What fails inside the HPFP?
The problem with the Mini Cooper S High Pressure fuel pump failing is an internal non return valve which fails and allows pressurized fuel to leak back into the fuel tank and as a result upon start-up has a lack of sufficient fuel to the injectors causing misfiring until the pump has built up sufficient pressure.

And that makes you wonder why nobody is offering a rebuild kit or repair options? I remember back in the day going to the parts store and swapping pumps and alternators for reasonable prices instead of tossing things out.
It is interesting there isn't something like that available, same with an aftermarket performance valve cover option. MINI's are known for performance and modification so I'm curious as to why no shops or MINI companies haven't manufactured alternative performance/rebuild options to issues like these yet.

Sounds like the pump can be rebuilt cheaper than replacing it. But who makes the faulty part and how much labor would go into fixing it? My HPFP went out about a year and a half after I bought the car. Dealership arranged to have it towed there the following day (100 miles, to Scottsdale) and replaced it. I doubt they'd get away with rebuilding it under warranty.
Don't have the skills to answer the viability of a rebuild kit for the pump or not but in terms of fixing a problem and getting the car back on the road, it doesn't make much economic sense for the dealership.
For example on my 09 JCW the turbo failed. But in order to determine that root cause, the dealership goes through a lengthy process based on the CEL codes. The clock is ticking, both for the dealer and also the customer.
For my turbo the dealer went through various component checks and all were good. Then they called and advised the next step was to remove the turbo to see if it is bad.
The charge to pull the turbo was 5 hours of labor. Then they tell you that for 3 additional hours of labor they will bolt on a new turbo and put everything back together.
If you opt for rebuilding the turbo you have the 8 hours plus their parts and labor to rebuild. It is just more efficient to pull a new part and install it.
Today's components are just treated like they are consumables. Just like oil filters. Just more costly.
In the end, I pulled and replaced my turbo DIY and completed the job for less than they would have charged.

The problem is that the price for a two hundred dollar pump is now north of a thousand dollars. The rebuild is probably a few dollars in parts, it isn't a sophisticated device.

I still have pump #1 in the garage. I may tear it apart to see what's inside. Pump #2 (in the car) is on it's way out, the fuel rail pressure is dipping lower and lower on startup, so pump #3 is coming in the near future. Good job Bosch.
If and when I do tear it apart, I'll post detailed pictures of the process and the internals.
I have a HPFP that has gone out. Looking on this site, and in search of a reasonably priced HPFP, I have noticed that there are 2 pumps that look identical. One is about $200-$300, while the second (the one I need) can't be found for less than $850. They look identical, so what is it the difference that justifies a $600 difference in price? I wonder has anyone ever tried the less expensive part in place of the overpriced part? I didn't list the specifics as I'm sure anyone reading this and familiar with this problem knows exactly what I am talking about.
Thanks.
Thanks.
Somewhere in the 2012 year as I recall they changed pumps. It is the older one made by Continental that has seen prices go crazy. The newer ones I think have stayed more reasonable. The old ones were being used up on warranty replacements, recalls, etc. and lots of failures.
At least I think this is what you were referring to.

So is there a difference in the HPFP on a N14 and N18 engine. From what I can see, they look identical? Or is this just price gouging due to the high demand for HPFP after 50K miles?
I have the N18 engine with 57K and HPFP is dying. I cant help but wonder if the 2 pumps are interchangeable?
I thought about that. But without having one in hand and some calipers to measure the key, it's impossible to know for sure.
I agree with you on not trusting the pictures. I was hoping maybe someone with a lot more experience working on mini's than me, had looked at the two and knew what the difference was. I guess I'm just reaching for a way to save $600 if I can!
Thanks again!

Compare the part numbers. Do both parts have the same or different part numbers? The price of the HPFP went up a few months ago so it could be that the one pump that is lower in price has yet to be updated price wise in their database. We had one that was like that and we had to manual update it because it was from a different distributor.
The N18 and N14 HPFP are both high in price and both have different part numbers.

It does appear that both are high in price. And you may well be correct on the sellers not updating their inventory pricing. I looked again today and came across one listed for $380, and when I clicked on it, WHAMMO, $1000. So yes, the prices have gone up considerably as you mentioned. Thanks again for the info!
Thanks Pelican!

Well another issue is that we are really dealing with 3 different pumps here. All keep failing. The N14 had a Continental pump, as well as early N18’s like mine (similar looking, but different parts that are not interchangeable. Then we have the Bosch pump on the later N18’s. Even the Continental pumps are close to $1500 now at the dealership! I’m very lucky that they replaced mine a few months ago event though I was 9000 miles past warranty cut-off, the awesome guys at Seattle Mini’s service dept get it swapped at no cost for me! (You guys ROCK)
I was minutes away from ordering one and called them on a whim, and got lucky! Too bad my turbo was a different story two years ago! But that’s another thread.
So even if it’s the same part that keeps failing, a thermocouple or whatever it may be, that’s 3 versions of it we’re dealing with. I read some of the HPFP threads and saw some guys replaced o-rings and had some promise but never a solution.
Ive seem a few rebuilt Continental pumps on eBay and Amazon, but when you read the reviews, most seem to fail darn near immediately. I saw some that failed within seconds of starting the car. The longest lasting one I read was about 200 miles before it crapped out. So new seems to be the only reliable (sort of) way to get one that is not junk already. It would sure be nice if next time it goes, to find an alternative to the cost of a new one! And while I’m at it let me complain about the valve cover replacement cost as well! Why is there no other options? Where is the aftermarket?
