Great videos!! I've been researching the 335i before I buy one for my 2018 daily driver. Your videos make me satisfied enough to go ahead and start searching for one to purchase.

Took care of this sensor today along with my alternator voltage regulator. I took advantage and cleaned my throttle body while it was uninstalled. Really appreciate the great content

I just wanted to say, Thank you for your videos!! You gave me the confidence to fix a bad low pressure fuel sensor and valve cover cover gasket. Look forward to your content.

I just got a Bosch version of the new BMW updated LPFP sensor for $40.00 at FCP Euro. I will installing it this weekend. I’ll probably pull the negative off the battery the night before and then change it on a cold engine with no fuel pressure built up! :)

Great video. Followed it to change mine without issue

I want to thank you for the hard work you put into making these videos and telling us about all of these things. I just bought a 2008 335i and I got an extremely good deal for it because it has these exact type of problems. It's my second n54 335i but I didn't have my first one long enough to experience these problems. So I did a data long about an hour ago after getting codes for misfires (I have ordered new injectors, well, used ones as I just don't have the new money now. Plugs, coils, valve cover, Cam sensors on order) and the code 2AAF "Plausibility Low pressure fuel pump". With Pro tool on my android. (first time doing that type of thing lol) and the read out just revving it at idle was dropping massively each rev. No big driving load even. I had it set to read out in Bar (not sure why lol) and it went from 5.1 bar to 2.9, 3.1, 4.2, etc each time I just revved it to no more than 3500 rpm. So from what you are thinking and what I'm understanding is that my sensor probably works but my LPFP is likely shot. I started misfiring bad on cold starts then after it warmed up it was driving fine after clearing codes. Then today it didn't recover and stayed missing and limping. Very bad. I wish you'd be able to answer me but I'm sure you won't even know I wrote this LOL. I'll just have to dig as much as I can on it all and hope I get it right tomorrow when I go to buy the part or parts. Thank you so much again for the great info and videos!

I'm glad you're doing this. I'm having the exact same issue; I'm really eyeing my rail pressure as well as LPFP pressures. I honestly think it might be my stock diverter valves. So far for the hesitation issue; I am starting to have it post cam position sensor failure. I replaced the exhaust side sensor, and now I am at a loss. I am having hesitation throughout the entire rev band only on very slight throttle; 5-30% accelerator. I've done both boost solenoids, both cam ledges, both vanos solenoids, both check valves, a new oil filter housing cap with o-rings, new oil, new NGK spark plugs gapped to .022." I am holding vacuum very very well, and I still peak boost to 19ish psi. I can't for the life of me figure this out, next will be to change the stock charge pipe to aftermarket with a BOV instead of the stock DV's. This issue is ridiculous man, surely I thought throwing parts at the car would fix stuff. I have been watching a lot of your videos lately, you've taught me a lot in terms of coding, i've coded the hell out of this car myself successfully with your videos and I truly appreciate your down to the last drop style of videos on youtube. I come to equate you to being just like me! We are very similar my man! Similar car similar problems and a similar urge to fix it ourselves no matter what. I hope you keep us all updated and if anything shoot me a pm I'd love to have a chat with you regarding this damn oscillation/bucking issue on light throttle!

Thanks for the video I’ll be doing this after I get home from work. Mine is stuck on 49 PSI.

I'm currently having fuel leaks but I think I found that its leaking from the main feed line and dumping fuel on top of my pump hat, so I wanted to know if the o ring kit you have linked has the size I would need for that line and maybe the smaller line while I'm at it. Much appreciated if you'd get back to me. Great content as always btw 👌

What scan tool and App are you using to scan your BMW and clear adaptations? I have a 2011 535i X Drive and a 2015 X5 50i. I am tryin to find a scan tool which will work for both models as I work on both vehicles myself. I considered the Bavarian technical scan tool but it will not read F model codes.

hi thanks for the video. i do have a question. What software you are using for the video in your BMW

Can you share where you purchased the sensor. Do you think thos would cause misfire codes? Changed plugs and coils already. Thanks

i fitted a k&n replacment filter...when i fired it up it missfired and ticked for 10 mins...then went normal with a deeper sound...is this normal....i started it up from full cold any info would be greatly apreciated

Thanks for your great videos. I noticed you didn't replace your fuel line with the new style fuel line. Is that necessary?

