i've recently taken my car to the dealer, and this is what they came back with:

""We have scanned your vehicle to determine the source of the engine light
coming on. The fault is knock sensor #1 & #2 exceeding the
parameters--problem is exacerbated by high outside temperatures and the
use of fuels with low octane numbers.

The correction is to program the vehicle with a certain software
version."

Just to confirm, doesn't this mean that this limp mode would go away if i just replace the gas tank with new batch of gas?

please help.

Did you use 91or 93? Also did dealer update your software?

If you are stock that is really weird and should have them look at it more, if not you were trying to run too high of map without enough octane and you went into limp mode then you're doing it wrong.

i have procede v5 and i run shell octane 91.

i have a custom stereo system, and it requires me to change it back to stock so they can update the software. so if i don't have to do this then that would be ideal.

anyone know that this can be due to a bad batch of gas or some how the gas station gave me the wrong gas?

I don't understand why a update in the software would do anything?

With the new version of Procede, you will go into limp Mode if you don't cycle the ignition and reset adaption.

[3coupe]

how do you cycle ignition? i reset adaptation once and my car had an asthma attack....

mind you, i removed my procede and i still get limp mode.

[s2k_335i]

Cycle ignition = press the ignition once without pressing the clutch. Perform this action 3x. Than go into the Procede command center select mode 3, than reset 11-1 if you have a manual. Good luck...

[3coupe]

does anyone have any other suggestions, or anyone that has experienced the same thing, i would really like to know what's going on with my car.

the dealer is having difficulty communicating with my car due to my upgrade stereo and more recent temperature gauge. I didn't know that swapping the temp gauge would create such a problem for me.

please help!

Sounds like you probably got a bad batch of gas then. Did you recently fill up? Not sure if octane booster might help a bit... I'd probably do a search on it.

[3coupe]

Anyone else can please help me?

Bad gas and/or procede faulty firmware. Im gettig my car back tomorrow after a clutch job and dealer can't help. Anyone's advice or suggestions are most welcome.

[Jeff@TopGearSolutions]

Are you running default map 1?

Which firmware and map versions?

Any logs?

We are all guessing here until we know that and see logs.

[3coupe]

i run map 3-30

strangely enough, this ONLY happens on the highway if i cruise over 110km/h.....so effin' weird.

[Kalimanjb]

The only time i had a limp mode in highway was after putting HESS gas 93

[3coupe]

this is running the newest 6-14 maps. i have reset all adaptations and i still get the 12544 and the 11881 CAN DME Codes.

[3coupe]

here is a larger one.

I'm going limp at highway speeds on occasion in wot or speeds over 85 mph. I use chevron 93 and run jb4 Map 1. I am getting a VANOS code but had my VANOS replaced as well as hpfp and software update just a month ago. Scheduled to take it in next week but would rather solve the issue myself without having to pull out the dci and jb...again.

11881 is a knock sensor fault code. Since it's reoccurring with our without a tune, the dealership needs to fix it. It has nothing to do with resetting adaptations, running different maps, or even running bad gas. You need to get your software updated and/or your knock sensor replaced. I know you're avoiding it because of your stereo but you are just prolonging the inevitable. No one will be able to fix it but your dealership. Let them.

is it dangerous to drive the car in this condition? would it damage the car?

I wouldn't say it's dangerous since you are in a no boost limp mode. Hard to do any kind of damage when you are making ~180hp.

thanks shiv for the quick responses. i'm glad i went with a procede.

its gives me a peace of mind that i can drive this for a few weeks before i have time to get it fixed.
