Hi everyone. My girlfriend went to coventry and got my a3 t from a dealership about a month ago and when she started driving back, it started beeping at her with an oil can showing, so she went back to the dealership and they plugged it in to an obd, it was showing no codes, so she drove back. She said on the way back it only beeped at her when she was doing 20mph or less, other than that it was fine. Found out the other day what the oil can was telling me, it says to pull over and check the engine oil level, the oil level is full so do you think it's the sensor or summit more serious? Also it only starts beeping when the engine has warmed up.
