Hi, first I've noticed very intensive smell of raw fuel coming out of my exhaust, but not consistantly. After that the level of oil in my motor started to increase slowly. I've changed it several times and i can say that is building up about a liter on every 2000 miles. I've been told by the official service center that maybe the fuel injectors are leaking when the motor is off, but they couldn't tell me for sure. Since they wanted to charge me about 900$ and were not certain that could solve the problem I've decided to look for help elsewhere. I hope that I came to the right place. Thank you in advance
