E92 N55 pwg to ewg?
Hello friends,
I have a question, i will try to keep a long story short. I have spun a bearing in my n55. My car is an e92 n55 pwg with the dct. I wanted to rebuild the engine but i decided to buy a brand new engine. The problem here is i got everything with the engine, like turbos, injectors hpfp and the engine is for a x5. So i will need to change some things with my old engine. Since i got everything new on the new engine i am considering to find out if it is possible to change it to ewg instead of pwg. Is this something what can be done? What would i need? The engine is complete so engine wise i dont need anything i think. Only thing i can think of would be a ECU. I would appreciate some help/info on this. Thanks |

The ECU you'll need is MEVD172G. It'll look identical to MEVD172, but its internals differ. You'll need an engine wiring harness that has a connector for EWG if your engine does not come with it already. Those are from 2014+ N55s I think.
Other than that I'm pretty sure it's all the same. The big thing that I don't know of is does any firmware for MEVD172G work at all with the E90? |

Worst case, I can imagine it would be possible to swap out the EWG with a PWG and have it still work fine unless there are physical differences preventing that conversion. I'm just speculating based on my own readings of ECU and engine versions I've done over the years. I find the stuff fascinating, but I haven't done anything like it myself on my own car. I've been wanting to grab an ECU from a junkyard to try fiddling with it. |
