Servus,


meinst du den Unterschied N14 zu N18?


hatte das mal vor langer Zeit in einem UK Forum gefunden, weiß aber leider nicht mehr wo.



Hatte mir nur mal den Text kopiert. Ggf. können ja das die Fachleute Bestätigen:


N14 Engine - N14B16AC (171hp / 177 ft-lbs)

• Infinitely variable single VANOS (intake only)
  
• Siemens DME MED17.2 engine management

N18 Engine - N18B16M0 (181hp / 191 ft-lbs)

• Infinitely variable double VANOS
  
• Map-controlled oil pump
  
• Variable valve timing (Valvetronic) with 3-phase servomotor and integrated eccentric shaft sensor
  
• Composite camshaft construction
  
• New piston design
  
• Siemens DME MEVD17.2.2

The PCV design is updated in the N18. Rather than an external hose on the passenger side, the vacuum line is internal to the valve cover. This is (presumably) intended to reduce propensity for effluents pooling in the intake manifold. The boost line between the valve cover and turbo intake pipe is also different but seems to be functionally equivalent.

The N18 added a cosmetic cover over the front of the valve cover.

The N18 adds a small heat shield over the turbo oil pipe to help mitigate any coking in the line.

The turbo intake pipe in the N18 is rigid, as opposed to the flexible pipe in the N14.

The noisemaker is eliminated in the N18.

The N18 intake airbox base is slightly different (the JCW intake won't fit because the mounting screws don't line up).

The N18 oil dipstick is different (and many would say a step backwards in usability)

The Sport Button adds "pop and burble" to the exhaust
