Low oil pressure warning.

[st-rider]

Hi. Just had an issue. Low pressure warning text and oil can icon. Recovered to garage (why does this stuff always happen late afternoon on a weekend?). Only thing is cannot find any obvious cause.

Car is b6 2l diesel from 2008.
Plugged in obd2 and no error codes.

Plenty of oil by dipstick. No leaks obvious. No build up of oil on undertray (so no leak). Guy did say maybe suspect inlet to turbo, whatever that could be.

So what might be causing this? Plus what might b ed a cure or help with diagnosis.

Thanks in anticipation.
