Hello I have a 2009 model xc90 D5 , We just bought the car couple weeks ago.
And we had the oil change after that on the second day yellow light pop up and shows error.
Car menu is french
( GESTION MOTEUR REPAR DEMANDEE ) no icon on the screen, it just shows up on the computer as a new message
computer error code is ( 5660 capteur de niveau d'huile )
It gives this error code and I think the oil sensor is broken but in some forums I have heard that the sensor gives a warning due to excess oil and when it is emptied by 0.5 liter the problem has been rectified.
Is there anyone here who encounter the same problem or can give an idea,
( The person who changed the oil said they put 7 liters ( but everywhere says 6.2 ) and when I look at it, the oil looks like normal level. under maximum )
Regards( we deleted the error code but the next day it came back )

 

We got some oil back.We reset system for error code and problem solved ! 70 75% oil is enough, no need to be max and above.
