Half engine light help
Hey guys, I currently have an n55 with jb4 stage 2 catless dps and exaust. Ive had a half check engine light on and off for a while now and want to take it in to dealership. What do I have to do before I take it to BMW? So I don't have any problems with them? Sorry... I'm new to this

Then if you still can't figure it out, take the tune off and drive around for a bit to see if the same symptoms occur... If so then you'd have to de-mod everything for the dealer visit or else they will blame everything on the DP and you'll get nowhere. |
