AmarB Posted May 2, 2011 Report Share Posted May 2, 2011 I understand it was changed over around October/November 2003. My car has a build of Nov 03, I'm hoping it makes mine a Euro four as I hear these had more reliable turbos? Any way I can find out which engine I have?

momo Posted May 3, 2011 Report Share Posted May 3, 2011 Not sure.. I always thought the Euro4 was an emissions regulation which manufacturers had to build their engines towards. i.e: if Euro4 was due to come in sometime in 2004 then most manufacturers will build engines to meet the specifications of Euro4 in 2002-2003.. I think this might be a question for BMW themselves tbh.. Link to comment Share on other sites More sharing options...
Rob- Posted May 3, 2011 Report Share Posted May 3, 2011 (edited) Look under the inlet manifold, if it has the swirl flap actuator it's euro4. The majority of the M47n engines were euro4 AFAIK. If you have a 136bhp M47 engine then it's euro3, and yes the turbos themselves were more robust. Edited May 3, 2011 by ROB1986 Link to comment Share on other sites More sharing options...
