This throws error codes - BMW E90 Low Pressure Fuel Sensor & Pump DIY

Thanks to www.oembimmerparts.com for sponsoring this video.
The original low pressure fuel sensor design placed it a little too close to the engine and the excessive engine vibrations caused it to fail. BMW released an updated pressure sensor design with an updated fuel line which relocated the sensor a bit farther away. Along with that, they changed it from an o-ring to a tapered compression fit. But, that fuel line is rather expensive and you can just get an adapter to put the new sensor on the old line. Will this eventually cause the new part to fail since it's still close to the engine? Perhaps, but I'm ok with that as it's super easy to change. You can replace the whole line if you'd like to, it's up to you!
New style sensor:

oembimmerparts.com doesn't carry the adapter so you'll have to source that elsewhere:
Adapter part number: 16124800029
O-ring (for adapter): 13537559991
Or you can just get the old style sensor:

2DED usually means you have some kind of battery drain. For example I was getting that code a lot from my comfort access handles draining battery a little bit.

Have you yet changed the LP fuel filter unit that’s in the other side of the gas tank? I’d like to see you do that. Thanks.

[@fcknhellmate]

These connectors are often called Type A Hirschmann's (THEY ALWAYS BREAK - unplug them enough times and even brand new ones fail), but little known fact is that you can repin them and swap with newer style Type B SealStar Hirschmann connectors. Obviously you have to swap also sensors to newer style, but these are relatively cheap used and enable very easy swap to 3.5BAR TMAPs ;)

[@fcknhellmate]

Also I love the new intro :)

Hello there 50s kid, great fan of yours and been watching your videos for a long time from my E46 to E92 now, you've been helping me a lot on my DIY maintenance. Recently I've been experiencing long cranks regardless the car is warm or cold. I've read fuel pressure when pump on (INPA) and car off, reading was fluctuating at 36 PSI, does it indicate a bad pump of bad sensor?

[@kaviortsang408]

FYI car is now 80k km and it's an 08 335i.

[@shaazy]

Really good video. What year is your 335i? I was very excited for the moment of truth and kinda bummed it didn't cure yours. I am having pretty similar symptoms, I get cylinder injection cutout 29DC at full throttle when the car is warm, it starts running rough immediately but when I turn it off and back on, it smoothens out. My pressure readings are even worse, as of yesterday, 2400 hpa at idle which is about 34 psi when in fact, it should be near 72 psi. Had almost pressed the button on low pressure sensor and pump before watching this, but now gonna wait it out. lol ... cause the only other item that may be at fault is hpfp, which is about $900!

[@50sKid]

It’s a 2007. You should replace your low pressure fuel sensor.

[@KillSaint]

the end of the video got me 😂😂😂😂😂😂 this better work

[@arthuresclamada1805]

Not sure if this is an issue, looking at the DTC they are "history" not "current". So why the fix? I have a similar issue with my volvo xc90 but it wasn't the fuel pump, it was the failure in the pump module (PEM) this trigged an error code for the fuel pressure sensor as well as fuel pump. The fuel pump and sensor are ok, it's just the cascading effect on how they are dependent on each other.

[@philipandrew9915]

For people struggling with low fuel pressure I solved to problems I'd like to share there's a grey fuse box near the ecu they have fuses in them for the injectors not sure which ones but on replacing two blown 20 amp fuses I had power to the injectors the next problem I had was cylinder 1 activation it turned out to be a bad plug hope this advice may help someone else obviously I'm talking about the bmw 520d,320d,118d etc etc

[@brandon7968]

Hey, I have a 2010, N54 powered E60 that seems to be giving me the run for my money lol The low pressure fuel pump was changed, mostly because of evap codes coming from the fuel filter side. The car never ran right after the fact and was parked for about nine months, I went on to scan it again and realized that the EKPS had gone bad, I went out to an E9X BMW and purchased another one and got it recoded with my tablet. The car ran for the first time in almost a year, and ran and drove for about four days back to back. The car eventually decided to not run again and had been parked since So currently there is a new fuel pump assembly, a brand new battery, and fresh gas. I keep getting the code: “00651B - suction jet pump fault” “00A0B4 - CAS - Engine start, starter operation” I am completely stumped at this point, I don’t even know what else to check. Please help lol

[@Levent_Ergun]

The plot twist 🥲

[@WhatUpTKHere]

I got ISTA telling me to change my fuel quantity control valve on a 320D with an N47. Any guide on how to do that? Is it hard?

