "Dinan-ed"). You get to fight with two companies over your warranty. Sounds fun!
Be very careful. Go to the source, not a collection of people eager to mod their cars. Repairs can be incredibly expensive.
