Hi
This car came to me after "new" parts we're fitted, but did not fixed the problem...
Now, was this misdiagnosed, or...
It is a long video, and yes, I could have made it 10 minutes long, but thought would be interesting for you to follow me through the hurdles and mistakes...
Follow me on this video, to find out what was the problem and how to resolve it.
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching! - Авто та транспорт
I really look forward to seeing your videos, I especially like the fact you don’t edit it to show you just simply diagnosed it with out the odd wrong direction & I’ll explain why , we all have problem jobs and seeing videos with people just seemingly diagnosed with no fuss don’t give the viewer a real world experience.
Personally have made many mistakes over the years trying to get to the bottom of problems ( and continue to do so ) every day is a school day and we learn by mistakes ... or stepping stone to Succeed as I like to call them
Thanks for taking time to share Louis
😊
To be honest, I also have not much patience to edit...😋
But I totally understand and agree with you!
Thank you for watching and for your comment!

Amazing journey to get this repaired!
Never seen a petrol engine with such a fuel pump mounted to the cylinder head. Very interesting.
Always remember to check basics such as oil level. I was working on some car with engine management problems and it was tricky. Eventually I decided to look at dip stick. There was hardly any oil in it and one cylinder already very low compression!
I missed if and when you checked live date for the coolant temperature, especially as it was a fault that occurred only when engine was cold.
Main handycap for you was doing this with a mechanical fuel pressure gauge. Hope Santa is going to bring one for you!
😊
Santa is usually not that generous... lol
But yes, I need to get one...
Thank you for watching and for your comment, appreciated!

Great video. Thanks for sharing . You have the tech and the knowledge. imagine the garage . "It cant be the pump we fitted a new one"
Pretty much...😊

Great work Bro👍
Really if this type of fault is not attacked properly, there's a good chance of replacing a pile of part's while troubleshooting😉
There are many situations where we Tech's take a deep breath & say "Boy I don't have the right tool for this job" it happens😉
But you made the right call & fixed it, which is important👍

Had the same, same problem! I didn't try to guess. I told the owner to replace the low + high pressure pump and pressure sensor. The mini had done 200k+miles. It worked after the replacement. Lucky I guess? I like what you do and the recordings. A lot learned. Am at Nairobi Kenya.
👍👍👍
Thanks, for watching and for your comment!
Excellent video well done. Watched as my '11 R56 had the yellow check engine / low power light on though has now disappeared the following day... The engine was running perfectly fine despite the check light so will suspect the pump being a bit worn due to millage at 98K.
😊
👍👍👍
If I were the garage owner who fitted the pump I would not be a happy chappy. All that extra work and cost because the replacement was a dud. What's that old saying "The bitterness of poor quality remains long after the sweet taste of low price is forgotten". Top diag again Luis.
Agree... Nice saying... think first time I heard it...😊
👍👍👍
Brilliant work Louis, thank you for all your hard work 🤗
Thanks Jay... for watching and for your comment!

well there you go, demonstrating once again that intuition and experience can be just as useful as testing, good call, think how much time it would have saved if you had just thought to check the oil at the start, .. something we always used to do when we had the good old carbs, .. anyway good call .. and interesting problem.
Absolutely... sometimes we regret no starting from the other end...lol
Thanks, for watching and for your comment!

