BMW N54 HPFP FAILURE Symptoms/Codes!

[@Kipitrl]

Took mine to the dealer at 78k said the hpfp was still good. Told the dealer about all of the modifications and they were still willing to check and replace the HPFP if needed. BMW of El Cajon,CA 335i FBO JB4+MHD E85 BEF FUEL IT STAGE 2

Nice. This is my local dealer too. Im in spring valley and having issues with either ECU or injectors, but i have mods

Hey I installed my down pipes today, change to silicone boost lines, coolant change, transfer case fluid, and adjusted my wastegates with 8mm washers like seen on forums. NO RATTLE and the downpipes are intoxicating I'm super stoked O_O

[@defianth7252]

Could you share the info on the wastegate adjustment with the 8mm washer? Does the washer go under under the normal c-clip? Cheers

[@iBryaaannnn]

You did the front turbo too? Can you link it por favor?

[@ltdasilva93]

I googled wastegate washer fix and found mixed forums. I found a member in Niagara falls, Ontario who did it himself and i offered to pay for him to do mine. He referred me to a shop in Mississauga in which I visited. I don't know exactly where the 8mm washers go but this shop I visited knew exactly what I was talking about so I did all my services there that I mentioned at an amazing price. I would recommend, depending where your located, to browse and print out the forums on the fix and visit your local Indy shops to see if they have experience/knowledge on this. I got lucky as this shop was close to my home and I innevitibly prolonged the life of my OEM turbos.

I have a fuel pump plausibility code. Could it be that? I also get a lot of clear smoke through the tail pipes and smell of gas.

[@Spaceman_YT]

Did you ever figure this out? I just got the same exact problem after installing downpipes/straight piped the car

[@thegerm4986]

As for smell of gas you may want to check out the LOW pressure fuel pump. I had the same problem and had switched it out and the smell is gone

[@anthony605]

Great video! I know this has nothing to do with the HFPF. But have you had problems with your side view mirrors never being in the same position (glass portion) after shifting from park to reverse or drive. I always have to re-adjust mine after parking and was wondering if there was a fix or issue with this?

[@mulletor123]

Anthony I have this issue bro.

[@gprnick]

You need to clean the contacts on the motor of the mirror. They get either dirty or oxidized and thats what causing them to miss align

[@Trump-The-GREATEST]

If you suddenly get a P0087 "Fuel Rail System/Low Pressure" and you get a "Drivetrain Malfunction" on the dashboard and car goes into limp mode. U turn the car off for a few minutes, Check Engines goes away when u turn it back on, needle always idles smooth even before and after error code, now it takes about 3 cranks to start ur bmw because it seems the gas takes a bit longer to reach the fuel pump ... Everytime you drive off u cant passed 40 miles speeds at a fast paced because another Drivetrain Malfunction comes on but then goes away when u slowdown and hit the "ok" button on the iDrive knob... Then it could just be that the "Low Pressure Fuel sensor" is failing causing any High Pressure Fuel Pump to throw shadow error codes and that all it needs to be replaced!

[@ericdeng7315]

What about the 2aaf fuel pump pausibility code?

[@IccDani]

did u figure it out

[@Trump-The-GREATEST]

This pump for n54 & n55 BMWs do NOT need to be coded. Just perform a clean swap and ur done! Highly recommend that for any High Pressure Fuel Pump replacement you should change the Low Fuel Pressure Sensor as well since it connects with the HPFP anyways. Might as well change the High Pressure Fuel Sensor also while ur at it!

[@friguy4444]

I wish the diagnosis was that easy for the HPFP. I'm getting only 9 - 10 psi LPFP and already replaced the sensor for the LPF. So if the LPFP isn't pumping the 72psi it's supposed to then the hpfp can't pump the 1600 and higher fuel pressure but that doesn't mean the HPFP is shot does it?

Im not sure if its my injector that's failing or my hpfp, Im getting codes 29CD - Combustion misfires, cylinder 1, 2AAF Fuel pump, plausibility and 2E18 - Firing Cylinder 1. its on limp mode now. Can i switch the injector 1 and 2 to see if im getting cylinder 2 misfire to determine if in fact it is the injector thats the issue? and can i do that without replacing the rings and decompressor rings simply to diagnose? or can i casue damage this way? My original issue was after hard acceleration especially on the highway the car was choking / shaking. I have replaced the coils and spark plugs , which seemed to fix the issue for a month. few days ago i accelerated hard again and it went into limp mode and i am getting the codes above. Beforfe the limp mode I also got a code 29D9 Misfire at low tank fill level. prior and in addition the the codes above. Any suggestions? if it was the HPFP failing wouldnt I have issues with more than 1 cylinder?

[@tomkikkert489]

Did you find the problem? I have similar symptoms, including regular limp mode when fuel tank is nearly empty, particularly under throttle in corners. It only shows codes of misfires and injectors, but my guess is the HPFP or maybe even the LPFP.

Love your videos by the way thanks for all you do

[@dionysiostsiros7243]

Very insightful video! I have a 2008 325 cabrio (E93). An HPFP problem (with slow starts and increased fuel consumption) was diagnosed yesterday in a BMW authorised service unit in Greece, Europe. The HPFP was replaced together with NOX sensor back in 2012 at 32,000 Km. Now the car has 153,000 Km. In your video you mention that HFPF comes with a guarantee for 10 years or 120,000 miles, whichever comes first. Do you know whether this guarantee also stand for Europe? BMW authorised repair unit never mentioned that and budgeted the replacement works at 1,500 euros... What should I do?

[@robertroden72]

Hey sir I changed out my mosfets and now I get the code 2fbc .. I seen they was 8 mosfets that 644B so I changed all out to 14n30 and now i replaced the other 2 back to 644B and still the same cranks then codes and shuts off fans gets really high rpm

My N54 has 190k miles it doesn't have long cranks but has a hard time idling on a cold start but recently it acts like a misfire but i just replaced all my coils and spark plugs so i am hoping its the fuel pump behind the passenger under the seat. i already replaced the other side but i also have it set to idle at 750rpm its mhd stage 2 if someone could please tell me what it would be please do. also before the car would just act like its misfiring it would start to shake if you gave it too much throttle but if i turned the car off and right back on i could drive it again fine unless i floor it again. my code would say fuel cut off thats it

[@MrPickles_l]

If Coils and Spark Plugs were replaced- have you considered faulty Fuel Injectors. If the Injectors are ground side switched- you could have a bad DME also known as PCM.

Cristian it took me months diagnosing a 30ff and turned out to be bOoSt solenoids. Don't use eBay like I did. Use Fpceuro or similar

30ff could be a dozen things. It's a low boost code. Could be boost sylenoids, shoddy vacuum lines, chargepipe seal/crack, intercooler connection leak, or worn out wastegates.

[@Theory1k]

Ive always had this code but its so random, last time i did a small 3rd gear pull and peaked at 12.9 psi (not tuned) and i let the gar get to about 6000 rpm, so i dont think i have a boost leak, besides i have a doc race charge pipe and i just replaced my vacuum lines but the issue keeps coming back. Its weird how if i turn the car off anf turn it back on the car runs normally but as soon as i get into 4th gear and i get over 3500 rpm it gives me the half engine light and when i read the code on mhd its always 30ff.
