Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Could well be the battery if it’s not been replaced (it will have a date on it somewhere) and the it’s not on a maintainer or the car is being driven infrequently.

Then, this weekend I've started getting stop/start failure error messages on the dash, again seems to reset after a restart and it also seems to impact the cruise control (standard, not active) and the function just seems to vanish.

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.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Morning all, I have a 992.1 that I purchased about 6 months ago, it's a 19 plate car. It's C2S. I've had a few issues recently, but before I book in with the dealer to have a look I wanted to get the thoughts of the PH collective. It seemed to start with PCM issues, a couple of times it's been working fine, then I get a completely blank screen, sometimes with music still playing and other times it looks like it goes through a power cycle and I get the Porsche logo as it restarts...I've had some instances where it just stays blank, even if I hold the power button down for a reset, but it does seem to come back to life after the car has been closed and locked for a period of time. Then, this weekend I've started getting stop/start failure error messages on the dash, again seems to reset after a restart and it also seems to impact the cruise control (standard, not active) and the function just seems to vanish. I am suspecting that it maybe the battery and I was thinking of trying a repair cycle using a ctek charger. Does it sound like battery issues? Anyone had any luck using a ctek to reslove issues like that? Thanks!

Could well be the battery if it’s not been replaced (it will have a date on it somewhere) and the it’s not on a maintainer or the car is being driven infrequently. The PCM issues could be related or a symptom of hard drive failure which is also fairly common at the age of your car. If it’s not failed completely you can clone the drive and replace with a solid state one fairly cheaply.
