BMW Dinan warranty

The Dinan mode does not cancel the BMW NA warranty. I had Danin S2 installed on my 335i at the Dinan shop immediately after I bought the car. Since than I had many warranty services done in my local BMW dealership, including updates of the Dinan software without any problems. Just the opposite, they give you a special attention.
