Huge high pressure fuel pump wear out. Lots of metal fileings in pump, injectors, sensor, valve, pipelines, fuel tank. Symptoms: cranks, but does not start car. Diagnostics shows low pressure on high pressure fuel ramp(HPFR) while starting.

I cant get my fuel pump fully out... It only gets out 1cm or so but not all the way out. I have tried to pull it out but it wont move. The screw on the back is also loose and removed. I tried with the special tool also.
Hi. I beleave the sprocket is still tight on axel. Take a look on my other videos, you will understand. Did you use special tool to release pumps sprocket?
@@jonasjo202 Yes, but i didnt hear the "click" everyone talks about. I just started trying to pull it out and it got a little more out, but its still very tight...
Sometimes there is one more small very long bolt from the gearbox side.
I also misread the title... Thought it said n47 (the one i have), but it might be almost the same thing
My HPFP failed on my 2014 535d xdrive, did you have to replace injectors? Remove fuel tank and all lines ? To be cleaned or replaced? BMW told me only way to fix it is to replace everything from fuel tank to injectors. I don't believe them tho lol I saw there's an aftermarket filter that can be installed to filter all metal out before it reaches hpfp
Hi. We usually replace new HPF pump and new injectors by BOCSH, giving old stuff back to remanufacturing. Clean very well all lines and tank. It's not necessary to take them off. After all change filter one again or twice. Good luck.
@@jonasjo202 can I hire you ?
@@jameskelly9510 ok, sure, why not 🤣🤣🤣🤣. I'm joking! I'm already hired. Thanks for invite! 😄👍
@@jonasjo202 lol I wish you were in America lol. Have you needed to do timing chains when the pump gos?I read something on forms talking about it but wasn't very clear. & My primary fuel filter showed some small amounts of metal but when I pulled the filter on the actual pump no metal was in it? Have you seen that before? I still need to pull rail and everything apart. It has the DDE fault when I run Ista
@@jameskelly9510 some time ago I was thinking to visit America 😄, but not now... When changing pump does not need to do anything with chain. It needs only a special tool to remove it. Maby next week I'll make video about that tool. Yeah, the metal pieces are most important to remove.
Actual Rail pressure on my N47 E91 is from 260 to 270 on idle. Is it normal? As the car starts fine and drives fine the only code stored on DME is 4BDA fuel presupply pressure control but no engine warning light or message. Does this mean weak pump? Thank you very much and really appreciate your help to everybody 🥰
270- 320 bar is normal pressure. That code means weak pre-supply pressure. Take a look on diagnostics, it should read near 4 bar. If it's more, than bad sensor. If it's less, then weak pump in tank.
@@jonasjo202live data presupply pressure shows 210 bar witch is really high. So now i have to change the sensor that came with the hose before the pump HP and will let you know what will happen. 😀 thanks again
@@Winter1256 yeah, pre-supply sensor is fitted on rubber pipe before hpfp pump.
Hi my pump is reading 3.2 bar is that too low or is it still acceptable?
How many km does this engine have ? Also what can you do to prevent this to happen ?
Hi. I do not remember how much KM, but you must bleed fuel system after filter change.
Hello, can i open the pump on the engine? Without remove pump of the engine...i found metal on my injector...
Hi. Yes of course, I did it many times...
@@jonasjo202 is it difficult to remove the pump without remove the engine of the car? N57 f10
No. You need to remove inlet collector, some wireing and you can see the pump. Then you need special removing tool to separate sprocket from shaft.
@@jonasjo202 to examine the pump, simply remove the four screws on the top of the pump?

@@Mymerguez yes. Be careful, it's spring loaded. Then pull out piston, sometimes it's stuck.
I got the same issue garage quoted £2.000 for a new pump ,its a f10 530d
Yeah, expensive repairs. Does it runs fine now?
@@jonasjo202 its in garage at the moment warranty company declined repair
@@Fordmk1 0h shit, these pumps are weak engine parts, many failed.
Hey man. I'm thinking I may be in the same boat your in. Even tho they put a recall out, I cant afford to wait. Anyway, I'm getting low pressure to the fuel rail. Is this something similar to any symptoms you had. My car was fine, then just gave me a drivetrain warning and died.
Yeah, that's the symptoms are...instant death and loss of fuel pressure. Good luck with yours, fell free to ask any question...
@@jonasjo202 thanks for the reply. I think I will take apart a few pieces and see if I have material floating in there before I contact bmw. I'm at 70k Miles but I hear they will cover the hpfp upto 125k
@@jonasjo202 took the metering sensor off. Had some sand in there. Getting it towed to bmw today.
@@azneau28 hi. I wish you best luck over there 😂👍
@@azneau28 do it yourself man it’s easy to replace! Why bmw?
Where are you located
Lithuania
Hi i have a same problem i wanna repair kit
There are no repair kits, only remanufactured by Bosch.
@@jonasjo202 Have you seen remanufactored version, is it actually solve the problem? My car have same problem now. I bought it few days ago and it covered with warranty. I'm currently deciding should I keep the car or get it back to dealer because this seems to me like can happen anytime after replacement, because of design defect.
@@AlexeyDubkov hi. I use remanufactured whole pump. They seems last long like new. I have many satisfied customers, no returned back.
@@jonasjo202 The new lasted 33k miles :D And required full fuel system replacement for around $20k. So.. I really hope remanufactured will live much longer.
@@AlexeyDubkov these pumps usually dies around 150 000 - 200 000km, depends on fuel and filter quality.