This video saved my mini, i was about to set it on fire 😂. Bro your hard work helped me so much. My mini wasnt giving any codes but pressure was low. So i bite the bullet and changed hpf pump. Perfectly starts fine. Thanks 🙏🏼 to you
☺️
That's great!
👍👍👍
Gonna set mine on fire too man same problem here😂😂
☺️
My mini has started acting up about 2 months ago and it's off the road since while I slowly shotgun new parts into it hoping to fix the issue. The car is fine if driving with barely any throttle but if you give it any good throttle it makes a machine gun popping noise from the exhaust and it feels like misfires and power cuts.
I've replaced the hpfp twice, lpfp, coils, plugs, vanos solenoid, new maf, new map sensor, new vacuum lines, new pcv hoses, new diverter valve and a new valve cover. Throttle body is less than 6 months old, likewise the water pump, aux waterpump, waterpipe, friction wheel, thermostat, turbo and lines.
I was told the main sender could be the issue and others say timing...Im not hearing any chain rattle and the guides look fine too. I really wish there were people who diagnose like this in my area...because I am so tired of throwing money at this car at this point. Ive sank 3-4 times more than what I paid for the car over the past 2 years and I love how it drives when it wants to cooperate but Im getting to the point where Im ultimately going to end up parting it out if its not the sender....
@Raymo2u
😬
The timing can be easily checked by scoping it... I have videos for that, search my channel...
Everything else can be checked by looking at live data, etc...
As for the high pressure fuel pump, hope you have installed a genuine pump... as the aftermarket ones can be a hit and miss, and if you are not using a scan tool and live data, it can lead you in the wrong direction...
Diagnose, test and replace the faulty parts.
Just throwing parts with the hope that it will fix it, can become expensive very quickly... as you know...
👍👍👍👍
Good job Luis as always, if u did check the oil level earlyer u should find also earlyer the reason of this trouble, whatever we are all learning and learning every day, thanks Luis for all ur videos. ur Algerian follower was here :-)
That's correct...
But the fact that the car just had a new timing chain, oil change, and the "pump", it never lead me to check it...🤷♂️
Well, got there in the end...😋
Thank you for watching and for your comment!
@@LMAutoRepairs Another question Luis, do u have any idea why the faulty fuel pump work fine when the car is worm?
@@KaKi_AutoDiag
Has I have already answered on other comments... the only thing I can think about, is that the temperature and expansion of materials, would seal something or whatever... I never opened the old pump... so, can't really tell...
👍👍
@@LMAutoRepairs What made me wonder even more is, why it runs good even when cold when you disconect that pressure regulator (fuel metering valve). Obviouslly car run with default values at that point, and everything is good. Would be nice to see duty cicle for the regulator once the connector is off.
I kinda did show... the ecu just stops cycling the valve once fails to achieve the correct pressure... it is on the video...
Thank you for watching!
Luis, thanks for the info/video enjoyable as always and u are AWESOME. cheeeeers
Thanks!
👍👍👍
Great diag! You should get a current clamp you can hook up to your scope, so you can check the current waveform in the pressure regulator. Perhaps there was a difference between cold and hot, if it was stuck when cold or something like this.
I do have a clamp... Just never thought about that...
I believe was just the temperature and expansion of the materials, that was making the pump to pump slightly better perhaps...
Who knows...🤷♂️
Thank you for watching and for your comment!
Too good to see sm challenging videos bro ... Like u does .. and likes ur words that ohh dear .. 😂
😊👍👍👍
Thank you for watching and for your comment!
great video enjoy it watch it two time , like the fact you keep the mistakes i gain from them! question could fuel trim have help?
Yes and no...
Due to the low fuel pressure the trims would most likely be a bit all over the place...
Would however show something wrong with the mixture...😊

Thank you for another great video!!!

Amazing work
😊

Another great video 👍
Thanks!

The reason the pump start to work when the engine is warm is because the pump is filled with its own oil. That why there is a membrane on the bottom. You can measure the dept of the membrane with a vernier gauge. If its deaper than 26mm the pump lost to much oil and should be replaced. You can find a document about this in ista. Bmw/mini even have a special tool for measuring the dept with the pump still mounted on the engine.
👍👍👍
Mine measures about 27mm but seem to be getting good pressure to fuel rail on live data, having issues with the car hesitating and idling slightly rough, kinda seemed like a vacuum leak but smoke tested and no leaks.. don’t know if I should still suspect the pump or not
Have you scanned the car?
@@LMAutoRepairs hi, yeah I’ve scanned it but it’s not bringing up any fault codes unfortunately and no EML, the car is a Peugeot 207 GTI 175bhp but is the same engine as the Mini Cooper S N14
Live data... check live data...
Long video but very helpfull

Where did the "working" replacement high pressure fuel come from and how much did it cost? Thanks
Thank you for the grait working very helpfull
👍👍👍
This was excellent and worrying because we can't trust replacement parts. Everything seems to be made in China these days. A massive country. I'm surprised that there aren't quality control procedures. I'd have changed the sensor (wrongly) because I'd have thought it was the only thing getting warm. Changing the pump twice would have defeated me. Well done.
😊
Thanks, for watching and for your comment, appreciated!

