Hey guys. I’m new to this forum. I’m in the USA.
I recently got a 2011 335D. It was 157k miles. Fully loaded, well taken care of, drives perfect.
When I got the car it was in limp mode, dpf cycles were never fully completed, I had a ton of codes. I borrowed a Snap on tool and did some on board testing I cleared everything, did a full dpf cycle that cleared up all the codes except for ONE.
Code 4580 - Rail Pressure Plausibility Delivery Controlled.
The car runs nice without the SES light AS LONG AS I’m driving and fuel is being delivered. If I were to drive from NYC to Florida the car will run fine no codes nothing. The moment I come to a stop, SES comes on and the rail pressure is very high.
Anyone here had this issue before? I don’t wanna start replacing parts without knowing wtf is actually going on.
I owned a bunch of e36s, had an e34 an e39. I work on them not problem but this thing is more advanced and I don’t wanna waste money.

I will be replacing fuel filter, air filter and I will do an oil change this weekend, but I'm sure it won't fix whatever the problem is.

Thank you.

Anyone? Noone?

Don't think we've really seen any of that kind of stuff. I believe that you'll have to replace the fuel rail check valve. There are several training docs that explain the fuel rail system; look here: http://www.bimmerfest.com/forums/sho...d.php?t=541722
(I think they're posted here, too, but maybe more accessible on bimmerfest.)

Also, look at realoem.com - it should have the part(s) in there.

You’ve got a response on your FB post. Nothing else to add from my side except to what I posted there.

I ordered the flow control valve. Getting it tomorrow and I will replace it immediately. Posted this around the same time I posted on the facebook group, just trying to reach out to more people to see if there’s anybody out there who had this specific code. I’ll post on here and on Facebook after a test drive tomorrow.

i had a 4580 code with a pier burg fuel pump then i replaced with a VDO and now have a 4560 code (fuel pressure too low) already have replaced the hpfp, fuel filter, main return line to tank, rail pressure sensor and pressure control value and have bleed system many times but i haven't reset the mean quality adaptation because I'm unsure if my diagnostic tool has that function and if that could fix it

[CaptainBluu]

Have you replaced the flow control valve itself when you replaced the HPFP?
Any idea what it would cost going to the dealer and request an adaptaion reset? Is that even a thing?

[ptpending]

you should not replace everything you think but use rheingold or ista software to perform guided checklist when error code is active
software will ask you to perform various checks and using bmw engineer experience and statistics say what you have to replace and in what order
this is how dealer electric work
we have plenty of the diesel cars in europe (actually more than 50% of e9x bmw in europe - diesel)

I am doing research regarding diagnostics software but it gets very confusing. I am not sure which version of ISTA I should use for my car. Can you please point me in the right direction? Thank you.

you can get any because ista or rheingold usually newer that most e9x
the one another check is to check injector volume correction which can be viewed in inpa in dde when engine is running

Unless you're an IT guy, the easiest thing to do is send a message to bimmergeeks. They will remote-in and install not just ista but several other useful programs. It costs about $40 if memory serves. You'll need a cable to use the software. They sell those for $20-30 again, if memory serves. Most worthwhile sub-$100 purchase I've made for this car.

Yes the hpfp came with a new sensor on it and before replacing the hpfp i had installed a new sensor on the old hpfp

So were you able to figure out what was the problem or still struggling with it? My flow control valve is arriving tomorrow. We’ll see.

[CaptainBluu]

Replaced the Flow Control Valve today and the problem still exists. I am installing ista d right now on my laptop, just have to wait till the bimmergeeks cable gets here and I'll do some diagnostics.

My 2011 M57 w/ 82,000mi just started popping the 4580 intermittently when backing off throttle at lower speeds, particularly when cruising at 30mph and letting off the throttle in a descent. If I keep the speed and throttle higher (i.e. drive more aggressively) I can go engine start to stop without getting the light. On average, the car gives me a 4580 about 1/3 commutes, which last about 22 minutes, and almost always in the previously mentioned parameters.

I saw the mx write-up for troubleshooting, but a lot of those processes seem above my skill level or require several special tools. Any recommendations for "most likely" cause I can test for easily, or should I just bring it to a trusted shop and cough up the cash?

Replacing vacuum lines doesnt require any special tools

Unfortunately I was not able to figure out what the issue is. I also went back and forth with Andrew Rodriguez from JR and we ended up knocking out the trouble code AND the limp mode from the DDE. He has only come across 2 other cars that do this and wasn’t able to fidure out the issues. EVERYTHING fuel system related was changed on all these cars. And when I say everything I mean EVERYTHING.

The code being knocked out did not fix the actual issue, it’s more of a coverup, but the car works fine, no issues no leaks no problems. It idles a little rough because of the high rail pressure bit you’ll get used to it.

Ahh yes, the vacuum lines. Probably time to do that anyways, though I doubt it's casual in this case.

[Yozh]

Vac lines will not help you with 4580, 4530 they will but not 4580. Most likely your fuel flow control valve on the high pressure fuel pump. It’s not s bad part to replace. About $100 of you get a Bosch part and not a BMW branded one. Three torx bolts. You can do without removing the manifold if you got long enough torx bits.

I changed that too. I changed everything in my fuel system, except for the low pressure fuel pump. Like I mentioned before, I was so fed up with this I just ended up having Andrew Rodriguez completely disable limp mode and delete the 4580 DTC from the DDE. The problem still exists, it's just covered up. No "issues" ever since.

Thanks Yozh! I'll give it a try this weekend. Does anyone have a part number for said control valve? It seems there are several similarly named parts available...

[WampumD]

Replaced the control valve mounted to the hpfp, and have had no problems for over a week. I frequently tried to put the car in the same parameters that caused the 4580 previously, but it runs smooth as butter in a hot pan now!

Thankful for this forum and the knowledgeable people like Yozh.
