Hi I’m looking for answers? Re my 2.0 tfsi bul Quattro Se. I don’t understand this car at all for last 4 years oil light goes off every 3 months from full. Today the oil light went off December 2019. I last topped up May 2019. So the oils lasted 7 months even though I’ve done nothing different and driven the same distance of 8k a year. What annoys me even more after speaking with castrol customer service I was going to change in 2020 from my current 5w30 to 5w40 as they said 5w40 should last longer in my car. FYI I get the car serviced like clock work By Audi every year with no leaks, errors or issues etc, no expenses are spared on my car.