How you check the fuel pressure in carly, since carly did the updated i don't see it no more

I have a question. Can this cause no start issue? My Lpfp isn't priming anymore. I have tried Ekpm3 upgrade and lpfp upgrade as well, but it doesn't prime. It cranks thou. It showed a code: 2FBE Fuel pressure after motor stop I have changed the crank position sensor as well. New starter new Hpfp new lpfp new lpfp regulator new fuel rail with the upgraded sensor and new alternator. I may try to swap back to the old rail and check for any missing connections. I really don't know what else to look for. Thanks.

What's the Harness connected to the high fuel pump pressure called ? I'm having really hard time finding out

That causes a limp mode? And what's normal reading for high fuel pressure sensor psi? My stays at idle at 680 - 750 and when I drive at high speed goes over 800 but once I press gas give me a negative reading. It depends on how hard I press pedal, then back to normal. Probably -400 or -1200. Psi it could be normal? My low ps never goes below 60 psi.

I’m getting a 2BDA code for Rail pressure sensor, electrical short circuit to ground and a 2BF8 code for Rail pressure sensor, Signal permanently stuck!? Any help would be much appreciated thanks in advance

Hi, what software is used to record and show the data log? Wasn't sure if MHD does it all.

what site are you using to view your MHD log on the computer?

Hey is there a way I could order just the cable for the fuel pressure sensor? Mine is corroded. Any help would be greatly appreciate!

You suppose to install an adapter. For accurate reading tip need to be flat.

Did you get a 29F3 from this? Mine says shorted to positive, reading 6500 hPa (almost 100 PSI). I don't have MHD tune / tuner and with INPA I'm not sure how to read that particular sensor. But I'm about to attempt intake valve cleaning and hit this while I'm in there. I was wondering since your reading froze at mid 50s PSI if you got a 29F3.

Were you getting any fuel codes prior?

Are all these procedures the same for the N55?

Does anyone know how I can read the pressure sensor value using Carly? What's the parameter name? Thanks

Car threw a 29F3, car runs fine but the fuel pressure read 120psi+ then dropped to 60psi, and continued to drop and raise. Should I just replace it or look for smth else? Cars on an upgraded lpfp as well

I have an issue where I get crank no start. Don't really get a code. I don't hear the injectors activate I put another hpfp. Changed cams and crank position sensors still no start

what pressure do you have on the high pressure pump?

My f30 crank cannot start the engine. Sometimes the engine turn on huat for a few minute suddenly turn off. Check engine messsge and drivetrain multifuction. Dealer already scan the fault is high pressure sensor. Its is true the sympton of high pressure sensor fault?

Hello, I already bought and installed the new bosch sensor and the problem continues to come up with the same 2AAF code, any advice?

Hello, I want to ask about N55 F87 if you can help, do you know if there is 2 fuel sensor for only one?

My car is a 2009 bmws 335i drive, will i need the ring?

Does the 29f3 cause u not to hit boost?

hey man ! i just got a 2AAF code ... carly saved some live freeze data and it says i was at like 6k rpm and the pressure was like 65 psi ... do you think its the lpfp or just the sensor?

What was the pressure value with the old sensor?

So your old sensor was reading 55.7 therefore the car was always asking for more pressure in theory. It's nice to see you can swap to the new version of sensor instead of replacing the entire low pressure fuel line, just by adding an O ring to the new sensor.

Where did you fine a lp sensor for that cheap ?

Hi brother . please help me. Everything is fine in my car, no errors. but there is a whistle (creaking) in the fuel line leading to the HPFP. Is it possible that the sound is coming from the low pressure sensor? . BMW e60 N53B30

what program are you using on the tablet?

Good replacement...should just upgrade Lpfp to stage 2 for around 300 bucks....at least this way you could run a fuel mix giving you more power gains. and with higher octane i believe its good for the engine.

How can I make sure my issue is the sensor ? I’m getting a consistent 2AAF code , is that what that is ?

