I am really beginning to question my choices with the mini. the HPFP issues are challenging to say the least.
I had a small coolant leak that I wanted to fix before I got started on other projects. I bought a metal ECS housing and crossover pipe that I installed last weekend. While I had it all apart, I blasted the intake valves and installed new plugs. The plugs were a little crusty. After everything was buttoned back up, the car ran great for about one day. Fuel pressure was within spec. As noted in some previous post, I was having cold start up stumble and intermittent misfires. DTC codes suggested low fuel pressure. However, again, fuel pressure readings from a BMMV 3.0 indicated fuel pressure within spec.
I inspected the plugs again to see if they showed signs of misfire or bad fuel trim. After inspection, I cleared the codes and started the car. Ran fine for about an hour.
The car has gone into limp mode with the high-pressure fuel reading at about 85 psi. This is obviously a This is obviously a limp mode setting, as the expected fuel pressure is .6 MPA and the actual is .6 MPA or about 80 psi. Oddly it is not misfiring at that low psi. It runs and revs. However it is in limp mode and has no performance obviously. It is throwing the following two codes.

I believe the HPFP was replaced at a BMW dealership in April 2025. I do not know if the in tank filter has ever been replaced. Does anyone think it would be worth replacing the in tank filter and the fuel pressure sensor before dropping the money on the HPFP.

 

Based on your information, the problem seems to fit best with a faulty HPFP.

 

Thank you for the reply. I am just a cheap shade tree mechanic at heart. If I pull the trigger today on a new HPFP I may replace the sensor and filter, as I do not know if they have ever been replaced. The car is 13 years old with 130K. If the tank filter has never been changed it needs it.

Does anyone have any experience with hpfp-mini-cooper-rebuilt.com . They present a good game on their webpage, but I would like to find out about them before blindly sending $300-400HPFP-MINI-COOPER-REBUILT.COMHPFP-MINI-COOPER-REBUILT.COMHPFP-MINI-COOPER-REBUILT.COM

This continues to be very frustrating. I have worked on cars for approximately 46 years. I have a 1969 Corvette that is much easier to diagnose. I have a 2012 F250 that is easier to diagnose (most of the time). It seems as though we have only bought ONE thing with all of this technology...A few more miles to gallon, and nothing else. I am not discouraged about replacing parts at 130K. However, this thing had a HPFP in APRIL OF THIS YEAR. Three months before I bought it. At BMW prices, 5 months isn't long enough. I don't know how accurate carfax is or how easily it is user modified. However, if taken for truth the car has been fairly well maintained at Sandy Sansing BMW in Pensacola. Per CARFAX, it has had the following (along with regular oil changes):
4/18/25 Fuel Pump Replaced (HPFP or LPFP????????)
2/24/25 CAS module replaced
7/24/23 JBE Module replaced
11/22 VANOS replaced (1 or both????)
2/10 Turbo Feed Line replaced
5/21 Coils and O2 sensor replaced
1/20 Water pump replaced
5/18 Engine electronics checked
1/18 Spark plugs replaced
7/17 Vehicle electric checked
That is the stuff that could be quickly typed. There are a lot of oil changes and oddly, BMW loved to flush the brake fluid out often, like 4 times over the years. My F250 I have flushed the fluid once. After looking at the CARFAX and listening to other people, it appears to me that Mini Coopers are the MG's of today...A rolling POS of electrical and mechanical problems. I know it is a BMW, but it is tied to the Brits. Not trying to cast aspersions, but they can't seem to build a very reliable vehicle. MGs of the 70s, Jaguars of the 70's and 80's, whatever they built that was SH*&ty in the 90's and then the Mini Cooper. I really like the styling, so I am going to hang with this for another month or two...maybe.

 

Sorry for pasting the company HPFP-MINI-COOPER-REBUILT.COM three times. It was pasting white, and I didn't think it was going in post correctly.
So does anyone have the scoop on them?

 

You're unlikely to hear any protest by members here when you say that Mini Coopers can be a royal pain in the behind.

It sounds like you are unsure whether the HPFP or LPFP was replaced by the previous owner. If the HPFP was replaced with a cheap aftermarket version, they can fail fairly quickly.

 

Absolutely and understood. However, the replacement was conducted at a BMW dealership. I would assume it was a BMW OEM part. I can't say if it was low or high however, as CARFAX does not state.

 

I agree!

This is the key point. The diagnostics currently point to an HPFP issue, so you shouldn't assume that the HPFP was recently replaced.

 

And kills me. I decided to go out and look some things over. I cranked it off and of course it’s stumble a little but smoothed out. When I pushed the accelerator pedal it revs well but it is in limp mode so only getting about 80 psi. I used to scan tool to clear the codes and take it out of limp mode. Turned the car off and back on and the fuel pressure instantly shot up to the computers desired pressure. I took it out for some spirited romps and the high pressure pump works flawlessly. It will maintain 1700 psi. It once hit 2000 psi on a really hard pull. It is the start up is killing me. I know mechanical and electronic things can fail intermittently. However, with the pump able to achieve such high pressure this is just a little odd.

 

HPFPs can initially fail intermittently before eventually failing completely.
