Hey guys, I bought my 2011 e90 Bmw 335i about 5 months ago and it now only has around 52k miles on it. The other day while my dad was driving my car, it went into limp mode and 2 days later it completely died after I started the car and put it in reverse.
I pulled the following codes:

P0003- Fuel Volume Regulator control circuit low
P15D9- ????
P0031- Heated O2 sensor 1 (catless dp)
P0037- Heated O2 sensor 2 (catless dp)

Before all this, the car would take a bit longer to start than usual. I installed a new battery, but it still cranked hard and strong for a bit too long before starting up. I assumed it was just because of the cold crank amps of the oem battery.

I would take it to the dealer for a diagnosis, but I currently have jb4, catless downpipe, and an aftermarlet chargepipe installed. Not sure if the dealer would want to work on my car with everything installed.

Anyone know what it could possibly be?
1. Is there a fuse for the fuel volume regulator?
2. Could it be the high pressure fuel sensor that's om the fuel rail?
3. Is it the fuel pressure regulator that sits in the gas tank?

Im skeptical that at 52k miles I would have to change a part out, and the codes seems like it may be an electrical issue. Regardless, I'll replace whatever needed for the car to work properly.

Any help would be appreciated, thanks!

did you only get the generic P codes or do you have a BMW specific scanner?

from the control circuit low message I would guess that you've had some sort of fuel pump failure.

I do not have a specific BMW scanner, but my OBDII was able to tell me that all the codes were generic, except for the P15D9, which it said was BMW specific.

I'm really hoping it isn't the hpfp. Also, I thought it was improved on the n55 motor and my car doesnt have that many miles on it.

[nsjames]

see here for n55 fault codes.

https://bmw.***********.com/threads/n55-codes-list.580/

but really you need ista or some other can bus capable reader to get data and real codes out of it.

I replaced my HPFP at 52k miles. It can be a possibility because my car used to shut off randomly at a stop light and I've gone limp mode only once before I had my car diagnosed by a mechanic. I didn't get those codes though. I got codes for lean condition and misfires.
I'm at around 53k miles right now.

[Ace14fly]

Thanks, This is what It says about each code:


p0003:

"Fuel-supply control valve, activation: short circuit to ground"

"The diagnostic function monitors the flow-control valve's control-activation wire for shorts to ground"

"The fault is recognized by the driver circuit diagnostic function.
Potential problem source(s):
-Defect in plug or wiring harness between DME and flow-control valve.
-Defective flow control valve
-Defective DME"


--------------------------------------------------------------------------------


p15D9:

"Terminal 15N_1 power supply switched by CAS, electrical: Short to earth or open circuit"

"The diagnostic function monitors the voltage-supply wire to Terminals 15N_ and KL87_1 for an open wire or short circiut to ground"

"The diagnostic fault code is logged wen no voltage is present at the DME input (KL87_1 or 15N_1) although the main relay has closed.
Potential problem source(s):
-Fuse defective.
-Defect in wiring harness between main relay and DME.
-Main relay defective.
-Defective DME."


Could it be possible that I just have a blown out fuse? It says something about terminal 15/87, but I checked my fusebox, and I don't even have a fuse at 87.

Thanks again.

[nsjames]

possible.

it's also possible that your code reader has read the code incorrectly.

like I said, generic OBD codes are next to useless in diagnosing an issue like this.
You need a can cable and ISTA.
check the bimmer geeks website.

[unrulyteach]

Get ista or bmw scanner and try again

[Ace14fly]

I just ordered a can cable off amazon, should be here in a day or 2. Do i just download ISTA and run the application when my laptop is plugged into the car? Thanks

Yep then do complete diagnostic and run the ABL test if possible. It's pretty straight forward

[sicknick530]

This looks like the right place to ask for help. My issue(s) seem to be along the lines as everyone else here. You guys seems like you know more about this issue than myself. I have a 2011 e92 with the n55 engine jb4 installed 2 weeks prior. So here it goes.... I pulled out of the gas station last week minding my own business, driving downtown about 25 mph & BAM out of nowhere I get the "engine malfunction-restart not possible" message and the machine I love so much just dies nearly leaving me stuck halfway in the road. I immediately ran the codes using my jb4 which were: 2e12 2de3 2de4 2de9. Had to tow it home & now after going through everything I could think of checking, I'm stumped. Now battery is dead (low voltage warning came up twice in the week before dying) was a new battery (jan2018) and now there's another new battery but still won't start. Just keeps cranking. Almost sounded like I had combustion a couple times but no start. I replaced the plugs (gapped .32) and coils 100 miles before it died due to a slight "blip" rpm's on idle only on cold starts. "Blip" maybe once every 5 seconds.
Taking it into dealer to work on isn't really logical for me financially. It just hit 70k miles and is my pride & joy. I'm devastated & need to figure this out because it's consuming my entire life right now. I appreciate anyone's willingness to share their knowledge with me.

[nsjames]

most of those errors pertain to the valvetronic.

looks like the valvetronic motor has either failed, or is jammed somehow.

[sicknick530]

That's what I'm afraid of. I'm hoping, praying its something else. The valvetronic/essentric shaft looks to be a job for the pro's.

[nsjames]

you can easily swap the motor.

the sensor requires the valve cover to come off.

but I'd first start with making sure that it gets power and the like.

no.

but your error code is related to the O2 sensors.

[agy2k2]

Hey ace, did you ever figure this out? I have an n55 car with the same exact 4 codes

P0003- Fuel Volume Regulator control circuit low
P15D9- ????
P0031- Heated O2 sensor 1
P0037- Heated O2 sensor 2

[Ace14fly]

Hey, man.

I never got to the bottom of the problem, as I was just able to trade in my car as is at the BMW dealership I had a personal connection at.

But before that, I ended up swapping the High Pressure Fuel Pump from one I bought off ebay. The supposed "revised pump". Once this didn't work, I ended up taking the car to the bmw dealership for the techs to figure it out (they were all comfortable and familiar with jb4).

They first claimed that my jb4 was the fault. So I literally uninstalled it in the parking lot. When I opened up the white DME box, I actually noticed that the brown fuel wire had come undone from where jb4 instructs you to crimp and bond onto one of the DME wires. Strange, and could be the problem I thought.

Once fully removed, they diagnosed my car again, and the code was still there. No difference. I am trying to remember what code it was, I have since misplaced the print out they gave me.
The next thing they claimed was that the HpFp I got off ebay was not rated producing enough pressure since it wasnt a genuine bmw part. (This could have been it.)
Another indy mechanic who works on euros came to the conclusion that my DME was fried. Not sure how accurate this was, as he only pulled codes and didn't spend much time.

So in conclusion, to sum it all up, I never 100% figured out what was wrong with the car. It was a 2011 (last year of shitty hpfp), so im like 90% sure it was probably the pump, and that my DME was fine. (Jb4 is pretty safe). I hope this helped, others might be able to guide you a bit better, as im no expert. Just wanted to share what happened next. Goodluck and keep your head up!
