Hi,
Greetings from Singapore, where the temperature is 25-35 degrees celsius all year round.
Background and issues
My car is a MY 2010 Punto Evo 1.4 8V Dualogic with 37000kms (23000miles) on the clock.
For the past weeks, I have been getting the following issues during overnight cold start, or after more than 6 hours of standing.
Engine oil is at the MAX level of the dipstick. This issue happens only in cold start. If the car is restarted in 10 minutes or 1 hour while the engine and oil is still hot, everything looks and sounds normal and the oil pressure warning light goes off in no more than 1 second. There are no weird or knocking sounds when driving or high revving when everything is in up to temperature.
What I have done
I have done the aforementioned items, and ensured the engine oil is at the correct level, but they did no change to the cold start oil pressure issue.
I have visited 2 different mechanics with fiatecuscan and examiner, which they claimed the oil pressure reads ok (when engine is hot).
I queried if it could be due to a worn oil pump, worn main bearings or big ends, and both mechanics thought it is unlikely, as my engine's mileage is too low to have caused significant wear to the oil pump and bearings, even if I had been doing extended drain intervals. However, they do not have an explanation for the low oil pressure or diesel sounding engine during cold start.
I don't know what I should do next, short of getting the mechanics to drop the oil pan or strip the engine to investigate. If this issue can't be solved, I will probably just leave it and drive it to a point I need a rebuild.
Hence, any suggestions or similar experience to share will be greatly appreciated.
Thank you.

- Oil pressure warning light takes 5 sec to go off during cold start?
- Message pops up saying "insuff. oil pressure stop & turn off engine"
- During which, the engine clatters and sounds like a diesel.
- Once the engine is fully warmed up after 10 minutes or so, the diesel sound disappears.

What I have done
- Done engine flush before oil change
- Replaced engine oil with fully synthetic 5W40 and new oil filter
- Replaced oil pressure switch
