Hi, I have done 74000 Kms in my Linea Diesel emotion pk 2010 and i am shocked to see black smoke in my car, engine oil level also went low (changed oil in 68000 Kms). I have checked with Marvel fiat in erode for diagnosing the problem, they said that there is an issue with oil seal in Turbo and you need to change the Turbo (cost around 45000). I am totally upset after hearing this. was the actual problem with Turbo? Pickup and engine performance seems normal.