Thank you! I've had the same exact problem and two aftermarket reman pumps were both not working and had driven me nuts. Mini/Bmw also threw the kitchen sink at this car and could not fix it either. About 4k in it now
😬
Hope you get it sorted...
Thank you for watching!
Having a similar issue, not as bad of a misfire on mine, when cold starting and then stalls, live data shows actual - 3.76 MPa and Set - 5.00 MPa. After a help with the throttle and running, at idle actual fluctuates between 4.48 & 5.18 MPa, revs up ok but misfires at idle, No engine lights but fault codes are 2C9E, 2D52, 2DCD, 2A92 & 2746. Just had walnut blasting done aswell to see if that was the problem
Nice one buddy
Thanks!
👍👍👍
amigo soy de chile, al final fue la bomba de alta presion (pump hpfp) ?? la cambiaste dos veces ?? tengo el mismo problema y ya compre una bomba hpfp y sigue con el mismo fallo 2880 y los parametros del escaner son los mismos cuando te fallaba
In France we call it the 1.6 thp motor, there are a always a problem with the fuel pump or the chain tensioner be careful with that to there is 3version of the chain tensioner if it's you're car put the V3 on it's take about 4bolts 30min 50pnd of torque for the chain tensioner and that's it do it before is to late
As I explained in the video, the had all that just weeks before...

Hi. Can you explain on n18 engine what is fuel nominal pressure value and fuel rail pressure PID difference or relation and how it works? Thank you
I had a similar problem to this on my 2011 Cooper S. It wasn't as bad as this and would run rough on cold startup and then trigger the engine light. I found someone on eBay who refurbishes the pumps so I sent it to him and fingers crossed it has been great since. He said the Chinese ones sold on eBay are just old pumps taken from scrapped cars which are cleaned and sold as new. A new genuine pump is £900+ so you can see why people buy the cheap ones.
Yes... they are expensive new...
Thank you for watching and for your comment!
Hi who refurbed it for you?
hi louis, great work you are doing i see most of your videos, which have helped me alot.... i have a r56 n18 engine.. with problems on the quantity valve... with the conector out i have 12v on orange wire and 0v on the white wire.... if i plug it in and start the car... i have permanent 12v on both wires... you think it may be the ecu??? thanks for the help
fuel pump presure is ok checked with insta... but the valve is always on 0% it will not work
Hi
Have you load tested the wires?
Have you scoped the signal?
Is the ecu actually trying to pulse the valve?
What pressure are you getting?
You need to test more things before blame the ecu...
👍👍👍
Great video once again !
I now you now tho i cant stress anough how much damage you can do running an engine with fuel contaminated oil ... The oil almost loses all its lubrication effects because of the petrol mixed in ... Even running it at idle for short periods is going to wear out all bearing and certainly the pistonsidewalls and pistonrings ...
I know... the good point was that the oil was new... 😋
Thank you for watching and for your comment!
Good one
👍👍👍
I’ve lost count of how many of the pumps I’ve fitted and the weird ways they can play up, went through the pain of buying what turned out to be poor quality new parts as well, they change slightly around 2010 on the n18 engine but are still rubbish I’ve done 7 in the last 3 months ish and the only place I buy now that I’ve never had an issue with is Neo brothers
Yes... they are problematic...

