Upon starting my car to leave work yesterday I got a check engine light. I pulled the codes and I have P15DF (High Pressure Fuel Pump: Cold Start Pressure Low) and a Misfire on Cylinder 2. My car is a 2011 MCS with 51,000 miles, so it's out of warranty and the extended HPFP warranty does not apply. Anyone with any experience with these two codes together? Could it be dirty injectors, or do you think it's definitely the HPFP? I've tried searching but couldn't find this combo of errors. I can replace the HPFP myself, but I would like to make sure that's the problem before I start throwing parts at it. Any help you can offer is MUCH appreciated.

 

Stupid question, but why does the extended HPFP warranty not apply? Does it not apply to your vehicle model year??

At 51K miles, perhaps the dealership might goodwill the repair if that's the case.

Sorry I can't be any help with the diagnosis.

 

Well if I read this correct they consider it a emissions related item. See if you can get it covered under that. Did you buy your MINI new? At this dealer? Maybe another dealer can help or call MINI direct to see if you can get help. Good luck.

 

I had the same code pop up today and P0087 as well. At this point, just going to fix the MINI and enjoy it since everything is getting replaced and we'll see if I need to do a walnut blast too.

 

THE HPFP HAS IT'S OWN WARRANTY AND WILL BE COVERED. already had it done on my '11 this year no questions asked.

 

What dealer? Give me the number please so I can show my dealer since I'm out of warranty thanks!

Mine is an '11 too but they said it's not covered for the N18.

 

I had the EXACT issue happen to me today, but my 11 MCS has 57,000 miles. Same codes are showing up-- OP what was your resolution to the issue? Did you replace the HPFP? Any help would be appreciated!

Get your car to the dealer ASAP. HPFP failure is incipient. I had similar codes and waited out of necessity. The fuel pump died completely half way through a 1,200 mile trip. It's a very easy and quick repair.

 

I'm having the same issues with my 2012 Mini Cooper S. Misfire in 2 and Low pressure in fuel rail. P0087 and P15df I'm in CA and we have a 7 year 70k warrant for emissions. The HPFP is listed and covered under that warranty. I just spoke to 2 mini dealers today. Check your owners manual, hopefully you are covered and it will save you $1000-1500. Im setting up my appointment tomorrow.

 

My HPFP was going bad, confirmed today. Mini replaced in under warranty per emissions warranty. In CA we have a standard 7 year 70k miles emissions warranty, it is about a 1500$ fix.

 

Good to know! I see some n18 2011 are covered under the extended 100k warranty but had no idea that hpfp also fall under the CA emission warranty.
