“I bought this 2011 Bmw 335d used in april of 2014 with only 18,500 miles on it. This car runs on diesel. As soon as I started driving the car on the daily basis I noticed a smell of sulfur or exhaust inside the cabin. Every time I drive the car and especially when I accelerate I can smell it with the windows closed. It never goes away and is very distinctive in its nature. I took the car to the dealership and they found and fixed some oil leak but it did not resolve the issue with the smell. …”
