Hello.I have a problem with my Seat leon mk1 1.8t Topsport AUQ. Started last week i was driving and the Oil level came up with one beep.Color is Amber,runs sounds normal no leaks whatsoever,oil is full on dipstick.Its a very looked after car.Where should i start looking? If i open and close the bonnet it disappers,even when the car is running.Is it the sensor on the bottom? Thank you in advance
