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.

Suggestion

Is there a check procedure to further isolate/narrow down the root cause?

Leading evidence: 'Check procedure' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check procedure' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Considering the fault code ,If the relative position is out of alignment by more than 1 tooth, the fault code will occur .I think the camshaft timing error would be possible,but first you need to exclude solenoid valve.then checking timing chain/chains orbit

Suggestion

From what I've read in this forum the solenoid valve seems to be the most common cause of the issue and the cheapest to repair of all.

After resetting the fault memory, it takes a few trips and the error is back again.

However, I don't feel anything at all; neither an irregular engine run, loss of performance nor suspicious noises.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

My 987.2 S is currently giving me a bit of a headache. PIWIS returns the fault code P0018. After resetting the fault memory, it takes a few trips and the error is back again. However, I don't feel anything at all; neither an irregular engine run, loss of performance nor suspicious noises. I have attached the first page of the error report. How would you proceed? Is there a check procedure to further isolate/narrow down the root cause? Just taking it to Porsche for troubleshooting and repair is not something I want to do. I have AllDataDIY, a lift, tools and time. From what I've read in this forum the solenoid valve seems to be the most common cause of the issue and the cheapest to repair of all. Which part# would I need to buy? What is your opinion?
