Hello dear forum … Thank you for the possibility of exchange here. I have the following problem and I am in despair shortly before. I have a Seat Arosa 1.0 / 127000 km down for about 4 weeks and if I drive longer time (over 30 min.) lights up the oil lamp, red with warning tone . Always for 5 sec. Then it goes out again. When I got the car, I immediately made an oil change. The car had previously 5W30 … I changed to 10 W40. Can the problem be because of it? .. . The oil consumption is currently very heavy … I always have to refill one litre after about 500 km. Is that normal? The car also does not lose any oil … so no stains on the ground … Where is the whole oil going? The workshop now wants to replace the oil pressure sensor , but can also not make sure that it is because! Does anyone have an identical or similar problem …? Can the car eat more oil if the oil pressure meter is defective? I thank you already for every answer and nice love greetings! Nina the following has already been done at the car… – Oil change – V-belts – Ignition coil
