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 :)
 
Heres a picture too

most likely the oil level sensor on the bottom of the sump, easy change over, you can either drop all the oil into a clean pan and reuse if its decent oil or just call it a part service and change the oil along with the sensor, or you could try the vacuum on the oil cap to keep the oil in while you change the sensor (i havent done this so not recommending but ive seen it countless times on youtube)

Thank you,its almost due to service anyway,do you have any aftermarket recommendation(i heard some sensors are quick to give up)or should i try to buy oem?