[@1ROWDY35]

Hey got an issue with mine, directly after flashing some different mhd flash setting my car staryed and sralled, thinking it was a flash issue i spent the next 3 hours flaahing different maps trying to fix ir, turns out it was my low pressure pumps fuse, i replaced it and car srarted but was im limp mode, now i my rail pressure is equal to low pressure, coukd this be coinsurance or do you think my hpfp took a crap in that exact moment? Seems abit odd to me if the hpfp died like like randomly

[@tl56kmair]

On my car, a 2011 z4 the lpfp is in the bottom of the tank, behind the exhaust.

[@geogeo2551]

Hey there is the Low Pressure code P142E ? I ask as mine have a ton off mods . Stage 2 turbos Inter-cooled all the piping I added a Catch can etc etc. but when I boost it sputters a lot and throws the P142E code . Ps I did the Vanos Solenoids and all that as well .

[@chrisyo295]

I have a 2002 bmw 330i witch gas do i need to use? Is 93 better for the engine or i can use 87. Any suggestions. Thanks

[@fixyourcaryourselflouiscuc8030]

Hey how you doing I have a 2002 BMW X5 and I’m wondering about the transmission

[@cme2nite123]

Hey 50kid so if it’s running @ like 65 and when I hit it it goes to like 35-32 do you think it’s my lpfp or hpfp

[@daineseboy78]

Just something to note the battery voltage looks low. I’ve had a few German cars now and they all hate when a battery is low or weak. Just wanna make sure that’s not throwing you a weird curve ball

[@ferdi9697]

I have 2AAF since 5 years, car is running fine. It is ok to ignore this.

[@luccyjayz]

Did you ever figure this out? I’m having same issue but since I’m trying to sell I need to fix it 😬

[@derekkchung]

69 psi is actual but I thought DME desired target is 72 psi (idle or high RPM)... Close enough or it is enough to throw the code?

[@PartiBuoy]

That must be a relief but man that is unfortunate.

[@chrisyo295]

I have a 2002 with a p1093 code any ideas what should it be. Any advice. Thanks

do you use premium gas on ur e46 and e90?

Did you ever figure it out? I have an 07 bmw 335i with same issue no misfire no hard start or long crank. Just the code. I was about to try the low pressure sensor but saw your comment lol. Also my fuel pressure is at 66psi so id say it’s ok

[@sharpe238]

I had a e92 and the hpfp was so bad the car shook while it was on. Granted not a cheap part but once replaced it ran like a champ.

Hi kid, my e60 just started sputtering while accelerating. I've looked on line and wondered if you had any ideas based on your experience. It does it cold or warm and started noticing on highway. Thanks!

[@rawnclark]

Probably vanos solenoids. Do camshaft position sensors while you're at it. Fixing the same issue on my E46 m54 they're getting to that age

[@devinsmith4151]

Man you have to stumble across this one, ISTA at times accasionally pops up this fault with fuel pressure. In the end its a test plan that never ever worked out (its a phony one) and allot of people replaced the fuel rail sensor (which is kind of a waste of time). Your better off upgrading the integration level. The low pressure fuel pump lasts a fairly long time, I would probably only replace it if its dead. Just saying in the US the car parts industry must be making big bank since so many parts are getting replaced way before they even get a chance to fail, allot of e-waste generated sadly.
