Hey all... I have an '04 325i E46 with an M56 SULEV motor. The radiator is leaking. Does anyone know an M54 radiator (Behr, Nissen) will fit my M56? Will it throw a code? I just hate to pay $400 for the BMW M56 spec rad. Thanks!
The super e46 does have a special ozone radiator with sensor in it. So yes if you do swap this out there will be a check engine light for the missing sensor.
