Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I keep getting this when reading out with durametric... my pdk shifts just fine though and i added additional oil to it until it was full like it was suggested here for better temp control (i had this error read out before the additional oil, too) i seem to get this error no matter the temps and how hard or not the car is driven the car itself is not giving any error only when reading with dura as maintenance every so often I stumble across this PDK C418 error and i find this reoccuring code does anyone have a clue? or does anybody know the definition to this error code? thank you!

Are you sure the error code is not stale? I do not know about the PDK but with the DME if the MIL (malfunction indictor lamp) status is 0 (off) then any DTC read is stale and not real. Your local Porsche dealer tech might share with your what the code means how it comes about. I'm a bit bothered by your adding oil to the PDK though. These are generally semi-sealed units and if they need oil they have a leak and that needs to be addressed.

POST 3Original post

my dealer is not giving me any info --- they just do do this here in germany at porsche you are quite alone in your issues if you are outside a stock car setup when I meant I added oil I did this: my PDK is perfectly tight and not leaking anything so you mean this error code may be just a communication error not necessarily a real error?

POST 4Original post

It could actually by a communication error. But I dont know enough to say for sure. It happened to me several times that I see strange errors, and the guys at the dealer just tell me that sometimes sensors send erroneous signals, and these should not be a concern unless they keep recurring and/or cause a CEL! Really strange having this sort of treatment in Porsche's home country though!

I am having the same C418 code come up and C401 also. I drained the PDK oil, changed the filter, added the exact same amount of oil back to the trans. It's also showing a P0010 code. Runs ok, just shifts around 2500 unless I'm really hard on the throttle.
