Hi everyone,


i´ve been fighting this problem for a while. I´ve been reading a lots of threads regarding this issue with no specific solution.
Symptoms are hesitation/rough idle, stalling when on low rev and uphill, ratchering noise when stalling. Is an 2008 MCS r56 (Automatic)
CEL is on with the following codes:

DME
2783 combustion misfires several cyl.
277B combustion misfires several cyl.
277F combustion misfires several cyl.
2773 combustion misfires several cyl.

2DCA fuel shutoff due to super knocking cyl.4
2DCB
2DCC
2D52

Does anyone knows what this is? need help, desperate and frustrated.

Any help would be very appreciated.

Thanks

 

My guess would be HPFP..

 

But i´m not getting any codes for HPFP and if it is bad then i suppose to get a code for that right?

 

I was guessing based on the mis-fire codes. The HPFP is a common failure on these cars..

 

i´ve been reading a lots of thread about this issue and when somebody is having a HPFP problem there is always a code but maybe i haven´t read all the threads out there.
I just don´t want to spend the money in a HPFP if that is not the issue because as you know HPFP´s are not cheap.

 

Whats the oil reading on the dipstick? Is it using oil? Sounds a little like my wife's 2010 that ended up being the timing chain tensioner and guides.

 

Actually oil is good, in fact I added a half of liter or half bottle of oil two weeks ago after 1500 miles of driving the car. I dont know if half of bottle is good for 1500 miles. Hope it is.

Anyone one with more ideas what this could be?

 

I have similar issue. I brought it to the dealership because the car will not start. Prior to that, the same symptoms existed then finally got CEL P0300 a misfire on multiple cyclinders. Since getting the car (codes)read, I just parked it and left it. When I finally towed it to the dealer, the car would not start. Definitely get it checked soon. I just got my car back today after declining the service and saw that dealer replaced HPFP as maintenance thinking it was the cause of my car not starting. It is not, they are saying it's no compression. Honestly do not know what to believe, they ask to further diagnose for an additional $500-$600. I declined and will seek another route or independent shop. At this point, I don't care for this car since I ordered a new Audi A3 Sedan. Below is what was done during diagnostic. At least I got a free HPFP. Good luck.

 

Well, i´m not getting this CEL P0300, all i´m getting is just those codes that wrote in my first post but i will try to get this weekend a compression test for my cylinders and reply back. RumpyPumpy once you take it to a independent shop let us know what happen.

 

rumpy,

Have you ever had a carbon cleaning (walnut blasting)? If the intake valve are caked up bad enough you will get low compression and it will run like crap. Typically ~$400 job at an independent shop.

 

Have you checked your Sparkplugs, Plug leads and Coil Pack terminals (for corrosion) ?


Have you checked your fuel filter ? If all the above are OK I would bite the bullet be dropping it into a dealership and getting it seen to. At least confirm if the HPFP is at fault or what other issue may be the cause.

 

@sub3622 - I will definitely come back to this thread once I get it to an independent shop. good luck to us all.

@cerenkov - yes i am familiar after being in this forum. I must have read so much threads on general issues. i've learned a lot. this is also my thought, it could be carbon build up but when the time comes, and if it is really just this, and i hope; i'll have it cleaned.

@milpol - Mini service already checked spark plugs, plus and coils. no dice according to them. wanted $600-ish to further diagnose. fuel filter is something that was not mentioned by Mini service. HPFP as mentioned on that screenshot was replaced for free. i just ended up paying about $159.99 (initial diagnostic).

The Mini is on my driveway now and looks like the battery is drained completely. The tow trunk had to jump it to disengage P to Neutral.

 

It's funny how you had to pay $159 diagnosis fee and it didn't fix the problem. Glad that they covered the HPFP under warrantee. If they are just swapping parts that would get really expensive, really fast.

 

I know this is "way out there", but how old is your battery?

 

And, HPFP failure will not set any HPFP codes. HPFP is not directly monitored, as far as I know. Multiple misfires on all cylinders, to me, would indicate either a fuel or spark problem, not specific to any one cylinder. A compression test is required in order to verify the piston rings and valves/seats mechanical integrity.

 

There are several different issues discussed above. A 'random' misfire can indicate a number of failures, versus a misfire in a specific cylinder. The random misfire codes can be indicative of a failing HPFP, even if there isn't a fuel pump code. The pump codes are a little more sluggish to show up than misfire codes. If you have terrible carbon buildup, you can get random misfire codes so that can also be the culprit. If you have codes for a specific cylinder (P0301, P0302, etc) without random misfire codes, It's more likely an ignition problem like plugs or coils.

 

FWIW, I had P2880 error code (High Press System Min) that had prompted the dealer to replace HPFP at 67K miles on my '08 MCS.

When my cyl 4 exhaust valves disintegrated last year, the symptom was rough running on three cylinders, with multiple misfire codes on all cylinders (P030*, 27**, etc). Not to scare OP unnecessarily, but what he describes reads painfully familiar.

Agree on the need for compression test.

Hi:
So my car had those codes this spring and a mechanic (not MINI) told me I needed a new motor. MINI checked it out shortly thereafter and the codes had been cleared so they weren't able to evaluate the issue. Now it's running rough on start, hesitating, stalled last night on a hill (very unusual) and today it went into low power mode. It's at the dealer now. I have to ask: how much did fixing this issue set you back? Sounds like another quirky MINI thing... thanks in advance.

 

I’m curious, my fiancé’s n16 is having the same issues. What was the eventual cause of your problem? Thanks in advance

 

First of what codes are you getting? This will help us help you. Don’t just start throwing money at it without giving us some codes.

 

Hi, I’m getting a handful...

p0300
p0301
p0302
p0304
2775
27BD
2771
27BB
27BA
2781
2C8D
27BE
2779

And it currently won’t turn over. Started until it got parked in the garage for a few days

 

This is after replacing 4 coils and plugs.

 

I have videos of running but can’t seem to upload.
