Oil level Error S60 2019 T8

[Guinness2108]

Hello,

I have issue with oil level, car always show maximum (although this is not so, I poured 5 liters in place of 5.6 to check)
When I try to check level in mm, i see next error:

I tried to wash the sensor, it didn't help. There is no error related to the sensor, will replacing it help? Does anyone buy a sensor from aliexpress?

Regards

From my personal experience, never buy cheap chinese sensors for any car unless you definitely know it's the OEM manufacturer you are buying from. 
In some cases, used sensor from a low milage totaled car are even better than the chinese new ones.
