rotor repair on 2005 Porsche Cayenne

Can the rotors on the Porsche Cayenne be machine and repaired. My Dealer said they can not. Is that true?

Asked by for the 2005 Porsche Cayenne
They can be machined but their experience and my experience on some other cars may indicate that the rotors only warp again in short time and therefore may warrant changing them at this time. Call several other Porsche dealers see what they suggest.

I would replace them like your dealer advises-it will last longer then turning them and the parts don't cost a whole lot.
