Hey guys, so I just got my baby detailed yesterday, due to salty interior from the long winter! Everything looks brand spankin new... Only a few problems. So I have a 2011 e92 n55 FBO, when I picked up my car, it was on and idling rough, in limp mode, pulled up a handful of codes on the spot. (27E8, 28B0, 28AB, 28A9, 2714) I cleared them, restarted her, and all was well. I also noticed it was in map 0 (I'm on ISO), considering they may have hit some steering wheel controls in the process, I figured its just trippin' out, threw her in map 2 and drove spiritedly on the way home, no problems. Also note that I did not get my engine bay cleaned (paranoid).

So today I start the car and am on my way to get a coffee, make a left turn, AWD malfunction and abs light and limp mode, no throttle response at all, downshifted her to the side, checked the code (27DA) cleared it, restarted the car, and all was well... Couple hours later I jump in to go to work, car starts, idles rough, and then TURNS OFF! Start it back up, limp, pull some more codes (36E4, 28AB, 28A9, 28B0, 0000, AAAA) cleared em, restarted, drove to work at 14.5 psi no problems, no lights.

That sums up the past 24 hours of mixed feelings of how beautiful my car looks and how crappy the half engine light is. I've tried looking for a complete solution, I just don't know where to start and some of these codes I don't even understand. Can someone give me some advice on where to start, it seems so random. I don't even know how to blame the detail guys or not, what could they have messed up? I'll definitely remove the jb4 when I have some free time this week when I have time, but am hoping to have a reliable driving car until then.

All advice and suggestions are appreciated, and thanks for reading!

Thanks to Terry he sent me an n55 code list and everything points at the throttle, so I'm guessing these bastards sprayed the crap out of it. Not cool. Gonna hope it dries and gets better, or they'll have hell at their doorstep!

I'm assuming by throttle you mean gas pedal? Most likely from cleaning that area.

[Dhillon92]

Yup, I said throttle because all the codes were throttle valve and low throttle sensor voltages and related. But yea it is definitely from cleaning the gas pedal area, just a heads up for someone who may come across this!

It's possible you have a low battery. If they had the doors open for a long time while cleaning it would drain it. Weird stuff happens when batteries are low or dying.
