I’ve been throwing PDK errors first thing in the morning with a cold engine that I think it’s attributed to low battery even though I did replace it probably two years ago. The car has sat a few times once for a month without a trickle charger. Anyway, I’m thinking that if registration/coding is required, and I didn’t do it then that could be the culprit. Can anybody confirm and if so, is it possible to register a two year old battery or do I need to start a new?

thanks in advance!

Maybe others can add more knowledge here, but I don't think that there is a "battery code" to be uploaded for 997s. I think is an electrical glitch related to the battery. I suggest to use a CTEK trickle charger with diagnostic feature, and it will either recondition the battery or tell you if something is wrong with it. That should be the first approach.

None for 997s. I remember my old e92 I had to do it.
