Just one....Dinan tune at an authorized dealer/shop has full warranty backing that matches that of the BMW Warranty.

It's technically a Dinan warranty that replaces the BMW Warranty in full remaining terms. Basically Dinan is on the hook for anything that breaks related to the tune. It's officially/unofficially endorsed by BMW.
