Technical Sudden error code

[spijkermenno]

Hi fellas, during a short drive today suddenly my MIL and hazard light came on (both yellow, not orange or red). i felt no problem with the car as it still had all the power, the temperature did not rise or anything.

When i got home i plugged MultiECU in and found this error code:
1. P1540-13 - Variable displacement engine oil pump

I have searched internet but i cannot find what this means. Do any of you know by chance?

Fiat Punto TwinAir 101hp 2012
around 160.000 kilometers on the odometer

I added the report from MECU to this message.
