Bought a used 2003 Z4 with DINAN 'kit' on it. I know the air box and exhaust are DINAN. What else was done to the car to turn it into a DINAN? Arrowhead BMW told me that BMW corporate required dealers to 'detune" the engine back to OEM specs. Does anyone know if this is true?
On the older Dinan vehicles they would but stickers of the upgrades under the hood to show the carb numbers off. I know BMW and Dinan have split ways since BMW started pushing upgrades. In order to CPO a car yes we have to remove all aftermarket parts or software. Being that it is a 2003 I doubt that has been done.
