OBDII Porsche specific fault code database request
Does anyone here have access to or have a list of the OBDII fault codes for the 996 Turbo? I have my own OBDII scanner, but the descriptions for the manufacturer specific codes ellude me (they start with P1,U1,B1, etc - as seen below in the chart). When I retrieved a P1114 code in my Turbo, I had specifics as to what it meant. It turns out that it was one of my main Oxygen sensors before the pre-cats. I had the correct code, but no database to reference it with. This site helps somewhat, but their database isn't complete: <a href="http://www.gendan.co.uk/diagnostic/dtcs.php" target="_blank">http://www.gendan.co.uk/diagnostic/dtcs.php</a>
Any help in getting the fault codes from Porsche would be greatly appreciated.
