AWD controller oil change?


Recommended Posts

Hoping someone can confirm.  From what I can gather, the 996 AWD controller is a sealed unit and doesn't require an oil change. There's no service item listed in the service schedule.  The 997 requires a change every 12years or 120k miles but seems the 996 does not.

 

Can someone confirm. Thanks

At 90,000 miles Porsche recommend to replace the front differential oil. But the all wheel drive on 996 turbo got no controller as such. It is a viscous coupling. Viscous clutch on the parts catalog item#6. This viscous coupling is sealed and no maintenance is required....

Yeah. Porsche seem to call it a "Controller," which suggests it's jammed with electronics, rather than a bunch of plates and oil.
What's strange is I'd expect the same unit to be in the 997 but the 997 does call for an oil change. Must be a different unit

Good news for me though

Thanks
