Motronic Control Units MED 9.1
The new DME control unit MED 9.1 from Bosch has been specially
adapted to suit direct fuel injection and the modified engine
specifications of the V6 DFI engine. It can be programmed with the
country-specific data records of the Cayenne V6.
Cylinder Head
The design of the direct fuel injection system, with two separate high

3, 5) and -2- (for cylinders 2, 4, 6) as well as the high pressure pump
-3-, has made it necessary to redesign the cylinder head.
