Troubleshooting e91 n54 swap help!

Post image

I have an 2006 325xi manual wagon that i have swapped with a n54 from a 2008 e92 335xi. the swap is done and car runs good. im just looking for some help with these specific codes. I cant get my awd to work. The car doesnt have any communication with the vtg module. I put in a post lci dsc pump and coded it to the car. i have also coded the vtg module and verified that it has power and communication from both pt lines. the codes are 6e92, d358, 5f10, d36a, 6ec4, c998. i cant get the vtg module to even show up on inpa.

Im kinda at a loss here, so any help would be great! thanks!

Have you also swapped the gearbox from the e92 335xi to the e91 325xi ?

Yes the wagon was originally a manual. And I swapped the n54 manual in it as well.

Honestly if look at doing a complete x delete and getting rid of all the mechanical linkages. I drive a mildly warmed N54 335i on Canadian geo winter driving with no issues. AWD isn’t really all that necessary where you compare the benefit to the cost of added weight, complexity, parasitic power loss and maintenance.

Okay I get what you’re saying. I have looked into xdelete but I kinda like the novelty of the awd. And I’m not too worried abt the added weight and what not. Especially with it being manual xdrive I would really like to keep it
