Just an FYI, parts installed under warranty are only covered till the end of warranty not 2 years from install. Checking the tire circumference is a good idea. Also check the wheel speed sensors, the is a bulletin for replacing all sensors due to water intrusion. Sent from my Nexus 7 using Tapatalk
If the oil is in front of the wheel, you may have leaking convertible top cylinders. The oil goes out the water drain under the wheel liner.
pugs2bb replied to srfrdrew's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)Yes you should replace the seals on both flanges. I haven't needed to replace the pressure regulator flange. I have replaced several filter flanges and pumps. You intermittent starting problem could also be the purge valve sticking open but you would usually get a CEL.
Considering that the traction light flashes, check your tire sizes, not just on the sidewall but measure the circumference. If the difference is more than an inch, the abs may be reacting. The sound you describe could be the careen shaft also.
pugs2bb replied to srfrdrew's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)The drivers side fuel tank flange is most likely cracked, the white one. I have had a few tanks leaking at the plastic welded seams but that is rare. Is not a bad idea to at least put in the drivers side pump, it runs more often than the passenger side.
If the vacuum system is leaking that supplies the testing pump. The p0455 fault will always show up. Look at the brake booster lines for cracks and check the vacuum at the small line at the center of the firewall.
6.2013 is the map data for 2014 model year. We at the dealer usually get these updates about 6 months after they come out. You will most likely not see a change unless there are multiple new roads in your area and points of interest should be updated. The map version can be checked with the Porsche system tester at the dealer.
For most of your problems it sounds like the switch inside the door latch is going bad. Not sure about the headlight issue.
Your brake booster and o2 faults are most likely due to a cracked brake booster hose. Check the lines at all fittings and check valves for cracks.
This is very common if you have the outer door handle cable adjusted to tight. If you push the door in while unlocking and pulling the handle, it will usually open.
