On the vin # it says it was build 5/2010 ? am a bit confuse. Thanks for the clarifications.
If your car was built in May 2010, then it's almost certainley a N55 engine, as production of the N55 engined 135i started from April 2010 onwards.
If it looks exactly like this under the hood (bonnet) then it's a N55
