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.

Suggestion
Mine is the same, seems to run close to 5 bar on all but idle.
Leading evidence: 'Run close' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Run close' (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.

Suggestion
Sounds like your idle and perhaps your running pressure might be a bit high compared to Porsche figs (which by the same token always seem a bit low)

Suggestion
The Idle pressure seems a little high (when warmed up), are you using a thicker grade oil?
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.

My C2 is a 2001, 36,000 miles and has 5 bar (max on the scale) oil pressure at cold idle. When it warms up to 90degC the oil pressure sits at about 3.5 at idle, but goes right back up to 5 bar when revving higher than 3krevs. The manual states a typical warmed-up engine pressure of 3.5bar at 5k revs, so if anything my oil pressure is too high!
What is the norm?
Thanks
No, Mobil 1 used in its first major service 18months ago. Its only done 6k miles since and not needed topping-up at all. I've had to top-up the coolant twice in about a year, probably about a litre in all, but the coolant is still a clear/pink colour.
I can feel yet another paranoid thread coming on, I must be the first owner to be concerned that my oil pressure is too high!
Mine on a rebuilt Autofarm engine (4000 miles) is 5 cold idle about 1.7 hot idle after a thrash and about 4-4.5 over 3000rpm. which I believe is about normal?
Sounds like your idle and perhaps your running pressure might be a bit high compared to Porsche figs (which by the same token always seem a bit low)
Its probably just an optimistic / faulty sender or guage.
But its better to know what the pressure really is so I would get the sender/guage checked in case its reading 3 when its 1 (unlikely)
When warm mine sits at 2.5bar on idle and goes up to 5 at 3k revs.
I have the X51 engine which apparently runs higher pressures.
Have you got any aftermarket bits on the oil lines / X51 oil pan etc?
No, nothing aftermarket at all. I can see that there is quite a range in engine pressures out there, so I will assume all is ok..........
Thanks again for the responses.

Am I the only one a bit concerned about the comment above re: coolant? Surely such topping up can only come from a leak in the coolant system? The whole system is about 25 litres so holds a lot of fluid, therefore it would still be a pink ish colour despite topping up with a litre or so. I'd be more worried about this - time to pop into your current Porsche experts!
