-low RPM
-knocks and stutters
-check engine light
-various codes for misfires
and a STRONG smell of gas...then it starts and when warm it runs.
I did some pre-process of elimination work before I took in into mini,and gave them a laundry list on stuff I needed checked (including injectors) and they determined it was HPFP "issues" saying it needed replacement, but would I get the strong gas smell with a failing HPFP?
My new (to me) mini countryman is having trouble starting and running at half engine power.
2EFE Combustion misfires, several cylinders: detected
2BEE High Pressure fuel, plausibility, cold start: pressure too low
2EFF Cylinder 1 combustion misfires detected
2F01 Cylinder 3 combustion misfires detected
2EE2 Combustion misfiring, several cylinders: damaging exhaust gas after start sequence
2EE6 Combustion misfiring, cylinder 1: damaging exhaust gas after start sequence
2EEC Combustion misfiring, cylinder 3: damaging exhaust gas after start sequence
These are the codes that are coming up after I cleared the first engine light that was on. This issues has happen a few times and is very on and off. The car will start and run fine one minute and the next be at half power.
@interjectedGT i noticed you posted that mini covers the high pressure fuel valve but not certain if thats the issue.
Does anyone know if the extended warranty includes 2011+ models with the N18? I'll call the dealer tomorrow to confirm but my 2011 had the HPFP replaced in 2015 at 45,000 miles by the original owner.
Its now just over 70,000 miles and failed again with the standard multiple cylinder misfires at startup after sitting for a while and temporary limp mode. The fuel pressure on the torque app confirmed this is almost certainly the issue with the P15DF code and less than 100psi of fuel pressure during startup.
The car has been such a money pit the last few months I might end up ditching it seeing that the parts alone are $1200.
I'll jump in here too...I have an '09 R55 JCW with 189K on it. Looks and drives like new, even my local MINI specialist (Auto4N in Cincinnati) said they couldn't believe how nice the car is for the miles on it. Anyway, I've had a similar issue, but mine starts up fine, idles a little rough, but now under acceleration it starts cutting out. I was getting a CEL for the knock sensor so I replaced that, but it's still doing it. It goes into limp mode then back out, then back to limp, then out...but isn't giving me any other codes. I have a Scangauge that also indicates no codes. Sounds similar to some of the HPFP symptoms here but not identical. Before investing $$$ in a pump, I want to make sure that's it. My car is not included in the recall because it's a JCW and because of the mileage. All of the major service items have been replaced including the timing chain at 163K and the turbo at 176K.
Will the Torque App or Dash Command apps discover codes that my Scangauge won't?
Since this is a recall and error on mini's part, can i bring my 2010 mcs to the mini service center to diagnosis if i need a new hpfp for free ? I hate paying them to check something all the time.
My dealer required me to authorize a $100 or so diagnostic fee, which was not charged because the pump was bad and covered. If it wasn't the pump I would have had to pay the $100 in theory.
So I am 99.9% sure my hpfp is going cause of the listed symptoms above... I brought it to my local dealership and said everything is fine and they did an pull and said it pulled hard. I'm on a stage 2 manic tune and wondering if they wont be able to find the problem because of the tune on the software. Thanks for the help in advance.
They need to see the codes from the computer read out. Otherwise they aren't going to do HPFP. The tune probably won't hide the codes showing up, but that's a question for the tuner.
definitely HPFP failure. You should also have a 'half CEL'
~80psi is the pressure from the primary pump to the HPFP.. so if that is all you are seeing, its dead.
*Mine failed the same way. Dealer replaced it under warranty no questions, once i gave them the ECU code and they verified the fuel rail pressure themselves. Other than the fuse blowing.. there is no reason you only have 80psi on the fuel rail.
I have a scanguage II and i tried to see my fuel rail pressure and it didnt show up. this problem started when i blew my thermostat and my ignition coil doing a pull.
I wanted to give an update since my car is back together and I've been driving it for a little while now.
Before, I could replicate my heat soak problem with the HPFP at will. I knew when it would happen and pretty sure I knew why.
After getting it back on the road I can now say that things are WAY better than before. I've only had one short problem with heat soak/no fuel pressure since putting the car back together.
Did the heat barrier help and is it preventing the bypass solenoid from acting up?
I can't say for sure, but that's the only change I made that I can think would've made a difference.
I did speak with my dealer about warranty and why the 2010 models were skipped, and MINI offered to pay 50% of the repair though. Which is still ridiculous. So I'm waiting until I absolutely need it.
One final update to this mystery, with a possible discovery of the cause.
Earlier this year I decided it was time for a different tune. I sold my Access Port and had a Manic Stage 2 tune installed.
I haven't had a single episode of low fuel pressure since.
Coincidence?
Or was it something tied to the Acess Port?
I may have an issue with my high pressure fuel pump. We've only had the car about a month and we've had problems.
its a 2010 Clubman S, with the N18 engine. We've had intermittent vanos fault codes and the car has reduced power, that was booked in for end of November.
Today the Mrs rings me in a flap, as she's broken down on a country lane. I've checked and the fault codes were 002BE9 and 002C01, which when looking up, all point to the HPFP.
i cleared the codes and the car ran, I made it 1 mile down the road before it started to lose power and eventually died. It's been towed home and I've put some fuel in it, but it will not start. It initially ran, but would struggle to maintain revs and then stall. Now it just turns over and won't start.
At the moment, there are no fault codes displayed. I've used Torque and Carly App for Android.
I've attached a screen shot of the fault codes.
How do you check the fuel pressure using the torque app? I couldn't find the option for fuel rail pressure
