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. I think the smell could have a long-term negative effect on my health and I think BMW must resolve this issue. I just can't believe no one else has this problem. To me it looks as if there was a leak in the exhaust system and the gas enters the cabin.

I would formally like to report a major safety concern I have regarding my new 2011 BMW 335is convertible. From a standstill without modifying any of the default configurations on the car, flooring the gas pedal, the car lurches forward (as expected) and then power completely cuts out for a second and then will continue on its way. My guess is the dsc is kicking in causing power to be reduced and then re-established. My concern is that a brand new car should be able to be floored without this happening. I recently had this exact situation occur as I was pulling out into traffic and very narrowly missed getting pummeled by another car when power was cut to my car. I have taken my car to my BMW service station and although they agree that the car should not do this?they at the same time say the car is operating normally. Their advice was to turn off dsc in a situation I want to floor it. This is my 3rd BMW 3 series convertible and I have never experienced this. Also, I do not think the driver should be forced to consider this before pulling out in traffic. And, if I were to lend my car to a family member, how would they know.
