My understanding, from my BMW dealership and from Dinan, is that Dinan upgrades are covered under warranty. They will not void the BMW warranty and any "finger pointing" between the two will be handled directly between Dinan and BMW. I've also learned that some BMW dealerships are authorized Dinan dealerships (Flemington BMW NJ for example). I was also specificly told, that warranty work relating to Dinan parts may require the work to be done at a Dinan BMW dealership instead of a normal BMW dealership. Can anyone verify this?
