Hi all,

This question might sound a bit strange, but I am not entirely sure which N52 variant is in my car.
I drive an '07 E92 330I automatic. When I bought the car, I didn't know a lot about these 3 litre petrol engines but I was pretty sure that I have the N53 engine mostly because the car has 272 HP and the engine cover is black. I don't know if this is a general rule, but I've noticed that most N52 engines have a gray cover. Also a friend of mine drives an E90 330i and his cover is also gray.
After a closer inspection, I've noticed that my engine is an N52B30A according to what's written on the side of the body pillar. If I search my VIN on realOEM the engine that comes up is N52N..and on the paperwork that I got back from BMW from when I had it serviced sometime ago, the engine code that is specified is N52K.
I was also surprised when I tried to clean my MAF sensor because I found out that I actually don't have a MAF sensor. Instead..I only have a small temperature sensor.
Also, according to Wikipedia e92 is not on the N52 200kW applications list.

Since I can't find anything on the internet..does anybody know what's the difference between this N52B30A engine and the N52B30?
