  1. Take a look at Porsche service campaign #W738 for reprogramming of the DME. What I read from it is that the manufacturing tolerances for the oil pressure spray jets in the block used for piston cooling were broad enough that the instrument cluster could sense a low pressure condition very intermittently. Since this is a continuous monitor it could set a fault anytime oil pressure drops out of specs pre-programmed into the instrument cluster. This is not necessarily going to last long enough to cause a dangerous situation. The fix, according to the bulletin is a reflash of the DME via PIWIS. What they will tell you at the dealer or your service guy that this doesn't apply to your car. What they DON'T tell you and they probably don't recognize, is that if the car has EVER been reflashed it could have the same software as cars covered by the bulletin. I don't have a copy of this bulletin that I can fax or e-mail to you but it may be available elsewhere on this site. HTH, Craig
