BMW N55 High Pressure Fuel Pump Replacement F10 535i

[@MrCoverzero]

Great vid. Straight to the point without a useless monologue or obnoxious music.

[@Industrial_Mechanic]

Hi.Thank you for the video. How is the remanufactured pump doing two years later?

[@正朱-d8o]

5 mins video=50 mins work for the one who make it first time 😅

[@mckazok]

It took longer 😒

[@bmw_shenanigans2912]

Yea that shi gon take a lot longer 😭

[@gyorgischwartz]

More like 2-4 hours depending on the condition of everything. Shit breaks on these too

[@jeffwonchuloh]

Could u list up what kinds of tools u used please? 🙏 Ill try to do it myself in the parking lot. Also should I disconnect batterry before fix?

[@lillouie9738]

How did you get the wire harness off that sits right behind the high pressure fuel pump?

[@frankplayz1462]

Great video. My car is saying fuel supply. Full drive performance not available then car dies and wint run for maybe an hour. I changed the low pressure fuel pump about a month ago. Everything was fine now same issue is back. Any idea of what it could be? Thank's

[@mckazok]

It would be helpful to get fuel pressure reading for both sides.

[@gilgonzalez5902]

Your problem is 100% the fuel control module located in the trunk under the carpet. Once it heats up it will stop working hence no fuel delivery. When the vehicle is cold it will run perfectly only when it warms up after about an hour. Common issue, the control module takes 5 minutes to replace but it needs to be coded to the vehicle.

[@MichaelMorrow-c4n]

I have a 13 IM 535i BMW, start the car let it out for about 30 minutes and it falls dead and won’t restart until about 15 minutes later like something has to cool off to start. Could it possibly be the fuel pump ? I replaced the fuel pressure sensor and it’s doing the same thing 😢

Ekpm fuel pump module is overheating

[@nes286]

Hi, great video. Can you recommend a good company that remanufactures HPFP that is OEM? On a tight budget. Where did you purchase your replacement?

[@mckazok]

I was leaning towards amazon refurbished pumps at first but the amount of work involved and being such a crucial part forced me to get it from FCP.

[@gilgonzalez5902]

It only costs $300 from FCP EURO for the whole kit OEM pump. This hpfp is not expensive like the N54 pump.

[@mckazok]

@@gilgonzalez5902 Two years ago I paid almost $800 for this pump, which is now over $1K. The $300 pump you are referring to is the newer style smaller unit.

[@hima-iv5mc]

@@mckazokmine is a 2013 535i 10/2012 build date do i have the newer or older style?

[@nes286]

Hi I have a 2012 BMW X5 xdrive35i. I replaced my throttle body and my HPFP. The car throwing fault code P15DF. I also have the Engine alert: Engine malfunction reduced power Chassis stabilization malfunction DBC malfunction drive carefully. Thank you or your subscribers for any advice…

[@jrey240]

Do you remember what size Allen key you used to get the 3 bolts out?

[@orangindonesiatinggaldiame6420]

Great video. Questions. Where is the low pressure sensor located? Thanks

[@mckazok]

At 2:30 I'm pulling the fuel feed line to hpfp by holding the low pressure fuel sensor.

[@johnvargas997]

Good video. Do you happen to know the torque specs ? Thank you in advance.

[@mckazok]

I don't know the torque specs, did it all by feel.

[@duchaihuynh9508]

Thanks for showing you are awesome.

[@topdogg3891]

What’s that line called that u circled with the green, broke mines trying to get to the high pressure fuel pump

[@mckazok]

11657588771 vacuum line for waste gate control

[@BulldxgsMotorworks]

did you not prime the fuel pump after? my car won’t run properly now that i changed the hpfp. i did everything correctly

[@mckazok]

LPFP ran a little longer the first time the car was on and built up pressure in the system. I also missed one of the connectors to the ECU, so it ended up being primed while trying to start. But no running issues afterwards.

[@BulldxgsMotorworks]

@@mckazok do you have any recommendations on what i should do? should i re track everything and take it apart part by part to see if everything’s correct. i don’t have the right tool to prime the pump so idk what to do

[@mckazok]

If it runs, even barely, you are past priming stage. Something else needs to be fixed. Any CEL yet?

[@mckazok]

I had a rough running issue right after replacing 100k old spark plugs with a new set. The only thing that resolved the issue was clearing adaptations.

[@BulldxgsMotorworks]

@@mckazok what does that mean?. it takes a couple seconds while cranking to fully start, then i get a transmission malfunction code

[@diazrd4016]

Great video. What type of HPFP you put aftermarket or genuine and if is aftermarket what you recomendé

[@mckazok]

I used a remanufactured original from fcp. I know it's tempting to get aftermarkets from ebay\amazon given the price difference, but after reading some reviews on how long those units last and the fact that I can't just change it on the side of the road, I decided to pay the price.

[@daslothmc3910]

I constantly got rail pressure: fixed errors so I changed the hpfp w my friend and the car was fine but not even a week later it started doing the same shit and the only thing I can think of is the hpfp again since everything else in the fuel system works fine, I even changed the injectors. 600 down the drain now I gotta buy another one

[@stephanelouvet1113]

Did you check you high pressure fuel sensor ? It's attached at the end of the high pressure rail. After cylinder 6.

[@samalsabiry3540]

Amazing 👍

[@loyal9765]

can someone send me the link the high pressure fuel pump

[@AndreGTunechI]

Hey I have a question

[@SmileIso]

What was the symtoms of your car leading to HPFP replacement

[@mckazok]

I had 3 symptoms. 1-engine would take around 3 seconds to start 2-if i drive after first start, it's would run in low power mode, limp?, unless I stop and restart engine. It would also log low rail pressure error. 3-after a hard pull, it would go into limp again.

[@SmileIso]

@@mckazok Ok my symptoms are different. I have air mass low issue (code 102002) and drivetrain malfunction code 120308 when pulling hard. The Drivetrain malfunction come systematically, and the code is related to low boost. I wonder whether the 2 code are related, low mass air flow and low boost.

[@mckazok]

@@SmileIso sounds like a leak

[@SmileIso]

@@mckazok yesterday I replaced my intake manifold gasket, DME gasket and also throttle body gasket and also cleaned my intake valves. I immediately felt that the car is more responsive, more powerful, but I didn't pulled it hard yet to check if low boost error will come

[@SmileIso]

The low boos error came again. Now am thinking about MAP sensor on the intake pipe. The reading was not stable last time I connected ISTA D. There were deviation with ambiant pressure (2,7 hPA). It is within tolerance (+ - 25 hPA) but it was toggling

[@N5XBEVST]

What year is this car?

[@mckazok]

2011

[@claudiozils5882]

Estou com um código de falha 1f0525 numa 535i BMW

[@gian-lucakaja8015]

Is it the same on the 335i?

[@gian-lucakaja8015]

I only need to change the railpressure sensor

[@mckazok]

@@gian-lucakaja8015 luckily manifold doesn't need to come off for rail pressure sensor

[@sidpryor6469]

Hardest part is getting wire harness off of air manifold. Not shown here

[@mckazok]

I agree, it's a straightforward yet the most difficult step anytime intake manifold comes off. I changed the starter about a year ago and hated it.
