I just recently purchased this car and i was aware it had a few issues and with time i fixed them. but i keep receiving this message none stop to reduce oil level, I had the oil changed and set to factory level which i believe is 7.5 l or something my mechanic knew so he measured accordingly even after i left the shop 5 mins down the road the message appears none stop what can it be?

 

In the so-called dyno mode you can read the actual oil level in liters, along with the actual battery voltage. (turn key on, tap odo reset button three times. MFD will show Ub 12.4. Use steering wheel buttons to move through the menus) If the reading is too high, you need to remove oil. If it is OK by workshop dipstick, the sensor has gone over the rainbow if the dyno mode reading is higher than the dipstick.

It is never a good idea to roll with too much oil in the engine.
