I bought BWM320 three years ago, I have droven it for approximately 110, 000 miles, the front indicator showed loss of Engine oil after 1, 000 miles, the local 4S station claims that it is due to the problem of Engines and the engines should be repaired, I wonder if it is quality problem from your engines, look forward to your reply!
