My car is on limp mode after manual swap

Isorole · 03-18-2026, 11:14 AM

I have a 2008 E90 325i. I did the manual swap, did the clutch switch wiring as per the manual. I did the coding too, like removing the $205 from cas VO, doing FA_Write and did the FA_write to NFRM. Then did the sg_coderein to CAS, NFRM, DSC, KOMBI, DME too. I don't why but my car is still in limp, it's not giving power as a manual.

Any help please?

You may need to flash the DME with manual software i think. What fault codes are you getting. e90yyc will know.

Assuming you did the wiring and coding correctly, nothing obvious springs to mind. To clarify, it cranks and starts?

Post the codes you’re getting because that will almost certainly highlight the issue.

NZE90 It’s been so long now that I can’t remember all the little details. But I don’t believe any flashing was required. Just a matter of default coding with updated VO
