I always though my 530i MY2010 had a N53 but after researching a bit and looking through the VIN i found it actually has a N52N.
Also just in case how do i find out exactly what engine my car has?
According to Wikipedia (Which i know is not 100% right all the time)
http://en.wikipedia.org/wiki/BMW_N52
http://en.wikipedia.org/wiki/BMW_5_Series
The N52B30 was used in the E60 530i from 2007 - 2010 in a 268HP-272HP configuration.
Production date of my car was 2009-6 (June 2009) which was the last year E60's were produced and Model Year is 2010.
But what i really want to know is if this car has 255HP or 268HP?
Thanks.
