- Summery of information I have gathered about the commonly failing high pressure fuel pump for the Mini Cooper. Possibility for repair under circumstance of lost oil.
This is why I love the internet!!!
We all have (had) our little finds, and never cared to share… as the world goes round, we all keep inventing wheels over and over again…
Knowledge is to be shared and stored, no to be held back or kept a secret!
Thanks for sharing! Keep it up!! 👍🏼
Thanks, this helped me fix the identical pump from a Citroen C4 Grand Picasso with THP155 engine. Meanwhile, the replacement pump arrived but I've done several 1000km without any problems so I left the repaired pump in the engine. It may be important to know that the problem didn't disappear on the spot, but the repaired pump needed a little breaking in before all was back to normal. Thumbs up!
By breaking in what do you mean? This is my current situation I am in. Refurbed the pump reinstalled and thrown 2c01 code. Low pressure in hpfp. How did your car behave until it ran well and did it throw any codes?
@@leonard54321 The error code is unknown to me but obviously equivalent to P0087 in the Citroen world. After replacing the pump, the engine worked well straight away but some stuttering came back say during the first 100km. In don't remember if there were any error codes. After you fixed the pump, did you measure the distance to the diaphragm? Should be well below 20mm or else your repair failed in the first place.
@@janhemming2677 I did Jan Infact I had the opposite problem I used a hand pump vacuum on the diaphragm while installing the drive side. Ended up with a measurement of an increment below 12mm which equally worried me as that was it's minimum ultimate limit it could not be depressed anymore. After that I slowly unscrewed 3 screws until enough oil seeped out to create a 16mm dist from diaphragm to inner bell housing
I've been told by the main man himself Mr2tempos
Unfortunately I've upgraded safe proofed a lot of issues while cars been in garage for a couple of months
To me, it appears that the oil inside loses its viscosity causing the piston to lose its seal. Therefore, the bellows will not cycle its full-length witch will cause a decrease in fuel pressure. This is more likely caused by the extreme heat transferred from the head onto the pump. The pump acts as a heat sink from the head and takes in all the hat transferring it onto the oil inside. My 2 cents would be to change this oil every 3o-40k miles.
Just to share my experience...at the tine of my comment I replsced the oil by 0w20 sintetic ( same for auto motor) ..I dived the two parts in order of close it without any such little air'bubble.
So far, 12k kilometers roared.
btw, my pump is original from 2014..
Thank e for the information ,it was helpful.
Thank you for sharing
Great video
Thanks...super....angel👍♥️
very good master
What is the measurement of oil to put into the pump. Or do I fill to a certain level? Also how much lucus engine restore should I add? Thanks Leo
Thanks man for the video, it was helpful..
Hi Great Videos , what oil should i Use ?
Спасибо!
Nice photo of the bomb and its parts ...... presented at 5:16 minutes.
Bonsoir, quel type d'huile faut-il mettre dans la pompe ??
Здравствуйте где можно найти головку для откручивания плунжеров
Greetings from Mexico , I followed your steps and successfully y ended up with a good working pump. But I didnt change the seal, I couldn't find the part number , do you happen to have a part number? Im planning to take it apart nextime soon so I can change seal and orings .thank you for your tips.
Greetings from sweden did you follow his steps in the video and it worked? :) does it still work ?
Hi,
Does anyone tried to dive the pump into a contsiner with oil in order to guarantee no air inside the pimp before close it..
I was just wondering such method ..
I know it's a old comment but I was thinking the same. I'm going to try assembly with it submerged
@@Ryang1987Did you try submerged assembly?
pump in the bmw 1 series. peugeot rcz . mini. 207 , 208 , 308 and more
Hi, I see the post is old but I'm wondering if anyone can help me. I noticed the oil and fuel are mixing together... what should i do please 🙏
Hi could you tell me what grade of oil is used in these pumps ? Thanks
I've revived my pump from 17mm to 27mm on the diaphragm. My fuel pressure is now in the 700+psi @ idle. It idles smooth now. Not sure how long it's going to last but I'll try and provide updates when possible.
hows it going?
?
Hi not sure if you will see this reply but how to you check your high fuel pressure?
Hi SSA - Is this channel still active? Can you be contacted via other social media? I have a question about a damaged thermal compensator housing. TIA.
I measured it, it's 22mm. Should I repair it, or it's good? Can I use ATF oil (automatic transmission oil)?
22- normal ATF normal
Would this be cause of no crank ons chilly morning? I recently finished up replacing clutch and it sat for a week and when I tried to start there was nothing??
Yes, very possible. What happens is they lose prime when sitting over night.
OK ,tell me the best oil for the pump,specification ? i'm waiting you answer Thanks.
Says in the video best he could fide was atf or 80w90
Could You Show us the spring retract step plssss! I don’t understand when exactly should I retract de spring and how. Before or after the pump is closed?
they are in a citroen ds3 1.6 thp turbo petrol as well if it helps anyone.
Why don’t u tear down the solenoid and change the o rings on the fuel side? They dry out and don’t hold the proper amount of pressure. That’s where the fuel does it’s business
i cant find synthetic 80-90 oil, will mineral work?
If any one diagnosed his car and he pounds this code P0087 most probably this one its the issue the high pressure fuel pump
Dont forget to change an oil seal. If you dont do that, oil will leak into engine again.
I Need help? I have problem with porsche cayenne 4.8 turbo ? Full pump? Have you got video ?
What are the symptoms of a failing high pressure pump?? (N14 also).
Will run rough and sound like it's coming close to stalling. Might also get an engine light that's half coloured in
@@CocaiineNadex also high comsumption? Rich mixture??
Maybe unrelated ...heating of the engine??
I would suspect solenoid failure first !!
Hi, you are sure that a new pump has 13mm ?? I have measured a new pump with 22mm 🤷🏼♂️ .... thanks
BR Ronnie
I have a hpfp. I measured the diaphram, it's 22mm. Should I repair it?
@@grudgeholder6844 22- rood
@@mrboy3114 22 millimeters
@@grudgeholder6844 22-yes
@@mrboy3114 hahaha :) where is this conversation going? I just wonder, 22mm is good or bad. Should I repair it? 😁
O ring size pls
Man, are these pumps worth the hassle? Is maintaining the whole car worth your time?
So it's basically a two piston version of the old 3 piston pump used in the N54 and early N55s.
This video also misses vital steps which prevent this happening in the future, and prevent the pump being damaged... up to people whether they think it’s worth the risk or use a professional
There is no way to prevent it from happening again other than changing your oil often with the correct oil. You replace them when they wear out. That simple
@@chasechevy8933 Okay, But : What IS The Correct oil ?? Thank you.
@@kopronko ....No idea what goes in the pump itself. Those aren't designed to be serviced by the customer
@@chasechevy8933 are there any springs/piston replacement parts?
@@elieconstantine ....I'm sure there are but only shops with specialized tools do that kind of thing with any real reliable results
Whats he talking..u havent go clue lad
