Oil sensor light - 2.0tdi 2012

[Bramley]

Hi Guys

Today my oil sensor light came on, on my 2.0tdi 170 Quattro a3.
It’s just had a full service a week ago. Oil level is fine.
Any ideas what the issue could be?

Gone in this morning and taken a picture myself (Mrs took first). Is it as self explanatory as this?
