The RMS is just a simple little oil seepage - no need to worry, I agree its a design fault and in reality Porsche should pay as its a design fault, guess no one has legally challenged them yet so they will keep on avoiding responsibility.
Dont take the word though of the garage (indy or OPC) often the RMS has leaked and it gets changed, however, very few Indies or OPCs actually clean the oil swarf of the bottom of the gearbox bellhousing so on a future date they see the swarf and report (to be on the safe side) that the RMS is seeping.
First hand experience of this, RMS changed 12000 miles ago, took car to Autobahn Coventry for major service - they reported a seepage of the RMS, had a look when i got home and cleaned off the swarf and since then done another 4000 miles - not a hint of oil in the area. In fairness they didnt do the RMS - that was Porsche Reading, and it was only right to report what they discovered.
(Reading does not, in my opinion, provide a good service)
Of course the seepage could develop but apart from the annoance of the odd oil spot on the driveway its not likely to cause any problems, and by the time it does the clutch will have failed, the airbag spring unit, the MAF, the brake disks, the headlight switch, the remote locking key, the 2nd gear syncromesh and the IMS will be waiting for everything to be repaired then let go.
The joys of Porsche ownership
