Anybody know the significance of the code P29DC "cylinder shutdown?"

[skatenc123]

FIRST OFF im not sure if the information i am giving is 100% correct but after looking into "cylinder shutdown" i couldnt find anything with that code i found this. "If a particular cylinder is experiencing a misfire that is bad enough to cause damage to piston rings, valves, cats, etc, your ecu will cut off fuel to that cylinder to prevent any serious damage." i would try sparkplugs and coil packs, and see if the problempersist.

Yep, it should show everything.

If you are getting codes at the drag strip, and don't know what they are, best idea is to err on the safe side and call it a night.

Thats what I ended up doing. Sucks but hopefully I can figure out whats going on soon.

P30FF is a boost leak code. Ive never heard of a "cylinder shutdown." i suggest getting in touch with Cobb ASAP.

I know you were trying to be empty before filling up with high octane, but you should never drive to you are literally empty. You'll start sucking up all the crud that settled in your gas tank and that will foul your fuel lines and injectors.

Hopefully it's only the injectors!

I agree that's the worst thing to do is running out of fuel completely .Last week I ran my tank till it said 3 miles left in the tank cause I wanted to change fuel stations and see if I feel the difference from shell to mobil.The worst is running out will suck my all the garbage in the tank to your injectors like nafoo said.wow these cars will tell you of you have boost leaks?looking forward to Cobb stage 2 + did lots of research and I'm liking what I'm reading this far .

That's all I keep reading that it's a beast .How so?

[rader1]

it's not really something i can describe... it just puts a smile on your face. That's the best compliment you can give something IMO

I finally got some error codes 5 in all:

P2097
P0041
P2C31
P2C6A
P2C28

most are cat leaks or something.

I just stepped my game up to Stage 2+FMIC and its nice to have the Stock Throttle mapping back (normal Stage 2+ didnt have ST maps available)...Car has been a lot of fun and pulls like a freight train!!! Big smile on my face ...Only issue I have is slight surging in the 3-4k rpm range but I already hear Cobb has a fix in the works...once that is fixed the car will pull much more predictably..

Hope to get some new updates from Cobb soon

The fuel tank has a special design with a pocket which collects all the impurities/debris. That pocket will keep filling with impurities for the life of the car. Or at least that's why a BMW tech told me.

Have manual stg1 aggressive, MT and still 'surges' so it's not a AT thing, or a stage 2 thing.
(strictly speaking it feels like DTC is intervening at around 3k to 4k and then lets the car get the full beans)

What I find interesting is that stage 2+ boosts up to 18psi even at minus 8 degrees Celsius (just tried that out last night).

I always thought the DME was working with load targets and that these would mean that at colder temperatures the boost would be lower as well (colder air equals denser air). However it seems that such is not the case here.