I am from Chile that is why I do not understand the language so much, in the end was the high pressure pump defective? did you change it twice? thanks for the video friend !!!!! regards!
I did not changed it twice...
Someone changed it first... but the "new" one that was fitted was also bad...
So, I had to replace it again...
That is what happens when you get cheap parts...
Yes, was the high pressure pump...
Thank you for watching!
Hey man i have a question I have a 2014 Honda civic si sedan im going 10mph and my vsa light turns on and it sounds weird
Scan the car, check live data and go from there... most likely an erratic reading from one of the speed sensors... but is just a guess...
Thank you for watching!
Im having the same problem. Whats the difference from fuel pump assembly and a high pressure fuel pump? And i keep getting that same beep as youre driving. 2010 mini s clubman doing same exact thing.
The fuel pump is the one in the fuel tank...
The high pressure fuel pump, as the name indicates, is the pump that increases the fuel pressure to higher values... in this case, the problematic one...☺️
👍👍👍
i'm reporting this Video, for discrimination against Crisps! Thansk for the video :))
😅
Thank you for watching!
👍👍👍
the main issue is just too expensive original parts and probably expensive repair labor costs that make poor quality cheap parts attractive to people. Also i get it how it can lead down the rabbit hole its not easy to think of sanity checks, but in this case verifying that the original pump starts to work when warmed up would have helped a lot.
😊
Indeed!
Thank you for watching and for your comment!

Question! I know this video is old but I have the same car with a similar issue. My fuel quantity control valve is always at 0%…. You said you checked for 12v under load, do you mean car on or just battery on? I don’t see 12v at all when I put a meter on it, but I don’t have a fancy pulse meter like that. I’ve been leaning towards a faulty ecu, I have continuity between the plug and ecu but no voltage. This is the only video I’ve seen with a similar description, figured It would be worth a shot to ask. Thanks!
The PWM signal from the ecu is too quick for a multimeter...
But again, and as per the video, if the ecu fails to build the pressure due to a faulty pump, will stop modulating the valve... so no voltage...
The scope will be able to show you right after start the engine, if the ecu is attempting to regulate the pressure...
Hope that helps...
Thank you for watching and for your comment!
Ok, gotya… my problem is I have too much pressure, not too little. Seems like nothing is being regulated and car is at maximum fuel pressure. I appreciate your response, thank you!!
Ah...
You never mentioned before that your issue was too much pressure...
Anyway, what is the pressure readings with the engine off?
Thinking about the possibility of the pressure sensor reading wrong...
What codes do you have on the ecu?
@@LMAutoRepairs with the car on at idle I have 10,000 kpa and only goes up if I drive it. Never thought to check pressure with it off. I’m no mechanic but it’s now on its 8th mechanic that cannot figure out the issue. I’ve replaced the hpfp and fuel rail sensor. Car chugs and stutters and has no power ltft and stuff at -25 all the time. And fuel quantity control v at 0%… also no codes no matter how hard I try to get one to come up.
What is the background of the car?
Have you bought it like that?
Eh my friend I got a question how many volts should I see on DVM when I check camshaft position sensor or crankshaft position sensor
If a 3 wire, a ground, and voltage (usually 5 volts)... the signal you can't really measure it with a multimeter... if is working OK, with the engine running, you might see 5 volts...
But for that you need a scope...
Thank you for watching and for your comment!

Are they branded a genuine high pressure pump like Siemens/bosch ?
This one if I recall correctly, was just a knock of aftermarket...
👍👍👍
How can tell a genuine one?
I changed the hpfp and it starts ups just fine again. But the check enigne light still comes on and the is fuel slightly dripping down the high pressure line even i tightened it correctly. Changed the line 6 months ago. Could this be the issue and I have to buy a new one again?
Possibly... what are the codes stored?
👍👍👍
@@LMAutoRepairs Bought a new line and it isn‘t dripping any more but Check engine light still comming up but only after full throttle.
@@LMAutoRepairs Also had it at the Bmw workshop before and they checked everything but couldn‘t find anything then the hpfp. Still cc-id 029
Check live data at full throttle, perhaps the pump is not building or maintaining the pressure...
Hi Luis, where abouts are you located? My in laws are having issues with their volvo V40. it keeps giving error that start button malfunctioned. However it does start sometimes. We have checked the ecu, ecm and the wiring and it seems all good, no corrosion and cant work out what might be causing it. If possible and youre not too far, maybe you could take a look? Will pay for the work.

I believe they have 2 circuits inside, just like the electric hand brake ones... and if both fail to make contact at the same time, they can trigger faults...
But you should be able to see that on live data...
