2010 E91 328i X-drive. I installed a 3-stage intake manifold, got the ECU back from Turner today and popped it in. Car starts but is revving and throwing a lot of CCID codes:

351 - 4x4 & DSC Failure
419 - Drive Malfunction
24 - DBC Dynamic Brake Control Assist Failed
354 - Start Assist Inactive
29 - Engine Problem - Power Reduced

Okay, went back and tried again. Car is now running more smoothly (not revving) but is giving me the warning symbols for the 4x4 issue and the engine issue with these codes:
351 - 4x4 & DSC Failure
354 - Start Assist Inactive
29 - Engine - Power Reduced

My questions:

1. What could I have done wrong or could be wrong with the install and reconnect of everything?

2. Could part of the problem be the PCV breather hose that most write-ups say will likely break when removed? Mind did not break (that I am aware of) and seemed in good shape and pretty flexible, not brittle at all. It may have been changed when the valve cover gasket was done before my ownership. I reused it, although I do have a new one on hand.

3. Could there be something wrong with the tune? Could Turner have flashed it for a RWD rather than an X-Drive? Would that cause the 4x4 warning?

Need to reset adaptations. Can be done in Bimmergeeks Protool and INPA.

Also do the throttle adaptation reset. Turn car ON but don't turn the motor on (foot OFF the brake), all the electronics will come alive. Hold gas pedal for like 10-15 seconds, release, and turn the car off, then start it. Clear codes afterwards.

Doubt anything's actually broken, you just changed a lot with the car and everything else needs to catch up. All these cars' computers talk to each other a lot (CANBUS), so for example when the ECU's parameters change, the DSC module will be angry until you reset it.

turn the wheel lock to lock.

probably all te 4x4/dsc lights will go out.
it's steering angle sensor things.
happens everytime I disconnect the batery on mine.

Okay, that took off the 4x4 light and code. Thanks!

Okay, I did the throttle adaptation reset. How do I clear the codes? I know how to view them but will have to research how to clear them.

[nsjames]

what diagnostic software are you using?

[hassmaschine]

You must have disconnected the battery to swap the ECU out? FYI, it's really not necessary to do that.

Man, I hope you didn't pay a lot for that Turner flash...

I do not know much about Protool or INPA. I've got the Carly software but I don't think it does the same things. I do have a Bimmergeek cable. What else do I need?

Yes, I did disconnect the battery - it was in the ECU removal instructions I found. Others I have seen since do not say to disconnect battery. The Turner instructions, which I didn't get until after I had removed the ECU, say to "Power everything down inside the car – radio, navigation, A/C, even lights. Unplug anything that is plugged into the aux port or cigarette lighter. Plan on not accessing the car at all while the DME is out of the car. " Well, water under the bridge.

The Turner flash was under $500 - what is the problem with the Turner flash?

I have the Carly software and have done a few coding changes but that is it. I am a rookie in this area. I have a BimmerGeeks cable that I bought when I was thinking of doing the free Bimmerlabs tune but I decided to go with the Turner tune instead, thinking it would be less complicated for me. I've never done anything with diagnostic software and though this might be too big a project to start with.

[nsjames]

carly can clear all of those.

I would clear everything and then see what comes back.

I commonly get random strange error codes after a battery disconnect.
if it still comes back with power reduced and other DME specific stuff, I'd call turner.
I assume it all worked prior.

Yes, I cleared the codes with Carly but still getting CCID 29 - Engine Problem and in the Carly report:
Throttle 1
Code 002CF9

Throttle 2
Code 002CFA

throttle
Code 002D09

Poking around to get some more info on these codes I found on BMW Fault Code Lookup (bmwfault.codes)
2CF9 DME: Throttle-valve potentiometer 1
2CFA DME: Throttle-valve potentiometer 2
2D09 DME: Throttle

Trying to figure out as much as I can before going back to Turner.

that sounds suspiciously like the connector at the throttle body.

Mine practically fell apart inside when I swapped my intake. Was a struggle to put it back together. You may want to check that. or see if carly will let you look at the raw values. I'm not sure if you can or not under the dashboard. I use ISTA for real diagnostic work, carly is just handy for portability.

anyway, I still need to repin and replace my connector body, but if it ain't broke I ain't messing with it. I did get a disa error on my used manifold the other day, so maybe I'll be dealing with it because I'm pretty sure I'm replacing a disa valve soon.


FWIW the bimmerlabs thing was not difficult. the script sent managed everything for me.
It may be an option if you want to figure out if it's a problem with the tune or the car. My money is on something in the cars harness that you've messed with as part of the swap.
but those errors are basically saying that what the DME thinks the potentiometer on the throttle blade should be reading doesn't match with what it's actually reading. It could certainly account for random revving and craziness.

Okay, it was me! I was the doofus. The throttle position sensor was not connected properly - not seated all the way in. With the codes I got from the Carly diagnostic, the Turner guys thought it might be the TPS and it was. All is great now - car is much quicker on acceleration and has much more pulling power, just feels so much . . . more.

Thanks for all the input.

You are right - it was the throttle position sensor and I was the doofus as I had not connected it completely.

[hassmaschine]

Don't feel bad. Shit like that has probably happened to all of us. Glad you solved it!

When I put our X5 back together (a couple weekends work to replace a $5 gasket, don't ask) - I forgot to plug in the level sensor for the power steering reservoir. It turned out I didn't even need it unplug it in the first place, but in any case - when I first started it up after putting it all back together, I got all sorts of ugly, horrible errors about how the car was totally hosed and I should probably just take it to a shop (or maybe light it on fire, IDK).

I sweated a little bit (honestly, fuck this car), but I just thought about it logically and then I remembered the one stupid plug that I didn't reconnect..

This is a great thread. Thank you for all of your follow up notes on how you solved the problem.
