Hello, so i just updated the firmware on my jb4 and ever since i did my car keeps having this wierd jerk at low/high rpms it only happens when i push the turbo, doesnt need to b WOT but just pushing it will make the car jerk very aggressive.
So i checked codes and it gave me 2774 Mass air flow sensor
I cleared codes and it keeps coming up, its wierd because sometimes the code doesnt come up until it jerks.

E2C7-central control. Error, logic errors/bus communication errors.
Have no clue what errors this speaks of. Anyone?

I got these codes with MHD recently
PS2, div+ GFB, inlet upgrade, FBO with drop in filter

Ive been railing on the car a lot to test a tune and new ethanol/methanol mixes and the new MHD tuner, and these codes started to arise yesterday, but previous days when I drove it harder, no issues at all. Like 300 miles on the setup >.>

The BOV one, I have been taught to ignore from the JB4 days, so not sure..I dont even know how to check to see if this is an actual malfunction, would my car sound different when I left off the gas or anything?

The MAP one is weird, I Cant find any info on it, I had to look up the code via my N55 code PDF I got from a BMW tech.

Shadow code is same as above.

I also got a 2774 code at IDLE, I checked for codes nothing showed up, and I checked again right after (I hit read codes twice by accident) and it showed up!


Car rips though..

Three logs on there, there is a drop down for those not too familiar

For MAP code check your intake.... I ended up getting most of mine replaced when that kept popping up. I think the code i showed was P28A0

Off the top of your head, what was it exactly? Like the intake tract that goes from turbo inlet all way to the filter?

Or the actual intake manifold? I am stock intake box right now with drop in filter from Cobb, literally 300 miles on this setup.

It would explain my MAF code too I guess?

Well it was really odd because it popped up both when I had my Injen on and also when i was back to stock... I believe they replaced all the plastic piping (including the intake tract that you suggest).

I was under CPO at the time and I think they pretty much threw parts at it until it went away.

It remains one of the more elusive codes I have encountered. Sorry I can't point to a more specific cause.

When I am out by the shop I will have it tested, Ill check everything that I can visually though

I can hear my diverter GFB+ 'flutter' when I get out in and let off abrubtly, so I am confident that 2c90 code is crap

Did you ever figure this out??

I just flashed to S1+ and these popped up agian.

P112F and P28A0


Legit barely drove the car too... it has to be a malfunctioning sensor...

Nope, havent driven in last few days, but I've done a few logs, nothing so far. Have a new map to test as well, but it is icy

Just got the P112F , wasn't driving either start d the car it idle for a few minuets then this popped up I cleared with MHD we'll see if it comes back

Hey, did you ever figure out this code or did it go away on its own?

[ANMVQ]

I did a reset of the throttle, adaptions, etc and never came back

[Aseneph]

(I'm assuming) correct me if I'm wrong but

3106- catless downpipe
290A- ????
29D0- misfire cylinder 4

[JB4N]

So is code 2775 normal then when running JB4? Seen various other threads that say it is a boost leak.

I think it might be an ISO tuner code because he mention that the board will run hotter with the diode cut, just my guess.

I know its a while after. But did you ever figure out what this is? Im having the same issue. Cant figure it out.

[null_routed]

Is anyone getting a 3166 code with fbo+jb4?

[Maddeekk]

Stage 1 tune with upgraded charge pipe and catless down pipes, the codes pop up every few weeks.

I'm getting the 2BDE as well.

Let's not turn this into a "what does this code mean" thread.

Additionally, a PROPERLY tuned n55 should have NO CODES whatsoever

Idk I've had a HPFP shadow code with MHD for like 2 years, it's never been active, and I haven't had any startup or driving issues with the car.
