i'm really sorry if this topic already exists i have searched for it with no luck i'm new here so i'm only learning how to use this.has anybody else taken an engine out of a 335d and rebuilt the motor and put it back in? i would really appreciate any input thank you

[BB_cuda]

Go look for Bodacious at Competition diesel

[decy1000]

ok will do thank you

[decy1000]

also anybody on here have any info on codes = generic p0088 high fuel rail pressure or bmw code = 4580 rail pressure plausibility delivery-controlled. would really appreciate any info on that also thank you.

Here you go. Have you changed your fuel filter lately?

[decy1000]

thank you so much Yozh i really appreciate your reply i have spent weeks researching this 4580 high fuel pressure code and throwing parts at the car thinking/hoping it will fix it and your reply is by far the most informative and accurate solution to my problems thank you. so far i have replaced the fuel filter,fuel pressure sensor,fuel pressure regulator and i have tested the fuel pressure coming from the low pressure fuel pump located in the tank at the back and iv'e tested after the filter under the drivers door just to rule that out also and that's giving me a reading of 65 psi i'm not sure if this is correct or not and i'm still getting that 4580 code putting the car in limp mode.
I think like you have suggested in your reply the fuel quantity control valve is the next thing that i should check and tick that off my list as the car has been sitting for a while so its possibly either seized open or de energized and ill let you know how that goes thank you

I'm having the same exact issue. So far I've replaced the fuel quantity control valve on the HPFP, injector return line, new (used) DDE.
I don't wanna keep throwing parts at it. Were you able to solve this? I've been struggling with this for 2 months and I can't figure it out....

Thank you.

[Yozh]

Have you replaced your fuel filter. Also after flow control valve replacement you need to reset adaptations. Why replace the DDE though?

[decy1000]

after replacing a whole bunch of parts on my 335D the fuel pressure sensor, fuel pressure regulator, fuel filter all with huge expense and no success it was replacing the fuel quantity control valve on the HPFP that worked for me it fixed my car and got rid of the 4580 code.

Also full credit to Yozh it was his advice helped me out and saved me from throwing even more parts at the car thank you Yozh.

PS i'm also getting a generic code P2201 (nox sensor circuit range/performance bank 1)
can anybody please throw some light on this or know how i can remedy this thank you in advance any advice will be much appreciated thank you

[CaptainBluu]

Thank you so much for your reply. So far I have replaced the computer, the fuel quantity control valve, the fuel return line from the injectors. Did you have to reset your adaptations after replacing the fuel quantity control valve? Replacing the fuel quantity control valve did nothing on mine.

Yes I did reset it using ISTA/D. Under functions I selected the fuel quantity control valve and the reset adaptations. Matter of fact I reset adaptations on everything else as well.
I replay of the computer because for some odd reason my fuel temperature sensor reads 3.1 V. All the other 5 V sensors read 5 V. Unfortunately the problem remains. I will try to reflash the computer using ISTA/P and flash factory software onto the computer.

this is how Yozh was able to help me i don't know if you are able to see this in the original post or not but i will try and repost for your benefit.
All the answers to your 4580 woes lay in here. everything that you have done so far cross it off of this list also to answer your question i did not have to reset any of my adaptions after i replaced the fuel quantity control valve on the HPFP all i did was clear the codes with my cheap generic scanner and the car ran perfect after that i hope the above is helpful to you.

[CaptainBluu]

Yes I used ISTA/D and followed the instructions and replaced the HPFP flow control valve. Changed absolutely nothing.

[Yozh]

Have you tried logging?

[CaptainBluu]

All symptoms actually point at the flow control valve on the HPFP. As long as I’m driving on the highway and I keep the RPM range above 2000 RPM the car has no problems it drives fine no limp mode, no codes, no SES. As soon as I stop or coast and allowed the RPM to go low enough to trigger fuel injection the real pressure starts rising and when it reaches about 10,000 psi at idle the limp mode occurs. It would normally be the flow control valve’s (fuel wuantity control valve) job to supply correct anount of fuel. Although the tricky part is that even if the flow control valve does gove more fuel than it should why doesn’t the fuel pressure regulator commanded to open wide open to let go of the excess fuel? It stops opening at around 31% (but when I floor the car and it gives a lot of fuel it opens as far as 90% at times so the regulator must be working properly).

[Yozh]

Our system is a two-stage set-up. I would also be looking at the rail pressure regulating valve and test that with ISTA and log the parameters of it. When engine temperature below 19C and when coasting rail Pressure is regulated by the rail pressure regulating valve, not flow control valve. They work together. Check the valve at the back of your rail.

[CaptainBluu]

That actually makes sense. The other day I was coasting coming down a bridge and I was monitoring the rail pressure and I noticed that the rail pressure was absolutely not changing at all it was not increasing or decreasing it was exactly the same amount the whole time of coasting. But in that case I don’t understand why does it work while regular driving or spirited driving but not working just after coasting. Again, the high rail pressure doesn’t happen while coasting it happens when I hit low enough rpms where the dde commands the injectors to inject fuel. The regulator valve seems to be doing its job perfectly fine while driving.

[Yozh]

From your descriptions I agree that it should be the flow control valve (on the HPFP) issue. However, I would suggest that you log rail pressure actual and requested and in conjunction with duty ratios for both valves, the flow control and rail control as well. There also parameters for requested current vs actual on both that you can test. That should give you a good idea of what is happening with both. Another idea is to log the behaviour of all the parameters from a known good car. Under similar conditions. If you need parameter specs please ask.

Thank you both for discussing the details. I could write a book and illustrate
it since my car changed on April 18, 2016. I have much written and
many photos but the questions keep increasing. A dealer sent me away
with a 2009 that drives a quarter mile then quits, only to restart after
waiting awhile; repeat.
