Hey guys, I recently acquired a '99 Z3 Coupe and the previous owner says that its been swapped with a M54B30 (out of a 330i).
I took a look at the DME and its running the MS42 and while I know that's possible...is there a way for me to verify that from looking under the hood?
Im kinda new to M series of engines so thank you in advance for any help!
