Low oil level light twice in one journey

[Corzo54]

Hi all just had my oil level light come on after and hour drive and when I checked it was low so I filled it up straight away to the half way mark. On my way home about half an hour later it came on again and when I checked it was still at the same level any ideas? Thanks

Might just be a faulty oil level sensor unit, now keep an eye on your oil level and if it "warns" again for no good reason, consider replacing the oil level sensor module in the sump.

Edit:- oil level sensor failure is not unknown on VW Group cars.
