Big thanks to Jin & Steven at Active Motorwerkes for checking the car.
Luckly the problem wasn't a big issue, Jin replaced some of the hoses, old one is starting to crack.

Just wondering I'm having this issue but only after the DP was installed?

Is it possible that the o2sensor was fitted wrongly??

How can I check the code via jb4? I know you put read code but I dont know how to read the code as all the dash does both blinkers flashing that's it.

You'd need to plug it into your computer and read it off there Troy. At least that's what I'd have to do with my procede

Whats the issue you have? Under WOT then it goes to limp?

You probably need to update the map also troy as you have intake dps and exhaust.

Another thing I've read about DP installs is that sometimes they can be installed too close to the wastegate actuator arm which forces it to stay open and can give codes.

Yup, cobb procede jb4 they all require a new map to be uploaded to suit the mods as you add them.

This is what I had learnt after the recent advan dyno day and my dissapointing results (due to running a very mild stage 1 map that was initially uploaded when i was sans intake dp's fmic cp etc)

Contact jb4135, im sure he would help you out (chuck in a 6 pack of beer/bottle of spirits etc if he does help you)

P.S This wouldnt be the cause for why your car chucked a code and went into limp though...

I found this when i was searching for answers on why my dyno result was so low:

With different tunes in the market and there recommended stages for different maps, whats the ideal bolt-on to run what tune and different stages?

COBB
Stage 1 - Stock Car
Stage 1+ - Stock + FMIC
Stage 2 - Stock + Catless DPs
Stage 2+ - Stock + Catless DPs + FMIC + Upgraded Intake

JB4
Stage 1 - Stock Car (Map 1)
Stage 2 - Stock Car + Catless DPs (93 Octane) (Map 2)
Stage 3 -
Stage 4 - Stock + Catless DPs + Upgraded Intake + FMIC + Methanol + Upgraded Turbos

Procede v3
Stage 0 - Stock Car (High altitude & poor fuel quality & high temp) (Map Stg 0)
Stage 1 - Stock Car (Map Stg 1)
Stage 2 - Stock + Catless DPs + FMIC (91 Octane) ; Stock + Catless DPs (93+ Octane) (Map Stg 2)
Stage 3 - Stock + Catless DPs + Upgraded Intake + FMIC (Map Stg 3)
Stage 4 - Stock + Catless DPs + Upgraded Intake + FMIC + Upgraded Turbos (Map FBO Upgraded Turbos)

FBO = Tune | Downpipes | Intake | FMIC | Cat Back Exhaust (Optional)

Also check the vacuum link I posted on page 1.. Seems a lot have that issue around 50,000 onwards k's.. It's something you can check yourself in 30 seconds..

Although it happened after the DP install, it's possible it's nothing to do with the DP's (or surrounds) themselves, but more the fact that you're just running more boost..

I had two issues when upgrading to COBB and DP's:
First was a coil and plug replacement, and then two months later, it was a vacuum leak, which was fixed with a $5 hose.

This is my daily, is it safe to drive it around (50kms per day) for the next 3 days until i have time to bring it to a BMW dealership?

Any advise on what it could?

It's a 2007 BMW e92 335i (Step) with 56,000kms.

Cheers!
I had this same thing happen to me on the weekend. I was driving back from the Country and all of a sudden the light came on. I stopped to get petrol and when I turned on the engine again, the light was gone.

* The car is stock except for a procede tune.
* Its over due for a service.

Should I be worried?

Hmm not really, hook your laptop up to see what codes are stored?