Respekt you are best man with Bmw I want ask you how I can talking with you cause I have problem with my BMW f10 530i n53 since two months and I can’t lose it I want send you diagnose mybe you can help me

What app are you using to diagnostic

I replaced my lpfp and sender unit today. I am still getting idle dips and definitely feels down on power, but its much better than it was before. Gonna do the hpfp and the two fuel sensors next. I am at 190k so, i can guarantee that the hpfp is dying. No limp mode yet

Hi thank you for this great info. Should I chance mine as well. Driving 80 km it shows 16.6 then I reset it then it runs about 8.7 ??? Is it that needs changing..?

bonjour, j'ai un code p29f2, pensez vous que ce soit le capteur de pression??

What app are you using to read all that

What is being used to read the DME (ipad app where you saw fuel pressure)?

Are they interchangeable

do not forget to do the pressure regulator and the filter in the pass side tank.

My low pressure fuel sensor broke when i tried unclipping it after putting in a brand new genuine Bmw HPFP. Does it cause any issues, i tried plugging it in anyway and it reads a constant 6.0 now my car doesn't target any boost at all. I have the old style sensor so i would need a new sensor and o-ring combo or i will have to replace the whole line w sensor. Most importantly I was wondering if the LPFP sensor causes boost/power problems since after the install of the new hpfp, oil cooler/filter gaskets, throttle body manifold gaskets i no longer target any boost and power is seriously down

How can i download the software of my bmw 335i 2008 please reply my message

I just replaced everything buy this and fuel module m3 but I do notice my hpfp since I installed it it will stay on while switch is on

But it drop to 48 under heavy load

Thank you. Did you ever diagnose the Hezzitation issue?

I get 0 psi on my log from lpf sensor whent back 3 years on saved log and never got a reading car is running good hpfp producing over 2700 psi,hpfp replacd by bmw uner warranty 3 years ago could it be that the sensor is dead ?

What software are you using on the iPad?

What program are you using on the tablet.

I have a code P15DF. Does that means its HPFP or the low pressure fuel sensor? I've had the HPFP already replace twice since I owned the car.

Hey what's up? do you have social media? Im having same problem changed sensor reset adaptations and new sensor is still pinned at 145 and shadow code.

What tool did you use to remove the junction box. Literally just saw you pull it.

big help man suffering the same issue with my tune from wedge car runs perfect but as soon as 19 psi boost fuel pressure drop I have an early n55 with gear driven pump and similar lpfp sensor I have upgraded lpfp walbro 450 changed rail pressure sensor but still have the original lpfp sensor , I have also replaced hpfp replacing the lpfp sensor will be my last effort to resolve this problem,i sure hope it works interestingly if I ease in the throttle all the way to redline np ,but if start from the dig wot all gears by the time I hit 3rd hesitation ! really frustrating !

Parts number?

Nice video! My reading on my lpfp went to 130 psi do you have any idea why ? Code 29f3

Thanks a lot for your great videos, I will change my low pressure sensor at my 335i 2007 but I guess i also need to change the pipe regarding this note I found at internet ? Product Details Low pressure supply pipe to high pressure fuel pump, includes low pressure sensor 13537622231 This fuel feed line brings low pressure fuel to the high pressure fuel pump of your N54 powered BMW. In many cases this fuel hose is a required replacement if the low pressure sensor needs to be replaced because the old style low pressure sensor is no longer available and the new low pressure fuel sensor is not compatible with the original line.

I have the code p10b8

He’s from Texas

Why do all of you have such problems with your n54s in the US, I'm in Australia and I have had my 335i for over 15 years only thing ive replaced is the turbos for tdo4s no other problems in fact it is one of the most reliable cars i have ever owned, let me geuss you lot insist at some time to use E85 fuel and that is the killer, your fuel isnt the best anyways in general.

You've mixed up two parts. The low pressure fuel sensor and high pressure fuel sensor... www.ecstuning.com/b-genuine-bmw-parts/low-pressure-fuel-sensor/13537614317/ www.ecstuning.com/b-genuine-bmw-parts/fuel-pressure-sensor/13537622231/

What tablet and what program you use?
