A new, pre-programmed DME arrived at my dealership Friday and was swapped into my car.
Leading evidence: 'Replace into my car' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace into my car' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt.

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.

Sorry for the double post .... should have been P1266 not 1226
Has anyone ever had a code of P1266. I know what the code means but I need help in finding out how to fix the car. The car is a 1999 C4 I got a CEL and loss of power at elevation. If I stop and restart the car it drives just fine. Also at lower elevation the car runs great. Could this be a simple MAF fix? Has anyone else ran into this problem? The road to and from the house is a dirt road.
The car is not mine and I am posting on here to help out an older guy .... He is in his 80's! He use to have a 356 that he pick up from the factory back in the day (1961). How cool is that!
Any help would be grateful.
thanks!
Looked like reflash of the DME to correct an altitude glitch.
"Cross Post from RennTech:
I just heard from my dealer who just heard from the regional PCNA tech rep.
He says that PAG/Germany is aware of the DME/OBDII P1266 Fault and failure mode. Further they know what is causing it and how to fix it in the DME software. A fix is in the works. "
"Cross Post from RennTech:
Porsche has made a change to some code in the DMEs of my car and the other car of which I am aware that have had this particular fault code, P1266. A new, pre-programmed DME arrived at my dealership Friday and was swapped into my car. PAG intends to incorporate the fix into the next release of GT3 DME code distributed by CD to those with PST2 subscriptions. When that code is installed in my dealer's PST2, PCNA has asked that my original DME be re-installed in my car and the updated code re-flashed into the original from the PST2. That way, all my engine history data in my original DME will stay with the car. Thanks to PAG and PCNA for addressing this."
